How to improve the efficiency of slag ball drawing?

The cleanliness level is the basic premise to ensure the commodity characteristics of steel, and is also the basic element of manipulating the commodity characteristics in the steelmaking process. Clean steel means that the manipulation of the impurities and elements in the steel can meet the characteristics of the whole process of steel processing and application.

It is easy and feasible to promote high quality iron making by blocking slag and drawing steel. The amount of slag in steelmaking furnace can be greatly reduced and the yield of aluminum alloy can be reasonably increased. It can reduce the slag line corrosion of slag to the ladle and reduce the loss of refractory materials. It can reduce the unqualified rate of steel production caused by the over-standard sulfur and phosphorus composition of liquid steel; It can reasonably improve the recovery rate of liquid steel and generate economic benefits for the steel industry; It can reduce the scouring time and reduce the cost of scouring.

Choosing opportunities is especially important. The key to the success of the actual operation of slag blocking is to grasp the actual operation opportunity of slag blocking. Adding the slag ball too early will cause the plug body to float in the liquid steel level easy to boil out; If the opportunity is added too late, it will cause more vortex slag rolling and slag stopper to immediately plug the outlet and leave more steel in the whole process of falling, and even the situation that the liquid steel has been net and can not lift the furnace when the slag has been blocked in actual operation. After long-term on-the-spot observation and viewing of relevant materials, it is clear that the actual operation opportunity for slag blocking is when the liquid steel is produced to 2/3 of the total output, which ensures the actual operation of slag blocking.
