Graphite parts are increasingly widely used in vacuum furnaces. They are not only used for heating elements and heat shields for vacuum furnaces, but also for structural parts, such as brackets, trays, guide rails, bolts, bearings, fan blades, etc. The application of graphite in vacuum furnaces greatly simplifies the design and manufacture of vacuum furnaces, reduces the consumption of metals such as tungsten, molybdenum, tantalum, stainless steel, etc., reduces costs, improves certain properties of vacuum furnaces, and expands application field of vacuum furnaces.

Graphite is with good vacuum performance, thermal conductivity, low thermal expansion coefficient, increased strength with increasing temperature, good processing technology, etc., coupled with low cost, so it is a high-quality and low-cost material.

● Application Of Graphite Products

1. Used as refractory material: Graphite and its products have the properties of high temperature resistance and high strength. It is mainly used in the metallurgical industry to make graphite crucibles. In steel making, graphite is often used as a protective agent for steel ingots and as an inner lining of metallurgical furnaces.

2. As a conductive material: Used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, positive electrodes of mercury rectifiers, graphite washers, telephone parts, coatings for television picture tubes, etc.

3. Used as a lubricating material: Graphite is often used as a lubricant in the machinery industry. Lubricating oil often cannot be used under high-speed, high-temperature, and high-pressure conditions, while graphite materials can work at high sliding speeds at a temperature of 200 to 2000 ℃ without lubricating oil. Many equipment that transports corrosive media widely use graphite materials to make piston cups, seals and bearings, and they do not need to add lubricating oil during operation.

4. Graphite is with good chemical stability. Processed graphite, which has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, is widely used in the production of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, Pump equipment. It is widely used in petrochemical industry, hydrometallurgy, acid-base production, synthetic fiber, papermaking and other industrial sectors, which can save a lot of metal materials.
