Self fluxing alloy has the characteristic that objective hardness is provided by performing re-fusion (fusing) after spray. This again molten work is carried out by hands, and stability of the quality and improvement of the work efficiency usually become the problem. Therefore we aim at the quality stability of the self fluxing alloy fusing process and the improvement of the work efficiency by using high frequency induction heating. I utilize induction heating simulation of JMAG as a part of the study.
I performed an induction heating experiment for the boiler tubes which a lot of self fluxing alloy was used for this time. I report the result that weighed the differences between experimental value and analysis level at that time.
