Description
Technical Field
The invention belongs to the technical field of metal plate rolling, and particularly relates to metal plate rolling equipment.
Background
The metal blank is pressed through the gap (various shapes) between a pair of rotating rollers, and the cross section of the material is reduced and the length is increased by the compression of the rollers, so that the press working method is the most common production mode for producing steel materials and is mainly used for producing sectional materials, plates and pipes. The method is divided into two types of hot rolling and cold rolling.
Hot rolling at a temperature higher than the crystallization temperature; the following advantages exist for hot rolling:
after hot rolling, nonmetallic inclusions (mainly sulfides and oxides, and silicate) in the steel are pressed into flakes, and layering (interlayer) occurs. Delamination greatly deteriorates the tensile properties of the steel in the thickness direction, and interlayer tearing may occur when the weld shrinks. The local strain induced by shrinkage of the hot rolled sheet weld often reaches several times the yield point strain, much greater than the load induced strain.
The disadvantages are more pronounced in the rolling of thick slabs into thin slabs.
The invention designs the roller to enable the rolled sheet to pass through the up-down extrusion displacement of the upper layer and the lower layer of the original rear plate along the discharging direction in the back thinning rolling process, thereby reducing the distribution of the layered structure formed by hot rolling and optimizing the stress performance.
