美国伯利恒钢铁公司最近开发了一项称为“活性元素加热”(R.E.Heating)的钢水预热新技术并申请了专利。 R.E.Heeting技术包括浸没燃烧工艺。对于浇注而言,采用浸没燃烧工艺二次加热包中钢水,可提高包中钢水温度。R.E.Heating技术是先在 Bethlehem Steel has recently developed and patented a new technology for preheating molten steel called “R.E.Heating.” R.E.Heeting technologies include submerged combustion processes. For pouring, the submerged combustion process is used to reheat the molten steel in the bag to increase the temperature of the molten steel in the bag. R.E.Heating technology is first
