机电部西安电炉研究所和天津第三炼钢厂联合研制的炼钢电弧炉微机控制网络系统,于1992年12月在天津第三炼钢厂炼钢车间投入运行。该网络系统为国内首次采用,具有很大的潜在市场。 该网络系统目前由九台下位机,三台中位机和一台上位机组成。由下位机和中位机组成的三台炼钢电弧炉微机控制装置,于1989年起陆续投入运行,在两年多可靠运行的基础上,1992年12 Electromechanical Department of Xi’an Electric Furnace Institute and Tianjin No. 3 Steel Works jointly developed steelmaking arc furnace computer control network system, in December 1992 in Tianjin No. 3 Steel Works steel plant into operation. The network system for the first time in China, with a great potential market. The network system currently consists of nine lower computer, three central computer and a host computer. By the next crew and the central unit of the three steel arc furnace computer control device, put into operation in 1989 after another, based on more than two years of reliable operation, in 1992 12
