AI Technical Summary

Problems solved by technology

In the actual rolling production process, buckle and buckle are frequent problems in the rough rolling stand of hot-rolled strip steel production. As a result, the downstream frame cannot be bitten and the steel is scrapped; and the buckled slab may also cause backlash to the equipment, thereby causing production accidents

Abstract

The invention discloses a control method for slab head buckling and warping. The method comprises the following steps: judging whether head warping head and head buckling occur on a slab or not; when the slab is subjected to head warping, load balance compensation is conducted on an upper roller of a roughing mill; and when the slab is subjected to head buckling, load balance compensation is carried out on a lower roller of the roughing mill. According to the control method for slab head buckling and warping, buckling and warping in a slab rolling process can be controlled; slab buckling and warping are avoided; the rolling quality of strip steel is improved; and safe and stable operation of a rolling production line is guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a method for controlling buckling of slabs. Background technique [0002] The slab warping refers to the phenomenon that the strip slab warps upward after it leaves the roll gap of the rolling mill during the rolling process of the strip steel. The phenomenon of downward warping after the roll gap of the rolling mill. In the actual rolling production process, buckle and buckle are common problems in the rough rolling stand of hot-rolled strip steel production. As a result, the downstream frame cannot bite in and the steel is scrapped; and the slab with buckled head may also cause backlash to the equipment, thereby causing production accidents. [0003] For this reason, it has become a technical problem to be solved urgently by those skilled in the art to develop a method for controlling buckling and warping of slabs to control buckling and warping in slab rolling.
