The Variety and Technology of Cold Forming Selectional Steel

Currently, in the manufacturing of cold bending and hollow square rectangle-shaped steel, there are two types of different developing processes. One is to be round first and after that to be square or rectangle-shaped. One more is to be rectangular or square straight. For the time being, in the field of developing square and rectangular steel tubes, to be square as well as rectangular directly is the most advanced creating modern technology in a global society. The modern technology to be rectangular or square straightly is advanced than that of being rounded very first and afterward being square or rectangle-shaped. The innovation of being round initial and after that being rectangle-shaped or square will certainly be harmful to steel band or product of plate rolling considerably while the one to be square and rectangle-shaped right will not damage the materials, which can maintain the mechanical as well as physical homes, ensuring the top quality of the product. It is understood that a huge steel pipe factory in Tai’an, Shandong, is making use of the direct square and rectangular forming modern technology, which has a fantastic molding effect.
