Abstract

PURPOSE: To increase build-up ratio of sprayed material to the part to be repaired, by, in repairing the damaged part of the refractory lining of a converter etc. with spray of refractory material, regulating the quantity of water to be added to the refractory material to be sprayed in correlation to the temp. of the surface of the repairing part.
CONSTITUTION: In repairing the damaged part 9 of refractory lining 8 of a hot metal ladle, a mixer furnace, a converter etc., change in temp. of lining with time is measured from the point of time when the furnace is emptied, and is converted to time axis. Before the start of spraying of refractory material, surface temp. at the damaged part 9 is measured by means of a thermometer 13. The data is fed to an arithmetic control unit 15, thereby the kind of the refractory material to be sprayed, the distance between a spray nozzle 3 and the damaged surface 9, quantity of the material to be sprayed, and suitable quantity of water to be added are computed. The temp. of the damaged part 9 is inputted by a clocking means 14, and the quantity of water is controlled suitably by a water-supply control unit 16 and a control unit 17 for supply of refractory material to be sprayed so as to effect spraying.
