Forging technology and development design of slag ball

Slag ball is a round ball which is plugged at the end of the steel outlet to block the slag flow into the steel ladle. In 1972, Japan Nippon Steel Company created the invention, the basic principle is to use the relative density of slag ball close to the middle of steel and slag (generally 4.2-4.5g/cm3), when the steel will be finished, plug the steel mouth to block the slag flow into the steel ladle, the appearance of the slag ball is spherical, and its management is generally made of pig iron block, pig iron pin pressing block, small waste slab and other raw materials as the frame. The external refractory mud can be coated with high aluminum fireproof concrete, heat preservation brick powder as admixture of high aluminum vanadium clay refractory concrete or magnesium refractory mud. If the processing technology of slag blocking is considered, the structure should be simple and the cost is cheap. Liaoning slag ball price

Fully considering the problem of corrosion of the steel outlet, the diameter of the slag ball should be slightly larger than the diameter of the steel outlet to have the effect of slag blocking. The slag ball is generally invested when the steel content is 1/2-2/3, and the slag blocking accuracy is high.

Steel furnace series of product resistant materials including furnace resistant materials and slag resistant materials, although this is a relatively simple commodity, but with the type and quality of iron-making products continue to improve the provisions, the provisions of furnace and slag resistant products are becoming higher and higher, in order to integrate into the development trend of iron-making provisions as soon as possible, Taidong enterprises have successfully developed and designed a large number of steel furnace filler, barbed slag stopper, magnesium slag stopper rod, soft plastic slag stopper and other products.

In which a large number of charging materials have rapid automatic discharge, calcination time is short, ash washing corrosion resistance, the use of more than 100 furnace; Due to the quality of the spinoid slag stopper, the dissolution and discharge method of the spinoid slag stopper is changed, and the actual effect of the slag stopper is significantly better than that of the general polyhedral slag stopper. Magnesium slag stopper rod has high corrosion resistance to acid slag and can not fall down for a long time in dissolving. It is mostly used in smelters of special steel materials. Soft plastic slag stopper is a new upgraded product developed and designed by enterprises. According to the equipment, it can block the steel outlet, which can reasonably stop the slag in the early stage of the steelmaking furnace, and the self-opening rate is 100, laying the foundation for the development and design of new steel grades.
