Embodiment Construction

[0007] 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...

Abstract

An energy-saving heating furnace includes a furnace body, a furnace cover, a strip-like 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 from fire-refractory bricks. The strip-like electric heater is fixed on an inner wall of the furnace wall. The furnace wall and the furnace cover are both produced from aluminum silicate fibers. The energy-saving heating furnace is low in heat conductive coefficient, is less in heat accumulation, is high in temperature increasing speed, is good in integrality, is free of seam joints, is good in heat preservation effects, is less in heat dissipation loss, can save resources (reducing more than 30% of energy consumption), can effectively prevent heat dissipation of heat from interior to exterior of the furnace, can reduce heat loss and can prolong 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 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] The object o...
