- Nippon Steel and Kobe Steel is using steel mill dust and iron ore fines from their steel mills as raw materials to produce direct reduced iron (DRI) and to recover zinc. For this purpose, a joint venture company called Nittetsu Shinko Metal Refine Co., Ltd. was established in October 2008 within Nippon Steel's Hirohata Works.
- Nittetsu Shinko Metal Refine installed a recycling plant that utilizes Kobe Steel's FASTMET(r) Process. In this process, steel mill dust is heated to a high temperature in a doughnut-shaped Rotary Hearth Furnace (RHF) and quickly undergoes reduction to make DRI. At the same time, the zinc in the steel mill dust is recovered. The DRI can be used as an alternative to purchased scrap and iron ore as the main raw material, and the recycled zinc can reduce the use of zinc ore. Recycling also promotes zero emissions.
- Nittetsu Shinko Metal Refine is recycling the steel mill dust and using it to produce DRI. The DRI is supplied to Nippon Steel and Kobe Steel, with a portion also going to Sanyo Special Steel Co., Ltd., a group company of Nippon Steel.
2.联合业务的目的
- 从钢制过程中回收副产品
（生产竞争性铁单元）
该合资企业计划通过回收钢铁磨坊粉尘来生产竞争性的铁单元，这是钢铁生产工艺的副产品。从全球的角度来看，这项回收业务是一种极为有效的措施，以应对以新兴国家为中心并升级原材料价格的钢铁需求急剧增加。欧洲杯足球竞彩
- Promotion of Regional Recycling and Zero Emissions
通过联合业务，Nippon Steel和Kobe Steel都将能够覆盖更广阔的钢防尘回收和零排放区域。联合业务通过整合了Nippon Steel在回收和有效利用钢灰尘的回收和有效利用方面建立的Kobe Steel和操作专业知识所建立的工艺技术，超越了每个公司的框架。
除了新业务外，Nippon Steel还在其Hirohata工作中使用其其他三个尘埃回收厂来回收来自日本Kansai地区的钢铁制造商（包括联盟合作伙伴）产生的钢铁厂灰尘。
