High Precision 18 High Reversible Cold Rolling Mill For Stainless
Steel
For high quality metal strip cold rolling, high precision 18High
(18 rollers) cold rolling mill require very high precision
manufacture and more investment with advantages:
- More thickness reduction than normal rolling mill in each rolling
process. For example, a 18 high rolling mill can reduce HR
stainless steel strip from 2.0mm down to 0.3mm with no need of
interim annealing.
- Can give better quality of CR metal plates, better flatness.
- Less power consumption for the same production.
- In some applications, only multiple high rolling mill can achieve
the required performance.

Company Profile
We are metal coil sheet processing machine manufacturer and
supplier, we dedicate to supply of good quality machines and
provision of complete services.
We work in the coil processing machine field for over 20years, we
design and make each machine customized. From machine parts
materials selection, each part machining and treatment, whole
machine assembly and surface painting, we carefully note each
detail of whole production process to achieve good quality machine
result.
Rich Experiences:
Our people witness the developing process of sheet processing
machines and develop ourselves with market, thus able to supply
customers good machines at competitive prices.

Efficient Responses:
Investment of metallurgical equipment is a system engineering,
which requires comprehensive plan and successive execution. The
efficient responses of the equipment suppliers are very important.
We did well in this and cooperate with customers for long time.

Senses of Mission:
