China wholesale Graphite Block - Graphite Crucible – Hexi

Hexi carbon mainly produces graphite electrodes. Besides graphite electrodes, we also produce some graphite products. The manufacturing process of these graphite products has the same process and quality inspection as graphite electrodes. Our graphite products mainly include graphite crucible, graphite cube, graphite rod and carbon rod, etc. Customers can customize graphite products with different shapes according to their needs. The production process of graphite products is to mix petroleum coke with asphalt. Then, carbon atoms are graphitized by pressing, baking and roasting at a high temperature of 3000℃. And then processed into different shapes according to market demand.

Graphite crucible produced by Hexi carbon has good thermal conductivity, high temperature resistance, corrosion resistance, low thermal expansion coefficient and good chemical stability. In the use process, even if the temperature is very high, it can still maintain good performance; The sudden change of cold and hot temperature has little influence on crucible performance. Graphite crucible has good performance in smelting alloys, nonferrous metals and other alloys, so it is widely used in metallurgy, casting, machinery, chemical industry and other industries. The graphite crucible produced by Hexi Carbon Factory has a good effect both in technology and in use. We can process graphite crucibles with diameters ranging from 300 mm to 800 mm, and can also customize them according to customer requirements. The quality of graphite products provided by our company will be checked before leaving the factory. If there are any problems, we promise to solve them within 5 working days.

Use of electrodes

When the electrode is used, it should be dried by the electric furnace in advance, the temperature should not exceed 150 ℃ and the time should not be less than 24 hours.
