Product Description
Graphite Products for High-temperature Furnace
Products: various kinds of heating elements, heating chamber, hearth, heating tube, bracket, joint board, graphite adjusting plate, joint part, graphite tie-in of conducting rod, graphite heater, graphite insulated chamber, graphite tray, graphite box for sintering, graphite plate,heater tube, bridge frame, connection parts, electrode joint, insulation barrel and heat shield for heating system etc. We are able to design and fabricate the special U-shaped, W-shaped and screw-shaped heating tube or heating equipment. Serving complex design,Installation,technique for special high temperature furnace and industrial furnace include vacuum furnace, pressure furnace, carbide furnace and intermediate frequency furnace.
Speciality of Raw Material: high density, high temperature resistance, good oxidation resistance and thermal shock resistance, good performance of electrical conductivity, high mechanical strength. Mainly used in various thermal treating element and heating like vacuum furnace production. It also has the ability of heat conduction or heat insulation.
The special graphite heating components which are used in the high temperature furnace with temperature reached 2200 degree at vacuum environment and 3000 degree in the deoxidize and insert gas environment. It has uniformity of heating structure, good electrical conductivity and high electrical load, corrosion resistance, high purity and mechanical strength. The advantage is energy efficient, high value, low maintenance cost. Graphite heating elements/components are used frequently in high-temperature furnaces, such as vacuum sintering furnaces, graphitization furnaces, vacuum brazing furnaces, intermediate frequency vacuum induction furnaces, high temperature heat treatment furnaces, etc.The graphite heater is the core part of the high-temperature vacuum sintering furnace, and its quality directly affects the performance and operating cost of the high-temperature vacuum sintering furnace. The design of the thermal field of graphite heating element is varied, which specific design choice is mainly based on the specific analysis of the process flow. The graphite heating element of most high-temperature vacuum sintering furnaces includes four main components: heaters and their connecting parts, heat insulation parts (or reflection screens), thermal field supporting parts, and workpiece carrying hearth. These accessories often need to be replaced regularly due to material problems or time problems.Vibration Graphite |
