Semi-automatic Slag Dart Machine Has A Great Role In BOF Steel Production

Nov. 16, 2018

Semi-automatic Slag Dart Machine is a steelmaking electromechanical equipment used to optimize the production process of converter steelmaking, improve the quality of molten steel and reduce the material consumption of the rear process. The steelmaking process by the slag slag machine can greatly reduce the amount of slag flowing into the ladle during the entire tapping process, so that the quality of the molten steel is significantly improved, the alloy consumption in the latter process is reduced, and the economic benefit is improved.

In converter steelmaking production, a large amount of molten steel slag is produced during smelting in the furnace. The chemical composition of the steel slag is complicated, especially the sulfur and phosphorus elements contained in the steel slag have a great influence on the quality of the steel. After the molten steel is smelted, the amount of steel slag flowing into the package with steel water should be strictly controlled. For this reason, the slag tapping process is usually adopted to prevent the harmful components of sulfur and phosphorus in the steel slag from re-infiltrating into the molten steel in the later process. It is often referred to as “rephosphorization” in the steelmaking process, which affects the quality of the billet. In order to improve the quality of the product and achieve the production of “clean steel”, the slag tapping process is an important link.
