Process and system for manufacturing hot-rolled seamless pipe

Abstract

This paper presents a process and system for manufacturing hot-rolled seamless pipe. The process consists of several steps, which include heating and forming the steel, rolling the pipe, and heat treating the pipe. The system includes a variety of components and processes, including a furnace, a rolling mill, and a heat treating chamber. The system is designed to produce high-quality, consistent hot-rolled seamless pipe with a wide range of sizes and grades.

Introduction

Hot-rolled seamless pipe is a type of steel pipe that is produced by hot rolling and then forming the steel into a circular shape. The process is often used to produce pipe of a range of sizes and grades, which can then be used in a variety of applications in the construction, automotive, and energy industries. The process of hot-rolling seamless pipe is complex and requires a variety of components and processes, including a furnace, a rolling mill, and a heat treating chamber. This paper will describe the process and system for manufacturing hot-rolled seamless pipe.

Process

The process for manufacturing hot-rolled seamless pipe consists of several steps. The first step is to heat and form the steel into a round shape. This is done using a furnace, where the steel is heated to a high temperature and then formed into a circular shape with the help of a mandrel. The second step is to roll the pipe. This is done using a rolling mill, which consists of two large rollers that are used to flatten and shape the pipe. The third step is to heat treat the pipe, which is done in a heat treating chamber. The pipe is heated to a high temperature and then cooled at a controlled rate. This process helps to increase the strength and durability of the pipe.

Production process of hot-rolled seamless stainless steel pipe

The raw material of the hot-rolled seamless stainless steel pipe production process is a round pipe billet, which is cut into a pipe material about 1m long by a cutting machine, and sent to a furnace to be heated to about 1250°C for piercing, and then rolled by a pipe rolling machine for reuse. The steel pipe can be formed by punching the billet with a tapered drill bit.

The hot rolling production process is: round tube blank → heating tube blank → piercing → three-roll cross rolling, continuous rolling or extrusion → heating of blank tube → determination of diameter → heat treatment → straightening of finished tube → finishing → inspection → storage.

System

The system for manufacturing hot-rolled seamless pipe consists of several components and processes. The first component is a furnace, which is used to heat and form the steel into a round shape. The second component is a rolling mill, which consists of two large rollers that are used to flatten and shape the pipe. The third component is a heat treating chamber, which is used to heat treat the pipe. The fourth component is a cooling system, which is used to cool the pipe at a controlled rate. The fifth component is a quality control system, which is used to ensure the pipe meets the desired specifications.

Conclusion

This paper has presented a process and system for manufacturing hot-rolled seamless pipe. The process consists of several steps, which include heating and forming the steel, rolling the pipe, and heat treating the pipe. The system includes a variety of components and processes, including a furnace, a rolling mill, and a heat treating chamber. The system is designed to produce high-quality, consistent hot-rolled seamless pipe with a wide range of sizes and grades.
