Product Description

Product Description

High Quality Calcium Aluminate Refining Slags

Refining slag series are important material that is applied in the ladle furnace refining process, to purify the molten iron by deep desulfuration and deoxygenation. The refining slag series include pre-melted refining slag, sintered refining slag and synthetic refining slag, its main content is CaO and Al2O3. Premelted refining slag is a necessary additive to form basic refining slag used in secondary metallurgy to desulphurise and refine steel.

Detailed Photos

Family of synthetic slags developed in the form of sintered, pelletized or blends according to customer needs, with application in primary or secondary refining, steel pans and iron-alloys, with specific objectives, such as: absorption of inclusions; desulfurization of steel; sulfur stabilization.We produce briquetted synthetic slag based on a mixture of powdered corundum and other raw materials with a high content of alumina, which is the main active ingredient of the product. Using a suitable combination of synthetic slag with lime and other slag-forming additives, we can produce basic refining slag with a low melting point. The slag is active and fluid, which is exactly what is needed to produce high-quality steel with low sulphur content and low content of undesirable inclusions.

New required steel grades need the production of more alloyed, clean and desulphurized steels. This metallurgy demands the use of synthetic slags and slag additives more efficient and complex. According to that Aleastur has developed a wide range of products to get slags more actives.

Metallurgical applications

• Homogeneous synthetic slags generation
• Alternative flux to CaF2
• Good protection against H2 /N2/O2 pick up
• Capacity of S absorption
• High capacity of absorption of steel inclusions
• Free Fluorine slags
• Addition of MgO in order to reduce refractory wearing
• High melting speed

Synthetic Slag is normally packed into 1 mt jumbo bags.

Our Advantages

Product advantages1,Calcium Aluminate Refining Slags has sufficient conditions for metallurgical requirements such as stable physical and chemical properties, low melting point and low viscosity.2,The pre-melted refining slag does not contain F, H, N, C and other impurities, which can effectively improve the quality of refined steel;3,the content of MgO is reasonable and stable, and will not corrode the furnace lining and ladle; 4,the structure of the refined slag is dense and can be stored or stored Transportation is very convenient; 5,the cost is stable and the slag formation speed is fast, which can reduce dust pollution during the refining process of the steel plant. In addition, practice has proved that the deoxidation, desulfurization and impurity adsorption functions of the pre-melted refining slag produced by our plant are relatively better than those of its counterparts, and the unit consumption is reduced by 20%.
