The use of sodium silicate in melting metals is extensive due to the high resistance of this compound to temperature and high adhesion strength. These properties have made silicate sodium an integral part of melting metals or the foundry industry. The widespread use of sodium silicate in melting metals has led us to pay more attention to this issue in the Iranian Scientific Journal of Silicate. If you work in the foundry industry and you want to produce metals in the shortest time and at the lowest cost; This is for you.
The reason for the use of sodium silicate in melting metals
The history of the use of sodium silicate in melting metals dates back to the 1930s. Silicate sodium was originally used as an adhesive in the foundry industry, but over time, in the 1960s, the use of CO2 alongside silicate sodium became popular. This method can be considered a great revolution in the casting and smelting industry of cast iron, non-metallic and steel.
In the metal casting industry, especially steel casting, large amounts of silicate sodium are used. The most important reasons for the use of sodium silicate in melting metals are the following
Silicate sodium is used in melting metals as a fire resistant and polishing metal appearance.
In the classic CO2 process, the molds are made of sand and silicate sodium used as the adhesive.
Chemical reactions between CO2 and silicate sodium cause the initial hardening of the sand-sodium silicate mixture. The mixture loses its moisture, the bonds become a solid mass.
Molds made by this process can be used immediately and do not need to be baked, as they form a hard shell at medium temperatures and provide sufficient porosity to release hot gases.
Silicate sodium are compatible with the starches and dextrins used in the preparation of foundry materials and replace expensive vegetable oils and resins used to form certain types of molds.
Another use of sodium silicate in melting metals is as a defloqulant or lubricant. This property reduces the viscosity thus preventing the metal molten material from clotting.
Conclusion
A large part of the use of sodium silicate in melting metals is as a reliable coating for casting molds. The word safe is used because silicate sodium prevents the burning of special metal melting molds. Considering the wide use of sodium silicate in melting metals, it can be said that the quality and purity of this compound also has a great role in the strength of the casting mold.
