Under the quick development, with open hearth furnaces be obsolesced. The metallurgical industry is stepped to transit into large scale converters. The slag splashing converter maintenance is, after steel is discharged from the converter, blow nitrogen gas with oxygen lance & splash the MgO carrying slag homogeneously to the converter wall. The layer slag on the wall can protect the furnace lining efficiently. After utilization of this technique, the American LTV Steel Inc. has reached furnace campaigns of around 20000 heats. The converter's operation ratio 97%. This technique is being introduced in countries & regions like Germany, Korea, Japan, Taiwan etc.

Many iron & steel enterprises in China is developing their slag splashing converter maintenance techniques. As a result, the furnace campaigns in Taiyuan Steel, Chengde Steel, Chongqing Steel & Ma'anshan Steel company are raised respectively from 1500 heats, 500 heats, 700 heats & 1100 heats to 12000 heats, 1500 heats, 8500 heats & 10200 heats. The all get enormous economic benefits.

One of the key technologies in the slag splashing converter maintenance is the proper control on the MgO content in the furnace slag. Practice proved that to add adequate amount of calcined magneisite briquette (see fax form in attached )is the most effective method go reach this target. Therefore our company have a series of super quality calcined magnesite briquette for slag splashing converter maintenance usage, to meet the demand from customers abroad.
