Abstract

The invention relates to the field of metallurgical industries, and in particular relates to a crystallizer casting powder replacing device and a crystallizer casting powder replacing method. The crystallizer casting powder replacing device comprises a casting powder replacing rake body and a handle; the casting powder replacing rake body is provided with a cavity; a plurality of casting powder guide holes are formed in the bottom wall of the casting powder replacing rake body; one end of the handle is connected to the side wall of the casting powder replacing rake body; and the other end of the handle is a free end. When a sintering layer is too thick or the casting powder is caked, the casting powder replacing rake body is placed on the surface layer of crystallizer casting powder to contain the caked casting powder; due to the fact that the casting powder guide holes are formed in the bottom wall of the casting powder replacing rake body, even if the caked casting powder is contained, part of powdery casting powder enters the casting powder replacing rake body; the casting powder can also flow out from the plurality of casting powder guide holes in the bottom wall; therefore, the crystallizer casting powder replacing device can prevent excessive powdery casting powder from being taken out when caked casting powder is fished; continuous consumption of the casting powder in a crystallizer can be guaranteed; high-requirement continuous casting production can be met; and the quality of steel billets is guaranteed.

Description

technical field [0001] The present application relates to the field of metallurgical industry, and in particular, relates to a mold slag replacement device and a method for mold slag replacement. Background technique [0002] Mold mold slag plays a very important role in the continuous casting process, mainly including: heat insulation to prevent heat dissipation, prevent oxygen in the air from entering molten steel to cause secondary oxidation, absorb and dissolve inclusions floating from molten steel to the interface of steel slag, Forming a lubricating slag film between the mold wall and the solidified shell, filling the air gap between the shell and the mold, and improving heat transfer and other important functions. [0003] Mold slag is divided into powder slag layer, sintered layer and liquid slag layer in the crystallizer. During the continuous casting production process, the mold is vibrated up and down, and the billet moves downward. Due to the existence of negati...
