China High Temperature Uniform Pre-Vacuum Tempering Pit Furnace

Application Range:
ZRJ3 series Pit type Vacuum tempering furnace are commonly used for a tempering of heat treating applications including those requiring inert atmospheres, the tempering of austenitized and quench hardened steel.
It mainly used in aerospace, aviation, aircraft manufacturing industry for precision parts with light non-oxidation tempering heat treatment.
And for precision machinery manufacturing of precision parts non-oxidation and non-decarburization heating, quenching, annealing, tempering heat treatment and spheroidizing annealing in Automobile manufacturing industry.
Our vacuum tempering furnace are provided for temperature ranges from 150ºC to 700ºC.
Product Features:
ZRJ3 series Pre-Vacuum Tempering Pit Furnace use our patented technology.
Recirculating blower provides high velocity vertical down air flow for excellent heat transfer.Vertical down air flow specifically designed for tempering, uniform temperature distribution in furnace chamber.
Using special high-precision temperature control system, heat treatment technology curve to achieve full automation.While the automatic execution of precision heat treatment process, to achieve rapid heating insulation and efficient energy-saving heat treatment of advanced technology.
Structure description:
The pre-vacuum tempering furnace is mainly composed of pit type furnace shell coiled with steel and furnace body made by welding section steel.
The furnace lining adopts the energy-saving composite fiber or full-fiber, which have remarkable effect on energy and power saving.The electric heating element use the high temperature resistance alloy element, which can last up to 5 years.
The furnace pot is made of imported high temperature stainless steel sheet.
The furnace cover is insulated with stainless steel, and the Vacuum seal stainless steel fan is installed to keep the air pressure stable and the temperature even.
The vacuum furnace panel is equipped with a vacuum interface, a protective atmosphere interface and a vacuum pressure gauge.
Controller system:
The Pre-vacuum furnace is divided into multi-zone temperature control, multiple microcomputer program control, automatically displaying the measured temperature, calculating the temperature ramp rate and the set value with overtemperature alarm and automatically process curve records.
The temperature control precision of which is 1 ºC.
