焦煤(In the meantime coke, on which blast furnaces have depended for ever 250 years, is becoming more expensive every year, and supplies of suitable coking coals are becoming scarcer. 在此期间，高炉依赖 250 年之久的焦炭，其价格正逐年攀升，而合适的炼焦煤供应则日渐匮乏。)
焦炉(There is a need to develop next generation coking ovens because the old ovens will have to be replaced but only by environmentally friendly ones. 由于必须使用环境友好型焦炉取代旧焦炉，因而开发下一代新焦炉十分必要。)
非结焦煤(In simplified terms the COREX process applies metallurgical steps usually carried out in a coke oven plant and a blast furnace in a different sequence, thus allowing the utilization of noncoking coal, but producing the same quality of hot metal as in the blast furnace. 简言之， COREX 炼铁法所采用的冶金工艺步骤都是焦炉和高炉通常所采用的，只不过是按另一种顺序来完成。这样，它就利用非炼焦煤，却能生产出与高炉铁水质量相同的铁水。)
