Three-roll rolling tube technology

Three-roll rolling tube technology is the most advanced seamless steel tube rolling technology in the world today, firstly developed in Italy’s Innse company in the 1990 s. Its main characteristic is the fast production, large range of rolling steel tube specifications, products of high quality. But the technology equipment is complex, difficult to control, high positioning accuracy.



The production of seamless steel tube is mainly used in the oil drilling, high pressure boiler tube, and many other fields.180 mm three-roll rolling unit is a key equipment to produce the diameter of 60 mm ~ 180 mm high quality seamless steel tube. 



For a long time, the equipment can only rely on import in our country, the core technology and equipment is possessed by the international well-known machinery manufacturers SMS Meer (Innse) and Danieli. Due to various reasons, and form a complete set of electric control system is provided by international famous electric business for a long time. In recent years, along with the domestic technology level, the improvement of mechanical design and manufacturing, and electrical control, through research and development design, manufacturing and debugging operation, not only the development of localization of equipment with completely independent intellectual property rights, but also possess the complete sets of production capacity, break the foreign technology monopoly and fill the domestic blank.
