The role of vacuum tempering furnace and desktop annealing furnace

The vacuum pump heat treatment of the vacuum tempering furnace is the comprehensive technology that separates the two technologies of vacuum technology and heat treatment, which means that all and part of the heat treatment process is terminated under the condition of the vacuum pump.

The vacuum heat treatment furnace has high thermal efficiency, can complete rapid heating and cooling, can complete no oxidation, no decarburization, no carburization, can remove phosphorus chips on the surface of the workpiece, and has the functions of degreasing and degassing, so as to achieve the effect of surface bright purification . Generally speaking, the workpiece to be processed is slowly heated in the furnace, the internal heat temperature difference is small, the thermal stress is small, and the deformation is small. The product qualification rate is high. It can reduce the cost and has a degassing effect, thereby improving the mechanical performance and service life of the work

Annealing furnace trolley annealing furnace is composed of furnace body (including furnace door), furnace lining, furnace door lifting and sealing device, furnace car, furnace car transmission mechanism, electric heating device, temperature control and recording system. No basic installation is required, and it can be used on a level ground.

(1) Furnace lining:

The furnace lining is made of all-aluminum silicate refractory fiber blanket with good thermal insulation function, and the whole process is uniquely combined with large plates, and the furnace lining is combined.

The furnace body with a large refractory fiber plate structure is selected, which has a good heat insulation function. The weight of the all-fiber furnace lining is only 1/30 of the refractory brick furnace body. It not only has a good heat preservation function, but also saves 30% more energy than the brick resistance furnace of the same specification, and the heating speed is increased.

The all-fiber refractory structure has good thermal shock stability, resistance to rapid cold and heat, and has a longer service life than brick furnaces. This kind of furnace body is very easy to repair. If it is damaged due to mechanical collision, it can be used as long as one-sided repair is performed. This kind of furnace lining also has the characteristics of easy installation and short construction time.

(2) Steel structure: The all-fiber large plate furnace lining is hung on the steel frame, which is welded by section steel, steel plate, etc., which is light and reliable. This furnace uses a full-fiber large-slab structure lining, so its steel structure is much lighter than traditional refractory brick furnaces.
