Good Quality Large Vacuum Carburizing Furnace - Horizontal double chambers carbonitriding and oil quenching furnace – Paijin Detail:

Description

Application

The vacuum double-chambers low-pressure carbonitriding oil quenching furnace has various functions including carburizing, carbonitriding, oil quenching and pressure air-cooling. Is mainly used for quenching, annealing, tempering the die steel, stainless steel, high-speed steel, high-alloy steel tools; and carburizing, carbonitriding quenching the medium or low-carbon alloy steel. It can used for one-time carburizing, pulse carburizing and other carburizing and cabonitriding processes.

Characteristic

1.High intelligent and efficient. It is equipped special developed vacuum low-pressure carburizing simulation software.
2.Good temperature uniformity. heating elements are evenly arranged 360 degrees around the heating chamber.
3.No carbon black pollution. The heating chamber adopts the external insulation structure to prevent the pollution of the carbon black in carburizing process.
4.Good cooling uniformity and speed,less workpiece deformation. Its quenching stir device driven by frequency conversion and with guiding device.
5.Its functions including:Thermostatic oil quenching, Isothermal quenching, convective heating, vacuum partial pressure.
6.Frequency conversion stirring quenching, channeling quenching, pressure quenching.
7.Good carburized layer thickness uniformity, Carburizing gas nozzles are evenly arranged around the heating chamber, and the thickness of carburized layer is uniform.
8.Smart and easy for process programming, stable and reliable mechanical action
9.Automatically, semi-automatically or manually alarming and displaying the faults.
