Mainly used for atmosphere sintering, vacuum heat treatment, high temperature vacuum sintering, suitable for stainless steel based, hard alloy, super alloy, high specific gravity alloy, cermet, magnetic material and high melting point metal and other carbides, borides and other intermetallic compounds and Sintering of oxides. 

This series adopts horizontal (or vertical) water-cooled sleeve structure. According to the temperature of the furnace and the customer's process requirements, nickel-chromium electrothermal alloy or graphite or molybdenum or tungsten is used as heating element and heat shield. Other insulation materials can also be used. A composite heat shield composed of. The heating element can be divided into multiple zones, each zone is independently temperature controlled, and programmable PID adjustment. The furnace can be removed as a whole for easy maintenance. The furnace is provided with heat-resistant stainless steel and equipped with an inflator. The furnace can be filled with protective gas or working gas, and the inflation flow can be adjusted. Equipped with in-furnace or extra-furnace circulation cooling device to accelerate the cooling of materials in the furnace, shorten the work cycle and improve work efficiency. 
Note: 1 The rated load is 75% of the working area volume, and the density of the charging material is 4kg/L. 
2 The following parameters are the parameters in the standard configuration and can be adjusted according to customer requirements. 
3 According to the needs of customers, upgrade the configuration. 
3.1 can be equipped with built-in or external quick cooling system. 
3.2 can be equipped with PLC programmable controller and human-machine interface control system. 
3.3 According to the requirements of vacuum degree, the oil diffusion pump can be added, and the ultimate vacuum can reach 10-3Pa. 
3.4 For multi-zone temperature control, the FP21 programmable regulator is used as the main meter (with SR80 series), and the PID regulator is used as the secondary meter to form the temperature control system. 
3.5 The heating element and heat shield with special materials are selected, and the sintering temperature can reach above 2500 °C.
