Novel slag collection device

Abstract

The invention belongs to the technical field of ferrous metallurgy. A novel slag collection device comprises a portal frame and a slag collection mechanism arranged on the portal frame. The slag collection mechanism comprises a hanging bracket. A slag claw is connected with a lower portion of the hanging bracket, a hydraulic drive device driving the slag claw is arranged on the hanging bracket. The novel slag collection device is used for working on slag collection of ladles, and a structure of the novel slag collection device is simple. The slag can be quickly taken out and the efficiency ofthe slag collection is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a novel slag removal device. Background technique [0002] The iron and steel industry is the basic industry of the national economy. Under the situation of the rapid development of the national economy, my country's iron and steel industry has shown a trend of leapfrog development in recent years. At present, the overcapacity of the steel industry and the low efficiency of the steel industry have become huge challenges that hinder the development and progress of the steel industry. In this environment, the concept of low-cost and high-efficiency production has gradually penetrated into all aspects of steel production. Steel slag is an inevitable by-product in the iron and steel metallurgical process, accounting for about 10% of iron and steel production. The basic process of modern steelmaking production is: blast furnace - hot metal pretreatment ...

AI Technical Summary

Problems solved by technology

Because the molten iron slag brought into the blast furnace during the process of mixing molten iron and the desulfurization slag produced during the desulfurization process of the molten iron pretreatment in the ladle contain a large amount of harmful substances such as sulfur, these slags will seriously cause serious production problems under the high oxidizing condition of the converter. Adverse effects, resulting in increased subsequent production costs, therefore, the slag on the molten iron surface must be removed before the molten iron is blended into the converter

However, the existing slag removal device has a complex structure and low slag removal efficiency, which cannot meet the needs of iron and steel metallurgical production
