Development of Raw Material for Cold Rolled Ribbed Bar

With the aim of improving the adaptability of raw material produced for cold rolled ribbed bar, a series of hot rolled rod coil was developed by optimizing the chemical composition and the cooling process of high speed rolling. The rolling yield of cold rolled ribbed bar was increased obviously after using the developed raw material. The influence of chemical composition and ferrite rate as well as crystal grain size on the property of hot rolled rod coil was discussed. The technical measures of improving the adaptability of hot rolled rod coil were put forward.
