latest 2 roller rebar rolling machine uses: this kind of2 roller rolling machine is used to making different specification rebar. working principle of cold rolling mill: First reduces the diameter of the hot rolled wire steel bars, and then makes ribs on bars by cold rolling machine. specifications: There are three types : small type (mean the inletmaterial below10mm), medium-sized (mean theinlet material below Φ12mm), large type (mean theinlet material below Φ14mm)of cold rolling mills. the technical parameter of cold rolling mill: Project Technical parameter Unit Supplementary details Raw material Φ6-14 mm Roller diameter Φ228 mm Special-purpose alloy Equipped with power 75 KW YVP200-4 variable-frequency Variable-speed motor Gear center distance 228 mm Herringbone gear Rolling line speed max3 M/s Sheared length 1-12 m Flying shear 5.5 KW Product specification Φ5-12 mm Output 0.83-7.99 T/hour The final product are 2 ribbed or 3 ribbed deformed steel bar in circular shape or in line shape. This set of machine is automatic, only need two or three man, one is to control the synthetically control panel, the second is to weld steel coil and bundle the final productions.Do you have requirement about rolling line speed, power? They all related to the efficiency andproductivity you want. It would be kind if you tell me more detail information.The more information you give ,We wouldsupplypropermachine for you.
