Sealed box furnace into the furnace technology

1. When everything is ready to pass the inspection before working furnace heating, when the the muffle furnace temperature greater than 750oC, only through endothermic atmosphere, the furnace gas positive pressure, and then lit the fire curtain and front room row of net operating.
2. Until the furnace heated to 930oC, the curtain of fire lit, the part is available into the furnace.
3. Quenching lifting mechanism, is expected out baskets channel, is also quenched, pre-cooling, and drain fixture position of the lifting mechanism and process requirements, generally on the platform below the first material basket quenching oil cooling, the material on the above platforms baskets workpiece pushed into the carburizing furnace heating, close the inner door, the third basket pushed the above platform into the front room, along with the net emission of decontamination preheating, under the platform material basket oil the Lek best baked, the inner door is opened first two baskets, baked quenching, and three baskets into the box furnace carburizing, and so on ad infinitum.
4. If the workpiece quenching, the baked air cooling, the material basket should be placed on the platform, pre-cooling, until the next platform material basket furnace installed, let the platform material basket fell baked.
5. Fire curtain door must seal the inner door seal fire curtain shall ensure that the furnace positive pressure, oil and gas will not be admitted.
