It is mainly used as slag protection composition regulator for slag splashing and furnace protection of 100% converter. Because slag splashing requires proper viscosity and fire resistance of slag, Light burned magnesium ball Reasonable slag composition is the key to solid slag splashing. Generally, the slag can not be directly splashed to protect the furnace, and a certain amount of magnesium oxide balls need to be added for adjustment. At the same time, it can replace the use of dolomite to reduce the amount of slag and increase the content of MgO in the slag.
As MgO is a mineral with high melting point, the melting point is 2800 ℃, and the increase of MgO content in the slag will increase the slag viscosity, improve the refractory recovery, make it easier for the slag to combine with the furnace lining, and form an effective slag protective layer on the furnace lining, thus improving the service life of the furnace lining and reducing consumption.

After adopting this technology, an American steel company has nearly 20000 heats, and the operation rate of converter has reached 97%. West Germany, South Korea, Japan, Taiwan, etc. are carrying out this process. Many iron and steel enterprises are also actively developing their own slag splashing furnace protection processes. Among them, Taiyuan Iron and Steel Group Co., Ltd., Chengde Iron and Steel Group Co., Ltd., Chongqing Iron and Steel Group Co., Ltd., Maanshan Iron and Steel Group Co., Ltd., since the slag splashing furnace protection process was adopted, the high furnace life has increased from 1500, 500, 700, 1100 to 12000, 1500, 8500, 10200, respectively, and has achieved huge economic benefits.
