Product Description:

 

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).

 

Technical Features

Ø Perfect structure design

1.Integration design of switchgear rectifying cabinet and inverter output cabinet, with compact structure and small size.

2.Power combination of the inverter bridge is accomplished by the way of power unit superposition, which is convenient for installation and repair. Each IGBT power unit is designed to be 200kW. Inverter output adopts matching transformer to realize electric isolation of power supply and load with high security and reliability of power supply.

3.Multi-section of inductors adopt serial connection with high voltage and small current. The whole heating efficiency is higher than parallel power supply.

4.Resonant tank circuit mode is an independent design as per users actual requirement with convenient and flexible site layout.

5.High standard electromagnetism compatibility design, electromagnetism radiation meets national standard. Closed cabinet design, meeting rigor environmental requirements on site.


Ø Full digital control system

1.3-phase rectifier adopts high cost performance MCU controlling to realize precise synchronism trigger with high control precision and small grid-side non characteristic harmonic.

2. Resonant inverter adopts CPLD to form full-digital control system that is characterized by their automatic constant angle, high phase-lock precise and wide scope of phase-lock.

3. Adopt inverter side PSM power adjustment technology with strong load adaptability and easy impedance matching. The grid side power coefficient≥0.92 and harmonic content is the relatively lowest.

4. The power supply has perfect protection function with reliable working and low failure rate.


Ø HMI and fault diagnosis system (optional)

1.Adopt PLC and touch screen to form perfect HMI system.

2.Realize integrated automatic control of power supply system.

3.Fault display and diagnosis system.

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.
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:How to use industrial furnace equipment?
When the furnace is used, the lifting mechanism of the furnace door must be in good condition, and the wire breakage of the steel wire is not allowed to exceed the designated value. The weight should be properly allocated, and the drive department shall be provided with a protective cover.
Q:What is an industrial furnace pit?
In twentieth Century 50s, coreless induction furnaces were developed rapidly. Later, electron beam kilns, using electron beams to impact solid fuels, strengthen the surface to heat and fuse materials with high melting point.
Q:What are the companies in the world that are currently engaged in metallurgical furnaces?
There are many kinds of furnaces in metallurgical industry,colored and black,smelting and heat treatment are also included.
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 industrial furnace masonry?
Before masonry construction, the pre process and parts that may affect the quality of masonry work shall be re tested,masonry construction shall be carried out according to the datum central line and the datum elevation.
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: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.
The general metal die casting plant and the metal smelting plant need process melting and dissolving furnace, usually there are reverberatory furnace, cupola, rotary furnace, etc. I do the melting furnace of aluminium alloy.
