用当代先进的钢铁生产工艺和技术建设新型钢铁厂

To Build A New Type of Iron And Steel Plant with Advanced Production Technologies

计划建设的北仑钢铁厂是采用ＣＯＲＥＸ炼铁、转炉炼钢、薄板坯连铸连轧的全新的紧凑式钢铁厂。ＣＯＲＥＸ是用非炼焦煤与氧气的熔融还原炼铁法，取代传统的高炉、焦炉、烧结组成的炼铁系统。薄板坯连铸连轧将近终形连铸与直接轧制相结合，缩短了传统连铸与轧钢工艺流程。采用这二种技术使钢铁生产流程变得简洁、紧凑。ＣＯＲＥＸ煤气考虑用以生产海绵铁热压块与燃气轮机联合循环发电。

Beilun Iron & Steel Plant to be built is a completely new compact iron & steel enterprise, where COREX ironmaking, converter steelmaking and thin slab concast & conroll process are adopted. COREX ironmaking means that conventional ironmaking system with blast furnace, coke oven and sintering circuit is replaced by melting reduction ironmaking with non-coking coal and oxygen.Thin slab concast & conroll combines the near net shape continuous casting and the direct rolling together, thus to shorten the conventional continuous casting & rolling process. For COREX gas utilization,two possibilities of producing hot briquette iron (HBI) and gas turbine combined cycle power generation are taken into consideration.
