DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot rolling method for producing steel plates from a continuous casting slab. By making rolling possible, the flow of the material is extremely smooth, and the continuously cast coins are sent directly to a hot rolling facility for rolling without cooling, or they are placed in a bag in a heating furnace and heated to a predetermined temperature, then rolled. As a result, there is a slight reduction in the amount of work in progress and energy conservation.

To explain the conventional hot rolling method of continuously cast slabs, firstly, in continuous casting (hereinafter referred to as daqian), slabs of different widths are cast by changing the mold to silk, and in the case of continuous casting, slabs of different widths are cast by changing the mold to silk. It is said that casting is done by changing the width of the mold without changing the width of the mold, but considering the productivity of the butterfly fin, it is common to make a large quantity of the same type of fin and store it in a slab yard or the like. be.

As a result, a large amount of work-in-progress is required, requiring a large storage area, and from an economic perspective, a large amount of work-in-progress is required, and when rolling, there is a large double transportation loss due to having to transport it again over a long distance. .

In addition, heat loss is also large because the heat retained in the lotus coin slab is cooled down. On the other hand, in hot rolling, the parts of the work rolls that come in contact with the scarlet rolled material are worn out, which affects the product shape, so taking into consideration the actual state of roll wear, the roll schedule is set up in advance to maximize the rolling amount for each roll. is common. The roll schedule is generally planned so that rolling is performed in order from wide to narrow in order to suppress the effects of roll wear as much as possible and maintain a good shape and crown of the rolled material. Therefore, it is necessary to wait for the preparation of the rolled slabs to be assigned to each roll. As mentioned above, the width of Yosen slabs is changed in 4-inch increments according to orders, and they are not produced in small quantities. Instead, they are made in large quantities by bulking up pieces of the same width and stored in slab yards, etc., so each roll schedule is changed. It takes a long time to prepare slabs for each width.

In particular, if there are many orders for small lots of a wide variety of products, the waiting period for the art tree will become even worse. As described above, in the conventional hot rolling of lotus coin slabs, it is difficult to directly send the lotus coin slabs to the hot rolling equipment for rolling immediately after casting due to constraints on the roll schedule, resulting in severe stagnation of the material, which lengthens the manufacturing period. The present invention was developed in view of the above-mentioned circumstances, and it is possible to smoothly flow the material from Liao fin to hot rolling without any stagnation, and to effectively utilize the heat retained in the rolling slab. The purpose of this project is to provide a continuous casting/lotus vertical hot rolling method that can handle orders for a wide variety of products and small lots in a short production period. Next, the width of the slab is adjusted using vertical rolls in the order of product required width, and then when hot rolling is performed in the order of width adjustment, work roll breakage is performed based on the predicted wear base according to the width of the material to be rolled and the amount of rolling. A continuous casting series gun hot rolling method characterized by performing schedule-free rolling of a steel plate while predictably polishing the plate part by work roll polishing.

to produce slabs, and then adjust the width of the slabs using vertical rolls in order of product required width,
Subsequently, when hot rolling is performed in the above width adjustment order, the non-rolling portion of the work roll is predictively polished using a work roll polishing bag directly based on the expected wear amount according to the width of the material to be rolled and the amount of rolling, and the steel plate is scheduled free. Continuous casting-continuous hot rolling characterized by measuring the shape and cross-sectional profile of the steel plate at the exit of the finishing rolling mill while rolling, and corrective polishing of the work roll using the work roll polishing device described above based on the nuclear measurement signal.

Furthermore, in addition to predictive polishing, the shape and cross-sectional profile of the steel plate are measured at the exit of the preliminary rolling mill, and based on the measured values, the shape of the roll is corrected and polished by roll polishing to produce a steel plate with a good shape. This correction polishing to adjust the roll shape can be performed between rolling steps, but it can also be performed during rolling. These roll polishing methods predict the roll wear base when rolling a material of a certain width by a certain amount,
The non-threaded portion of the roll is mainly polished by this predicted wear amount. Also, while performing roll polishing and rolling, the shape and cross-sectional profile of the steel plate are measured at the exit of the rolling mill, and the measured values are sent to the computer, and various information that has been input into the computer in advance, such as roll material and dimensions, etc. Work rolls can be polished online along with information, overflow, dimensions, material, etc. of the rolled material.

The work roll 4 of the finishing rolling mill rolls the material to be rolled without wear at the beginning of the technique, but gradually wears out depending on the width of the material to be rolled. Therefore, in the present invention, predictive polishing of the work roll 4 is performed. The wear amount of the roll can be predicted and calculated using the inputs c such as the material of the roll, the steel type of the material to be rolled, the width, and the temperature. Predictive polishing is performed. Furthermore, if necessary, the profile and shape of the steel plate rolled with the predictively polished rolls are measured by a profile meter P and a shape detector F, respectively, and a control device 10' that receives the measurement signals and a roll cracker. The necessity of polishing is determined by calculation together with reference values input in advance and other information, and if polishing is necessary, a correction command is issued to the roll polishing machine 5 to perform the correction polishing. In addition to the above-mentioned aspect, in the present invention, a slab of a constant width is produced in the casting machine 1, and can be made into a desired width using only the vertical rolls 2.

In addition, the width of the constant width slab is adjusted using a sizing mill that can adjust the width and thickness of the slab shown by 9 in the figure.
The final width can be adjusted using the vertical rolls 2. In that case, it is preferable to provide a heating furnace 11 in order to compensate for the heat taken away from the slab by the sizing mill 9 and to ensure an optimal rolling temperature. As explained above, the present invention has a great effect in that steel plates of various widths can be manufactured without stagnation by schedule-free hot rolling that takes advantage of the high productivity of continuous casting.
