I. Core Material: Double-Layer 304 Stainless Steel
-
Main Material:Our high-temperature graphitization furnaces primarily usenational standard 304 stainless steelfor the furnace shell and main structural components.
-
Reason for Selection:304 stainless steel offers excellent corrosion resistance, good high-temperature strength, and mature processing technology. It effectively copes with the workshop environment and ensures long-term structural stability.
-
Special Design:The furnace body features adouble-layer water-cooled structure. Cooling water channels are designed between the two layers of stainless steel plates. After water cooling, the surface temperature of the furnace shell can be maintained within a safe range while effectively protecting the furnace shell from deformation.
-
II. Sealing Technology: Fluororubber O-Rings
-
Sealing Components:The equipment widely usesfluororubber (FKM) O-ringsfor dynamic seals (such as furnace doors) and static sealing points.
-
Performance Advantages:Compared to ordinary rubber, fluororubber has excellent high-temperature resistance (long-term service temperature from -20°C to above +200°C), outstanding vacuum performance, and resistance to most chemicals (such as oils, solvents). It is an ideal choice for sealing vacuum and pressure equipment.
-
Installation Position:All sealing rings are installed onwater-cooled metal flanges, ensuring they operate in a suitable temperature environment,延缓 aging, and ensuring long-term sealing effectiveness.
III. Comprehensive Value
This combination of"stainless steel skeleton + fluororubber seals"provides a solid physical guarantee for the equipment to operate stably under long-term repeated thermal stress cycles and slight positive pressure/vacuum conditions.
