Hot rolled square rectangular square pipe Angle square pipe" detailed introduction

A basic introduction to hot - rolled rectangular square tube

Rectangular rectangular tube: rectangular rectangular tube whose R Angle is not more than one times the wall thickness.

Angular rectangular tube: when the wall thickness is no more than 3mm, the R Angle is no more than 1mm;When the wall thickness is 3-8mm

When R Angle is not greater than 2mm;When the wall thickness is more than 8mm, R is no more than 3mm, which is a sharp rectangular tube.

Properties of hot - rolled rectangular rectangular square tube

2. Research and development purpose of rectangular rectangular tube with right Angle/sharp Angle

Mechanical guide rail, agricultural machinery framework, steel and wood furniture rectangular rectangular tube and curtain wall construction of rectangular rectangular tube, due to the need for tolerance and cooperation, the other square rectangular tube size requirements, need to use high-precision rectangular rectangular tube, which these customers * concern about the plane of rectangular rectangular tube.At present, the production of rectangular tube is mainly made by cold drawing and continuous bending of steel plate, and the flatness of finished steel tube cannot meet the needs of customers.The square moment tube is manufactured by the progressive roll extrusion technology, which has the potential of ** controlling the plane size of the finished steel tube by improving the machining accuracy of the working roller and continuously adjusting the assembly spacing of the roller system.

Technical parameters of hot - rolled rectangular square tube

Square rectangular tube with right Angle/sharp Angle

Rectangular square tube size range is:

Side length: 30mmx30mm~400mmx400mm, wall thickness: 1mm~16mm;

Rectangular tube size range is:

The side length is 30mmx50mm~300mmx600mm, and the wall thickness is 1mm~16mm.

Instructions for hot - rolled square rectangular square tube

1. The square rectangular tube is processed and manufactured by the progressive roll extrusion technology, and the square rectangular tube of different materials and specifications is collected for the flat surface rebound. The square rectangular tube is analyzed by variance analysis and experimental design, and the flat surface rebound curve of the square rectangular tube is drawn.

(note: welded rectangular rectangular tube can be used as raw material hot rolled strip steel, by cold bending forming, or formed into a round tube square, after heat treatment;(2) seamless rectangular rectangular tube, the raw material is hot rolled seamless tube directly formed by hot rolling or by cold forming)

2. According to the theory and practice of roll flattening, design and manufacture rollers with different final roll crown required for products with different material strength requirements for processing are used for production.

3. Strictly control the machining accuracy of working roller and improve the control accuracy of finished square moment pipe flatness.

4. The assembly spacing of the roller system is adjusted continuously to ensure the product is parallel to the plane of both sides.
