Embodiment 1

[0014] An energy-saving heat treatment well-type heating furnace includes a furnace body 1, a furnace cover 3, a strip electric heater 4, an electric fan 5 and a furnace cover moving mechanism. Furnace body 1 is composed of aluminum silicate fiber furnace wall 6 and furnace bottom 2 made of refractory bricks. The furnace cover 3 is an aluminum silicate fiber furnace cover, and the furnace cover 3 is buckled on the upper port of the aluminum silicate fiber furnace wall. The strip electric heater 4 is a known electric heater, fixed on the aluminum silicate fiber furnace wall 6 on the inner wall. The electric fan 5 is arranged below the furnace cover 3 , and the fan rotating shaft passes through the furnace cover 3 and is connected with the output shaft of the motor 8 , and the motor 8 is fixed on the furnace cover 3 . The furnace cover moving mechanism includes a furnace cover support plate 9 , a vertical shaft 10 , a first support wall shaft seat 11 and a second support wall s...

Embodiment 2

[0016] Embodiment two is basically the same as embodiment one in structure, and its difference is:

[0017] The furnace body 1 is fixedly arranged in a furnace shell 7 made of steel, and the outer wall of the furnace cover 3 is fixed with a furnace cover shell 13 .

Abstract

The invention provides an energy-saving heat treatment well type heating furnace which comprises a furnace body, a furnace cover, a belt-shaped electric heater, an electric fan and a furnace cover moving mechanism. The furnace body is composed of a furnace wall and a furnace bottom, the furnace bottom is built by refractory bricks, the belt-shaped electric heater is fixed on the inner wall of the furnace wall, and both the furnace wall and the furnace cover are made from alumina silicate fibers. The furnace body is fixedly arranged in a furnace outer shell body made of metal, and a furnace cover outer shell body is fixed on the outer wall of the furnace cover. The using average temperature of the furnace wall and the furnace cover made from the alumina silicate fibers is 980 DEG C, the average degree of fire resistance is 1,100 DEG C, the volume density is within 2.52 to 2.53g / cm3, a heating wire is shrunk lower than 110 DEG C and is within 1.96 to 2.02% in 24 hours, the breaking strength is 0.03MPa, and the heat conduction coefficient is 0.094w / m.k. The energy-saving heat treatment well type heating furnace has the advantages of low heat conduction coefficient, less heat accumulation, quick temperature rising, good integrity, no seams, good heat-preservation effect, less radiating losses, energy saving and the like (more than 30% energy consumption can be saved). Moreover, the heating furnace not only can effectively prevent the internal temperature of the furnace from spreading to the outside of an electric furnace, but also can reduce heat losses and prolong the service life of the furnace body.

Description

technical field [0001] The invention relates to a heating furnace for metal heat treatment, in particular to a well-type heat treatment furnace with a furnace body and a furnace cover made of aluminum silicate fibers. Background technique [0002] Heat treatment pit heating furnace is an indispensable heating equipment in metal heat treatment. The body of furnaces of heating furnaces such as carburizing furnaces, soaking furnaces, annealing furnaces, and hot blast stoves that have been used at present are all composed of a furnace shell and a refractory brick lining arranged in the furnace shell, and the furnace cover is a metal furnace cover. The disadvantage of this heating furnace is that the heating rate is slow, the heat preservation performance is poor, and energy is wasted. In addition, there are also problems such as long manufacturing cycle, many consumables, high manufacturing cost, and short service life of the furnace body. Contents of the invention [0003] ...
