In many industrial fields, calcined magnesite sand plays an important role. Understanding its characteristics and applications can help us make more suitable decisions when choosing.
From the perspective of characteristics, calcined magnesite sand has excellent refractory properties. Its melting point is relatively high, and it can maintain stable physical and chemical properties in high-temperature environments, withstanding temperatures above 1600℃, which makes it perform exceptionally well in high-temperature industries. Its thermal expansion coefficient is low, making it less likely to crack due to thermal expansion and contraction during rapid temperature changes, effectively ensuring structural stability during use. In addition, it also has good slag erosion resistance, maintaining its structure and performance when facing various slag erosions, thus extending its service life.
In terms of applications, calcined magnesite sand is widely used in the casting industry. Due to its high refractoriness and good thermal stability, it can be used to make molds and cores, helping to achieve high surface quality and good size precision in castings, meeting the needs of various precision casting. In the metallurgical industry, it is commonly used for lining steelmaking open hearths, electric furnace linings, etc. With its excellent slag resistance, it can effectively resist slag erosion, improve the furnace's service life, and reduce production costs. In the glass industry, as a refractory material for kilns, it can withstand the high temperatures and erosion during the glass melting process, ensuring the continuous and stable production of glass.
When choosing calcined magnesite sand, it is important to consider its characteristics and your own usage scenarios. If used in high-temperature, highly erosive metallurgical environments, attention should be paid to its slag erosion resistance and refractoriness; for precision casting, the thermal expansion coefficient and particle size uniformity are key. Only by fully understanding its characteristics and applications can one select high-quality calcined magnesite sand that meets the needs, allowing it to perform effectively in industrial production.
