Continuous casting slab descaling device

Abstract

The invention provides a phosphorus removal device for continuous casting slabs. The phosphorus removal device is mainly composed of two steel brush rolls, a rotating stand, a steel brush roll driving system, a rotating stand driving system, a swinging frame, two swinging hydraulic cylinders and a set of water flushing devices. The swinging frame is installed inside a continuous casting slab runout table through two swinging frame bearing pedestals, the rotating stand is supported by a steel brush roll driving input shaft in the steel brush roll driving system and a rotating stand driving input shaft in the rotating stand driving system, the two swinging hydraulic cylinders support the steel brush roll driving input shaft and the rotating stand driving input shaft respectively, and the steel brush roll driving input shaft and the rotating stand driving input shaft are symmetrically installed at the outward-extending ends of two swinging arms of the swinging frame. According to the phosphorus removal device, the steel brush rolls are adopted for performing continuous rolling brushing on the upper and lower surfaces of the continuous casting slabs, then scale is removed through water flushing, and therefore the quality of the supplied continuous casting slabs is improved. The phosphorus removal device is simple in structure and is more suitable for being additionally arranged inside an original continuous casting slab runout table without affecting the structure of the original runout table.

Description

technical field [0001] The invention relates to metallurgical continuous casting equipment, in particular to a continuous casting slab descaling device. Background technique [0002] In the rolling production line, especially in the continuous casting and rolling production line, there is iron scale on the surface of the continuous casting billet before entering the heating furnace, especially the oxide scale on the lower surface. When the continuous casting billet passes through the heating furnace slowly, the oxidation The iron sheet will stick to the furnace roll ring of the heating furnace, destroying the shape of the lower surface of the continuous casting slab, causing serious quality problems such as warping and pockmarking on the surface of the rolled slab, and thus affecting the quality of the next rolling process. It is necessary to add descaling equipment in the billet roller table of the continuous casting production line, that is, a continuous casting billet des...
