Product Description:

Application Scope

Quenching heat treatment of metal workpiece.

Function Structure

Complete set of quenching equipment is mainly composed of quenching machine tool, quenching power supply (medium frequency power supply, high frequency power supply, super-audio frequency power supply) and cooling equipment. The quenching machine tool is composed of machine tool bed, upper and lower clamping mechanism, clamping and rotating mechanism, cooling system, quenching liquid circulation system and electric control system. Customer can select quenching machine tool as per quenching technics. For special workpiece or technics, the quenching machine tool can be designed and manufactured according to heating technics requirement.


      Quenching power supply generally selects parallel induction heating power supply. In order to stabilize quenching frequency to adapt multiple workpiece specifications, tank circuit of quenching power supply need to select quenching transformer.

Technical Features

Ø  Perfect structure design

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

2.The power supply selects DC chopper mode to ensure the grid side power coefficient≥0.92 and a relative lower harmonic content.

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

4.The shape of quenching inductor is decided by workpiece and quenching technics, and the inductor is well-made.

 Ø   control system

1. PLC program control or CNC numerical control is optional.

2. AC full digital servo control, numerical control system adopts every advanced control circuits to reduce position tracking error to minimum, and compensate nonlinear error of static/kinetic friction of mechanism system automatically.

3. Quenching machine tool and power supply has perfect protection function with reliable working and low failure rate.

   * Can be customized according to user’s requirement.


* equipment selection

Ø  penetration heatingA kind of heating method that heat treatment layer is less than current thermal penetration depth, and with suitable specific power density.

Workpiece surface superheat is small, with thin thermal transition layer and high heating efficiency (quenching efficiency is 30~40%)

Q:Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.
The main equipments of heat treatment are classified into two major categories: main equipment and auxiliary equipment. The main equipment includes heat treatment furnace, heating device, surface modification, surface oxidation device, surface mechanical enhancement device, cooling equipment, cold processing equipment, process parameter detection and control instrument; auxiliary equipment includes cleaning cleaning equipment, furnace atmosphere heating medium permeability meter preparation equipment, cooling device, quenching medium heavy transport machinery, quality testing equipment, power transmission line and auxiliary equipment, fire safety equipment, dust and other production fixture.
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: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 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 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:Why does the burner of industrial furnace burn occasionally?
The general process for burner ignition, blowing furnace, electric spark ignition, solenoid valve, open the gas in case of delayed spark ignition, detection device detects the flame, the controller accepts signal so that the solenoid valve open, gas continuous normal combustion. However, if the ignition fails or the burner fires, the detector cannot detect the flame, which causes the solenoid valve to close and the burner flameout.
Q:How many kinds of industrial electric furnaces are there?
Electric furnace is divided into four categories: resistance furnace, induction furnace, arc furnace and special electric furnace according to the different ways of electric heating.
Q:What are the combustion equipments used in industrial boilers?
The main auxiliary equipments of the general boiler are: upper coal machine, ash blower, blower, draught fan, economizer, feed pump and water treatment unit. Oil boilers are: oil pumps, burners, tanks and so on.
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:How to use industrial furnace equipment?
If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.
