Various types of silicon carbide bricks are available in the market, which are used for application in metallurgical, building construction and chemical industries. These silicon carbide bricks are available in different forms, such as bonded alumina bricks, Sialon bonded alumina bricks, high chrome bricks and high density zirconia bricks.
Several studies have been conducted on high chrome bricks. They show that a high chrome brick has a remarkable structure. It has high temperature strength, excellent wear resistance, and acid corrosion resistance. The material is also characterized by its low thermal conductivity. It is suitable for use in various types of furnaces. Among them, it is mostly used in chemical industry furnaces.
The main raw material of a high chrome brick is zircon sand. Zircon sand has good thermal shock stability, high mechanical strength, and high refractoriness under load. It is widely used in alkali-free glass furnaces. The structure of zircon is compact, so it has good chemical stability. It can be used in a glass kiln, a non-ferrous metal smelting furnace, and a pure steel furnace.
In addition, the oblique zircon crystals are the backbone of the brick body. The high density and high creep resistance of zircon make it suitable for use in the back lining of a borosilicate glass furnace.
Compared to conventionally prepared MgO-C bricks, the newly developed MgO-C brick was evaluated to see if it could outperform the conventional brick in several key areas. The new MgO-C brick showed improved thermal shock resistance and mechanical properties. The brick was also subjected to several tests to determine its application in the Aluminum Industry.
The best part about this research is that the results were published in a high impact journal. The research investigated the various phases present in the MgO-C brick and the resulting properties. The findings include phase formation as a function of temperature and temperature-dependent properties of the MgO-C bricks. The new MgO-C bricks showed improved mechanical properties in comparison with conventionally prepared MgO-C (12%) bricks.
The study also investigated the Young's modulus of elasticity of the brick. This was a bit more difficult to determine, but a proposed measurement method was used to get the correct result. The new MgO-C brick was evaluated in comparison with the conventionally prepared MgO-C (12%) and its physical properties were measured at room temperature and 850degC for 72 hours. The new MgO-C bricks displayed a number of impressive physical properties, such as a high oxidation resistance and the ability to form a solid-liquid phase.
Enhanced silicon carbide refractory bricks have proven to be successful in the aluminum market. These products are manufactured using the most appropriate grain sizing and optimal raw materials to provide superior alkali attack resistance. They feature a 50% alumina brick to provide thermal protection. They are also designed to pass aggressive alkali attack testing.
In addition to alkali test resistance, THORBIDE products also provide a minimal penetration rate in alkali tests. This allows for an unburned carbon-free brick solution to enhance quality and reduce energy loss. The products are also manufactured with optimal grain sizing and optimized grain orientation to provide industry leading service life.
In addition to the high strength of silicon carbide refractories, the products have excellent oxidation resistance. These characteristics make them suitable for use in the process industries, particularly in aluminum reduction cells.
These products also have excellent thermal shock stability. They are also used as insulating linings in furnaces. They are lighter, thinner, and stronger than traditional silicon carbide kiln furniture. Their lower energy consumption also reduces production costs.
Metallurgical, building construction and chemical industries are three different sectors that require the application of chemicals to help improve the performance of their products. Chemicals can be used to improve the strength of concrete, extend the life of construction works and protect against environmental hazards. These chemicals are used in construction from scratch and in repair and rehabilitation. Adding chemicals to a building increases its durability and helps reduce the amount of water used in construction.
Chemical industries transform inorganic and organic materials into usable products. The production processes in these industries are typically continuous, but some of them are also batch processes. Some of the products are directly consumed, while others are used as raw materials for other industries.
The raw materials used in these industries are primarily natural and come from the earth. Process industries use aqueous, thermal and electrolytic processing to produce their products. The products include materials for construction, printing, rubber and plastic industries.
