It is mainly used as a slag protection component regulator for slag splashing and protection of a hundred converters. Because the slag splashing protection requires the slag to have suitable viscosity and refractoriness, the reasonable slag composition of the light-burned magnesia ball is the key to the actual splashing slag protection. Generally, light burned magnesia powder cannot be directly splashed to protect the furnace slag, and the amount of magnesium oxide balls needs to be added to adjust, and at the same time replace the use of dolomite, reduce the amount of slag and increase the MgO content in the slag. Light burnt magnesia powder
Because MgO is a high melting point mineral with a melting point of 2800°C, the increase in the MgO content in the slag will increase the viscosity of the slag and increase the refractory back. The slag is easier to combine with the furnace lining, forming an effective slag protection layer on the Lining life, reducing consumption.
Mainly used as slag protection component regulator for converter slag splash protection. Light-burned magnesia balls are required to have proper viscosity and refractoriness due to slag splashing. Reasonable slag composition is the key to implementing slag splashing. The general slag can not be directly splashed to protect the furnace, and the amount of addition needs to be adjusted, while replacing the use of dolomite, reducing the slag amount and increasing the MgO content in the slag. Because MgO is a high melting point mineral with a melting point of 2800, the increase in the MgO content in the slag will increase the viscosity of the slag and increase the refractoriness. The slag is easier to combine with the furnace lining, forming an effective slag protective layer on the furnace lining, thereby increasing the life of the furnace lining , Reduce consumption.
After adopting this technology, a steel company in the United States now has a furnace age of nearly 20,000 furnaces, and the converter's operating rate has reached 97%. West Germany, South Korea, Japan, Taiwan, etc. are all promoting this process. Many steel companies are also actively developing their own slag splashing furnace protection technology. Among them, Taiyuan Iron and Steel, Chenggang, Chongqing Iron and Steel, Maanshan Iron and Steel, etc. have adopted the slag splash protection technology, and the blast furnace age has changed from 1500 furnaces, 500 furnaces, From 700 furnaces and 1100 furnaces to 12000 furnaces, 1500 furnaces, 8500 furnaces, and 10200 furnaces, economic benefits have been achieved.
