镀锌锅的过早腐蚀和失效开裂 ,导致镀锌成本的上升和生产的极大损失。针对某单位的锌锅在投入使用时 ,即产生开裂失效的现象 ,通过对锌锅原始断口形貌和金相组织 ,X荧光光谱全成分分析、拉伸力学性能和拉伸断口形貌及锌锅受力情况的数值模拟等的研究结果表明 :锌锅钢板中存在的沿晶渗碳体是锌锅过早开裂失效的重要原因
Galvanized pot corrosion and failure of premature cracking, resulting in the cost of galvanized rise and production of great losses. For a unit of zinc pot when put into use, that is the phenomenon of cracking failure, through the original fracture morphology and microstructure of zinc pot, X-ray fluorescence spectra of the full component analysis of tensile properties and tensile fracture morphology and zinc The results of numerical simulation of the stress state of the pot indicate that the intergranular cementite existing in the zinc pot is an important reason for the failure of the zinc pot premature cracking
