Slag has both positive and negative effects in large scale BOF Steelmaking. It absorbs sulphur and binds the phosphorus from the steel. However, slag attacks the refractory lining of the vessel, while manganese and iron oxides in the slag lead to yield losses.So a careful choice between the conflicting elements associated with slag formation is necessary for the optimization of the steelmaking process.
Slag formation in the top blown BOF is described in short. One of the important aspects is the rate of dissolution of lime CaO, added to the converter as soft burnt lime, is metallurgically active only when dissolved in a liquid slag.
As we all know, Large Scale BOF Steelmaking need to optimization the steelmaking process.And you need some equipment,such as slag dart, Slide Gate Plate,Nozzle,etc. And the slag dart dispatching machine is a special device used for optimizing the production of BOF steelmaking. It improves the quality of the steel by reducing the slag mixed into the ladle and reducing the loss of ferroalloy.
Anhui Yuntian Metallurgy Technology Co., Ltd is a leading manufacturer of sliding gate system, slag dart and its dispatching machines in China. we can providet the euqipment machine to proper regulation of sulfur and phosphorus content in the converter steelmaking process produces high-grade molten steel, raising alloy yields while limiting slag byproducts. This highly beneficial procedure can effectively utilize slag for furnace protection and aid in the complete draining of molten steel.
