Description
Technical Field
The utility model relates to a steel billet turnover device before rough rolling, belonging to the technical field of steel rolling mechanical equipment in the metallurgical industry.
Background
At present, in the steel rolling production of the metallurgical industry, a flame cutting mode is adopted when the continuous casting billet is cut to length, and in the flame cutting process of the continuous casting billet, a cutting nozzle is worn, so that a part of molten iron nodules are easily remained at the bottom of the section of the cut continuous casting billet, and when the steel billet enters a roughing mill for rolling, the steel billet is easily scratched to cause defects, and the appearance quality of a product is influenced. Because the section form of the steel billet is related to the type of a finished product, the steel billet needs to enter a roughing mill in any form according to the rolling variety, the steel billet needs to be subjected to the section conversion of the steel billet according to the specific rolling process requirement, namely, the steel billet is turned over, so that the influence of the steel billet with residual molten iron accretion on the product quality in the rolling process is eliminated, and meanwhile, in order to ensure that the heat of the steel billet is not excessively lost, the steel turning process needs to be rapid, the production efficiency is ensured, and the production yield and the quality are improved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a steel billet turnover device before rough rolling, which can turn a steel billet according to the requirements of a rolling process so as to eliminate the influence of molten iron nodules remained at the bottom of a section after cutting of a continuous casting billet on the product quality in the rolling process and solve the problems in the background technology.
The technical scheme of the utility model is as follows:
the utility model provides a steel billet turn-over device before rough rolling, contains frame, hydro-cylinder, turn-over arm, side shield, support and rollgang, and the cylinder body of hydro-cylinder is fixed in the frame, and the piston rod of hydro-cylinder is together articulated with the one end of turn-over arm, and the other end setting of turn-over arm is in the below of steel billet, the steel billet is located the rollgang before rough rolling on, and the both sides of rollgang are equipped with respectively with steel billet matched with side shield, turn-over arm rotation connection on the support, and the support is fixed in the frame.
The steel turning arm is rotatably connected to the support through a rotating shaft.
And a rotating shaft which is rotatably connected with the steel turning arm and the support is positioned above the conveying roller way.
And a rotating shaft which is rotatably connected with the steel turning arm and the support is close to one end of the steel turning arm hinged with a piston rod of the oil cylinder.
By adopting the utility model, when the steel billet runs to a certain position in front of the roughing mill, the oil cylinder drives the steel turning arm connected with the oil cylinder to act, the steel billet is driven by the steel turning arm to turn, and meanwhile, the side baffle plays a positioning role, so that the position accuracy of the steel billet after turning is ensured, and the steel billet can stably and smoothly enter the rolling mill.
The utility model has the beneficial effects that: the billet can be turned over according to the requirements of the rolling process, so that the influence of molten iron nodules remained at the bottom of the cut section of the continuous casting billet on the product quality in the rolling process is eliminated, the appearance quality and the production efficiency of the product are improved, and the labor intensity of workers is reduced.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a frame; 2. an oil cylinder; 3. a tilting arm; 4. a side dam; 5. a support; 6. a steel billet; 7. a rollgang; 8. a rotating shaft.
Detailed Description
The utility model is further illustrated by way of example in the following with reference to the accompanying drawings.
Referring to the attached figure 1, the steel billet turnover device before rough rolling comprises a rack 1, an oil cylinder 2, a turnover arm 3, side baffles 4, a support 5 and a conveying roller way 7, wherein a cylinder body of the oil cylinder 2 is fixed on the rack 1, a piston rod of the oil cylinder 2 is hinged with one end of the turnover arm 3, the other end of the turnover arm 3 is arranged below a steel billet 6, the steel billet 6 is positioned on the conveying roller way 7 before rough rolling, the side baffles 4 matched with the steel billet 6 are respectively arranged on two sides of the conveying roller way 7, the turnover arm 3 is rotatably connected on the support 5, and the support 5 is fixed on the rack 1.
In this embodiment, referring to fig. 1, the middle of the tilting arm 3 is rotatably connected to the support 5 through a rotating shaft 8, and the rotating shaft 8 is located above the roller conveyor 7 and near one end of the tilting arm 3 hinged to the piston rod of the oil cylinder 2.
In order to meet the requirements of different products on the section in the process of rolling the steel billet, the influence of the defective steel billet on the product quality is eliminated, the steel turnover device plays a decisive role, and the working stability directly influences the production speed and quality.
Referring to the attached figure 1, when a billet runs to a certain position in front of a roughing mill, a control valve of an oil cylinder 2 acts, the oil cylinder 2 executes cylinder rod withdrawing action, the oil cylinder 2 acts to drive a steel turning arm 3 connected with the oil cylinder to act, the steel turning arm 3 is rotationally connected with a support 5 through a rotating shaft 8, so that the steel turning arm 3 rotates by taking the rotating shaft 8 as a rotating center, the rotating center of the steel turning arm 3 is not a shape and position center, the action of the steel turning arm executing side is amplified, the steel turning action is realized by small action of the steel turning arm driving side, and meanwhile, a side baffle 4 plays a positioning role, the accuracy of the position of the billet after steel turning is ensured, the billet can stably and smoothly enter the rolling mill, and the subsequent production is guaranteed.
