弾塑性解析による亜鉛鍍金釜内部固体亜鉛が側板と付着している場合の熱膨張が及ぼす影響の把握 : 溶融亜鉛鍍金釜立ち上げ時の釜隅角部応力の把握(その3) Study on Influence of Thermal Expansion of the Inside Solid Zinc Adhering on the Side Wall of Hot Dip Galvanizing Bath by Elastic-plastic Analysis : Stress of the Corner of Hot Dip Galvanizing Bath at Start-up Operation (3rd Report)
At start-up operation of hot dip galvanizing baths to galvanize steel products, several leakage accidents of liquid zinc due to the damage in the vicinity of welded parts between side and bottom plates have been reported. Generally, liquid zinc is transferred to a new bath which has been heated adequately. In some of the accidents, however, it was found that transferred liquid zinc solidified in the bath heated inadequately. In other paper, the author reports the stresses of the bath due to the thermal expansion of solid zinc inside the bath based on unsteady thermal conduction analysis and elastic-plastic analysis with taking effects of temperature and strain rate for the solid zinc into account. This paper reports the results of additional analysis to investigate especially the effect of the expansion of solid zinc on generated stresses.
