Middle thick plate production line and production method

Abstract

The invention provides a middle thick plate production line and a production method. The middle thick plate production line comprises a main rolling line comprising a main rolling line output roller, a shear line comprising a shear line input roller and a middle roller arranged between the main rolling line and the shear line, and the middle roller is linearly connected with the main rolling line output roller and the shear line input roller respectively. The main rolling line and the shear line are directly connected by virtue of the middle roller, a motherboard produced by the main rolling line can directly pass through the middle roller and enters the shear line to be sheared, the yield can be increased, and the quantity of the motherboards entering a cooling bed component can be reduced, so that the service efficiency of the cooling bed is improved, and the production efficiency of the middle thick plate production line is further improved.

Description

technical field [0001] The invention relates to the technical field of metallurgical steel rolling, in particular to a medium-thick plate production line and a production method. Background technique [0002] The medium and heavy plate rolling workshop is generally composed of plate processing area, main rolling area, cooling bed area, shearing line and finishing area. The steel plate is heated in the plate adding area, and after rolling and other processes are completed in the main rolling area, it enters the cooling bed area to cool as required, and then enters the shearing line to complete the shearing process. Such as figure 1 As shown, the medium and heavy plate rolling workshop in the prior art generally has the following components: a rolling mill 1, a roller table 2, a pre-leveler 3, a rapid cooling device 4, a hot straightener 5, and a main rolling line output roller table 6 ( Hot straightening machine output roller table), cooling bed area input roller table 7, c...

AI Technical Summary

Problems solved by technology

In this arrangement, all steel plates entering the shear line from the main rolling line must pass through the cooling bed area, and the main problem is that the length of the rolled piece is affected by the width of the cooling bed (the expansion of the cooling bed width is affected by plant design and investment restrictions), which is not conducive to flexible orga
