Product Detail

Product Tags

The graphite electrode produced by Hebei Hexi Carbon Company is 250mm in diameter and 1800mm in length. It is calcined, crushed, screened, mixed, kneaded, formed, baked, impregnated and graphitized with high-quality petroleum coke, needle coke and coal pitch, and then machined according to customer requirements.

HP250 graphite electrode produced by Hexi Carbon Company has the characteristics of low resistivity, good electrical conductivity, excellent thermal shock resistance, low ash content, compact structure, good oxidation resistance, high mechanical strength, and is the best conductive material for electric arc furnace and smelting furnace.

All types of graphite electrodes produced by our factory can be machined according to customer requirements. The factory has a large number of RP,HP,UHP graphite electrode blanks. After receiving customer’s order size requirements, processing and packaging can be completed within ten days and sent to Tianjin Port.

Welcome new and old customers to contact us to consult technical questions, consulting prices.

Honest and professional, we can be trusted.
