What is the purpose of Single Stand Multi-Groove Reducing Rolling Mill
1、 Basic definition of equipment Single Stand Multi-Groove Reducing Rolling Mill: With only one main stand, multiple holes and slots with different diameters are made on the rolling mill rolls. One device can switch and roll various outer diameter specifications of bars and pipes. Different from multi stand series tension reducing mills, it has low investment, small footprint, and fast specification change, mainly for cold rolling/warm rolling small profiles.

What is the working principle of High-Precision Micro Flat Wire Rolling Mill
The core principle of High-Precision Micro Flat Wire Rolling Mill is to use multi pass, extremely small roll gap, closed-loop measurement and control cold rolling to gradually press round wire (or square wire) into ultra-thin, ultra narrow, precision rectangular/flat wire with a tolerance of ± 0.001~± 0.005 mm, without mold throughout the process, and directly shaped by the rolling mill.
