Well vacuum annealing furnace
Compared well type vacuum annealing furnace and box type furnace, pit type vacuum annealing furnace thermal efficiency is higher than the box-type furnace, its sealing performance is better also, the difference between them in terms of operation is the heating product in a different way.
The well type vacuum annealing furnace is more convenient to operate without the box type furnace, and the maintenance of box type furnace is more convenient.
The box type furnace is horizontal, and the well type vacuum annealing furnace is vertical, so the heat treatment of some of the parts with long shafts is suitable in the well type furnace.
Well type vacuum annealing furnace can be suspended in the furnace to reduce the deflection of the shaft, while the box furnace is not.
The application scope of well type vacuum annealing furnace is introduced as follows:
Well type vacuum annealing furnace top is suitable for deep drawing of stainless steel pieces of warm water equipment, water swelling, pin, medical equipment, stainless steel nails, stainless steel wire the self-contained, pressure riveting pieces, stainless steel bearings, watchcase, strap, cutting tool, micro shaft, tapping drilling, tableware and other stainless steel products under the protection of air control of light annealing, quenching, demagnetization and stainless steel quenching treatment of multi-purpose furnace.
Well type vacuum annealing furnace frame composed of steel welded together, the casing outside the strong convection spheroidizing annealing furnace with channel steel girders, coaming choose cold plate, trolley annealing furnace with channel steel girders, bottom and front and rear end plate to choose medium plate.
The sealing of a well – type vacuum annealing furnace: the car and furnace are sealed with the labyrinth car type annealing furnace structure, and there are automatic sand sealing equipment at the end of the platform. The furnace door is sealed with the roller type compaction and the spring pressure automatically arranged to seal the furnace body some of the excellent firebrick structure to ensure the sealing of the furnace. Some high alumina brick masonry is used in the platform, and the lower part is insulated with insulating brick.
Well type vacuum annealing furnace is widely used in chemical, petroleum, food, metallurgy, machinery, light industry, electric power, shipbuilding, papermaking, mining, pharmaceutical, central heating and other industrial departments of heating, cooling, condensation, evaporation and other technical process.
