摘    要:冷床炉熔炼技术是一种先进的钛合金熔炼技术,经一次熔炼可生产出无偏析、无夹杂的优质钛合金。介绍冷床炉的发展概况,对比工业化冷床炉和真空自耗炉的特点和工作原理,指出冷床炉在操作控制和夹杂物去除方面的优势。同时,介绍宝钢特钢的等离子冷床炉和电子束冷床炉。

Abstract: The cooling hearth melting technology is advanced melting technology. The high quality titanium alloy ingot can be produced by single melting. The development survey of cooling hearth melting was introduced. The character and working principle were contrasted. The advantage on manipulation control and removal of inclusion was pointed out. At the same time, plasma cooling hearth melting (PACHM) and electric beam cooling hearth melting (EBCHM) were introduced in detail.
