graphite electrode for refining furnace
The graphite electrode sector continues to weaken
National Technology fell nearly 6%, and Huajin, Lomon Baili, and Yichengxin were able to follow the decline.
CGM ultra-high power graphite electrode physical indicators
Ultra-high power graphite electrode (English abbreviation UHP) graphite electrode uses high-quality petroleum coke, needle coke, pitch coke and other raw materials, after calcination, medium crushing, screening, batching, kneading, pressing, roasting, high pressure impregnation, graphitization , CNC machining and other processes are refined, with compact and uniform structure, good electrical conductivity, good thermal conductivity, high mechanical strength, and strong oxidation and corrosion resistance at high temperatures. It is widely used in electric arc furnaces and submerged arc furnaces to smelt various alloy steels, yellow phosphorus, Industrial silicon, brown corundum and other alloys and non-metallic materials are an important part of the contemporary raw material industry.
The following is the product physical index of CGM new material ultra high power graphite electrode: CGM carbon ultra high power graphite electrode index (UHP) nominal diameter ultra high power graphite electrode allowable current load (A) current density (A/—— –24 Electrode length, diameter and allowable deviation Nominal diameter Actual diameter (mm) Length (mm) Maximum allowable deviation Max minimum Min minimum length of black skin short length
