LIHUA IGBT induction heaters adopt the latest MOSFET, IGBT power units and frequency conversion control techniques with high efficiency, low energy consumption and higher output power. With constant current and constant power control function to greatly optimize the heating process of metals, realize efficient and fast heating, and fully exert the superiority of the products. Power consumption is half of traditional electron tube high frequency induction heating equipments under the same conditions. With 100% load design, can work for continuous 24-hour a day. Infrared temperature detector can be equipped to realize the automatic control of temperature, improve heating quality and simplify manual operation. With heating-insulating-cooling three stages function setting, the heating and insulating time required can be get to accommodate to the batch and repeated heating situations. With multiple status display of overflow, over voltage, low water, phase failure and load malfunction, providing higher reliability and sustainability. Select power supply according to the power and frequency. The higher the frequency, the shallower the heating depth, and the lower the frequency, the better the diathermancy.

Quenching machine tool
Mainly by the quenching machine, medium frequency power supply ( high frequency power, ultrasonic frequency power source, ultra-high frequency power ), cooling device of three parts; wherein the high frequency quenching machine consists of a machine body, upper and lower loading and clamping mechanism, a clamping and rotating mechanism, the quenching transformer and resonant tank, cooling system, quenching liquid circulation system, electrical control system, quenching the machine is generally a single-station ( small diameter workpiece can be used when the double-station quenching machine ); quenching machine from the structure with vertical and horizontal two categories, users can choose according to quenching quenching machine tool, for special parts or special technology, according to the heating requirements of design and manufacture of special quenching machine tool. Use by quenching machine tool and medium frequency power supply ( high frequency power, ultrasonic frequency power source, ultra-high frequency power), achieved by PLC program control of induction hardening process, commonly
used in gear, bearing, shaft parts, valve, cylinder and all kinds of mechanical parts quenching and heat treatment.
Common quenching device type
The outer circle quenching series: on all types of shaft, rod, tube, the circular parts ( such as bearings, valves etc.)
the outer circle surface of whole or partial quenching.
Inner circle quenching series: various types of pipes, mechanical parts of the inner circle for the whole or partial
quenching, such as cylinder, shaft sleeve.
Terminal (End), surface quenching series: on the mechanical parts of the face, flat part of whole or partial quenching.
The special-shaped parts quenching series: for special-shaped parts of the surface of a whole or partial quenching.
Large parts quenching series: large volume,heavy especially big parts of the whole or partial quenching, such as marinegear, dam sluice rail, large oil pipeline etc..
Die quenching series: mould surface induction quenching machine tool is applicable to a large automobile panel die and largenon-circular space curved surface parts of the heat treatment of the numericalcontrol technology and equipment
