Abstract：Pointing to some problems such as poor commonality of pass, more specifications of guide, high production cost and so on of rolling unit in Laiwu Steel’s high quality steel production line, a series of optimization and improvement measures were taken included optimizing and merging the K4 pass, making full use of roll gap adjustment, the commonality of the pass was increased and then the rollers needed by the K4 pass were merged to 5 sets from 8 sets; Choosing NiCr alloy material guide wheel with impact resistance and a large quantity of steel production, and incorporating adjacent specifications of guide wheels, the guide wheels were reduced to 27 kinds from 42. After the improvements, the production ran well, rolling the quantity of waste reduced by 73 t and the roll consumption of per ton steel decreased from 0.36 kg to 0.20 kg;At the same time, the quantity of spare parts was reduced, roll changing assembly time was saved and the labor intensity was reduced.
