OG EXHAUST GAS DUCT OF CONVERTER, AND SELF-FLUXING ALLOY THERMAL SPRAYING METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an OG exhaust gas duct of converter excellent in resistances to impact, abrasion, and corrosion; and a method and apparatus for self-fluxing alloy thermal spraying whereby a structure after a fusing treatment is not distorted even when the structure is platy or cylindrical and is not highly stiff. SOLUTION: The OG exhaust gas duct has a self-fluxing alloy thermal spray layer 2 on is inner peripheral surface and an alloy layer 3 formed thereon by the self-fluxing alloy and the duct material. In a fusing method for a self- fluxing alloy thermal spray layer thermally sprayed on the surface of a cylindrical or platy structure, the thermal spray layer is heated together with the opposite side of the thermal spray layer. A fusing apparatus used therefor is also provided. COPYRIGHT: (C)2003,JPO
