美国钢铁学会和能源部共同投资着手了一项以熔融冶炼、二次燃烧和喷煤为基础的直接炼钢新工艺的研究开发计划。新工艺不同于现代敞开间歇式钢铁工艺,而是封闭连续式炼钢工艺。新工艺直接用煤。此项工艺成功以后,特大大降低基建投资和操作费用,节约大量能源,并使环境得到很大的改善。现选译其中的工艺描述、开发目的和工艺基础等部分如下。 1.工艺描述
The American Iron and Steel Institute and the Department of Energy jointly invested in a research and development program for a new direct steelmaking process based on melt smelting, secondary combustion and coal injection. The new process is different from the modern open intermittent steel technology, but closed continuous steelmaking process. New technology directly with coal. After the success of this process, it will greatly reduce capital investment and operating costs, save a lot of energy and make the environment greatly improved. Now the process of selecting the translation of the description of the purpose and process development and other parts are as follows. 1. Process description
