recycle(【技】返矿：: The dust is largely removed from the gas stream in a hot gas cyclone and is then recycled to the process. 在热煤气旋风除尘器中，这些炉尘的大部分从煤气流中清除，随后返回到工艺流程中再利用。)
recover(废料: Conway Steel has developed a technology to recover zinc and iron from electric arc furnace dust by a shaft furnace that is similar to the blast furnace operation. 康韦钢公司开发出一项利用竖炉从电弧炉炉尘中回收锌和铁的技术。该竖炉的操作与高炉操作相类似。)
production rate(【参】在英文原版炼铁专业文献中，用 production rate 来表达"利用系数"或"高炉利用系数"的频率明显低于 productivity。: An increase in blast furnace production rate from 7.2 to 8.9 tonnes/day/100 cu ft working volume, was obtained during trials with natural gas injection. 在喷吹天然气试验期间，高炉利用系数由 0.072 提高到0.089 t/(d ft³) (吨/天/立方英尺)工作容积。)
integrated waste plastics recycling system(In Japan, NKK has completed construction of an integrated waste plastics recycling system in which processed plastics are injected into the Keihin Works' No.1 blast furnace. 日本钢管公司已完成了废塑料综合循环利用系统的建设。经过该循环利用系统处理过的废塑料喷人京浜港钢厂 1 号高炉。)
furnace availability(Several steel companies have converted to slag splashing in an effort to lower refractory replacement costs and increase furnace availability by reducing the delays associated with furnace refractory relines. 一些钢铁公司转而采用溅渣护炉技术，努力降低耐火材料更换费用，通过降低炉子更换耐火衬耽搁的时间提高炉子的作业率。)
sinter strand productivity(The sinter strand productivity increased from 20. 8t / m²/ day to 25.7 t / m²/ day in three years of operation. 在三年运行期间，烧结机利用系数由20. 8t/m² • d 提高到25. 7t/m² • d。)
