Product Introduction of High Precision Box Furnace
use:

High-precision box furnace is a standard precision box furnace that implements the military standard for aviation industry. It is mainly used for precision heat treatment in aviation, aerospace, military industry, national research institutes, high-precision manufacturing, etc., and is widely used in international aviation manufacturing. The product implements the military standard GJB5-9-88 of the Ministry of Industry of China. Sintering experiment of special steel, precision alloy strip, wire, special steel casting, forging, metal, non-metal powder pressed parts.

Structure introduction:

Furnace body and lining: The structure of this high-precision high-temperature box furnace is similar to that of a standard box furnace. The shell is welded by steel plates and sections. The lining material is made of ultra-lightweight 0.6g / cm3 energy-saving refractory bricks. The alumina fiber cotton is used for thermal insulation, and the expansion insulation powder is filled between the furnace shell and the furnace lining aluminum silicate sandwich for thermal insulation.

Heating element: The electric heating element is made of high alloy products 0Cr27Al7Mo2. It is placed on the bricks on the two walls of the furnace and the bottom of the furnace.

Power and safety: The lifting of the furnace door is carried out by the electric motor, the worm gear reducer and the transmission of the sprocket chain, and it is braked by the electromagnetic brake. The upper part of the furnace door has a circuit breaker. When the furnace door is opened, the power of the high-temperature box furnace is cut off to ensure the safety of the operator.

Temperature control system: There are three thermocouple holes on the top of the furnace. When in use, the thermocouple is inserted into the furnace. The temperature of the box furnace is controlled by a temperature control cabinet. In order to improve the uniformity of the furnace temperature, the high-precision box furnace adopts three-zone heating, and the heating elements are arranged according to the uniform temperature cloth wire method. The box furnace keeps the uniform temperature of the three zones in the process of heating and holding. The box furnace is equipped with a microcomputer three-zone program automatic temperature control cabinet. Three microcomputers are used for high-precision automatic temperature control and furnace door operation control of the three-zone heating. The furnace temperature is mainly controlled and recorded automatically.
