Product description
High Speed Tube Mill Machine
this tube mill processes steel strip thicknesses ranging from 0.8mm to 3.0mm and achieves production speeds of up to 120 m/min.
Equipped with advanced forming and high frequency welding technology, the LT(60) Tube Mill delivers excellent tube roundness, accurate dimensions, and strong weld quality. The line is suitable for manufacturing tubes used in construction, furniture, automotive components, mechanical structures, and various industrial applications.
Built with durable components and intelligent control systems, the LT(60) Tube Mill ensures stable operation, reduced downtime, and high production efficiency. LOTOSFORMING provides complete turnkey solutions, including machine installation, operator training, and technical support to help customers maximize productivity and product quality.
Working flow:
Raw material (steel coil) → uncoiling → shearing and butt-welding → material accumulating → non-power leveling → mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → Turkish head → cold saw cutting → run-out table
