Further, the concrete technology 1. in 21 rolling mills round steel pass on the basis of former 17 frame aperture types pass arc
Degree reduces 4mm, and roll gap reduces 1.8mm, and the round steel passes of the 22 rolling mills pass radian on the basis of former 18 frame aperture types maintains not
Become, roll gap reduces 0.9mm, and remaining rolling groove remains unchanged.
Further, the concrete technology 2. in 15 rolling mills round steel pass on the basis of former 13 frame aperture types pass arc
Degree reduces 8mm, and roll gap reduces 1.5mm, and the round steel pass schedules of the 16 rolling mills pass radian on the basis of former 14 frame aperture types is tieed up
Hold constant, roll gap reduces 1.5mm, and remaining rolling groove remains unchanged.
Further, the concrete technology 2. in, in roll the typically short stress roll of 13,14 framves and be changed to 15,16 frame Gao Gang
Spend carbon tungsten roller ring.
Further, the technique optimizes suitable for high-speed rod-rolling mill rolling pass.
Further, the technique rolled suitable for high-speed rod, pre- finish rolling, the Combinatorial Optimization of finishing mill rolling pass.
Further, the technique is applied to the road suboptimization of high-speed rod different size.
Compared with prior art, the beneficial effects of the present invention are：1）General idea of the present invention is ingenious, practical, existing
Field application is convenient, extensive；2）The technical scheme reduces sky relatively and crosses distance, improve rolling by being optimized to rolling pass
Stability；3）This patent is applied to all size of high-speed rod and each sortie, if it is desirable, can pass through above-mentioned thinking
Optimize improvement；4）The technical scheme cost is relatively low, is easy to promote the use of on a large scale in Steel-rolling Industry.
