Tundish Covering Agent Production by Leading Industry Manufacturer

Tundish Covering Agent Manufacturers An Overview

In the steelmaking process, the tundish plays a crucial role as the intermediary vessel that holds molten steel before it is cast into molds. One of the key challenges faced during this stage is the formation of dross and excessive oxidation of the molten metal. To mitigate these issues, tundish covering agents are utilized. These agents serve as a protective layer over the molten steel, reducing the contact between the steel and the atmosphere, thereby minimizing oxidation and improving yield. This article delves into the role, benefits, and manufacturers of tundish covering agents in modern steel production.

What are Tundish Covering Agents?

Tundish covering agents are typically composed of a mixture of organic or inorganic materials that create a film over the surface of the molten steel. Common materials include ceramifiable materials, carbon-based compounds, and powders that can absorb harmful gases. These agents come in various forms, including granulates, powders, and pastes, and their selection depends on several factors, including the type of steel being produced and the specific operating conditions of the tundish.

Importance of Tundish Covering Agents

The application of tundish covering agents is vital for several reasons

1. Oxidation Prevention The primary function of these agents is to minimize the oxidation of molten steel. By creating a barrier between the steel and the air, they reduce the formation of harmful oxides, which can negatively affect the quality of the final steel product.

2. Dross Formation Reduction Dross is an undesirable byproduct that can form on the surface of molten metal. Covering agents help to limit dross formation, leading to improved yield and quality of steel.

3. Temperature Maintenance Tundish covering agents can also help to maintain the temperature of the molten steel. By reducing heat loss through evaporation, these agents ensure that the steel remains at optimal temperatures throughout the casting process.

4. Enhanced Fluidity A proper covering layer can improve the fluidity of molten steel, aiding in smoother casting and reducing the potential for defects in the final product.

5. Easier Cleaning and Maintenance With reduced dross and oxidation, tundish maintenance becomes easier, leading to less downtime and improved operational efficiency.
