中厚板轧制头部弯曲研究现状浅析

ANALYSIS OF THE RESEARCH STATUS FOR HEAD WARPING AND BENDING DURING PLATE ROLLING PROCESS

通过对国内外中厚板轧制生产、实验研究及理论模拟研究的对比分析,指出了中厚板头部翘曲程度与变形程度、上下工作辊速比等因素的关系目前研究成果不一致,说明了有必要对提出的理论和技术方法深入研究,对各种因素的影响进行定量实验、检测、数值解析,建立模型,以适应实际生产的需要。

The comparing and analyzing of the production experiment and theory stimulation both at home and abroad to the head warping and bending during plate rolling process were performed, it was described that the research conclusions at present were different about the relationship among the head warping and bending degree of plate and the pass reduction, and the ratio of rotate speed by upper roll vs lower roll. In order to build models to satisfy the requirements of production, the further study was needed on the published theory and technology methods, and the systematical tests, checking and stimulation about all kinds of effecting facts should be carried out.
