Advanced formulation of Tundish Plaster creates a uniform, highly adherent coating that speeds up the tundish preparation process. This sacrificial layer is chemically neutral and does not react with the melt, preserving the purity of the steel and preventing the formation of harmful inclusions. Its exceptional resistance to thermal shock and rapid drying significantly reduces the time it takes for the tundish to return to production. This product provides you with process optimisation and reduced overhead costs by extending the life of the permanent layer.
Our tundish plaster, whether sprayed or troweled, provides a dense, crack-free coating on the permanent layer. It creates a non-stick surface that prevents melt penetration and seamlessly separates the frozen slag layer after casting is complete. This easy-release property speeds up the tundish cleaning process (deskulling), reduces downtime and directly contributes to increased profitability by reducing refractory consumption per ton of steel produced.
To protect the permanent tundish lining from corrosion and abrasion caused by direct contact with molten steel, a layer of refractory mass about 30 mm thick is applied to it by trowel. This part, called the “working layer” or “sacrificial layer”, plays a vital role in the continuous casting process. Its main function is to completely drain the molten steel remaining in the tundish without causing damage or reducing the useful life of the permanent layer. In addition, the refractory lining prevents the temperature of the molten steel from dropping until it is transferred to the casting mold; therefore, it must have low heat transfer characteristics to prevent energy loss. The correct operation of this layer not only improves the quality of the produced steel but also increases the overall efficiency of the production line and the life of the equipment. Choosing the right material and precise implementation of this lining are the main requirements for optimal operation in the steelmaking industry.
Tundish plaster with a special formulation and high thermal resistance protects the inner layers of the tundish against wear and corrosion caused by direct contact with molten steel. The low heat transfer coefficient of this product maintains the melt temperature within the optimal range and prevents heat loss during the process. This feature ensures the stability of casting conditions and the final quality of the steel. Using our high-quality plaster makes it easy to drain the remaining melt and reduce damage to the permanent layer, thus minimizing repair costs and production downtime. Our company produces plasters in accordance with global standards by using premium raw materials and advanced technology. Our expert team offers timely delivery, technical advice on implementation and competitive prices to increase your productivity and reduce costs. By choosing our tundish plaster, ensure stable performance and longer life of your equipment!
