Fired Chrome – Magnesite (CHM)
Refractory products made from a mixture of chromite (40-50 percent and higher) and dead burned magnesia. The refractoriness of such products is about 1850°C and higher depending on the purity of the raw material. They are used in cement roasting furnaces and in ferrous and nonferrous metallurgical plants. In addition to bricks, chrome-magnesa products are also made, which are used in the production of Ramming Refractories to line furnaces and in guniting as well.
Advantages
- High Refractoriness
- High Temperature Strength
- Strong Basic Slag Erosion Resistance
- Good Thermal Shock Resistance
- Strong Acidic Slag Erosion Resistence
