Mill Features
20HI single reversing cold rolling mill
The 20HI single reversing cold rolling mill consists of QY20-HIGH Integral standard version, QY20-HIGH PRO Integral fully automatic plate shape closed-loop high-end version, QY20-SP HI Split standard version, QY20-SP HI PRO Split-type fully automatic plate-shaped closed-loop high-end version
This unit is suitable for processing high-strength steel strips such as stainless steel, silicon steel, and carbon steel. The equipment has the characteristics of high speed, stability, good surface quality of finished products, and excellent shape.

Zero-crown frame design, BC support roller adjustment device, a middle push-pull traverse, with constant rolling gap and constant rolling force, FF, FB, MF etc. thickness control AGC function.

Created brilliant in the industry repeatedly
All kinds of extreme models have obtained great achievements in the industry, including fully self-designed 650mm stainless steel precision cold rolling mill has achieved stable rolling of 0.002mm hand tear steel in Wuxi Huansheng; 2 sets of 1450mm stainless steel cold rolling mill are the first in China to realize remote centralized rolling control; the first in China to design and develop 1780mm ultra-wide stainless steel cold rolling mill.
Qianye Engineering’s 1450mm 20Hi cold rolling mill for silicon steel, based on the integrated experience in the design, installation and commissioning of more than 40 sets of 20Hi mills, and the evolution and improvement of four generations of machines, it currently has the rolling capacity and application performance of all kinds of silicon steel. It can perfectly realize the high temperature aging rolling of high magnetic induction grain-oriented silicon steel and the production of 0.12-0.2mm level silicon steel wide strip.
