Dead burned magnesium oxide, refined through calcination at over 1000℃, mainly comprises high-purity magnesium oxide and includes trace impurities such as Al₂O₃, CaO, and SiO₂. Its fine granularity appears in powder form, exhibiting a white or slightly yellow color.
This industrial raw material is not only of exceptional value but also holds a significant position in various fields due to its outstanding performance. Specifically, in the steelmaking industry, dead burned magnesium oxide is indispensable. As a key component of kiln lining, it is extensively used in the form of magnesium oxide sinter, effectively resisting the erosion of high-temperature slag, protecting smelting equipment, and extending its service life. Additionally, during the casting process, ramming agents and molding sands also rely on its excellent performance. For high-temperature applications, precise control of boron content and the Ca/Si ratio further highlights its finesse and professionalism in industrial applications. In fuel oil boilers, the addition of dead burned magnesium oxide can effectively reduce corrosion, ensuring the stable operation of the equipment.
Dead burned magnesium oxide, a high-quality refractory material, plays an indispensable role in the furnaces of steelmaking and cement production due to its high melting point, exceptional thermal stability, and chemical stability. In the intense heat of the steelmaking process, it can effectively resist the erosion of high-temperature slag, protecting the furnace lining and refractory bricks, ensuring the smooth conduct of the smelting process. Meanwhile, in the kilns of cement production, dead burned magnesium oxide serves as a core component of refractory bricks, ensuring the stable operation of the kiln under high temperatures.
Exploring the Secrets of Dead Burned Magnesium Oxide Preparation
The preparation of dead burned magnesium oxide is akin to a precise dance. It requires two key steps: calcination and reburning, each necessitating precise control of temperature and time. Studies have shown that the high-temperature, long-duration calcination process helps form a more stable crystal structure, thereby enhancing the refractory performance of dead burned magnesium oxide.
On the battlefield of steelmaking, dead burned magnesium oxide showcases its unique advantages. Firstly, its high melting point allows it to effortlessly cope with high-temperature environments, reducing damage to the furnace lining and refractory bricks. Secondly, its robust chemical stability enables it to effectively resist the erosion of high-temperature slag, reducing the consumption of refractory materials. Finally, dead burned magnesium oxide's low thermal conductivity means it can reduce heat loss, thereby increasing smelting efficiency.
