bubbling of inert gas into tundish(【技】通过在中间包安装管状气体分配器、多孔透气砖等，将惰性气体均匀喷人中间包，可有效改善钢水在中间包内的流动状态，促进夹杂物上浮并在液面形成保护层。: The bubbling of inert gas into the tundish via a porous refractory lining offers a potential means to enhance inclusion removal. 通过多孔耐火衬向中间包内喷人惰性气体是提高夹杂物去除能力的潜在方法。)
granular coal injection(Ironmaking projects include granular coal injection on No.3 and No.4 blast furnace ($18 million), a revamp and reline of No.4 furnace ($10 million) (completed), and the transfer project for blast furnace gas from No. 5 furnace to the pelletizing plant. 炼铁项目包括 3、4 号高炉粒煤喷吹(1800万美元)，4号高炉改造和大修(1000万美元，已完工)以及5号高炉煤气至球团厂的输送工程。)
injection hopper(用于高炉喷煤: The coal is conveyed approximately 210 m from the injection hoppers to a static distributor (one for each system) located next to the furnace above tuyere level. 由喷吹罐将煤输送到位于高炉附近高于风口平面的静态分配器(每一喷吹系统配备一个分配器)，距离约为 210m。)
fuel injection(【技】从风口向炉缸喷吹燃料并在风口区迅速燃烧气化的技术。它不仅可以节约焦炭，同时还可改善高炉间接还原，有利高炉顺行高产。: Fuel injection at the tuyeres has always been part of normal operating practice on this blast furnace. 风口喷吹燃料已经是这座高炉正常操作的一部分。)
injection of lime with oxygen(Some years ago, it was discovered by French and Luxemburg steel-makers that injection of lime with the oxygen permitted the use of iron of much higher phosphorus content -up to nearly 2 per cent in steelmaking. 若干年前，法国和卢森堡的炼钢工作者发现：将石灰和氧气一起喷吹就可以在炼钢中使用含磷量高达近2%的高磷生铁。)
pulverized coal injection system(The investment will be used to complete facilities under construction, including a pulverized coal injection system at the No.4 blast furnace, as well as a galvanizing line and other renovations to rolling mills. 这项投资将用于完成一些在建的设备，包括4号高炉的一套粉煤喷吹系统、一条镀锌生产线和轧机的更新改造。)
pulverized coal injection equipment(In addition, the relative cost of coal would be significantly lower than the cost of coke it replaced. This led to the decision late in 1991 to install pulverized coal injection (PCI) equipment for all of Inland's blast furnaces. 此外，煤的相对费用远远低于它所替代的焦炭费用。有鉴于此，于1991年年底决定在内陆钢公司所有的高炉上安装粉煤喷吹设备。)
injecting waste plastics into 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，又可提高利用系数和高炉寿命。)
