How to check if the lining of box-type resistance furnace is damaged

The lining of the box-type resistance furnace is made of refractory ceramics. It is in direct contact with the heating material. The function of the lining is to withstand high temperatures. It is isolated from other high-temperature electric furnace components under high temperature conditions, so that other components will not be damaged by high temperature. At the same time, the furnace lining also has good insulation performance, reduces heat loss, and improves the heat utilization rate of the electric furnace.

Once the high-temperature electric furnace lining is damaged, if it cannot be repaired in time, other parts of the electric furnace will be damaged. Therefore, we must always check the damage of the electric furnace lining. The specific inspection method is to use the characteristic of stress fluctuation signal to be very sensitive to structural defects, and to inspect the lining of the box-type resistance furnace. Reflection, refraction, scattering and mode conversion will occur, so that it can be determined whether there are cracks or voids in the lining of the high-temperature electric furnace.
