Whether it is used for nitriding, cyaniding, roasting, forging and tempering, annealing, normalizing, etc., the door of continuous heat treatment furnace is open and both ends are open due to the operation characteristics of its workpiece. In this case, first of all, the temperature in the furnace is very difficult to control, because it takes away a lot of heat due to the influence of air flow outside the furnace; secondly, the atmosphere in the furnace is not well controlled, and oxygen continuously enters the furnace, which makes the surface of the workpiece, especially the metal workpiece, easy to produce oxide scale; thirdly, it is very difficult to close the furnace door and require the workpiece to enter and leave the heat treatment furnace continuously.

The use of fepford furnace door sealing curtain (furnace door fire curtain), first is to save energy and reduce consumption, the second is to improve product quality and excellent rate, the third is to optimize the working environment of personnel, which are the three most important functions.
