As a high-quality refractory material, magnesium olive sand has a wide range of applications in the foundry industry, among which 3-6-purpose magnesium olive sand is favored because of its unique properties.
The 3-6 mesh magnesium olive sand has a moderate particle size, which can not only provide good filling, but also ensure the clarity of the casting. It has a high refractoriness, generally up to about 1710 ℃, can effectively resist the oxidation erosion in high temperature environment, so as to protect the casting from damage. In addition, the expansion coefficient of magnesium olive sand is small, and the expansion is slow and uniform at all temperatures, which helps to reduce the sand inclusion defects caused by thermal stress in the casting and improve the quality of the casting.
In terms of chemical composition, the 3-6-size magnesium oxide (MgO) is rich in magnesium oxide (MgO), the content is usually more than 44%, and contains the right amount of silicon dioxide (SiO2) and other trace elements, which together give the magnesium olive sand excellent fire resistance and corrosion resistance.
In summary, 3-6 mesh magnesium olive sand, with its moderate particle size, high refractoriness, low expansion coefficient and excellent chemical composition, plays an irreplaceable role in the foundry industry and is one of the important materials for manufacturing high-quality castings.
