Information
Spinel ramming mass manufacturers tell you that magnesia-aluminum spinel refers to magnesia and alumina as raw materials, which are actually quite common in life. It is mainly a synthetic spinel refractory raw material.
Spinel ramming mass manufacturers tell you that magnesium aluminum spinel has good corrosion resistance, wear resistance and thermal shock stability. Its main uses are as follows: First, magnesia-aluminum spinel bricks are used in cement rotary kilns to replace magnesia-chromium sand, which not only avoids the pollution of chromium, but also has good anti-stripping performance; second, it is used to make ladle castables, which is very Greatly improves the corrosion resistance of the steel lining. Therefore, it is widely used in steel-making refractories. Spinel ramming mass manufacturers tell you that the production of amorphous high-purity refractory raw materials is the preparation of high-quality pre-synthesized spinel to provide new raw materials.
There are two methods of magnesia-aluminum spinel: electrofusion and sintering. Spinel ramming mass manufacturers tell you that the electrofusion method is composed of industrial alumina or high-purity bauxite and light-burned magnesia, including natural or seawater (brine) water-based magnesia, mixed in proportion, and melted at about 2200 ° C in an arc in the furnace. Spinel ramming mass manufacturers tell you that the sintering method is to grind, mix and granulate the above raw materials, and calcine them in a rotary kiln or shaft kiln above 1800 °C. Some bricks are made of industrial alumina or high-purity bauxite clinker. , adding or mixed grinding, mixing and forming according to the ratio requirements, and then firing magnesia-alumina spinel bricks at high temperature, mainly used for open hearth furnace tops and other parts.
