Abstract

A method of forming a coating on the refractory flame-exposed surfaces of a high temperature furnace includes the steps of mixing a finely powdered chrome ore composition comprising predominantly chromite which is insensitive to the operating temperature of the furnace and which determines the heat-resisting properties of the final furnace surfaces, and from 1 to 6% by weight of a suspension agent, said chrome ore composition containing more than enough iron oxide to form an iron chrome spinel, the free iron oxide amounting to between 4 and 6% by weight and serving as a fluxing agent, spraying the cement slurry under high pressure and in progressive fashion upon the flame-exposed surfaces of the furnace while the furnace is in operation to form a heat-resisting coating thereon, and utilizing the furnace heat, first, to activate the fluxing agent and produce a fusing bond between the chrome ore composition and the furnace surfaces as the coating is gradually built up by the spraying operation and, second, to set and harden the coating, after it has been bonded to the furnace surfaces and convert it into a solid integrated sheet mass. The suspension agent may be colloidal clay or carboxy methyl cellulose. The composition may also contain other oxides such as the magnesia-alumina spinel and ferric oxide, small amounts of sodium oxide and silica, a binding agent such as sodium silicate and a dispersing agent such as a sulphonated petroleum product.
