METHOD FOR PRODUCING Zn-Al BASE ALLOY WIRE ROD FOR THERMAL-SPRAYED COATING

摘要

PROBLEM TO BE SOLVED: To produce a wire rod for thermal-sprayed coating at a low cost by continuously casting molten Zn-Al base alloy into a bar-state and successively, rolling. SOLUTION: The molten alloy composed of 0.6-22.0 mass% Al and the balance substantially Zn is continuously cast with a belt and wheel caster provided with an endless belt running while bringing into contact with a rotated casting wheel having a circumferential groove in this peripheral surface under state of covering the circumferential groove so that temperature of the cast material when this material separates from the casting wheel becomes≤275°C. In succession to the casting, the temperature of the material to be rolled at the inlet of a rolling mill is made to≤275°C and this material is rolled at≤275°C while using lubricator emulsion.
