Where the use of resistance wire heating furnace, the resistance wire are used to support tile installation (see photo). However, due to small and care props brick, it is easy to put it in the furnace when the parts touch off. Resistance wire in the case of the use of careless brick, not only easy to deformation, and easy lap and short circuit. In the past are to stop the furnace gradually removed from the top before replacing the new brick. This repair furnace method not only laborious, time-consuming and costly, and high cost, seriously affecting the completion of the task. We will be broken off the residual bricks with long brazing pick unplugged, and then coated with refractory mud care brick
