The first embodiment is as follows:
referring to fig. 1, fig. 1 shows a schematic flow of a rolling mill control method provided in the present application.
The rolling effect of the rolled piece can be influenced by the steel types of the rolling mill component and the rolled piece, so that the component information of the rolling mill component and the steel type information of the rolled piece need to be acquired in order to ensure that the shape of the rolled piece is close to the roll pass of the rolling mill after the rolled piece is discharged from the rolling mill.
The rolling mill component in the present application may be a component in the rolling mill that affects the rolling effect. Optionally, the rolling mill components comprise a mill stand, a roll, a screw down device, a target guide and a cross beam; the part information of the rolling mill stand comprises stand rigidity and stand material, the part information of the beam comprises beam rigidity, beam material and beam height, the part information of the roller comprises roller size and roller material, the part information of the screw-down device comprises screw-down precision and screw-down device material, and the part information of the target guide comprises bearing clearance, bearing material, target passage opening size and target passage opening component material; the target passage opening is a passage opening which is close to the roller in a rolled piece passage of the target guide, namely the target passage opening is adjacent to the roller, and the rolled piece enters the roller after coming out of the target passage opening or the rolled piece enters the target passage opening after coming out of the roller.
The rolling stand is a rolling stand used for mounting all parts in a working stand such as a roller, a screw-down device, a guide and guard and bearing all rolling force, so that the rolling stand is an important part in a rolling mill and has high requirements on rigidity and material. The rolling mills in the bar rolling production line can be divided into a roughing mill group, a middle mill group, a pre-finishing mill group and a finishing mill group, the rolling mills belong to different mill groups, the rigidity and the material of the mill frames are different, the stress of the rolled pieces is different, and the change of the rolled pieces after passing through the rolling mills is different, so that the rigidity and the material of the mill frames need to be considered when the application acquires the moving amount of the roller, the target guide and the target guide cross beam. The rigidity refers to the ability of a material or a structure to resist elastic deformation when stressed, and is an indication of the difficulty of elastic deformation of the material or the structure. Alternatively, the material of the rack can be represented by the grade of steel corresponding to the rack.
The roller is the main part that makes the rolled piece produce continuous plastic deformation in the rolling mill, also is the part that directly influences the rolled piece rolling effect, and roller size and roller material are different, and the change that the rolled piece took place after the roller is different, and in addition, its wearing and tearing condition of the roller of different materials is different, therefore the roller material still can characterize the wear characteristic of roller, consequently, need consider when this application obtains the displacement of roller and obtain roller size and roller material. Optionally, the roll dimensions include roll barrel diameter, roll barrel length, roll neck diameter, and roll neck length; the material of the roller can be represented by the grade of steel corresponding to the roller.
The screw-down device is the core device of the rolling mill, and whether the performance of the screw-down device is good or not determines the quality of the strip, and is used for controlling the movement of the roller and adjusting the roller gap of the roller. The rolling precision of the screw-down device directly influences the precision of the movement amount of the roller, and in addition, the material of the screw-down device can represent the deformation degree of the screw-down device when being stressed, the deformation degree is different, and the movement amount of the roller is different, so the rolling precision of the screw-down device and the material of the screw-down device need to be considered when the movement amount of the roller is obtained. Alternatively, the depressing accuracy of the depressing means may be a screw pitch. It should be noted that the component information of the depressing means may further include rigidity.
The guide is a component which is installed before and after the roller in the rolling process to ensure that the rolled piece accurately and stably enters and exits the roll pass according to the set direction and state. The target guide comprises a rolled piece channel, the rolled piece channel is provided with two channel openings, the channel openings close to the rollers can be used for straightening, clamping, righting and the like of the rolled piece, and further the shape of the rolled piece after passing through the rolling mill can be influenced, so that the channel openings close to the rollers are determined to be the target channel openings.
