Ladle Filler Sand
With the development of continuous casting technology, the original ceramic stopper has been replaced by sliding nozzle + drainage sand. As people's requirements for the quality of molten steel continue to increase, it is necessary to automatically open the ladle. If the pouring cannot be started automatically, it needs to be boiled with an oxygen lance to assist drainage, which will cause a considerable amount of molten steel to be poured open, causing secondary oxidation, affecting the quality of molten steel, increasing pouring costs, and threatening the safety of equipment and operators.
Description:
Our ladle 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 steel making practices. This is achieved through custom blending which
affords each customer a product specific to their manufacturing needs. Working with each
customer we can evaluate and offer a sand product to optimize their free open performance.
