Technological Process of 500MPa Hot-Rolled Ribbed Steel Bar

Abstract:

During the state when China’s economy is highly developed and the investing for engineering construction is growing year by year, high strength steel bar has become the most wildly used constructional materials for architecture. 500MPa hot-rolled ribbed steel bar satisfied the requirements for quake-proof and wide-span construction materials for it’s high strength, good ductility and good weldability, 500MPa hot-rolled ribbed steel bar can be produced through different methods, such as micro-alloying, TMCP (thermo mechanical control process), post-rolling residual heat heattreatment. Microalloying process increased the strength and toughness, but the weldability decreased. TMCP and post-rolling residual heat heat-treatment can save the cost of micro-alloying elements, while the demand of equipment is much higher.
