Artificial Grate Electrode is made of high-quality low-ash materials,such as needle coke,petroleum coke and coal pitch.After the process of calcining,burdening,kneading,forming,baking,high-pressure impregnation,gratization and then high-precision CNC machining. The fin ished products are with characteristics of low resistivity,exce lent electric conductivity,low ash,fine inner structure,good anti-oxidation and high mechanical strength,it is the very best conductive material for arc furnace and smelting furnace. Grate electrodes are packed with wooden cages and nipplesare packed with wooden boxes.Grate electrodes and nipples can be packed together according to the requirementsfrom customers.The products are protected by waterproof and dustproof plastic sheets inside and fixed by steel bands,durable for road,railway and sea transportation.
