Abstract

PURPOSE:To form a heat and wear resistant coating for a blast furnace tuyere and to elongate the tuyere life by adding one or more kinds of finely divided, specified substrances in formation of a molten layer of a specified metal on the base metal surface of the tuyere. CONSTITUTION:When wire rod 6 made of copper, Ni, Monel metal, titanium or the like is build-up-welded to base metal 11 by means of tip gas nozzle 2 of a welding torch for MIG welding or the like, fin grains 8 of one or more out of tungsten carbide, titanium carbide, boron carbide, etc. of a fixed grain size are added from supply vessel 5 to molten pool 9 through pipe 4 and grain feeding torch 1 fixed to nozzle 2 with jig 3 at a certain angle, forming tough deposited metal 10. Thus, a superior heat and wear resistant coating of high mechanical strength is easily formed by automatic welding to elongate the life of the title tuyere to 2-4 times as long as that of a conventional method.
