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

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.: Heat treatment furnace is mainly for the mechanical processing and casting industry workpiece annealing, quenching, carburizing, quenching and tempering, heat treatment equipment.

Q: What are the companies in the world that are currently engaged in metallurgical furnaces?: Basically, no industrial furnace manufacturer can do all types of stoves.Often associated with the industry is very large,so your ranking is basically meaningless.

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's the role of anchor bricks in industrial furnaces?: These layers need to be joined and anchored. Anchor brick is this role. The heat insulation layer at the horizontal section of the flue is mostly a narrow cavity.

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: What are the advantages of a vacuum furnace?: The accuracy of furnace temperature measurement and monitoring is obviously improved. The indicating temperature of the thermocouple and the temperature of the furnace reach 1.5 C. But there is a large temperature difference in a large number of workpieces in different parts of the furnace. If the forced circulation of the rarefied gas is adopted, the temperature range of the temperature range of + 5 DEG C can still be controlled.

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?: 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: 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.
