Wire rod and bar new generation of production line,to reach the cost reduction and quality improvement,controlled rolling and cooling technology and its equipment application research is the key.The paper introduces the mechanism and key points of controlled rolling and cooling of wire rod,as well as the requirements for mill design.The structural characteristics of the new modular mill were analyzed,and the modular mill selection parameters and typical control rolling and cooling process layout were given.The controlled rolling and cooling process using modular mills for the actual production of rebar,The results show that the produced products have higher grain size grade and better quality,and can meet the requirements of product standards,without adding micro-alloys such as Nb and V,and the content of Mn alloys are reduced.
