Hermetical box-type quenching furnace


  • 01The walls and top of furnace use refractory fibers structure with features of low thermal storage,quick temperature increasing of empty furnace and good effects of heat preservation.
  • 02The furnace door is compressed independently to get good sealing property,so that can ensure less leaking of protective atmosphere under a certain press in the furnace.
  • 03CH4O flow are setted under an alarm device to ensure the workpieces will not be over standard oxidation during the heat treatment period.
  • 04Our equipment uses automatic quenching system to make the processing accomplished full-automaticlly and no need for human’s manual operations during the whole producing.
  • 05The equipment can take and execute the processing records from the equipment of upper processing to ensure the heat treatment quality of the same workpieces during the producing.



Brief introduction:

Push-up organization for materials in-and-out.The workpieces can be directly put in the charging basket and no need for charging tray.Big size workpiece will be put directly into the furnace with no charging basket. Heating chamber uses composite lining with high-temperature-resistant ceramic fibers and heave bricks to ensure heat insulation effects. CH4O and N2 are put in the furnace as protective medium to reduce workpieces oxidation.The quenching sink is located in the pit under the earth with the devices of stir and spray.
Our equipments are under joint controlled by industrial PLC and numerical instruments,user’s programs are easy to use and operate. The in-and-out of workpieces and processing execution are all realized full-automaticlly,Processing parameters can be chosen and setted on industrial personal computer.No workers are needed during the producing period and only load-and-unload operations need human labors.

Equiptment functions:

Solid solution for stainless steel,middle soften for nickel alloy and precision alloy,quenching for soft state for finished products.
