OEM Manufacturer Graphite Electrode Uhp 700mm T3l - graphite electrode tools – MORKIN Detail:
Product Introduction
Carbon electrode paste is a conductive material for ferroalloy furnace, calcium carbide furnace and other electric furnace equipment. The electrode paste has the characteristics of high temperature resistance and low coefficient of thermal expansion. It has a relatively small resistance coefficient, which can reduce the loss of electric energy. With small porosity, the heated electrode can be oxidized slowly. With high mechanical strength, the electrode will not break due to the influence of mechanical and electrical load.
Ferroalloy smelting is carried out through the arc generated in the furnace by the current input from the electrode. The electrode plays a very important role in the whole electric furnace. Without it, the electric furnace cannot work.
Raw Material of Electrode Paste
Electric calcined anthracite, calcined petroleum, graphite scrap as the raw material, coal asphalt and coal tar as the binder.
Application
1.For silicon manganese smelting in Submerged arc furnace
2.For ferrosilicon smelting in Submerged arc furnace
3.For ferrochrome smelting in Submerged arc furnace
4.For calcium carbide smelting in furnace
5.For ferronickel smelting in Submerged arc furnace
Production Process of Carbon Electrode Paste
Crushing of raw materials (ECA, petroleum coke, graphite powder, etc.) – Grinding – Screening – Batching – Kneading (put melted medium temperature asphalt into the dry raw materials) – Forming – Finished Products
