The important role of high alumina aggregate in steelmaking
1、 The principle of action of high alumina aggregate in steelmaking
High alumina aggregate is a metallurgical raw material rich in aluminum, mainly composed of aluminum salts and silicates. During the steelmaking process, high alumina aggregates can play the following roles:
1. Scope adjustment function
High alumina aggregates can improve the composition of molten iron by increasing the content of alloying elements, thereby enhancing the mechanical properties and corrosion resistance of molten iron. At the same time, the alkaline oxides in high alumina aggregates can neutralize the acidic oxides in slag, thereby adjusting the alkalinity of slag, reducing impurities such as silicon and manganese in slag, improving its fluidity and slag removal ability, and ensuring the purity of molten steel.
2. Cleaning function
Aluminum salts in high alumina aggregates can react with impurities such as aged alumina, silicon, calcium, and magnesium in molten steel to generate gases, promoting the cleaning effect in the steel. At the same time, silicates in high alumina aggregates can react with carbonates in slag to generate gas, forming bubbles in the slag to remove impurities and achieve the purpose of purification.

2、 Application Practice of High Aluminum Aggregate in Steelmaking
The application of high alumina aggregates in steelmaking has been widely adopted, generally in two ways:
1. Join directly:
Directly add high alumina aggregate into the molten steel for adjustment. This method is suitable for some production and processing methods, such as EBT furnaces, where the addition of high alumina aggregates can improve the composition, quality, and performance of molten steel.
2. Adding furnace materials:
Adding high alumina aggregates to steelmaking and circulating them through the furnace material for range adjustment and purification purposes. This method is suitable for smelting methods such as blast furnaces, converters, and electric furnaces. The addition of high alumina aggregates in the furnace charge can reduce impurities during the process and improve the fluidity and purity of the molten steel.

Common specifications: 0-1mm, 1mm-3mm, 3mm-5mm, 5mm-8mm, etc.
High alumina aggregate (calcined bauxite) is our company's star product, with an annual output of nearly 200000 tons. We can customize products with different indicators and particles according to customer needs, and provide free samples.

What is the role of bauxite in casting?

In modern industry, casting technology plays an important role in various fields. In the casting process, bauxite, as a widely used material, has many amazing characteristics and powers. This article will provide a detailed introduction to the role and advantages of bauxite in casting processes.

Bauxite, also known as kaolin, is a natural mineral composed of silicate minerals containing aluminum, silicon, oxygen, and other elements. It has good chemical stability and high temperature stability, and plays an indispensable role in the casting process.

Firstly, bauxite is mainly used as a refractory material in casting. At high temperatures, bauxite can maintain its structural stability without melting or deformation. This makes it an ideal material for making refractory bricks, refractory coatings, and refractory lining plates. These materials serve as insulation and protection in casting and melting furnaces, effectively resisting high temperatures and corrosion.

Secondly, bauxite can also be used to make casting molds. In the casting process, molds play a crucial role, directly affecting the quality and accuracy of castings. Bauxite is widely used in mold manufacturing due to its excellent plasticity and fire resistance. It can have a certain strength and hardness after appropriate treatment, allowing the mold to withstand pressure and temperature changes during the casting process.

In addition, bauxite is widely used as a flux and fluxing agent. In the casting process, in order to ensure that the metal alloy can fully melt and have good fluidity, flux and fluxing agent are essential. Bauxite can provide molten liquid at high temperatures, promote the dissolution and melting of metals, and enable castings to obtain uniform composition and pure structure.

In addition to the above applications, bauxite can also be used as a filler and reinforcement material. In the casting process, in order to increase the strength and hardness of the casting, it is usually necessary to add some fillers or reinforcing materials. Due to its unique particle shape, large specific surface area, and plasticity, bauxite can increase the density of the internal structure of castings, improve the strength and wear resistance of the material.

In summary, bauxite has multiple roles and advantages in casting processes. From refractory materials to mold manufacturing, from fluxes to fillers, bauxite can play its magical role in every aspect. It not only improves the quality and performance of castings, but also makes important contributions to the development of casting technology.

High alumina bricks
High alumina brick is a type of refractory material, and the main component of this refractory brick is AL2O3.
If the Al2O3 content is higher than 90%, it is called corundum brick. Due to differences in resources, standards are not completely consistent across countries. For example, European countries have set a minimum Al2O3 content of 42% for high alumina refractory materials. In China, the Al2O3 content in high alumina bricks is usually divided into three grades: Grade I - Al2O3 content>75%; Grade II - Al2O3 content is 60-75%; Grade III - Al2O3 content is 48-60%.
