The function of silicon carbide castable
Silicon carbide castable, also known as SiC castable. It is a type of non-shape refractory material made from carborundum powder and other materials. It serves several functions in various applications:
1. Resistance to high temperatures: Silicon carbide castable has excellent thermal stability and can withstand high temperatures. It works in environments where temperatures reach extreme levels, such as furnaces, kilns, and incinerators.
2. Abrasion resistance: Silicon carbide castable has high hardness and good abrasion resistance. This property makes it suitable for applications that involve abrasive materials or high wear conditions. Such as cyclone linings, pipeline linings, and baffle plates.
3. Chemical resistance: Silicon carbide castable has good chemical stability and resistance to chemical attack. It can withstand exposure to corrosive gases and liquids, making it suitable for use in chemical reactors, flue gas desulfurization systems, and other chemical processing equipment.
4. Thermal shock resistance: Silicon carbide castable has good resistance to thermal shock, meaning it can withstand rapid changes in temperature without cracking or spalling. This property makes it suitable for applications where rapid temperature variations occur, such as in the metal industry, where molten metal is poured into molds.
5. Insulation properties: Silicon carbide castable can possess good thermal insulation properties, which is useful for applications that require both high-temperature resistance and insulation. It helps to conserve energy and improve the efficiency of heating equipment.
Silicon carbide refractory materials have high high-temperature performance. And the applications of carborundum castable include:
1. Steel smelting, refractory bricks made of silicon carbide castables and aggregates. Those firebricks are suitable for lining steel drums, nozzles, plugs, blast furnace bottoms and boshes, tapping slots, converter and electric furnace tapping holes, and water-cooled slide rails for heating furnaces.
2. Furnaces of non-ferrous metals (zinc, copper, aluminum, etc.). It is widely used in distillers, distillation tower trays, electrolytic cell sidewalls, molten metal pipelines, suction pumps, and melting metal crucibles.
3. Silicate industry. It is widely used as a roof and flame barrier material for various kilns, such as muffle furnace lining and sagger.
4. In the chemical industry. There are more than oil and gas generators, organic waste calciners, petroleum gasifiers, and desulfurization furnaces.
5. Aerospace industry. It works as rocket nozzles and high-temperature gas turbine blades in space technology.
