1959年,当钢流除气被明确地规定作为一种除去合金钢中的氢元素的有效技术时,英国钢铁研究协会便转向另一问题,即采用什么类型的设备才能处理除大型锻钢件用的以外的其他钢液。当时,经验已经证明,真空处理除了能除去钢中的氢以外,还可达到其他目的。1959年所采用的钢流除气设备有其固有 In 1959, when the run-off of gas was clearly defined as an effective technique for removing hydrogen from alloy steel, the British Iron and Steel Institute turned to the question of what type of equipment can be used to deal with large forgings Other than the liquid steel used. At that time, experience has shown that vacuum treatment can achieve other goals besides removing hydrogen from the steel. The steel flow degassing equipment used in 1959 was inherent
