Application Scope
Online annealing and tempering heat treatment of copper, aluminum and stainless steel non-ferrous metal tube or wire.
Function Structure
Series copper tube annealing equipment adopts AC-DC-AC variable frequency power supply structure. The rectifier of the power supply adopts 3-phase thyristor rectifying. 12-pulse rectifier can be adopted for large power equipment (above 1000kW) to decrease grid side harmonic current. The inverter adopts high voltage large power IGBT module to form inverter power unit, to realize large power output through the superposition of inverter power unit. The inverter realizes impedance matching and electric isolation through matching transformer. The resonant tank circuit adopts serial resonance, which needs independent design for different load heating.
The whole unit of equipment is composed of serial induction heating power supply, resonant tank circuit, circulation soft water cooling system, console (optional), automatic control system (optional).

- Q: Selection of heat preservation material for industrial furnace
- Micro nano heat insulation board.The thermal conductivity of micro nano heat insulation board is very low, only a fraction of the traditional thermal insulation material, and the insulation effect is very efficient.
- 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?
- If the furnace shell temperature is too high, it shows that the lining is not good or damaged, so it should be repaired in time. If you do not repair, take the cooling way, undesirable. Because this will cause a lot of heat loss, resulting in waste of energy, increase production costs, and affect the service life of the furnace.
- Q: What are the combustion equipments used in industrial boilers?
- The boiler is an energy conversion equipment. The energy input to the boiler has the chemical energy and the electric energy in the fuel. The boiler outputs steam with certain heat energy and high temperature water.
- 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: Why does the burner of industrial furnace burn occasionally?
- The basic structure of the complete ignition system is the ignition device and flameout protection device. The ignition burner includes an ignition electrode and an igniter (equipped with some external type transformer, voltage transformer) through the above 10kV, the ignition electrode spark ignition of high voltage discharge to ignite gas column.
- Q: How many kinds of industrial electric furnaces are there?
- Industrial furnace according to the heating mode is divided into two categories: one is the fuel furnace, combustion heat with solid, liquid or gaseous fuel in the furnace for heating the workpiece; the second is in the furnace, the furnace converts electrical energy to heat the heat.
- Q: Brief introduction to repair of industrial furnace
- The working condition of industrial furnace is very bad. It is affected by high temperature, slag erosion and burden wear. Therefore, its working condition changes quickly and its service life is short.
- 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?
- The creation and development of industrial kilns play an important role in the progress of mankind. Chinese appeared more perfect in the Shang Dynasty copper smelting furnace, furnace temperature is up to 1200 DEG C, up to 0.8 meters in diameter kiln stove.
