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?: The function of furnace shell is beautiful, protective lining, fixed function accessories and so on.

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's the role of anchor bricks in industrial furnaces?: Anchorage brick is a new type of anchor brick relates to an industrial furnace, in particular to anchor brick of an industrial furnace roof, including column hanging end and the anchor structure, opened in the anchor on the surface of the spacing of the grooves in the anchor on at least one surface is arranged along the length direction ribs is provided with ribs, the ribs of the reinforcement and anchorage tension, tensile and flexural strength was obviously improved, the stress generated in the groove at the bar at the barrier can not continue to transfer, so the anchor brick of this kind of structure is not easy to break.

Q: Why does the burner of industrial furnace burn occasionally?: The flameout protection system is made up of burner controller, electromagnetic valve and flame detector, and the flame detection mode is mainly based on the two forms of ultraviolet detection and electrode detection. By utilizing the electric conductivity of the flame, the circuit path of the combustion process generates a weak current, and when the signal amplifier is amplified, the flame is induced to exist, and the small power burner adopts the detection mode more, and is economical and practical.

Q: How many kinds of industrial electric furnaces are there?: This series of electric furnace is made of super light refractory fiber. The electric stove and the temperature control cabinet matching use, the controller may automatically or the manual control electric stove temperature, may press the user request to provide the computer table or the computer control, does the multielement temperature measurement, guarantees the product quality. This series of electric furnaces are periodical operation type electric furnaces.

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: Brief introduction to repair of industrial furnace: Compared with other equipment, industrial furnace repair has many characteristics: more repair times, more maintenance costs, more non-standard equipment and unsafe factors.

Q: What is the difference in structure between industrial furnace and boiler?: Industrial furnace: main heating, steel and other metal materials, or ore and other materials. An industrial furnace of higher temperature, such as forging or heat treatment. Therefore, the energy consumption is large, and the insulation layer is designed to be thicker, and the structure is designed for the final purpose of the production purpose, the product process and the production efficiency.
