Product Description

China Supply of Graphite Electrode Carbon Graphite Electrodes UHP/HP/RP Dia 300mm with Nipple

 

Graphite electrodes deliver unrivaled high-temperature performance, with a sublimation temperature of 3650–3697°C, enabling stable operation above 2500°C—far exceeding metal electrodes' heat resistance limits. Their ultra-low thermal expansion coefficient (just 1/40 of steel) grants excellent thermal shock resistance, preventing cracking during rapid temperature swings in smelting or frequent equipment startups. Premium needle coke raw materials optimize their crystal structure, boosting stability and service life in ultra-high-power applications. In electric arc furnace steelmaking, they maintain structural integrity at 3000°C arc temperatures, while in silicon pulling furnaces, they ensure precise temperature control, elevating crystal yield. This reliability minimizes downtime, enhances production continuity, and delivers long-term value for metallurgical and high-temperature industrial processes.

Our main product is graphite electrode are manufactured with high quality raw materials including petroleum cokes,needle cokes and coal tar pith through the production process ofcalcining,crushing,screening,dosing,kneading,extruding,baking,impregnation,machining,
our products are characteried by superior compact structure.
