柯夫(korf)工程公司、美国钢铁公司和明尼苏达州自然资源部将联合向能源部提出一份报告,申请净煤工艺活动基金以建立一座1亿美元的大型KR程序炉。选址在明州的铁山城,靠近美国钢铁公司明塔克(Mintac)粉末冶金厂,建设工期为2年。KR炉出的热金属与高炉出的类似,但不需要焦炭。柯夫工程公司是VOEST-Alpine联合体的一员,它说这种工艺可用各种各样的煤(包括蒸气锅炉用煤)作燃料。主要的顾主将是铸造工业中须要高纯度铁的厂家。净煤工艺基金定为4亿美元,以联邦基金方式来帮助发展净煤技术。但联邦基金不会超过该项目总投资的50％,它将由能源部确定如何分配。(美刊《Technology Update》1986年4月28日期)
Korf Engineering, U.S. Steel, and the Minnesota Department of Natural Resources will jointly submit a report to the Department of Energy to apply for a coal-to-coal process activity fund to build a large KR process furnace worth US$100 million. It is located in Tieshan City, Minmetals, near the US Steel Mintac Powder Metallurgy Plant. The construction period is 2 years. The hot metal from the KR furnace is similar to that from the blast furnace, but no coke is required. Corvette Engineering, a member of the VOEST-Alpine consortium, says that this process can be used as a fuel for a wide variety of coals, including coal for steam boilers. The main custodian will be a manufacturer that requires high-purity iron in the foundry industry. The coal industry process fund is set at US$ 400 million to help develop coal technology through federal funds. But the federal funds will not exceed 50% of the total investment in the project. It will be determined by the Department of Energy how to allocate. (US publication “Technology Update” dated April 28, 1986)
