Refractory brick for blast furnace hearth is a kind of raw material with very good fireproof properties, it can be very well used in high temperature natural environment, so it is often used in various high temperature kilns and furnaces. In order to better apply the refractory bricks for iron-making blast furnace hearths, let everyone know what harm the application of refractory bricks suffers from.
The inner space of the smelter is lined with refractory bricks for the hearth of the iron-making blast furnace. It immediately touches the molten steel, and the refractory brick lining of the hearth is damaged by various factors, which can be classified into two categories: one is the In the whole process of iron blast furnace smelter, its own characteristics are clear and continuous elements, one is the structural element of refractory brick walls. As a refractory brick manufacturer, REWELL refractory materials try to design a good refractory brick shape and control the wall structure of refractory bricks to alleviate the damage to the refractory brick lining of the hearth during the whole process of the iron-making blast furnace smelter.
For a factor, there are three key levels, one is high temperature; one is the washing and abrasion of mechanical equipment of molten steel and slag iron; the organic chemical corrosion of the compounds in molten steel and slag iron to the lining of refractory bricks. Under the high temperature natural environment, refractory bricks are used for the lining of the hearth. If the high temperature of the main hearth exceeds the application temperature of the refractory bricks, the refractory bricks will be corroded; the mechanical equipment of molten steel and slag iron flushes the hearth, and the work inside and outside the hearth when iron is tapped. The pressure will lead to the wear of the hearth lining; the corrosion of FeO and MnO contained in molten steel and slag iron endangers the consumption of the hearth refractory brick lining. These three levels are all difficult to avoid in the whole process of the smelter. Destruction of the lining.
