针对某炼钢厂生产流程建立钢包周转过程仿真模型,对影响钢包周转率的热修时间、生产钢种和修包包龄等因素进行仿真研究.仿真结果表明:热修时间增加,钢包周转率下降,当日产45炉典型钢种,热修时间在0～20 min范围内钢包周转率为6.43,而当热修时间为50～60 min时钢包周转率为5.0;生产不同钢种的钢包周转率差别较大,日产41～50炉的SPHC钢种时,钢包周转率最大值为6.28,最小值为5.63,而生产同样炉数的X70钢种时钢包周转率最大值为5.0,最小值为4.55;修包包龄增加,钢包周转率提高,日产48炉典型钢种,修包包龄为40次时钢包周转率为4.0,修包包龄为45次钢包周转率达极限值6.86.
The simulation model of the ladle turnover process was established for the production flow of a steelmaking plant, and the factors influencing the ladle turnover rate, such as the time of hot repair, the type of steel produced and the age of the ladle were simulated.The simulation results show that the ladle repair rate increases, Decreased, when 45 typical steel grades were produced daily, the ladle turnover rate was 6.43 during the hot repair time range of 0 ~ 20 min, while the ladle turnover rate was 5.0 when the hot repair time was 50 ~ 60 min. The ladle turnover of different steel grades The maximum rate of ladle turnover was 6.28 and the minimum was 5.63, while the maximum ladle turnover rate was 5.0 for the same number of kilns of X70 steel, the minimum was 4.55; the repair package age increased, the ladle turnover rate increased, 48 typical Nissan steel production, repair package age of 40 ladle turnover rate of 4.0, repair package age of 45 ladle turnover rate of 6.86.
