二炼钢作为一个转炉——连铸厂,主要生产冷轧、热轧薄板及硅钢片,在原设计上有两个问题考虑不够。 1.炉子容量过小与1600铸机不相匹配。生产证明,稍有耽误,钢水容易冷却,不能连铸,甚至不能事故模铸,造成钢水反罐报废。并给周转的钢罐造成桶底凝钢,不能参加周转使用,造成大罐紧张。为了不停产,有时被迫带桶底出钢,据一、二月份的不完全统计,一月有53次,二月桶底1.5吨以上出钢的有35次,三月统计较全面如表1: 被迫带桶底出钢是一种不正常的生产,特别对小钢包是不准许的。上钢一厂、大冶钢厂的100吨钢包都采用在线烘烤以保证大罐内衬温度。在二炼钢的条件下,被迫采取
Two steelmaking as a converter - continuous casting plant, the main production of cold-rolled, hot-rolled sheet and silicon steel, two problems in the original design is not enough. 1. The furnace capacity is too small and 1600 caster does not match. Production proved that a slight delay, the molten steel is easy to cool, can not be continuous casting, or even accidental casting, resulting in molten steel anti-tank scrapped. And to the turnover of the steel drum caused the bottom of the condensate steel, can not participate in the use of turnover, resulting in large tank tension. In order to stop production, sometimes forced to strip the bottom of the steel, according to incomplete statistics in January and February, 53 times in January, more than 1.5 tons at the end of February at the end of steel tapping 35 times more comprehensive statistics in March 1: Forced to strip the bottom of the steel is an abnormal production, especially for small ladle is not allowed. On the steel plant, Daye Steel 100 tons of ladle are baked online to ensure that the tank liner temperature. In the second steelmaking conditions, forced to take
