Primary Advantages of Pit Carburizing Furnace

· The patent technologies we own including the unique corrugated muffle and the air tube, the top air guide cover with spherical head, the open type anti-carburizing furnace cover and insulation blankets, to reduce the thermal stress deformation, cracking of the structural elements in the furnace under the high temperature.

· The full fiber furnace lining is used to improve the thermal efficiency of the equipment.

· Using the master, joint control and monitor the furnace temperature control system to ensure that the carburizing temperature control accuracy.

· Double set parallel carbon potential control system and multi-element carbon potential control mode, PID simulation quantity regulating and control of carbon potential, simulation design of carburizing technology and online expert system of dynamic control are used to achieve the precise carbon potential control and dynamic control of carburizing technologies.

· The use of variable import the Integration program controller, set the temperature control, carbon potential control, mechanical and electrical motion control, safety interlock as a whole, with fail alarm records, self-diagnostics to ensure high reliability of equipment operation.

· The host computer system can edit all kinds of technical process, design carburizing process, control technical process, save technical process, measure data, alarm, consult history technical process and so on. The computer system combines receiving, sending and control instruction of integrating changeable controller together.

Main Advantages of Pit-Type Quenching Tank

●Multi-set mixers with variable frequency speed regulation, draft tube and guide shell, high efficiency quenching medium mixing system, the driving effect at the side of uniform distribution of cold media after circulating heat exchange are used to achieve whirled uniform flow of quenching medium, which improve the uniformity of media temperature and reduce the quenching deformation of the workpiece.

●High-power cooling heat exchanging unit of quenching circulation and temperature control system of quenching medium have been equipped in order to ensure the normal thermal exchange in the process of quenching.

●Two circulating pump are furnished, which can be switched automatically to ensure the safety and reliability of the operation of quenching process.

●Thermal exchange system including cooling and heating of quenching medium, can be equipped as inner and outer circulation system. The system can automatically run according to the temperature and operational order of quenching medium.

●The choice of a variety of quenching medium: oil, water, water-based, salt bath and so on.

Structural Features of Cleaning Machines

●Used pantent technology of TLON.the single-chamber cleaning machine with high efficiency and low energy consumption is integrated with hot alkaline solution and water cleaning system, separation system of oil and water, as well as drying system. The cleaning and technological process of workpieces are controlled mechanically and fully automated.

●The power of heating hot cleaning liquid takes only 25 ~ 30% of that of common cleaning machine.

●Operation of equipment used to automate hum an-machine interface and PLC control.

●Taking small volume and small area.

Main Advantages of Pit Tempering Furnaces

●Special suspended corrugated air tube, top air guide covered with spherical head, and strong airflow circulating fan are used to reduce the distortion of structural parts in the furnaces, increase the service life, and improve the uniformity of furnace temperature.
