Steel liquid Refining agent

Steel refining agents are widely used in the smelting and casting industries. They are aimed at refining different types of steel such as stainless steel, carbon steel, alloy steel, special steel, etc. in steel mills and precision casting plants. They are a product composed of many alloy elements and various activating elements. They are a refining additive that many domestic and foreign manufacturers can choose. After being used by many manufacturers, they can help you and your company reduce production costs to a large extent, and their effect is equivalent to that of external refining.

Composite refining agent, mainly composed of highly active aluminum oxide, small amounts of magnesium oxide, silicon dioxide, as well as over 15% active metal aluminum powder and a small amount of salt substances that have been melted. The packaging is 10kg per small bag, plus ton bag packaging, moisture-proof inner plastic packaging.

Due to the difficulty in deoxidation, desulfurization, dephosphorization, and degassing during the smelting and casting process of stainless steel, heat-resistant steel, alloy steel, etc; Steel contains a large amount of high melting point alloying elements, which are prone to produce inclusions after melting. Due to the fact that the melting point of these inclusions is generally higher than the existing steelmaking temperature, they cannot be melted and removed, resulting in defects such as pores, cracks, cold shuts, and shrinkage porosity, which reduces product quality and has a significant impact on the mechanical properties, especially toughness, of the steel. After forming the steel parts, many defects are more likely to appear inside and on the surface. The use of our company's steel liquid refining agent can prevent, reduce, and eliminate defects in the smelting and casting process and make up for technical deficiencies. The effect after use is significantly compared. The activated elements contained in this product have a low melting point, which can refine the grain size, enhance the fluidity of molten steel, eliminate waste gas in the steel, strengthen deoxidation, desulfurization, and dephosphorization, remove metal and non-metal inclusions in the steel, and further purify the steel.

Main functions:

Purify the steel liquid and remove exhaust gases from it. It has the function of strengthening deoxidation, desulfurization, and dephosphorization, which can significantly reduce the amount of inclusions in the steel liquid. The refining agent has the functions of slag making and agglomeration, making it easier to separate liquid slag. By mixing liquid and gas, it effectively eliminates waste gas and prevents the formation of pinholes. Defects such as slag inclusion, ash inclusion, pores, nodules, and cold shuts can be completely avoided. Refining grain size, enhancing the fluidity of molten steel, can adjust the viscosity of molten steel, and avoid cold shut phenomenon. Improve the mechanical properties of steel, greatly enhancing its toughness and plasticity. There are almost no broken edges or fractures during the rolling process, improving the internal and external quality of the product, avoiding cracks, and increasing the yield of the product.

Usage:

1. It is recommended to use refining agents after conventional deoxidation, as the amount of this refining agent is small and cannot completely replace the existing reduction and deoxidation processes.

2. Usage: 0.2% to 0.3% of the actual weight of molten steel.

3. When the steel liquid begins to pour into 1/3 of the ladle, put the refining agent into the ladle and pour the steel liquid as soon as possible.

If there is crust or slag on the surface of the steel liquid, a slag remover should be used to remove the floating slag on the surface of the steel liquid before pouring.

During transportation or storage, attention should be paid to waterproofing and moisture-proof measures. Store in a dry environment. If it is damp, please dry it before use.
