coking coal(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。)
gas-cleaning system(The large diameter and the vertical height of these uptakes prevent excessive amounts of charge material from blowing over into the gas-cleaning system. 这些上升管具有大的直径和高的垂直上升段，能够防止将过量的炉料向上吹人(高炉)煤气净化系统。)
gas stream(Sulfur enters the blast furnace mainly in the coke and is released into the blast furnace gas stream as H₂S or a gaseous compound of carbon monoxide and sulfur (COS) when the coke is burned. 高炉中的硫主要是焦炭带人的。焦炭燃烧时，硫以 H₂S 或气态一氧化碳和硫的化合物 (COS) 的形式释放出并进人高炉煤气流。)
non-coking coal(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。)
