基于现代炼钢生产工艺对钢包周转匹配的分析
Analysis of Ladle Turnover and Matching Based on the Modern Steelmaking Process

钢包周转主要受车间平面布局、工艺路线和组产等因素的影响。其周转可分为在线周转和包役周转。结合本厂情况统计分析钢包周转得知：未过LF炉的钢包平均周转时间为91.4或99.1分钟，过LF炉钢包平均周转时间152分钟，需投入4或6个钢包才能满足生产需要。钢包总数主要与产量、包役平均时间和包龄有关。目前在本厂日产180炉，包役平均时间12.37天，平均包龄49.8炉的情况下，钢包要维持在45个基本能与生产相匹配。
Ladle turnover is mainly affected by workshop layout, process route, production plan and other factors. Ladle turnover can be divided into on-line turnover and ladle service turnover. Based on the actual situation of the factory, the statistical analysis conclusion of turnover time shows that the average turnover time is 91.4 mins or 99.1mins without LF refining treatment; the average turnover time is 152 mins with LF refining treatment; 4 or 6 ladles are required to put into used the production. Total number of ladle is mainly related to production, ladle service time and ladle lining life. Under the condition of 180 heats daily capacity, when average ladle service time is 12.37 days and the average ladle lining life is 49.8 heats, the ladle should be maintained at 45 ind that can be matched the process.
