Melting aluminum reverberatory furnace door is at furnace to join aluminum and aluminum alloy ，long-term in aluminum ingots and the impact and wear of mechanical equipment， so the refractory is especially important here，According to our company melting aluminum furnace refractory castable experience ,damage principle has the following several： 1：the temperature at the lower part of the furnace is generally below 400℃-500℃，and its damage is mainly caused by mechanical impact of charging and wear of aluminum ingots. 2：the upper part of the furnace mouth is mainly caused by the change of temperature when charging，and the thermal shock damage caused by the alternation of hot and cold.
