PRODUCTION LINE OF FLUX-CORED WIRE Flux-cored wire is the fourth generation of advanced welding material which is developed in recent years. Compared with other welding materials, the flux-cored wire has the following advantages: high efficiency, excellent technology, little spatter, high welding quality, and convenient for automation. It is widely used in industrial developed countries. Manufacturing techniques of the flux-cored wire are: 1. Primary techniques mainly include roll forming of steel stripe, drawing, and sinking. 2. Rolling and sinking techniques are the primary. Drawing technique is used to adjust the diameter and ovality of the welding wire (applicable for the production of flux-cored wire, such as stainless steel with high fill rate and hard facing). The former is a mature manufacturing technique while the latter simply depends on roll forming and sinking. Some techniques are not perfect, and improving the production capacity encounters difficulties. Therefore, the production line of cold rolling and drawing of steel strip is the appropriate. According to requirements of the market, the company has developed flux-cored wire production lines for marine, steel structures, hard facing, and stainless steel to meet requirements of customers. Flux-cored wire production line is composed of: 1. Steel strip pay-off and take-up machine: Pay off the strip→ (welding) → dancer →steel strip take up (φ630 800 bobbin stripe take-up machine); 2. Preparation: Damping stripe pay-off machine → ultrasonic wave washing and rinsing machine→ Drying machine 3. Roll forming machine: roll into U type + power delivery device + roll into O type; 4. Rough drawing unit: 560 take-up machine; 5. Fine drawing machine: Bobbin pay-off machine Automatic damping dancer → 400 straight-line drawing machine →Dancer →Polishing machine→ Driving machine →bobbin take-up machine (φ630 800 bobbin wire take-up machine); 6. : automatic wire pay-off machine with constant tension controlled by inverter → Dancer → wire layer winding machine; The production line is applicable for the flux-cored welding wire. Diameter of the finished product: 0.8 2.0. STEEL STRIP PAY-OFF AND TAKE-UP MACHINES The machine is used in the paying off of disk-type steel strip during the production of flux-cored welding wire. Advantages are: 1.The horizontal design of disk type steel strip is convenient for the craning of steel strip; 2.Pneumatic tension device is convenient for the positioning of steel strip; 3.Automatic pay-off following up is used to ensure stable pay-off tension and can be used together with the strip take-up and pay-off machine.
