Introduction:
Chromite refractories, also known as chrome-containing refractories, are a group of refractory materials that contain chromite (chromium oxide) as a key component. These refractories are widely used in high-temperature applications, particularly in the steelmaking and non-ferrous metal industries.
Chromite refractories primarily consist of chromite, along with other additives and bonding agents to achieve desired properties. The chromium content in these refractories typically ranges from 8% to 40%, depending on the specific application.
Chromite refractories exhibit excellent resistance to high temperatures, allowing them to withstand extreme heat conditions encountered in various industrial processes. They can maintain their integrity and structural stability at temperatures exceeding 1800°C.
Chromite refractories have good resistance to chemical corrosion, making them suitable for environments containing acidic or basic compounds. They can withstand the corrosive effects of molten metals, slags, and aggressive chemical substances encountered in metallurgical operations.
