Slag-stopper cone storage, Slag-stopper cone , Slag-stopper series
3 month agoThe slag stopper cone is a specialized refractory consumable used for tapping in converter steelmaking. Steel tapping slag cone is manufactured by high-pressure molding of magnesium-based/aluminum-carbon composite raw materials and then fired at high temperatures. Converter slag cone consists of a conical head and a guide rod. A loading machine is required to load the slag-stopping cone into the furnace. The conical head features grooves that break up vortices in the steel flow, separating the slag from the molten steel. This effectively prevents slag-borne phosphorus re-entry and improves the purity of the molten steel. It is widely used in various converter steelmaking production lines.
During the middle to late stages of converter tapping, when only a small amount of molten steel remains in the furnace, the slag-stopping cone is inserted into the tapping nozzle via a loading device;
The slag-blocking cone relies on its own weight and guide ribs for positioning, quickly sealing the tapping hole to isolate the slag from the molten steel;
After the entire charge of molten steel has been tapped, the slag-blocking cone remains in the tapping hole and naturally melts at high temperatures during the next smelting cycle, eliminating the need for additional slag removal.
