    摘要： The present invention relates to a Weak Pre-Deoxidation Process (abbreviated as W.P.D. process) for producing Al-killed and/or Ti-Killed steel. In this process the proper amount of Si-containing ferro-alloy is added into molten steel during tapping, as Weak Pre-Deoxidation, then the ladle is transferred to Al-Wire feeder system or ladle injection treating equipment to proceed final stage of deoxidation. Not only can the recovery rate of deoxidizer be increased by this new process, but also the cleanliness as well as surface and internal quality of products are effectively improved. Besides, the production cost will be reduced due to less deoxidizer addition, less billet conditioning cost, less rejection and less customer claim. Thus the W.P.D. process is a break-through in present steelmaking practice.

    摘要翻译： 本发明涉及一种用于生产杀死Al和/或Ti-Killed钢的弱预脱氧工艺（缩写为W.P.D.工艺）。 在这个过程中，适当量的含硅铁合金在攻丝期间被加入到钢水中，作为弱预脱氧，然后将钢包转移到Al-Wire进料系统或钢包注射处理设备进行脱氧的最后阶段。 这种新工艺不仅可以提高脱氧剂的回收率，而且可以有效提高产品的清洁度，表面和内部质量。 此外，由于减少了脱氧剂添加量，减少了坯料调节成本，减少了拒收和较少的客户要求，生产成本将会降低。 因此，W.P.D. 过程是目前炼钢业务的突破口。

    摘要： The present invention relates to a steelmaking process, in which the molten pig iron produced in a blast furnace is desiliconized, dephosphorized, decarburized and desulfurized. The characteristic of this invention is a sequence and combination of the refining steps. Namely, the steelmaking process of this invention has individual separate refining steps for realizing a removal reaction of the impurities. The objective reaction is the desiliconization in the first step, the dephosphorization in the second step, the decarburization in the third step and the desulfurization in the fourth step.

    摘要： Method of building a direct smelting plant comprising a metal smelting vessel (11) and ancillary plant components such as the components of a hot air supply station (24), an offgas treatment station (32), a solids feed station (41), a hot metal desulphurization station (47) and hot metal and slag launders extending from the smelting vessel (11). The ring track (53) of a ringer crane (51) is installed in front of location at which vessel (11) is to be installed. Crane boom (54) is laid out along elongate stretch of the building site which becomes a corridor (60) between major ancillary components when plant is fully erected. Boom (54) is connected to crane carriage (52) and hoisted to provide high lift capacity over a ground area embracing proposed site of vessel (11) and ancillary components. Prefabricated components are then lifted by crane (51) into appropriate position for final installation. After installation is completed boom (54) is laid down along corridor (60) and crane (51) is dismantled and removed, leaving corridor (60) as an access laneway.
