唐钢有两个转炉炼钢厂,一炼钢厂有四座公称容量为6吨的氧气侧吹转炉,设计能力年产钢24万吨:二炼钢厂有三座公称容量30吨的氧气顶吹转炉,设计能力年产钢90万吨。唐钢的连铸生产已有较远久的历史。1957年一炼钢建成一台立式连铸机,到1984年才达到设计能力,产坯5.2万吨。到1986年,全公司连铸比很低,仅为5.07％。“七五”期间,唐钢把发展连铸
Tangshan Iron and Steel has two converter steel mills, a steel mill has four nominal capacity of 6 tons of oxygen side blowing converter, designed to produce 240,000 tons of steel an annual capacity: two steel mills have three nominal capacity of 30 tons of oxygen top blowing Converter, the design capacity of an annual output of 900,000 tons of steel. Tangshan continuous casting production has a long history. In 1957, a steelmaking plant was built as a vertical continuous caster until 1984, achieving design capacity of 52,000 tons of billet. By 1986, the whole company had a very low continuous casting ratio of only 5.07%. During the “Seventh Five-Year” period, Tangshan Iron and Steel to develop continuous casting
