Application Scope

The power supply provides energy for the zone melting furnace of preparing high purity single crystal. It is the HF induction heating power supply with power supply technology on the input side to provide stable power output for zone melting furnace. It is with the merits of small volume, high power factor and low loss.

Product Principle

The power supply is composed of the power control cabinet and vacuum tube oscillatory power cabinet. In power control part, it adopts special thyristor power control unit, which is combined with advanced DSP and PLC control technology makes the power supply be with merits of high control accuracy and reliability. High power tube, as the core component of vacuum tube oscillatory power cabinet provides stable power output for zone melting furnace.

Technical Features:

1. HMI: It adopts Siemens PLC + touch screen and is designed of full Chinese menu display. It works with simple parameter setting, and has a dual protection with double passwords to prevent wrong operation of parameters setting.

2. Advanced DSP control technology: The power unit control part adopts advanced digital processing technology. It works with merits of fast regulating speed and high control precision to ensure the zone melting furnace power control requirements during production.

Q: Selection of heat preservation material for industrial furnace: Ceramic fiber blanket can be used.Ceramic fiber blanket color white, regular size, set fire, heat insulation, insulation in one. Free from any binding agent.

Q: What is the difference between industrial furnaces and boilers?: A boiler is a mechanical device for heating water into hot water or steam by the use of heat from fuel or other sources of energy. The original meaning of a pot is a water container heated by fire. The furnace is the place where the fuel is burned. The boiler includes two parts, the cooker and the furnace.

Q: Should the industrial furnace shell cool down?: Normally, the furnace shell temperature of an industrial furnace is below 50 degrees, so there is no need to cool down.

Q: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.: Heat treatment furnace is mainly for the mechanical processing and casting industry workpiece annealing, quenching, carburizing, quenching and tempering, heat treatment equipment.

Q: What are the companies in the world that are currently engaged in metallurgical furnaces?: Basically, no industrial furnace manufacturer can do all types of stoves.Often associated with the industry is very large,so your ranking is basically meaningless.

Q: What are the combustion equipments used in industrial boilers?: Main auxiliary equipment for general boilers:1. domestic appliances 2. civilian gas boiler 3. industrial gas furnace.

Q: What's the role of anchor bricks in industrial furnaces?: The wall of an industrial furnace or flue is mainly composed of an inner lining layer, a heat insulating layer and an outer wall layer. The lining is a refractory brick, and the outer wall is an ordinary sintered brick.

Q: What are the advantages of a vacuum furnace?: The utility model can completely eliminate the oxidation and decarburization of the workpiece surface in the heating process, and can obtain clean surfaces without deterioration layers. For cutting tools that grind only one side of grinding (such as twist grinding, the surface of the groove surface is exposed to the blade directly), the cutting performance is greatly improved.

Q: What is the difference between industrial furnace masonry and ordinary masonry?: Of course, the difference is like the difference between a hog cap and a 100 story building. See the industrial furnace manual.

Q: What is the difference in structure between industrial furnace and boiler?: At the same time, the working environment is relatively poor, the structure should be sturdy and durable, the transfer mechanism (generally) to stable and durable low failure rate, the insulation layer must be thick enough and the economy, the steel structure housing materials used to be enough.
