三十万(瓦千)工业动力机组因锅炉事故而仃车的主要原因是在它运转了一万～二万小时后,由于本身的蠕变和锈蚀损耗使锅炉蒸汽过热器和用12Cr1MoV钢制做的下部辐射管件发生故障。金属的使用寿命设计为十万小时。因此,提高锅炉钢管的可靠性就成为热电站最主要的问题之一。解决这个问题的有效方法是将现有的珠光体类热稳定钢经过形变热处理(M.T.O)来促进亚组织的强化。
The main reason that the 300,000 (TWD) industrial power unit is stopped by a boiler accident is that after it has operated for 10,000 to 20,000 hours, its boiler steam superheater and the 12Cr1MoV steel The lower radiation tube made failed. The service life of the metal is 100,000 hours. Therefore, to improve the reliability of boiler steel has become one of the most important issues of thermal power plants. An effective way to solve this problem is to promote the strengthening of the sub-structure by subjecting the existing pearlite-type heat-stabilized steel to the heat treatment of deformation (M.T.O).
