Product Description
Open casting ladle rate reach to 99%, etc. reducing the labor intensity, reducing oxygen drainage, improve the quality of steel products, to ensure the smooth casting process.
This chrome stuffing sand is developed through new production process and optimal formula of flow promoting agent and agglutinant inhibitor.
It improves the natural casting rate without any contamination to the molten steel. Meanwhile our nozzle fill sands have been developed to meet the needs of steel making facilities worldwide. Each blend is carefully designed to enhance the free flow of steel from the ladle regardless of steelmaking practices.
This is achieved through custom blending which affords each customer a product specific to their manufacturing needs.
