当今,随着核能发电大规模地迅速发展,出现了运行10万小时或更长时间的燃煤电站的维修问题。通常,经营者们希望在安全裕度允许下使机组的使用寿命延长到15万小时以上,但正是由于这种类型的火电站必须满足昼夜和季节性尖峰负荷变化之需要的运行特性(增加苛刻的热运行工况瞬变次数).阻碍了这一宏伟计划的实现。本文探讨了Alsthom—Atlantique 为估算潜在寿命而做的定子铸钢冶金学研究方面的问题,其系发表在1981年第2期《试验与评价》中题为“铬钼钒铸钢的淬火、回火和时效”一文的第2部分。
Nowadays, with the rapid and large-scale development of nuclear power generation, the maintenance of coal-fired power plants running 100,000 hours or more has emerged. Often, operators want to extend the life of a unit to more than 150,000 hours with safety margin, but precisely because of the operational characteristics required for this type of thermal power plant to meet the changing diurnal and seasonal peak loads (increase Harsh thermal operating conditions transients.) Hinder the realization of this grand plan. In this paper, we discuss Alsthom-Atlantique’s study of stator steel metallurgy for potential life expectancy, published in the February 1981 issue of “Testing and Evaluation” entitled “Chromium, Molybdenum and Vanadium Castings, Fire and Aging ”part 2.
