钢包互用条件及影响因素

为深入研究炼钢厂多台连铸机间钢包产生互用的条件及影响因素,以H炼钢厂的钢包为研究对象,简要解析了钢包运行过程及运行时间。分析了钢包周转次数、周转数与浇铸炉次数之间的关系;运用甘特图模拟出两台连铸机浇次重叠时间为50min条件下的钢包运行过程。研究表明:钢包产生互用的前提条件为钢包在先停浇连铸机不再承担运输任务,且先停浇连铸机的钢包空包结束时间应在后开浇连铸机钢包的重包开始时间之前。分析了浇次重叠时间对钢包互用的影响,结果表明:浇次重叠时间内连铸机浇铸的钢包数少于围绕连铸机周转的钢包数时才能产生钢包互用。研究了连铸机单炉浇铸时间与钢包周转周期对钢包互用的影响,结果表明:科学控制钢包周转周期和连铸机单炉浇铸时间,合理匹配二者关系,可使浇次最后不需要周转的钢包数增加,提高钢包的互用几率。

Precondition and influence factors of steel ladle interaction

For further research on the precondition and the influence factors of ladle interaction among continuous casters, we took steel ladle of H steelmaking plant as the research object and analyzed the operation process and time of steel ladles. The relationship among turnover times, turnover numbers and cast numbers were analyzed. And the steel ladle''s turnover process of 2 continuous casters with overlapping time of 50 min was simulated with Gantt chart. The simulation results show that the precondition of steel ladle interaction is the steel ladle no longer undertakes the transport task at 2# continuous caster and the empty ladle''s ending time is prior to heavy ladle''s starting time of 1# continuous caster. After researching the influence of overlapping time on ladle interaction, it''s concluded that the precondition of steel ladle interaction is the cast number during overlapping time is less than the turnover number of steel ladle. By researching the influence of turnover cycle and casting time of single ladle on ladle interaction, it''s showed the rational control and matching can raise the non-turnover number and probability of steel ladle interaction.
