Tundish dry material added with ferro-silicon nitride, tundish working lining and preparation method of tundish dry material
The invention provides a tundish dry material added with ferro-silicon nitride, a tundish working lining and a preparation method of the tundish dry material. The tundish dry material is prepared from the following raw materials in percentage by mass: 60%-80% of a regenerated magnesium material, 10%-30% of magnesia, 3%-5% of a binding agent, 1%-5% of an additive and 1%-3% of a sintering agent, wherein the additive comprises a first additive, and the first additive is ferro-silicon nitride. According to the tundish dry material added with the ferro-silicon nitride, the regenerated magnesium material is adopted as the aggregate, recycling of resources is achieved, the cost of the tundish dry material is reduced, the ferro-silicon nitride with the low price is used for replacing silicon nitride, metal aluminum powder and metal silicon to serve as an additive, the cost of the tundish dry material is further reduced, and the utilization rate of the ferro-silicon nitride is increased. Other additives in the dry material are further blended to guarantee the overall performance of the dry material, so that the dry material has excellent anti-scouring and anti-corrosion performance, and the overall service life of the tundish can be remarkably prolonged when the dry material is used for the slag line part.
本发明提供一种添加氮化硅铁的中间包干式料、中间包工作衬及其制备方法，中间包干式料的制备原料包括以下质量百分比的组分：再生镁质料60%‑80%，镁砂10%‑30%，结合剂3%‑5%，添加剂1%‑5%，烧结剂1%‑3%；其中，添加剂包括第一添加剂，第一添加剂为氮化硅铁。该添加氮化硅铁的中间包干式料采用了再生镁质料作为骨料，实现了资源的回收利用，降低了中间包干式料的成本，并且以价格较低的氮化硅铁替代氮化硅、金属铝粉、金属硅作为添加剂，进一步降低了中间包干式料的成本，还通过进一步调配干式料中其他添加剂保证干式料的整体性能，使其具有优异的抗冲刷、侵蚀性能，用于渣线部位能显著提高中间包的整体寿命。
