average taphole service life(In spite of the rapid increase in the average taphole service life, its performance is not stable. 尽管出钢口平均寿命迅速提高，但其性能却不稳定。)
SEN life(Subsequent refinement of mold practices and SEN design results in achieving a 13 heat (599 minute) SEN life and a monthly average of over 8 heats per SEN. 由于结晶器操作和浸人式水口设计的持续改进，浸人式水口寿命已达到13炉(历时 599min), 月平均浸人式水口寿命超过 8 炉。)
campaign of blast furnace(It has been found that the benefits from injecting waste plastics into blast furnace include reducing coke rate and emission of carbon dioxide, and increasing productivity and campaign of blast furnace.. 人们已经发现，高炉喷吹废塑料的优点包括既可降低焦比和二氧化碳排放，又可提高高炉利用系数和寿命。)
