Cold Forming Process Mill Rolls For Cold Rolled Carbon Stainless Copper Aluminum Steel Pipes
I. Features of cold rolled steel pipes
1. Cold-rolled precision steel pipe has high tolerance and dimensional accuracy, and the product accuracy is controlled within ±0.05mm. The inner and outer walls have good smoothness and no oxide layer on the surface;
2. The application of cold-rolled precision seamless pipes can save steel, improve processing efficiency, reduce processing procedures and equipment investment, save costs and greatly save mechanical processing man-hours, increase production volume and material utilization, and help improve product quality and reduce costs.
II. The purpose of cold rolled tubes
Cold rolled precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, pneumatic cylinders, petrochemicals, electric power, ships, bearings, pneumatic components, medium and low pressure boilers and other fields. The cold rolled materials are carbon steel, stainless steel, copper alloy steel, aluminum, etc.
III. What is mill rolls and it's role
The mill rolls and mandrels are key parts of cold pilger mill. The upper and lower two pieces form a pair, which are assembled on main frame. The rolls are randomly framed for periodic reciprocating motion. The mother tube undergoes five stages of diameter reduction, pressure rolling, rough rolling, finishing rolling and sizing under the action of rollers to obtain high-precision finished tubes. The tolerance of finished tubes can be ±0.05mm and less.
