Refractory

Chrome-Magnesite

Refractory products made from a mixture of chromite (40–50 percent or higher) and roastedmagnesite. The refractoriness of such products is about 2000°C and higher, depending on the purityof the raw material. Both roasted and nonroasted chrome-magnesite refractories are produced withdifferent binders, for example, refractories reinforced with metal plates. They are used in cement-roasting furnaces and in ferrous and nonferrous metallurgical plants. In addition to chrome-magnesite refractories, chrome-magnesite powder-like products are also made, which are used inthe production of ramming refractories to line furnaces and in guniting.
