Refractories has some slag resistance , called slag resistance is the ability of refractory slag erosion and scour resistance at high temperatures . For this refractory characteristics , I plant experts conducted a comprehensive description of refractory relevant description .
Refractory slag erosion is the most common form of a damaged during use , such as the lining of various furnaces , ladle working lining , blast furnace from the lower body to hearth furnace lining , the lining of many non-ferrous metallurgy , lined with cement kiln wall and other damage to the glass kiln pool , mostly caused by such action . In actual use , about 50% of the damage is due to erosion caused by slag .
According Yixing Keqiang refractories plant experts, refractories and refractory slag resistance of the main mineral composition and chemical structure , and the other also with the nature of the slag and their mutual conditions. High purity refractory materials , improve the chemical composition of mineral products to minimize low-melting material and content of impurities , so that products produced in the liquid phase and with the outside world began to raise the temperature of the reaction is an effective way to improve products, slag resistance .
Furthermore , experts advise, be sure to pay attention to the selection of refractories , refractory and try to use a similar chemical composition of slag , weakening the strength of their reaction on the interface . Such as basic metallurgy furnace refractory lining should use alkaline ; , or try to change the composition of the slag to be used to close the refractory component , is one way of refractory slag resistance improvement . Further , the use of refractory materials , it should be noted that similar chemical properties between the materials to prevent or mitigate the damage to the interface under the condition of high temperature reaction .
