Heating and heat preservation rooms are available in full metal and composite types. All metal types are made of heat-resistant stainless steel and molybdenum screens. Composites are made of heat-resistant 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 requirements of the process environment.
Vacuum furnace heaters are nickel-chrome wire (belt), molybdenum wire (belt, rod), graphite and other types, the specific choice depends on the user's requirements of the highest temperature. Heater distribution has four types of heating and omnidirectional heating to ensure the user's requirements for uniform temperature in the furnace.
The cooling system has several types of Roots blower external circulation structure, centrifugal fan external circulation structure, cold wall centrifugal fan internal circulation structure, etc. to meet different cooling rate requirements.
Vacuum system includes ion pump, turbo pump, mechanical pump, turbo pump, mechanical pump, diffusion pump, Roots pump, mechanical pump, Roots pump, mechanical pump, cryogenic condensate pump, mechanical pump, etc. Ultimate vacuum index selection.
Vacuum furnace temperature control adopts imported intelligent temperature controller, which can realize automatic control function of heating, constant temperature, and temperature reduction; has storage function of process curve, can store multiple different technological curves; has adjustable and accurate temperature and speed, and clock function, Can display the actual temperature and set temperature and other parameters at the same time; with PID parameters from the operation and power-down protection.
With perfect alarm and protection measures.
Equipped with imported multi-point recorder, it can record the vacuum, pressure, temperature and other technological curves of the entire process, which is convenient for process analysis, quality control and production management.
The vacuum gauge can use high-reliability imported digital intelligent vacuum gauge or domestic high-quality vacuum gauge to ensure the vacuum degree and temperature control chain to meet the technological requirements.
The entire process control adopts the imported programmable logic controller (PLC) to complete, and all the actions adopt chain protection. There are two working modes: manual and automatic. The user can select the manual operation mode, or select the way of the industrial control group to control multiple units. .

Commonly, Hard ferrite is a type of ceramic Fe2O3,BaCO3 or SrCo3 compund material.The density of ferrite magnets about 5g/cm3, and they are divided to hard ferrite and soft ferrite.
They are both electrically nonconductive and ferrimagnetic.Of course,they also can as Construction Magnet. Hard ferrites have higher coercivity and higher remanence after magnetization. Ceramic magnets are cheap and widely used in household appliance such as refrigerator horseshoeshaped magnet, letric motors, teleconmmunication loud speaker,magnetic recording.etc.
Soft Ferrite Magnet is a sort of Fe2O4,Zinc or Nickel compund material.They have a low coercivity thus called soft ferrites. Because of their comparatively low losses at high frequencies.
They are extensively used in the cores of RF tranformers and inductor in applications of AM redios.
