Steel Strapping Production Machine

2.1 Highlights The strap of 930MPa is used to strapping products such as hot-rolled coil, cold-rolled coil, hot-dip-galvanizing coil, color-coating plate, stranded wire and so on. And the strap of 800MPa is used to strapping the products such as brick bat, metal component, glass plate, hard board, shaving board, timber and so on. The Production conforms to the standards of ASTM D-3953 EN13246; 2001 . The products have the excellent plasticity and meet requirement of manual, semi-Automatic and automatic strapping.The induction heating technology is adopted in the production line so that the strap can be heated up rapidly to refine crystal grain. The strap heat-treated can obtain the property of high yield strength and elasticity. At the same time it reduces the surface oxidation and surface bluing is fine.An unleaded heat-treating is implemented during the whole production process and prevents environment contamination caused by the heavy metal-lead. So the products made by the line meet the requirement of the RoHS standard of EU and can be exported safety.AC variable frequency speed control and PLC program control are adopted. Tension is controlled segmentally. According to the line speed, the closed-loop control of heating power is implemented. HMI is configured by touch screen of SIEMENS. 2.2 Raw MaterialThickness of steel strap, 0.6 1.0mm; Width of steel strap, <300mm; Coil weight, <2000kg;Steel grade, mild carbon steel(for 800MPa products) Low-alloy steel or medium-carbon steel (for 930MPa products) 2.3 Strap ProductThickness, 0.6 0.9mm; Width, 19, 25.4, 31.75mm; Coil weight, Ribbon wound 55±5kg; Oscillated wound 300±5kg; 2.4 main Line ComponentsUncoiler 1Welder (including grinding machine) 1 Cutter 1 Rotary shear 1 NO.1 looper(Accumulator) 1Edge treatment unit 1Bridle 5Medium frequency induction power supply unit 1 Medium frequency induction coils 1 Heat retaining furnace 1 Infrared thermometer 2 Cooling water tank 1 Dryer 4 Wax device 1 Paint System 1Induction Coils for paint drying 1Medium frequency induction coils 1NO.2 looper(Accumulator) 1 coiler(Ribbon and oscillated wound) 4 Coil weight, 55kg,300kg Electrical automatic control system 1 Operating pulpit 5 2.5 Time schedule of equipment manufacture, 5 months2.6 Engineering servicesIn order to supervise the erection and commissioning, we shall be responsible for sending skilled, healthy and competent technical personnel to your country for technical services and they will stay till the line output satisfactory products.
