Products Description
The main difference between neutral and acid lining materials for induction furnaces is their chemical composition and physical properties.
Products Specifications
Neutral lining materials usually refer to materials that are not acidic or alkaline in chemical composition such as oxides or carbides. Neutral ramming material has a higher melting point and better electrical conductivity, and is suitable for use in high-temperature melting processes in induction furnaces. Common neutral lining materials include aluminum oxide, silicon carbide, zirconia, etc.
Acidic lining materials usually refer to chemical components with strong acidity, such as silica, ferric oxide, etc. Acidic lining materials easily produce acidic oxides at high temperatures, which react with alkaline oxides in the furnace to form molten glass material, which is beneficial to adsorbing and fixing metal oxides, thereby achieving the purpose of smelting and refining.
In the operation of induction furnaces, neutral lining materials are mainly used for high-temperature melting and protecting the melt surface, while acidic lining materials are used to reduce the alkalinity of the slag and improve the refining degree of the metal.
