Cold-rolled ribbed steel wires and bars is a kind of two sides or three sides crescent bars,using common low carbon steel (I level steel) by cold-rolled decrease dia. many times, compression rib once and eliminata internal stress. During the 1990s, it has been spread by building material Department of China,but the king of bar dont heating treatment after cold-rolled in domestic marketing,its tenacity and plasticity is poor and dosage is a little. Due to these reasons, our company is coopreation with many cold-rolled equipment enterprises, bring into suitable induction heating equipment in cold-rolled production line. By power distribution reasonable, control temperature technology delicate and auto control technology easily, the equipment could adjust handy bars intensity, tenacity, plasticity and so on. At the same time, bar appear yield obviously, yield strength is get to above 500Mpa. Plasticity index is improving from 10% to 18% more or less. After heating treatment,bars each index conform to GB13788-2008 standard,it is about to spread( exceed heat-rolled III level standard). The surface of bar has blue layer of oxide as thin as a wafer, brightness and beautiful.
