Oxide Refractory Materials
Oxide refractory materials are made of metal oxides and non-metal oxides as the main components, and use sintering technology to synthesize high-temperature materials. The product is mainly applied in high-temperature device and parts of kiln, furnace, and furnace lining, and it can be used in the fields of heat treatment and metal smelting for a long time under high temperature. The oxides refractory material is widely used in power plants, boilers, blast furnaces and even aviation and space technology.
Introduction of Materials
The oxide refractory material has a wide range of applications in the refractory industry and is widely used to protect the wear and tear of lining in thermal equipment. Generally, magnesium oxide (MgO) is used as a basic material, while other materials, such as alumina (Al2O3), silicon dioxide (SiO2), and zinc oxide (ZnO) are also used. It is usually mixed with a binder to form a paste-like texture and is then placed on the surface of the refractory structure.
Features
The features of oxide refractory materials can be summarized as follows:
1. The oxide refractory material is excellent in thermal shock resistance, which makes it suitable for a variety of high temperature conditions.
2. It has high corrosion resistance and is ideal for use in corrosive environments.
3. It has low thermal expansion coefficient and excellent stability under high temperature changes.
4. It has excellent thermal insulation performance, low density and high compressive strength.
5. It has high resistance to molten metal erosion and high impact toughness.
Uses
Oxide refractory materials are widely used in various furnace linings and other equipment to protect them from the heat of high temperature furnaces. It can be used in metallurgical smelting furnaces such as blast furnaces, soaking furnaces, converter furnaces and so on, as well as in power plants and boilers for heat insulation, or for furnace linings for thermal protective purposes. It is also used in smaller scale applications like glass production, masonry ovens, chemical processing plants, etc., or for heat shields and other protection purposes.
Advantages
The oxide refractory materials have several distinct advantages compared to other types of refractory materials. It can withstand extreme heat over a long period of time and also has excellent thermal shock resistance which makes it ideal for use in applications that require sudden temperature changes. As mentioned above, it has high corrosion resistance, low thermal expansion and excellent thermal insulation, which makes it ideal for those applications where thermal insulation is required. Another advantage of this material is that it has high resistance to the erosion of molten metals and high impact toughness.
Conclusion
Oxide refractory materials are an important part of the refractory industry and are very common in many applications. It is highly resistant to heat and thermal shock, as well as corrosion and erosion. It has excellent thermal properties such as low thermal expansion coefficient, high thermal insulation and thermal shock resistance. These properties make it ideal for use in high temperature furnaces and other heated equipment in various industries, including the power plants and chemical processing.
