hot rolled seamless steel pipe production line
Hot rolled seamless steel pipe production line is a set of production line consists of machines and equipment that used to produce hot rolled seamless steel pipes. The production line includes products such as uncoiling machine, piercing machine, cold forming machine, heat treatment furnace, sizing machine, cutting machine, etc. It has become one of the most important production lines in modern steel pipe production lines.
The production line is mainly used to produce pipes with small diameter and high wall thickness. Hot rolled seamless steel pipes are mainly used in petroleum, natural gas, water supply and other industries. The production line consists of uncoiling machine, piercing machine, cold forming machine, heat treatment furnace, sizing machine, cutting machine and other parts.
Uncoiling machine is mainly used for uncoiling and pre-leveling of coiled strips. This machine can uncoil materials into several parallel strips. After that, it is necessary to adjust the tension to make the width of each strip consistent. Piercing machine is mainly used for piercing steel strip into proper shape. It is mainly composed of feeding section, cold piercer and host.
Cold forming machine is used for cold forming of steel tubes. It makes the steel tubes deform under the action of axial force. This machine is usually composed of numerical control system and servo motor, roll forming device, press device, etc. Heat treatment furnace is mainly used for heat treatment of steel pipes. The main process includes annealing, normalizing, quenching and tempering, etc.
Sizing machine is mainly used for sizing of steel pipes. It is mainly used to improve the inner and outer diameters of steel pipes. It is divided into two types: single pass sizing machine and multi-pass sizing machine. Cutting machine is mainly used for cutting and ends beveling of steel tubes. This process should ensure accurate in size and quality of the ends.
The production line of hot rolled seamless steel pipes can provide steel pipe with high accuracy, high toughness, good appearance and high reliability. It is one of the most important production lines in modern steel pipe production lines. In recent years, with the development of technology, the production line has been continuously improved in quality and cost.
