摘　　要：由于生产组织模式的调整，特钢小型优钢生产线逐渐暴露出孔型系统共用性差、产量低、质量不稳定等问题。针对这些问题，优化孔型系统，并优化孔型在轧辊上的配置，减少换辊次数。改进后，轧机作业率提高20％，年产量提高到40万t。As a result of the adjustment of the production organizational mode , the Special Steel Plant＇s semicontinuous roiling line for light section revealed problems such as poor pass sequence sharing , low productivity and quality instability. In view of these problems, the pass sequence and the pass positioning on rollers were optimized to reduce the number of roll changes. After improvement, mill production rates increased by 20% and annual output to 400, 000 tons.
