WANG Dezhi
Abstract：Based on different specification steel bar factory and production line equipment in Shandong steel laiwu branch, microalloyed controlled rolling and controlled cooling is applied. The rolling methods are explored for the four production lines according to different specifications of steels. The different process models are formed such as the common rolling, weak cooling after hot rolling, strong cooling after rolling. These three ways can meet requirements of different user. The lower cost and the efficient production for ribbed bars can be realized.
