Mainly used for tool steel, die steel, high speed steel, high strength steel, titanium and other materials after vacuum quenching vacuum tempering (vacuum aging)
VTF Vacuum Tempering Furnace
The furnace temperature control system uses an advanced intelligent temperature controller with advanced intelligent PID control algorithms and five large LCD displays. With perfect self-correction, adaptive function, temperature control and furnace temperature display, it can be programmed and controlled according to the process requirements of the workpiece, automatically adjust and control the heating power in the furnace, easy to operate, and support the control system also has sound and light. Over-temperature alarm and other functions. The purpose of vacuum tempering is to maintain the advantages of vacuum quenching of the material (the product is not oxidized, does not decarburize, contains no carbon, has a bright surface, no corrosive pollution, etc.). Well type tempering furnace is an energy-saving circulating tempering furnace for tempering of general metal parts in air, quenching, annealing and aging heat treatment of aluminum alloy die castings, pistons, aluminum plates, etc.

VTF Vacuum Tempering Furnace
Product Features and Special Configuration
Completely eliminates the oxidation and decarburization of the bow and arrow surface during heating, and obtains a clean surface without a metamorphic layer. For those who only grind one side during sharpening (such as the decarburization of the groove surface after the twist drill is ground) The exposure between the layers is exposed to the cutting edge)
Easy to operate, manual/automatic free switching, fully automatic control, fully avoiding human error during work
The temperature measurement and control precision are obviously improved, and the thermocouple is ±1.5 °C. However, the temperature difference between different parts of the workpiece in the furnace is large. If the lean gas is used for forced circulation, the throw can be controlled within the temperature range of ±5 °C.
With a comprehensive alarm system, it can effectively protect equipment
Gas quenching pressure can be adjusted according to different materials, saving costHigh degree of mechatronics, based on the improvement of temperature measurement and control accuracy, workpiece movement, air pressure adjustment, power adjustment, etc. can be pre-programmed, and quenching and tempering are carried out according to the steps.
This equipment is available in both horizontal and vertical versions. For long-rod workpieces and overweight workpieces, vertical bottom-loading vacuum quenching furnaces can be used to achieve vacuum quenching, solid solution, aging, brazing, etc. for oversized, overweight, and ultra-long workpieces.
No pollution to the environment, no need to carry out three waste treatment
High degree of mechatronics, based on the improvement of temperature measurement and control accuracy, workpiece movement, air pressure adjustment, power adjustment, etc. can be pre-programmed, and quenching and tempering are carried out according to the steps.
Users can choose graphite heaters or metal heaters according to the actual situation of the company. 6bar or 10bar cooling pressure can also be selected depending on the properties of the material being processed
