The Use of Graphite Electrodes on Industrial Silicon Furnaces

图片
The industrial silicon reduction electric furnace is a resistant electric arc furnace. The graphite electrode  is inserted into the furnace charge for submerged arc smelting, continuous heating, intermittent silicon production, continuous operation, also called submerged arc furnace. Graphite Electrodes on Industrial Silicon Furnaces Uses of Industrial Silicon Industrial silicon is also called crystalline silicon or metallic silicon. The main use of industrial silicon is as an additive for non-ferrous alloys. When silicon is added to some non-ferrous metals, it can significantly improve the strength and hardness of the metal. It can also improve the casting performance and welding performance of the substrate. Industrial silicon is also used as an alloying agent for silicon steel with strict requirements, deoxidizer for smelting steel, silicone resin, silicone rubber, etc. After a series of process treatments, industrial silicon can be made into monocrystalline silicon and polycry...

Types of Fused Zirconia Corundum Bricks and Their Main Applications

图片
As the saying goes,  the insider knows the ropes, while the outsider just comes along for the ride.  It is believed that people who frequently contact or use fused zirconia corundum bricks can easily distinguish their models. But for those who are not familiar with fused zirconia corundum bricks, this may be slightly more difficult. Refractory manufacturers will take everyone to understand the model classification of fused zirconia corundum bricks and explain in detail the specific use parts. High-Quality AZS Blocks Structural characteristics of fused zirconia corundum bricks Fused zirconia corundum brick is a white solid formed by using pure alumina powder and zircon sand containing 65% zirconia and 34% silica after being melted in an electric furnace and injected into the mold to cool. The lithofacies structure is composed of the eutectoid of corundum and zirconite and the glass phase. In terms of phase science, it is the eutectoid of the corundum phase and zirconite phase,...

The Main Components and Applications of Acid-Resistant Castables

图片
Acid-resistant castable refers to a refractory castable that can resist corrosion by acidic media at a temperature of 800 to 1200°C. It is mainly prepared by using water glass as a binder, acidic or semi-acidic refractory materials as aggregate and powder, and a small amount of coagulant. The disadvantage of this castable is that it cannot be used where there is an alkaline corrosive medium. Next, let's learn more about the main components of acid-resistant castables and their applications. Acid-Resistant Castable The main components of acid-resistant castables The main components of acid-resistant castables are water glass , hardening accelerators, acid-resistant refractory aggregates, and powders. Acid-resistant refractory aggregates and powders mainly include particles such as silica, cast stone, wax stone, diabase, and fine powders of acid-resistant materials such as waste silica bricks, silica, waste porcelain, and cast stone. Water glass is generally used as a bonding agent....
