Liquid ironslag extractor

Abstract

The invention belongs to the technical field of steel metallurgy, and provides a liquid iron slag extractor. The liquid iron slag extractor comprises a workbench, the workbench is provided with a movable base, and the movable base comprises a screw rod sleeve, a base body, a screw rod motor and a pulley; the liquid iron slag extractor further comprises a first motor fixed to a supporting base, a first conveying mechanism connected between the first motor and a turntable and a slide block base which is arranged on a slide rail and can slide along the slide rail; the liquid iron slag extractor further comprises a slag extracting arm, a slag extracting mechanism is arranged at the front end of a fishing arm, a horizontal rotary shaft arranged at the tail end of the fishing arm is rotatably connected with the slide block base, the slag extracting mechanism comprises a hanging frame, a slag extracting claw is connected to the lower portion of the hanging frame, the hanging frame is providedwith a hydraulic driving device driving the slag extracting claw to move, a second motor is fixed to the slide block base, and a second conveying mechanism is connected between the second motor and the rotary shaft. The liquid iron slag extractor is simple in structure, can effectively improve the slag extracting efficiency and achieve automated slag extracting.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a molten iron slag removing machine. 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 pretr...

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 machine has a complex structure, large volume, high price, and low slag removal efficiency, which cannot meet the needs of iron and steel metallurgical production
