该项目通过对十余个水泥厂的现埸普查和跟踪调查,弄清了篦板开裂、磨损和氧化的特点和规律,特别是在国内外首次全面实际测定了活动篦板在使用工况下的服役温度、温度分布和变化规律,提出了引起篦板开裂的原因是热疲劳,为篦板合金设计提供了可靠依据。同时,研究了耐热 The project through more than a dozen cement factory census and follow-up survey to understand the grate plate cracking, wear and oxidation of the characteristics and laws, especially at home and abroad for the first time a comprehensive practical measurement of the activities grate plate in use conditions The service temperature, temperature distribution and variation rule of the grate plate are proposed. The reason of cracking caused by the grate plate is thermal fatigue, which provides a reliable basis for the design of the grate plate alloy. At the same time, the study of heat
