Abstract：The design of quad-splitting rolling process for the British standard B500BD Φ13 mm hot-rolled rib steel bar in the bar mill of Shiheng Special Steel Group Co.,Ltd.was introduced.From the measures that improve the rolling mill stiffness,optimize the guide structure,improve the temperature process control accuracy,optimize the roll pass sequence,adjust the tension between the mill stands,and the steady rolling of the British standard B500BD Φ13 mm ribbed steel bar quad-splitting rolling process was realized.The stable rolling of hot-rolled ribbed steel bars with four slits has been achieved,ultimately leading to industrial mass production with an annual efficiency of 3.6 million Yuan and the product quality meets the needs of users.
