Abstract��The reason why there was no obvious yielding phenomenon in the test of the mechanical property of the HRB400 hot rolled ribbed bars produced by the high speed wire rod was analyzed. According to the result of the microscopic structure of the HRB400 wire rod�� the improved scheme was proposed from the two aspects of the adjustment of the chemical composition and the control of the cooling after rolling.
