Small Scale Synthesis Of Silicon Carbide

The raw materials used for synthesizing silicon carbide are mainly vein quartz or quartz sand with SiO2 as the main component and petroleum coke with C as the main component. Low grade silicon carb...

ESK Method For Sic Production

In 1973, the German ESK company improved the Acheson method and developed the ESK method. The large-scale SiC smelting furnace of Esk method is built outdoors, without end walls and side walls, lin...

Acheson Method For Sic Prduction

The shape of the traditional Acheson resistance furnace is like a rectangular trough, which is a hearth made of refractory bricks. Two sets of electrodes penetrate into the furnace bed through the ...

Purpose Of Calcination

The purpose of calcination is to remove the moisture and volatile matter in the petroleum coke, to fully shrink the volume of the carbon raw material, and to improve its thermal stability and physi...

Reasons For Graphite Floating Phenomenon in Ductile Iron Process

(1) Carbon equivalent: The carbon equivalent is too high, so that a large amount of graphite is precipitated in the molten iron at high temperature. Since the density of graphite is smaller than th...

What Are The Material Properties Of Silicon Carbide

Because of its 3.2g/cm3 specific gravity and high sublimation temperature (approximately 2700 °C), silicon carbide is very suitable as a raw material for bearings or high-temperature furnaces. It w...

Silicon Carbide Development Background And Trend

In recent years, with the increase of the country's requirements for the atmospheric environment, it has become a consensus to strictly limit the pollution emissions of industrial enterprises, ...

Method Of Adding Recarburizer

The stirring of molten iron can promote recarburization. Therefore, compared with the power frequency induction furnace with strong stirring power, the medium frequency induction electric furnace w...

Selection Of Equipment And Raw Materials in Ductile Iron Process
