Refractory materials for different parts of electric ARC furnace(2)Posted by adela li on July 12th, 2017 In order to make balance the damage of the furnace wall and prolong the service life, furnace wall is also used inlaid water cooling box or water cooling measures. The inner surface of the furnace is sprayed with a layer of fire-resistant coating to make the dross form a protective layer, which can reduce the unit consumption of the refractory material. effectively. But the energy consumption is relatively increased. (3) Refractories for bottom of electric ARC furnace The anode end of the direct current electric arc furnace is connected with the contact piece of the furnace bottom, the bottom of furnace use thermal conductivity refractory material or metal components to solve the problem of conduction, the main requirements of the conductive refractory is low resistance (10-4 ~ 10-2 Omega . m) and the resistance must be stable, usually using combination asphalt magnesia carbon bricks with resin ,magnesia-carbon bricks having a carbon content of preferably 10% to 18% are used as the conductive refractory, and include permanent lining, working lining and a protective coating. Working lining use magnesia ramming compound. (4) Refractories for taphole Article source: Refractory materials for different parts of electric ARC furnace(2) Like it? Share it!More by this author |
