Cold rolled pipe mill is an equipment used for producing cold rolled pipes, mainly used for processing various specifications and materials of cold rolled pipe products. It usually consists of multiple components, including a feeding system, a curling system, a cold rolling system, a shaping system, and a cutting system.
The working principle of a cold rolling pipe mill is to roll metal strips through multiple rollers to obtain the desired shape and size without heating. This cold working method can improve the strength and hardness of the metal, while avoiding possible deformation and damage during the hot rolling process.
Cold rolled pipe mills are widely used in fields such as construction, machinery, automotive, aerospace, etc. The cold-rolled pipe products produced have the characteristics of smooth surface, precise size, and stable performance. In modern industrial production, cold rolling tube mills have become one of the indispensable and important equipment.

Equipment Introduction

1.Periodic cold rolling mill is a process equipment that utilizes annular dies to perform cold, reciprocating, and periodic rolling on metal tubes and bars. This type of equipment offers excellent performance in terms of both diameter and wall reduction, resulting in excellent product mechanical properties and surface quality. It significantly reduces the number of production process passes required to form tubes and bars.
2.Classified by the number of rolls, this model is divided into 2-roll rolling mills, 3-roll rolling mills, 5-roll rolling mills, etc. The more rolls there are, the higher the quality of the product. At the same time, the lower the machine speed, the lower the output. From the perspective of the continuity of feeding, this model is divided into continuous feeding rolling mills and stop-feed rolling mills. In terms of speed, they are classified into low-speed, medium-speed and high-speed models.
3.At present, the market trend of steel pipe and steel bar manufacturers is to replace traditional drawing machines with high-speed rolling mills to obtain higher production capacity while reducing production and management costs.
4.High-speed continuous rolling mill is different from ordinary rolling mill in that it achieves the balance of rolling reaction force by changing the transmission structure of rolling braking force, and minimizes the impact inertia force to obtain smaller rolling vibration force and higher rolling speed, thereby improving product quality and uninterrupted feeding to obtain greater production capacity. At the same time, since high-speed rolling mills are generally fully automatic models, one person can operate multiple machines simultaneously, thereby reducing labor costs and comprehensive equipment production costs.
