In the modern metallurgical industry, blast furnace and hot blast stove are the core equipment, and the high temperature environment in the operation process has extremely high requirements for refractory materials. As a special refractory form, unshaped refractory is widely used in blast furnace and hot blast stove because of its unique advantages.
Blast furnace is one of the main equipment in the metallurgical industry, used for smelting iron, manganese and other metals. Its internal environment is extremely harsh, need to withstand high temperature, high pressure and chemical erosion and other multiple tests. The hot blast stove is the key equipment to provide hot blast for the blast furnace, and its temperature control is very important for the smelting process of the blast furnace. Therefore, the choice of refractory materials for these two types of equipment is very important.
Unshaped refractory is a kind of non-preformed refractory, which has excellent high temperature resistance, chemical erosion resistance and good construction performance. The material can be customized according to actual needs and can be flexibly applied to various parts of blast furnaces and hot blast stoves.
Application of Unshaped Refractory in Blast Furnace and Hot Blast Stove
1. Blast furnace application In blast furnace, unshaped refractory materials are mainly used for lining, furnace bottom, iron outlet and other parts. These parts need to withstand high-temperature molten iron, slag erosion and chemical erosion, so the refractory material is required to have excellent high temperature resistance, chemical erosion resistance and good thermal shock resistance. Unshaped refractories can meet these requirements and effectively improve the service life of blast furnaces.
2. The application of hot blast stove in hot blast stove, unshaped refractory material is mainly used for furnace, burner and other parts. These parts need to withstand high temperature flame baking and hot air scouring, requiring refractory materials with good high temperature resistance, thermal conductivity and thermal shock resistance. The unshaped refractory has good plasticity and construction performance, which can meet these requirements well.
