Green silicon carbide abrasive is one of the indispensable abrasives in industrial production. Green silicon carbide abrasive uses high-quality silicon stone and petroleum coke as the main raw materials, and then adds table salt as an additive, which is smelted at high temperature in an electric furnace. Silicon carbide micro-powder is green in color, with a crystal structure, high hardness, strong cutting ability, stable chemical properties, and good thermal conductivity. Green silicon carbide micro-powder is a filler and also a good raw material for making non-metallic substances. So what are the characteristics and uses of green silicon carbide abrasive? Let's introduce it to you.
The temperature can generally reach 1760°C under reducing atmosphere.
Green silicon carbide has good thermal shock resistance and can withstand rapid temperature changes to prevent the lining from cracking or breaking.
Due to its high thermal strength, it can be used as a structural material.
It has good wear resistance and can be used as a wear-resistant lining material at a certain temperature.
It can withstand certain slag or hot metal, including the invasion and permeation of alkali metal melt.
It can withstand some furnace gas effects.
Non-ferrous metal smelting
Because green silicon carbide has high thermal stability, good thermal conductivity, is not wetted by non-ferrous metals, has good resistance to corrosion, and has a large thermal conductivity coefficient, it is mainly used as a lining material for high-temperature equipment in non-ferrous metal smelting, such as aluminum electrolysis tank side walls and walls, etc.
Because green silicon carbide has good resistance to slag and iron water and alkali metal corrosion, it is used as an antioxidant. It has good wear resistance and impact resistance at high temperatures, which can improve the life of containers, so it is mainly used as a lining for blast furnace cooling walls, furnace belly bricks, iron water package, torpedo tank, iron groove lining material, and replace silicon iron as a deoxidizer.
Green silicon carbide micro-powder is widely used, which cannot be separated from its characteristics. The silicon material line cutting and grinding special micro-powder used in the production of green silicon carbide micro-powder products utilize good thermal conductivity and thermal stability. It also has high thermal shock stability and load softening temperature, which ensures a small line expansion coefficient during load cutting, thereby ensuring stable cutting. It can also be well adapted to cutting machines. At the same time, green silicon carbide uses its thermal conductivity, heat radiation, and high thermal strength to manufacture thin plate kiln tools, which can not only reduce kiln capacity but also increase the capacity of the kiln and product quality, shorten the production cycle, and is an ideal indirect material for ceramics glaze baking and sintering.
