The mixer is mainly used for long-term storage of hot metal and maintain appropriate temperature of iron smelting . When working,generally the temperature in mixer keep 1350 degree temperature and furnace shell is 300-400 degree. When pouring into the hot metal mixer, because of the larger gap, hot metal will produce mechanical impact on the furnace lining.In addition, in order to keep the molten iron temperature in the furnace, the fuel must be injected into to take the flame heating, which also has a certain thermal stress effect on the lining material. According to the mixer working environment and damage reason, it can be analyzed that for the refractory material , it need high mechanical strength, high slag resistance, good thermal shock resistance, low thermal conductivity and small reheating linear change. Refractories are often used magnesia brick, magnesia chrome brick, high alumina brick , clay brick and refractory filler. At the same time as the mixer h...
