A salt bridge model, which takes into account mass transfer of components between the two fluids, was developed and proved successful in interpreting the effects of composition on explosiveness in the smelt-water system. The model is based on the fact that the main smelt constituent, sodium carbonate, is not soluble in water at temperatures approaching the critical point, while certain other constituents are soluble. The soluble substances allow a substantial increase in the critical temperature of the solution, which in turn shifts the range of contact interface temperatures at which spontaneous explosions can occur (between the spontaneous nucleation temperature and the critical temperature of the coolant) to higher values. The model was able to provide an explanation of why sodium chloride, sodium hydroxide, and sodium sulfide act as smelt sensitizers and a semiquantitative definition of the concentration ranges in smelt and in the quench solution where spontaneous explosions are likely 相似文献

轧机芯棒是冶金行业连续式轧管机轧制无缝钢管的主要工装之一,芯棒的需求量与无缝钢管的产量同比增长。轧机芯棒直径为107~277mm,其工作长度一般为15~18m,属于超长杆件。目前芯棒所用材料为美国热作模具钢H13(4Cr5MoSiV1)。通过对国产芯棒材料的冶炼、锻造和热处理试验,获取了大量试验数据,经过筛选和优化,获得了H13钢轧机芯棒的热处理生产工艺,为实现计算机辅助热处理工艺设计(CAPP)提供基础数据,同时也对H13钢的应用进行深入探讨。 相似文献
