cold rolling machine is a new type of steel bar cold rolling processing equipment. The machine can process hot-rolled wire rods and hot-rolled coils with diameters between 6.5 mm and 12 mm into cold-rolled ribbed steel bars with finished product diameters between 5 mm and 12 mm. The cold-rolled ribbed steel bar rolled by the cold-rolling machine is an updated product of cold-drawn low-carbon steel wire in the prestressed concrete member. In the cast-in-place concrete structure, it can replace the first-class steel bar to save steel. It is a better kind of cold-worked steel. If speed regulation is not required during the rolling process of the  cold rolling machine  , an AC motor can be used; if speed regulation is required during the rolling process of the cold rolling machine , a DC motor can be used.
