Slag stopper

The converter slag stopper is put into the truck in the domestic converter steelmaking production. A large amount of molten steel slag is produced during smelting in the converter. The chemical composition of the steel slag is complex, especially the sulfur and phosphorus elements mixed with the steel slag have a great influence on the quality of steel. After the molten steel is smelted and tapped, the amount of steel slag flowing into the ladle with the molten steel must be strictly controlled. For this reason, the slag tapping process is usually used to prevent the harmful components of sulfur and phosphorus in the steel slag from re-penetrating into the molten steel in the subsequent process. , Resulting in the “recovery” often referred to in the steelmaking process, which affects the quality of billet products. In order to improve product quality, the production of “clean steel” and the use of slag-retaining tapping technology for converter steelmaking are crucial and critical links. The slag stopper is a kind of 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 back process. The steelmaking process with the slag stopper putting into the vehicle equipment can greatly reduce the amount of slag flowing into the ladle during the entire tapping process to significantly improve the quality of molten steel, reduce the alloy consumption in the rear process, and improve economic benefits.

The DZ-6 converter slag stopper and slag stopper are mainly used to perform and complete the slag stopper ball and slag stop cone when the converter is tapped, so as to improve the slag stop effect and have better economic benefits. It has created necessary conditions for iron and steel enterprises to produce high-quality, high-value-added products and improve market competitiveness. It has good economic and social benefits, and has achieved a successful trial of the slag-retaining process. After industrial testing, the slag stopper is used in combination with the slag stopper, and the hit rate is 100%, and the slag stop efficiency is over 98%.
