Cold rolling machines is used to reduce the temperature of the material being worked with while also increase how hard and strong the material gets during the rolling mill process. During this process, the overall finish and granule structure of the material is made more pure and workable.
Our cold rolling machines are usually set for four vertically aligned rolls which makes for reduction of pressure forces to be evenly distributed. The overall outcome of this process is a to produce a higher quality, thicker finished product whiteout changing the width or length of the material.
The cold rolling process can be performed in various forms to produce different finishes and harnessed depending on the end users wants and needs and usually reduces the material somewhere between 0.5% all the way up to a 50% reduction.
Advantages of cold rolling machines
- Thickness is controlled & maintained.
- The surface quality becomes uniformed and the grain structure improves.
- Yield, thickness and length are controlled by the amount of times the material is run through.
Disadvantage of cold rolling machines
- ore force is required to reduce the material.
- Stronger, more expensive equipment is required.
- Deformation under tension is increased.
- Prepping material for cleanliness is crucial.
- May cause residual stress down the road.
