Formation of the structure of a film of hydrous sodium silicate on the surface of a refractory chromite filler. Wastes of contact cleaning of oils were used as organic additives, which are calcium bentonite impregnated with oils. The structure of liquid glass films on the surface of a refractory filler, cured at a temperature of 180-400-600-900 ° C, is investigated, which is comparable to the temperature convective system of liquid glass molds and rods, as well as the temperature system of molds after pouring with hot metal.
