Abstract

The invention belongs to the technical field of continuous casting and rolling of hot-rolled sheet billets, and provides an energy-saving type hot-rolled sheet billet descaling device and method. The energy-saving type hot-rolled sheet billet descaling device comprises transmission units, descaling units and 2n reciprocating units, n is a positive integer, and the reciprocating units are correspondingly arranged up and down relative to the hot-rolled sheet billets and connected to one set of transmission units; each reciprocating unit is provided with a descaling unit, and the transmission units drive the reciprocating units to rotate in one direction, so that the descaling units move back and forth in the width direction of the hot-rolled sheet billets. According to the energy-saving type hot-rolled sheet billet descaling method, one set of transmission units is used for simultaneously driving more than one descaling unit arranged on the upper layer and the lower layer of the hot-rolled sheet billets to move back and forth along the width range of the hot-rolled sheet billets. According to the energy-saving type hot-rolled sheet billet descaling device, the descaling units move back and forth along the width range of the hot-rolled sheet billets, so that the oxide scales on the upper surfaces and lower surfaces of the hot-rolled sheet billets are removed, and the non-uniformity of descaling is avoided and the failure rate is reduced on the premise of meeting the descaling effect.

Description

technical field [0001] The invention belongs to the technical field of hot-rolled thin slab continuous casting and rolling, and particularly relates to an energy-saving hot-rolled slab descaling device and method. Background technique [0002] In the hot-rolled thin slab continuous casting and rolling unit, before rough rolling the hot-rolled slab, it is necessary to use high-pressure water to remove the oxide layer on the surface of the slab, so as to avoid pressing the iron oxide scale into the hot-rolled slab during rough rolling. , affecting product quality. At the same time, the hot-rolled slab needs to maintain a certain high temperature for rough rolling and subsequent finishing rolling. Therefore, in the process of descaling, it is not desirable to reduce the temperature of the hot-rolled slab too much. [0003] At present, the descaling method adopted is rotary treatment, that is, several groups of rotating nozzles are arranged along the width of the slab. During t...
