Mold powder automatic adding system for crystallizer

Abstract

Provided is a system for automatically adding covering slag for a crystallizer. The system comprises a control system, two material bins (1), a material conveying pipe (3), a rack (4), a robot (5), a screw conveyer (8) and an infrared detection device, wherein the rack comprises an upper rack and a lower rack; the material bins, the material conveying pipe and the robot are arranged from top to bottom, the material bins are fixed to the upper rack and connected to the material conveying pipe, the material conveying pipe is connected to the screw conveyer, and the screw conveyer is fixed to the robot; the robot is hung upside down below the lower rack, and the robot can transversely move along the lower rack; and the control system is respectively connected to the infrared detection device, the material bins, the robot and the screw conveyer. The system realizes intelligent and automatic slag addition without manual intervention. With the two material bins, switching between various covering slags is realized, improving the slag replacement efficiency. The robot is hung upside down for slag addition, solving the problem of the equipment occupying a large space.

Description

technical field [0001] The invention relates to the field of mold slag adding to a crystallizer, in particular to a system for automatically adding mold slag to a mold. Background technique [0002] The basic functions of mold powder are: to protect the molten steel on the meniscus of the mold from the secondary oxidation of the air; it has good spreading performance and heat insulation performance to prevent the liquid steel surface from solidifying or encrusting; it can well absorb the floating to Non-metallic inclusions on the meniscus; control the speed and uniformity of heat transfer from the slab to the mold to reduce thermal stress; have a good function of lubricating the slab so that it can be pulled out of the mold smoothly. [0003] Most of the existing automatic slag adding systems are rocker arm type or robot ground walking type, which occupy a large space and cover a large area of ​​operation. In the narrow space of the crystallizer, personnel cannot move around...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing automatic slag adding systems are rocker arm type or robot ground walking type, which occupy a large space and cover a large area of ​​operation. In the narrow space of the crystallizer, personnel cannot move around normally. Once an accident occurs, it will be greatly hindered, which is not conducive to safety. production, and cannot form a true closed-loop control
