Pit vacuum annealing furnace

Pit vacuum annealing furnace

Suitable for annealing of coiled wire, steel strip, etc. Heating and annealing in a vacuum state, no nitriding, no decarburization. Keep the workpiece bright after annealing. The outer shell of the furnace body is welded by section steel and steel plate, and the furnace is built with ultra-lightweight bricks. The heat preservation layer adopts a mixed structure of aluminum silicate refractory fiber and vermiculite powder to improve the heat preservation performance of the furnace body.

Pit type vacuum tempering furnace

The furnace shell is made of heat-resistant stainless steel plates by close welding, and a fan is installed on the furnace cover to force air circulation to make the temperature and gas in the furnace uniform. The furnace cover is sealed with the flange of the furnace bladder, and the furnace cover is connected with a vacuum device.

Pit-type vacuum tempering furnace shell is welded by section steel and steel plate

The furnace lining is a composite structure made of high-strength ultra-light energy-saving refractory bricks, aluminum silicate fibers, diatomite insulation bricks and asbestos boards. Or (use aluminum silicate refractory fiber module inside, masonry into an energy-saving furnace). The furnace cover lifting mechanism is composed of motors, gear pumps and other components

Pit vacuum tempering furnace

It is mainly used for tempering and annealing of various workpieces in a vacuum-less and non-oxidizing atmosphere. The structure of the well-type vacuum tempering furnace is mainly composed of the furnace body, the furnace liner, the furnace cover, the vacuum device and the temperature control system.

Advantages of deep-well quenching and tempering furnace

The furnace cover and furnace lining of the deep-well pit furnace adopt a full-fiber structure, and the current domestic brand-new standard ceramic fiber blanket is used as the heat insulation material of the furnace. The fiber blanket is a man-made inorganic metal fiber material, and special equipment is used when making it. The furnace lining made into a folded block according to the furnace size also has the advantages of easy installation, good heat preservation performance, fast heating, energy saving, and lower production costs.
