ABSTRACT:
A method of flame spraying refractory material for in situ repair of, e.g., furnace linings wherein an inert carrier gas incapable of supporting combustion and particles of refractory oxide and combustible metal or other oxidizable material are delivered to a flame spraying apparatus wherein high pressure oxygen aspirates and accelerates the carrier gas-particle mixture; a controlled ratio of 5 to 1 to about 30 to 1 oxygen gas to carrier gas; allows for the use of highly combustible metals and materials such as chromium, aluminum, zirconium, and/or magnesium as heat sources without back-flash and at a deposition rate in excess of 2000 pounds per hour of refractory oxide to yield a deposited refractory mass exhibiting enhanced wear and erosion resistance.
