Application Scope
The welding of steel tube, stainless steel tube, aluminum tube, copper tube, H-beam and special section tube.
Function Structure
Solid state high frequency welder is mainly applied to high frequency straight seam tube mill line. The high frequency power supply adopts AC-DC-AC frequency-variable structure. The rectifier adopts 3-phase 6-pulse thyristor rectifying, IGBT DC chopping or 3-phase 12-pulse thyristor rectifying. Inverter adopts high voltage large power MOSFET to form full bridge resonant inverter. Inverter output adopts high efficiency ferrite matching transformer to accomplish power synthesis, impedance matching and electric isolation. Resonant tank circuit adopts secondary side series resonance.
The whole set equipment is composed of switchgear rectifying cabinet, inverter output cabinet, circulation soft water cooling system, console and positioning table.
Technical Features
Perfect structure design
1. Independent design of switchgear rectifying cabinet and inverter output cabinet, connected by soft cable, which is convenient for layout at user’s site.
2.Rectifier selects DC chopping to ensure grid side power coefficient≥0.92 and harmonic content is the relative lowest. Adopt 12-pulse thyristor rectifying to eliminate grid side fifth and seventh harmonic, and grid side harmonic current is the lowest.
3.Power combination of the inverter bridge is accomplished by the way of power unit superposition. Each MOSFET power unit is designed to be 50kW/100kW/150kW and slideway drawer structure, which is convenient for installation and repair.
4.High standard electromagnetism compatibility design, electromagnetism radiation meets national standard.
5.High standard electromagnetism compatibility design, electromagnetism radiation meets national standard.
All-digital control system
1.3-D 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.The welder has electronic automatic load matching function with good load adaptability, high electrical efficiency and high power coefficient.
4.The welder has perfect protection function with reliable working and low failure rate.
HMI and fault diagnosis system
1.Adopt PLC and touch screen to form perfect HMI system.
2.Realize integrated automatic control of welder system.
3.Fault display and diagnosis system

- 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: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.
- 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: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: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: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.
- 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 industrial furnace masonry?
- Pre construction and recording shall be carried out on complex and important parts of industrial furnaces,masonry of all kinds of masonry shall be made with staggered joint masonry.
- 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: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.