The size of a target passage port and the material of a target passage port component in the target guide affect the movement amount of the target guide, the larger the size of the target passage port is, the larger the movement amplitude of the target guide can be, and the lower the accuracy requirement of the movement amount of the target guide is, otherwise, the smaller the movement amplitude of the target guide is, the higher the accuracy requirement of the movement amount of the target guide is, namely, the size of the target passage port affects the accuracy of the movement amount of the target guide; the material of the target passage port component can represent the deformation degree of the component when stressed and the abrasion characteristic of the component, namely the material of the target passage port is different, and the rolled piece is changed differently after passing through the target passage port; therefore, the size of the target passage opening and the material of the target passage opening component need to be considered when the moving amount of the target guide is obtained.
Optionally, if the target passage port is box-shaped, the characterization parameters of the size of the target passage port are length, width and fillet radius; if the target passage opening is oval, the characterization parameters of the size of the target passage opening are the long axis length and the short axis length; if the target passage opening is circular, the characteristic parameter of the size of the target passage opening is the radius.
The moving amount of the target guide comprises a moving amount in the horizontal direction and a moving amount in the vertical direction, and the moving of the target guide in the vertical direction is realized through a cross beam of the target guide, namely the moving of the target guide in the vertical direction can be realized by adjusting the height of the cross beam, so that component information of the cross beam is required to be obtained, the rigidity of the cross beam is different, and the deformation degree of the cross beam under stress is different; the material of the cross beam can also represent the deformation degree of the cross beam under stress, and the rigidity is combined with the material, so that the obtained deformation degree of the cross beam under stress is more accurate; when the cross beam needs to be adjusted to a certain height, the current height of the cross beam is different, and the corresponding movement amount is different; therefore, the beam rigidity, the beam material and the beam height need to be considered when the application acquires the moving amount of the beam. Alternatively, the height of the cross beam may be acquired with the mill base as a reference plane.
The main function of bearing is to support the mechanical rotator, reduce the coefficient of friction in its motion process, and guarantee its rotation precision, target passway mouth subassembly is the mechanical rotator in this application, the bearing is used for supporting the mark passway mouth subassembly in the guide, bearing clearance indicates that the bearing is when not installing in axle or bearing box, fix one side of its inner circle or outer lane, the amount of movement when then being not fixed one side is radial or axial displacement, namely bearing clearance can influence the size of target passway mouth, consequently, bearing clearance and bearing material can influence the size precision of target passway mouth, consequently, still need consider bearing clearance and bearing material when obtaining the amount of movement of target guide.
Optionally, if the rolling mill is a rough rolling mill or a medium rolling mill, determining the target guide as an inlet guide and/or an outlet guide of the rolling mill; and if the rolling mill is a pre-finish rolling mill or a finish rolling mill, determining the target guide and guard as an inlet guide and guard and an outlet guide and guard of the rolling mill.
The rolling mill belongs to different units, the rolling requirements are different, and the rolling requirements of the rough rolling unit and the middle rolling unit are lower than those of the pre-finishing rolling unit and the finishing rolling unit, so that if the rolling mill is a rough rolling mill or a middle rolling mill, the target guide can be at least one of an inlet guide and an outlet guide, and if the rolling mill is a pre-finishing rolling mill or a finishing rolling mill, the target guide comprises the inlet guide and the outlet guide.
The rolled pieces have different steel types and different carbon contents, and the corresponding properties such as strength, hardness, plasticity, toughness and the like are different, so the steel type information of the rolled pieces needs to be considered when the rolling mill is controlled. Optionally, the steel grade information of the rolled piece may be a steel grade number corresponding to the steel grade.
102, acquiring section information of a rolled piece processed by a rolling mill at the current moment; and obtaining the rolling temperature at the entrance and the exit of the rolling mill at the current moment.
Optionally, in order to adjust the shape of the rolled piece in time, the section information of the rolled piece at the outlet of the rolling mill at the current moment can be acquired; the section information of the rolled piece is the main basis for controlling the rolling mill, and the purpose of controlling the rolling mill is to make the shape of the rolled piece processed by the rolling mill close to the roll pass of the rolling mill.
Optionally, acquiring a cross-section diagram of the rolled piece processed by the rolling mill at the current moment; section information is determined based on the section map, including but not limited to shape information and size of the section. In an optional embodiment, a cross-sectional view of a rolled piece at an outlet of a rolling mill at the current moment is acquired; the acquisition mode of the cross-section diagram can be arrangement of a radiation source (for example, the radiation source is arranged right above the outlet of the rolling mill), the radiation source emits radiation to irradiate the rolled piece, and the cross-section diagram is acquired based on a three-dimensional imaging technology.
