Vacuum induction furnace processing technology

Vacuum induction furnace processing technology

Vacuum furnace according to the structure can be divided into vertical and horizontal two series, the series is divided into vertical bell lift and lift the bottom tray. Horizontal series of single structure and front and rear double open the door to open the door again two kinds of structure. Furnace adopt water-cooled wall structures.
Heating equipment to protect the greenhouse adopts full metal type and compound two to choose from, all metal type of heat-resisting stainless steel and molybdenum screen; Compound of heat-resisting stainless steel, molybdenum screen and carbon felt, mullite fiber or silicate fiber composition. The specific choice depends on the user's process conditions and the requirement of process environment.
Heater is nichrome wire (belt), molybdenum wire (belt, bar), several types such as graphite, specific choice depends on the user's maximum temperature. Heater distribution have heating type and all-round heating two all around, to ensure that the user requirements for uniform temperature in the vacuum furnace type.
Cooling system has roots blower external loop structure, centrifugal fan centrifugal fan outside loop structure, cold wall circulate in several types such as the structure, meet the requirements of different cooling speed.
Vacuum system with pump + + mechanical pump, turbomolecular pump, turbomolecular pump, mechanical pump, diffusion pump, roots pump and mechanical pump, roots pump + mechanical pump, low temperature condensate pump + several types such as mechanical pump, according to the ultimate vacuum index selection.
Imported intelligent temperature controller, temperature control can realize the automatic control of heating, constant temperature, cooling function; With process curve storage function, can store several different process curve; Have litre cooling speed is adjustable and accurate clock function, can also according to the actual temperature and set temperature and other parameters; A vacuum furnace operation and power-fail protection function. Has a perfect alarm and protection.
