Magnesia chrome bricks have high refractoriness, high-temperature strength, strong resistance to alkaline slag corrosion, excellent thermal stability, and certain adaptability to acidic slag. The refractory degree of magnesia-chrome bricks is greater than 2000°C, the load softening temperature is generally above 1550°C, the high-temperature volume stability is good, and the resistance to rapid cooling and heat is stronger than that of magnesia bricks. Unburned magnesia chrome brick is a new type of high-temperature refractory material. It not only has excellent fire resistance but also has good environmental protection and economy. It has been widely used in modern steelmaking, cement, glass, and other industrial fields. RS refractory brick manufacturer provides high-quality unburned magnesia chrome bricks.
Unburned magnesia chrome brick is a high-temperature refractory brick material that is thermoformed by a special manufacturing process from magnesia, chromium raw materials, alumina powder, silica powder, etc. This material does not need to undergo traditional processing processes such as carbonization and calcination, so it is also called a non-fired manufacturing technology. Unfired magnesia-chromium brick is a new structural material, which is composed of magnesia-chromium spinel phase and phase-poor zone. It has high compressive strength and thermal shock resistance, as well as excellent chemical stability and wear and corrosion resistance. It is a very excellent high-temperature refractory material.
Composition and Manufacturing Process of Unburned Magnesia Chrome Bricks
The main ingredients of unburned magnesia chrome bricks include magnesium and chromium raw materials, alumina powder, silica powder, etc. Through a special manufacturing process, these materials are mixed together, pressed, and thermoformed at high temperatures. The result is an unburned magnesia chrome brick with good high-temperature resistance.
Traditional processing methods require raw materials to be carbonized, calcined, and other processes. The non-fired manufacturing technology can eliminate these links and reduce production costs. At the same time, it also greatly reduces the impact on the environment and has good environmental protection.
Performance Characteristics of Unburned Magnesia Chrome Bricks
High-temperature stability. Unfired magnesia chrome bricks have high thermal stability and thermal shock resistance and can operate stably for a long time in high-temperature environments. It has important application value for high-temperature production equipment in steel, cement, glass, and other industrial fields.
Chemical stability. Unburned magnesia chrome bricks also have good chemical stability and can withstand corrosion from a variety of acids, alkalis, and salts. Able to work normally in acid and alkali environments.
High mechanical strength. Unfired magnesia chrome bricks have high compressive strength and tensile strength and can withstand a large amount of pressure and tension. It also has high wear resistance and corrosion resistance.
Lightweight and high strength. The density of unburned magnesia chrome bricks is relatively light, and it also has high mechanical strength and chemical stability. Therefore, the weight of the equipment can be greatly reduced and the energy consumption in the industrial production process can be reduced.
Economical and environmentally friendly. The manufacturing process of unburned magnesia chrome bricks does not require traditional processing methods such as calcination. Therefore, relatively less energy is consumed. At the same time, it can also reduce the emission and treatment costs of waste gas and wastewater, which is very economical and environmentally friendly.
Application Range of Unburned Magnesia Chrome Bricks
Due to its excellent performance characteristics, unburned magnesia chrome bricks have been widely used in steel, cement, glass, and other industrial fields. Specifically, it mainly involves the following areas.
Steel smelting industry. Unfired magnesia chromium bricks can be used in high-temperature equipment in all aspects of steel smelting. Such as various coke ovens, converters, electric arc furnaces, etc.
cement industry. Unfired magnesia chrome bricks can be used in high-temperature equipment such as cement kilns, rotary kilns, and hot blast furnaces. Has high use value.
glass industry. Unfired magnesia chrome bricks can be used in production equipment such as glass kilns. Has good heat resistance and chemical stability.
Petrochemical industry. Unfired magnesia chrome bricks can be used in various high-temperature equipment in the petrochemical industry. Such as high-pressure steam boilers, other chemical reactors, etc.
In short, unburned magnesia chrome bricks have become an indispensable high-temperature refractory material in modern industrial production due to their excellent performance characteristics and wide range of applications. At the same time, it also has the characteristics of economic and environmental protection, which helps to promote the common progress of industrial development and environmental protection.
Magnesia-chrome bricks are the most commonly used refractory bricks in copper smelting thermal kilns. In top-blown converters, horizontal converters, anode furnaces, flash furnaces, and electric furnaces. In common copper smelting thermal kilns such as Kifset furnaces, Ausmet furnaces, reverberatory furnaces, oxygen-rich bottom-blown furnaces, etc., magnesia-chromium bricks are the main configuration.
