Problems solved by technology

[0002] As we all know, in the process of heating and smelting steel, in order to remove impurities such as sulfur and nitrate, it is necessary to add desulfurization and denitrification agents to molten steel, so that impurities such as sulfur and nitrate can solidify and form residues. Smaller, the residue usually floats on the surface of molten steel. In order to avoid the impact of residue on the purity of molten steel, the residue needs to be removed and cleaned. The existing method of removing slag is usually carried out manually by workers, but this method of removing slag is cumbersome. , consumes more manpower and time, and there are more residues in the molten steel, which easily affects the quality of molten steel. At the same time, due to the high temperature of molten steel, it is easy to cause burns to workers

Abstract

The invention relates to the technical field of steel smelting, in particular to a safe and reliable molten iron pretreatment automatic slagging-off method and system. The system comprises an inclination mechanism, a collection vehicle, an oscillation mechanism, an arc-shaped reciprocating type scraping mechanism, a pushing mechanism and a slagging-off device. According to the slagging-off manner, the automation degree of slagging-off work can be effectively improved, the slagging-off manner is simplified, manpower and time are saved, the working efficiency is improved, residues in a ladle are effectively removed, the slagging-off effect and the purity of molten steel are effectively improved, meanwhile, the situation that workers are scalded by the ladle during manual slagging-off is avoided, and practicability is improved.
