Anyang Heli High-speed Cold Rolling Co., Ltd.

Anyang Heli high-speed Cold Rolling Co., Ltd.has located high-tech development area in An yang , which have invested **0 million and occupied about *0 thousand square meter . It is staff **0 and more than *5 technology mangments that is professional producting High-ductility cold-rolled ribbed steel bars and is the center of research and development , producting and extend. The company for He Li have aimed to the application HRB**0Mpa in China and extending HRB**0Mpa with high strength-toughness steel, which insist in the way for process optimization and bakward elimination. The process equipment , reseach and producting all-in-one to innovation for cold-rolled ribbed steel bars, is rational layout, stable operation, speed adjustable and easy to operate so that the entire production line automation, continuous and high-speed ***** was enhanced substantally elongation for cold-rolled ribbed steel bars, but also achieved the breakthrough progress. Construction steel products by the State Quality Supervision and Testing Center of detection, yield strength to ******5 Mpa, the tensile strength to ******5 Mpa, elongation A5 reach *8.5 percent to *2.0 percent, high intensity, with good extension, to complete the mechanics of reinforced **0 Mpa Performance indicators. The new process has the following characteristicsƒ‚ (1) Through the technology of tempering temperature control to significantly improve product elongation, to obtain good mechanical properties and to overcome the industry problem for the low ductility of cold-rolled ribbed steel . (2) It was combined the technology and tempering so that the sum of the two strengthening effect to further enhance the steel with strength and toughness, which developed into a science of cold-rolled deformation heat treatment technology, and promoting large-scale industrialization of product development and realize the cold rolled steel with ribs a major breakthrough in product optimization process
