Product basic principle and main application:

KJ-V250*400-2000 vertical graphite vacuum furnace is a complete set of equipment for high temperature heat treatment under vacuum (or other atmosphere) conditions.It mainly adopts high temperature resistant alloy and graphite felt as furnace material, graphite plate as heating element, double-layer water-cooled vacuum chamber, which can be configured with circulating water refrigeration system to cool the furnace body.

The equipment is mainly used in high temperature brazing, sintering, tempering, annealing and other heat treatment process.

Furnace details below:

features

Safety and anti-scalding--- The furnace body adopts a double-layer cylindrical horizontal structure to ensure that the furnace wall temperature is lower than 55°C.
Balanced temperature field--- The insulation material inside the furnace is graphite fiber, and the outside of the graphite chamber is 304 stainless steel. The heating element uses high-temperature graphite plate heating, 360 degrees surround.
Intelligent operation---The control system includes touch screen, programmable controller, etc., which realizes power supply, control, recording, monitoring, alarm protection and other functions.
High temperature control accuracy The temperature control accuracy is ±1°C, 16 process curves can be stored, each process group can have 30 sections, and it has PID parameter self-tuning function.
Temperature display is convenient and fast--- The temperature signal is collected by tungsten-nickel thermocouple and optical thermometer. The control cabinet is convenient for operators to observe and record.
Good sealing and insulation---The heating element is easy to repair and replace, and the heating electrode adopts a special vacuum sealing structure to ensure good sealing and insulation with the furnace body.
