[0002] Cold rolling mill 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 finished cold-rolled ribbed steel bars with diameters between 5 mm and 12 mm. Cold-rolled ribbed steel bars rolled by cold rolling mill are the replacement products of cold-drawn low-carbon steel wires in prestressed concrete components.
