Problems solved by technology

[0003] In order to solve such defects, some domestic iron and steel enterprises have adopted the method of increasing the temperature of the slab out of the furnace to solve the defects of "thin lines" and "warped skin", but the effect is not obvious. Surface oxide scale defects, more increase the quality of the strip

Abstract

The invention relates to an E1 vertical roll of a plate strip rolling mill. The slot bottom of a vertical roll slot comprises a groove and an inclined plane. The groove comprises a groove upper inclined plane and a groove lower inclined plane, the groove upper inclined plane is in smooth transition with the groove lower inclined plane, the inclined plane is in smooth transition with the groove lower inclined plane, the length of the part, corresponding to the inclined plane, of the central axis of the vertical roll is L1, the length L1 is larger than h, h is the thickness of a plate blank when a second step of a first rough rolling plain-barreled roll rack is conducted on the plate blank, L1+L2 is smaller than H, H is the thermal state thickness of the plate blank before the plate blank is pressed primarily on the side of the vertical roll, and L1+L2+L3 is larger than H. According to the E1 vertical roll of the plate strip rolling mill, the hole shape of the vertical roll is changed, metal flow at the sharp corner portion of a plate strip and the temperature of the sharp corner portion are changed, and the defect that filaments or peeling is formed is avoided.

Description

technical field [0001] The invention relates to the technical field of strip rolling, in particular to an E1 vertical roll of a strip rolling mill. Background technique [0002] At present, the pass of the vertical roll of the rough rolling E1 of the strip production line adopts the flat roll shape, and the pass of the E1 vertical roll is as follows figure 1 shown. When the slab passes through the E1 vertical roll for side pressure and width reduction, according to the characteristics of the metal flow change at the edge during the rolling process, the sharp corners on the upper surface and side of the slab remain in their original positions (the temperature of the sharp corners is lower than other positions. low), and after being rolled by the horizontal rolls of the first rough rolling flat roll stand, the metal at the sharp corners of the slab is turned over to the upper surface, and at the same time, the iron oxide scales on the sharp corners are also pressed into the s...
