[0002] The honeycomb of the heating furnace is mainly used to preheat the gas and air in the heat storage chamber of the heating furnace of the steel rolling system. Its structure is a 100*100*100mm corundum ceramic honeycomb with 2.5mm diameter air holes inside. Once the honeycomb is damaged or blocked, it must be replaced in time. The daily maintenance time is short. The temperature in the heat storage chamber is high. The temperature of the honeycomb is 300-400 degrees when the heating furnace is running. The operators cannot enter the heat storage chamber to operate. Therefore, it is difficult to replace the honeycomb, the safety risk is high, and the operation efficiency is low.
