40-70 mesh magnesium olive sand for casting is a high-quality refractory material, which is widely used in the casting industry. The following is a detailed introduction to it:
Forsterite has a chemical formula of Mg2SiO4 and belongs to the forsterite category among silicate minerals. Its particle size range is between 40-70 mesh, which makes it very suitable as a foundry sand. The material has excellent fire resistance, the fire resistance can reach 1910 ℃ (in some cases may reach 1720 ℃), and can withstand various pressures in high temperature environments.
During the casting process, magnesium olive sand exhibits excellent thermal stability and thermal expansion properties. Its thermal expansion is smaller than silica sand, and the expansion is uniform, not easy to produce sand phenomenon. This feature makes the casting surface smooth, clear outline and accurate size, which greatly improves the qualification rate of castings.
In addition, magnesium olive sand also has good resistance to metal oxide erosion, especially for high manganese steel castings have high chemical stability. It can effectively prevent the chemical and mechanical sand sticking of the castings and ensure the quality of the castings.
In addition to the above advantages, magnesium olive sand also provides a good working environment for producers because of its free silica, no silica dust hazard, and no CO gas generation during pouring.
In summary, 40-70 mesh foundry magnesium olive sand has become an indispensable material in the foundry industry due to its excellent fire resistance, thermal stability, erosion resistance and environmental protection characteristics. Whether it is the production of manganese steel parts or other alloy steel castings, magnesium olive sand can provide excellent performance and reliable protection.
