Abstract
In order to produce required high strength steel bars for the building industry, it is necessary to provide steel with correct compositions. Effective, controlled micro-alloying is very important in the production of high strength steel bar of consistent microstructure and hence mechanical properties and weldability. Through adopting a series of measures such as molten iron pretreatment, converter final control, argon, calcium treatment, vanadium nitride and so on, a proper way to make high strength steel bar was given. The results show that the strength of the steel bars for the building industry can be increased by micro alloying with vanadium nitride. Favorable metallurgical achievements and economical benefits were gained.
