A material with good fluidity after mixing with water, also known as a pouring material. After molding, it needs to be properly cured to make it condense and harden. It can be used after baking according to a certain system. The grouting material is made of aluminum silicate clinker, corundum material or alkaline refractory clinker; the lightweight pouring material is made of expanded perlite, vermiculite, ceramsite and alumina hollow sphere. The binder is calcium aluminate cement, water glass, ethyl silicate, polyaluminum chloride, clay or phosphate. Admixtures are used depending on the application, and their function is to improve the construction performance and improve the physical and chemical properties.
The construction method of the grouting material includes a vibration method, a pumping method, a pressure injection method, a spray method, and the like. The lining of the grout is often used in conjunction with metal or ceramic anchors. If added with stainless steel fiber reinforcement, it can improve its resistance to mechanical vibration and thermal shock resistance. The grout is used as a lining for various heat treatment furnaces, ore calcining furnaces, catalytic cracking furnaces, reforming furnaces, etc., and also used as a lining of a melting furnace and a high-temperature melt flow tank, such as a lead-zinc melting furnace, a tin bath, a salt bath. Furnace, tapping or tapping trough, steel drum, molten steel vacuum circulation degassing device nozzle, etc.