The rolling temperature at the inlet and the outlet of the rolling mill also influences the rolling effect, the rolling temperature is different, and the rolled piece is changed differently after passing through the rolling mill, so that the rolling temperature at the inlet and the outlet of the rolling mill at the current moment needs to be obtained when the movement amounts of the roller, the target guide and the cross beam are obtained.
103, determining the movement amount of a roller at a target moment, the horizontal movement amount of a target guide and the vertical movement amount of a cross beam of the target guide according to the component information, the steel grade information, the section information and the rolling temperature; the target time is a time after the current time.
Optionally, determining the moving amount of the roll at the target time, the horizontal moving amount of the target guide, and the vertical moving amount of the beam of the target guide according to the component information, the steel type information, the section information, and the rolling temperature, includes:
inputting the component information, the steel grade information, the section information and the rolling temperature into a first information processing model to obtain the moving amount of a roller, the horizontal moving amount of a target guide and the vertical moving amount of a cross beam;
or determining the moving amount of the roller, the horizontal moving amount of the target guide and the vertical moving amount of the cross beam based on the first corresponding relation and the first data set;
the first corresponding relation comprises a mapping relation between a first data set and a second data set, the first data set comprises component information, steel grade information, section information and rolling temperature, and the second data set comprises the moving amount of a roller, the horizontal moving amount of a target guide and the vertical moving amount of a cross beam.
Wherein the first information processing model may be a neural network model; it should be noted that each rolling mill corresponds to one first information processing model.
Optionally, the mapping relationship between the first data set and the second data set included in the first corresponding relationship may be continuously updated, that is, a new mapping relationship may be added, or an existing mapping relationship may be replaced with a better mapping relationship. For example, a new mapping relationship, such as the mapping relationship between the first data set A3 and the second data set B3, may be added to the existing mapping relationship between the first data set a1 and the second data set B1 and the mapping relationship between the first data set a2 and the second data set B2; or, a better mapping relationship may be used to replace the existing mapping relationship, for example, the mapping relationship between the first data set a1 and the second data set C1 is added, and the shape of the rolled piece processed by the rolling mill after the adjustment of the roll, the target guide and the cross beam according to the second data set C1 is closer to the roll pass than the shape of the rolled piece processed by the rolling mill after the adjustment of the roll, the target guide and the cross beam according to the second data set B1, and then the mapping relationship between the first data set a1 and the second data set C1 is used to replace the existing mapping relationship between the first data set a1 and the second data set B1.
It should be noted that, determining the movement amount of the roll at the target time, the horizontal movement amount of the target guide, and the vertical movement amount of the cross beam of the target guide according to the component information, the steel type information, the section information, and the rolling temperature is a process of constantly acquiring the movement amounts, that is, when a rolled piece passes through the rolling mill, the roll, the target guide, and the cross beam are constantly adjusted. For example, if the current time is the first second, the target time may be the second; the current time is the second, and the target time may be the third second.
And respectively adjusting the roller, the target guide and the cross beam at the target moment according to the determined movement amount of the roller, the horizontal movement amount of the target guide and the vertical movement amount of the cross beam of the target guide, so as to ensure that the shape of the rolled piece processed by the rolling mill is close to the roll pass. If the determined moving amount of the roller is zero, the roller is not adjusted at the target moment; if the determined horizontal movement amount of the target guide is zero, the target guide is not adjusted at the target moment; and if the determined vertical movement amount of the cross beam of the target guide is zero, the cross beam is not adjusted at the target moment.
The rolling effect of the rolling mill on the rolled piece can be adjusted in time, the rolled piece is guaranteed to be close to the roll pass of the rolling mill in shape after the rolled piece exits from the rolling mill, subsequent forming of the rolled piece is facilitated, and then the quality and the yield of finished products of bars are improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by functions and internal logic of the process, and should not constitute any limitation to the implementation process of the embodiments of the present application.
