Silicon Carbide

silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond .Mechanical intensity of it is higher than fused alumina. It is britte and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc.It is also broadly used as refractory material and metallurgical additive.

Furnace Drying Tamp Mass

Introduction

Furnace drying tamp mass is prepared through selection of high grade synthetic raw materials, additive and binder. According to particle close packing theory. It is characterized by strong penetration resistance to molten steel, corrosion resistance, easy sintering, high packing density and easy installation. It is an ideal material for electric furnace bottom.

Silicon Carbide Refractories

Silicon Carbide Refractories

 

     articles produced from silicon carbide (carborundum) and additives, containing between 20-35 and 70-98 percent SiC.
     Silicon carbide refractories are classified, according to the method of bonding the silicon carbide granules, as siliceous (formed in the oxidation of carbide), nitride (Si3N4), oxynitride (Si2ON2), and aluminosilicate, as well as recrystallized and self-bonded. The products are formed on presses (or by other methods) from powdered mixtures containing silicon carbide and subsequently fired at 1300°-1550°C (certain types at 2000°-2200°C).
     Silicon carbide refractories exhibit high thermal conductivity: 7-17 watts per (m.°K) at 800°C. As a result, they show good thermal stability. They are also resistant to deformation at elevated temperatures. At 130O°-1500°C in an oxidizing medium they undergo gradual oxidation, particularly in the presence of an excess of oxygen and of water vapor. Silicon carbide refractories are used in recuperators, retort furnaces, nonferrous-metal-lurgy plant units, shelves of tunnel wagons (in firing porcelain and ceramics), and boilers.
