Mill Finished Galvanized Gravity Roller Large Steel Cylinder Rollr Industrial Steel Rollers

To the user's requirements,we can make many patterns,such as square dot,circle dot,diamond,cross,striation and any regular and irregular patterns.
Our hot roller has been ever for west germany and taiwan hot rolling machine and we have ever made the largest asian hot roller (φ720x5400mm).
Laser cutting machine for thermo-calender roller promotes the rollers' quality.

Material of hot roller/thermo-calender roller

Best quality alloy steel as material,molding after mechanical maching and heat treatment.
Surface hardness HRC58~62
 

Way of heating:

central hollow inner pipe screw heating
peripheral drilling heating

Production Process:

1. The material of the roller body is generally selected from high-quality seamless steel tubes (special materials can be customized according to user needs). After boring and grinding the inner hole, the thickness of the tube wall is uniform, and then it is made by welding, stress relief treatment, turning, grinding, and finishing;

2. Correct the static balance and dynamic balance treatment; the coaxiality of the finished roller ≤0.02mm;

3. According to the pattern, different processing techniques are adopted to achieve a clear pattern, exquisite pattern, rich levels and precise size of the extruded product.

4. The final surface is plated with hard chrome or other treatments, and the hardness can reach HRC58-62.
