| 摘 要： | 搪玻璃反应釜是一种由玻璃衬层和金属基底材料复合在一起的化工设备。这种设备在制作过程中由于坯体件结构形式、焊接、压力加工工艺，环境（温度与湿度）条件，搪瓷釉及涂搪工艺等原因，均将产生残余应力，而残余应力是自相平衡且不稳定的内力，当其释放应力达到或超过金属坯体与瓷层之间密着强度时即发生爆瓷，使坯体腐蚀失效，从而降低了搪玻璃反应釜的安全可靠性和经济性。为了有利于今后产品造型工艺的改进，对产品进行了残余应力标定和测试，并结合具体产品进行了分析

| Abstract: | Glassed steel reaction vessel is a sort of equipment for chemical engineering by coating a glass lining on metal body. Due to the influence of body structure,welding and press process, environmental conditions (temperature and humidity etc.),vitreous enamel and enamelling technology etc, the residual stress is inevitable.This residual stress is not stable. When it is released and it reaches or excesses the adherence between enamel and metal body the chipping or pelling should happen. Then the reaction vessel is easy to be corroded. In order to improve manufacturing technology examination and analysis of residual stress is carried out in this work. |
