Abstract
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.
