How to Choose High-Quality Calcined Magnesite Olivine Sand In industries such as metallurgy and casting, calcined magnesite olivine sand is an important refractory material, and its quality directly affects production efficiency and product quality. So, how can one select high-quality calcined magnesite olivine sand? Purity is the primary consideration. High-purity calcined magnesite olivine sand has fewer impurities and better refractory performance. In high-temperature environments, impurities may trigger chemical reactions, reducing the material's stability and service life. One can check the product's inspection report to clarify the content ratio of major components such as magnesium oxide (MgO) and silicon dioxide (SiO₂). Generally, a magnesium oxide content of 40% - 50% and a silicon dioxide content of around 35% - 45%, with low levels of other impurities, are ideal. Particle size distribution should not be overlooked. Different application scenarios have different requirements for particle size. For example, in precision casting, products with uniform particle size and a higher proportion of fine particles are needed, as this can make the mold surface smoother and reduce casting defects. In some applications requiring high strength, such as large metallurgical furnace linings, an appropriate ratio of coarse particles can enhance the structural strength of the material. Therefore, it is essential to choose magnesite olivine sand with a particle size distribution that matches actual usage needs. Additionally, the degree of calcination is crucial. Fully calcined magnesite olivine sand has a stable crystal structure, offering better volume stability and slag erosion resistance. One can initially judge by observing the product's appearance and color; products with uniform color and dense texture are usually well-calcined. It is also advisable to consult suppliers to understand their calcination processes and temperature control. When selecting calcined magnesite olivine sand, a comprehensive assessment of purity, particle size distribution, and calcination degree, combined with one's actual production needs, is necessary to choose a suitable product that aids in efficient and stable production, enhancing product quality and economic benefits for the enterprise.
