上海宝钢集团浦东钢铁公司冶金厂新建单流板坯连铸机在2010年10月20日成功完成了第一次连浇,共浇铸2炉中碳钢,总浇钢量约为330 t,平均拉坯速度为1.1 m/min,共浇铸12块板坯。铸坯名义宽度为1 700 mm,厚度为245.4 mm。该厂两天后又进行了一次5炉连浇,浇铸钢种为中碳钢(钢水总量约为820 t),铸机平均拉速为0.9 m/min,共浇铸20块板坯。铸坯名义宽度为2 100 mm,厚度为245.4 mm。该项目的目标是新建一台年生产能力为152.5万t合格坯的板坯连铸机。除普碳钢和微合金钢以外,生产钢种还包括高Ni、高Cr和高Mo特殊钢、最大碳含
Shanghai Baosteel Group Pudong Iron and Steel Company Metallurgical Plant New single-stream slab caster successfully completed the first continuous pouring on October 20, 2010, a total of two cast carbon steel furnace, the total amount of steel poured about 330 t, the average The casting speed was 1.1 m / min, a total of 12 slabs were cast. The nominal width of the slab is 1 700 mm and the thickness is 245.4 mm. Two days later, the plant ran another 5-furnace continuous casting of medium-carbon steel (with a total amount of about 820 t of molten steel) and an average casting speed of 0.9 m / min. A total of 20 slabs were cast. The nominal width of slab is 2 100 mm and the thickness is 245.4 mm. The project aims to create a new slab caster with an annual production capacity of 1,525,000 t qualified billets. In addition to carbon steel and micro-alloy steel, the production of steel grades also include high Ni, high Cr and high Mo special steel, the maximum carbon content
