Entities directly under the enterprise include the no . 1 iron mill , the no . 2 iron mill , steel mill , steel rolling mill , h - beam mill , sintering plant , oxygen plant , electric power plant , real estate development company , environmental protection material company , guolong industry and trade company , and fujian xinghua trade company 企业下设的直属单位有一炼铁厂、二炼铁厂、炼钢厂、棒材厂、 h型钢厂、烧结厂、制氧厂、发电厂、房地产开发公司、达隆工贸公司、国隆工贸公司、福建兴华贸易有限公司。
Taking advantage of the abundant local iron ore and coal materials , the iron pipe factory pipe fitting factory and cast iron factory , in order to meet the local market demand , developed products of four series with 300 items . these items are divided into two categories , mainly centrifugal cast iron pipe , pipe fittings , stainless steel joints and clamps , art - enclosure , seamling steel pipes , manhole , covers and balance weight iron 炼铁厂铸管厂和管件厂根据市场需求和当地丰富的优质生铁煤炭资源优势，形成一条的生产优势。开发出四大系列三百多个品种的产品，分灰口铸铁和球墨铸铁两大类，主要有离心铸管管件井盖配重铁等。
In recent years at iron - making plant of pangang , the coke ratio of pig iron has reduced evidently by insisting on “ burden preparation ” course , improving quality of sinter , raising wind temperature , increasing rich oxygen quantity and injecting abundant pulverized coal into bf . the solid fuel consumption of sinter has been decreased greatly through insisting on using high - quality calces , practising high feed sintering , actualizing many techniques in solving key problems . at the same time , the energy source base management has been strengthened , and energy - saving work has made great progress , profits generated by energy - saving have exceeded a hundred million yuan 近年炼铁厂通过坚持“精料”方针，改善烧结矿质量，提高风温，增大富氧，实施大喷煤，使入炉焦比有明显下降；烧结坚持用好生石灰，推行厚料层烧结，实施多项技术攻关，固体燃耗大幅度下降；同时加强能源基础管理，节能工作取得长足进步，节能创效益1亿元以上。
The project comes from hefei iron and steel company " s no . 3 blast furnace control system . intrinsic control pattern of no . 3 blast furnace control system had more problems , as a result , they infected the control system functions . it used much more manpower and restricted the improvement of output and quality 本课题来源于合肥钢铁公司炼铁厂3 #高炉控制系统自动化改造，原有的3 #高炉控制系统在生产工艺和控制模式上都存在着很多问题，因而在一定程度上影响了整个系统的自动化水平，而且人工耗费量大，制约了产量和质量的提高。
