天津炼铁总厂炼钢分厂有3座50t转炉,年产钢水150～180万t,配备有4台R6m4-4连铸机,生产150mm方坯,已于1996年底实现全连铸,并对连铸机进行高效改造,以尽快实现三机对三炉全连铸生产。目前已高效改造完第一台,达标后即与一座转炉相匹配,实现一机对一炉生产。下一步拟逐步改造第二 Tianjin Iron and Steel Plant Steel Plant has three 50t converter, with an annual output of 150 ~ 1.8 million tons of molten steel, equipped with four R6m4-4 continuous casting machine, the production of 150mm billet, has been fully continuous casting at the end of 1996, and The continuous casting machine for efficient transformation, as soon as possible to achieve three full furnace three furnace production. At present, the first unit has been transformed efficiently and matched with a converter after reaching the standard so as to realize the production of a machine to a furnace. The next step is to gradually transform the second
