摘要： A low cement refractory gun mix is disclosed. The gun mix comprises a coarse refractory portion having a particle diameter of at least 74 microns and a fine powder portion having a particle diameter of at most 74 microns. The gun mix is prepared by forming the fine powder portion into a slurry and deflocculating it prior to mixing it with the coarse refractory portion rather than deflocculating it when it is introduced into a spray gun. The gun mix has an extremely low cement and water content. Accordingly, a sprayed deposit of high packing density can be obtained which is equal in quality with deposits produced by vibration molding or casting. The gun mix is appropriate for use in forming the entire work lining of containers for molten metal.

摘要翻译： 公开了一种低水泥耐火枪混合物。 喷枪混合物包含粒径至少为74微米的粗耐火材料部分和粒径至多为74微米的细粉末部分。 通过将细粉末部分形成浆料并在将其与粗耐火材料部分混合之前将其反絮凝而不是将其在其被引入喷枪中时将其反絮凝来制备枪混合物。 枪组合具有非常低的水泥和水含量。 因此，可以获得与通过振动成型或铸造产生的沉积物质量相同的高填充密度的喷涂沉积物。 枪组合适合用于形成熔融金属容器的整个工作衬里。
