3、 Equipment composition: ThisHigh vacuum box type atmosphere furnaceIt mainly consists of furnace body (including lining), electric heating device, vacuum device (mechanical pump+diffusion pump+bellows+vacuum valve+digital vacuum gauge+vacuum gauge+inlet and outlet valves+vacuum pipeline), instrument temperature control system, cooling system, two-way proton flow mixing system and other main parts.

4、 Equipment Overview:

4.1 Furnace body:

4.1.1 Furnace size: 500 * 500 * 400 (mm)

Furnace body dimensions: according to the drawing requirements (length x width x height)

4.1.2 Shell

The shell structure is an outer frame structure, which is assembled and welded from carbon steel. This structure has the advantages of being firm, reliable, aesthetically pleasing, and not easily deformed during long-term high-temperature use.

4.2 Furnace lining:

The furnace lining is made using our company's all fiber specialized technology, achieving excellent heat storage effect. Moreover, this product is easy and fast to construct, and can be directly fixed on the inner layer of the furnace shell. This structure of furnace wall is sturdy and durable, with good energy-saving effect, light weight, and can reduce transportation difficulty. Compared with other products, the advantages are low thermal conductivity, low heat capacity, excellent corrosion resistance, excellent thermal stability, thermal shock resistance, and thermal insulation.

4.3 Electric heating device:

4.3.1 The electric heating element is a high-quality resistance wire, which has good oxidation resistance, high temperature resistance, and high load resistance, ensuring long-term use.

4.4: Instrument temperature control system:

4.4.1 Temperature control system:

This furnace is equipped with a new type of furnace temperature automatic control system, which uses Yudian intelligent programmable instruments for temperature control. It can set the heating rate, insulation temperature, and insulation accuracy according to the set process curve, achieve automatic adjustment and control of heating slope and insulation time, and display theoretical and measured values, improving the control level and temperature control accuracy. This control method adapts the supplied heat to the heat absorption of the workpiece, making it more reasonable and saving energy. The temperature control system also has an over temperature alarm and power-off function.

4.5 Vacuum device:

Mechanical pump+diffusion pump+bellows+vacuum valve+digital vacuum gauge+vacuum gauge+inlet and outlet valves+vacuum pipeline.

4.6 Atmosphere system: Two proton flow mixed gas system

4.7 Cooling water system: including one set of refrigeration cycle unit
