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?: Industrial kilns and industrial furnaces are collectively referred to as industrial furnaces. Industrial furnaces mainly refer to devices that heat materials by combustion reactions.

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: What are the companies in the world that are currently engaged in metallurgical furnaces?: Each manufacturer has its own industry and technological advantages.If you say that the performance rankings, turnover, and so on, it seems that no one has done this ranking.

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: How many kinds of industrial electric furnaces are there?: Electric furnace is divided into four categories: resistance furnace, induction furnace, arc furnace and special electric furnace according to the different ways of electric heating.

Q: What are the advantages of a vacuum furnace?: No pollution to the environment, no need for three wastes treatment.

Q: How to use industrial furnace equipment?: If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.

Q: What is the difference in structure between industrial furnace and boiler?: From the way: industrial furnace (electricity, natural gas, gas, induction heating is considered electricity), boilers (coal, all kinds of hot exhaust gas, a variety of gas, seemingly less electricity).

Q: What is an industrial furnace pit?: Later, a chamber kiln with a semi closed or fully enclosed kiln made of refractory bricks can be used as fuel for coal, gas or oil, and electricity can be used as heat source. The workpiece will be heated in the kiln hearth.
