Production process
Laying the double-side copper coated steel strip which is made of low carbon gapless atom steel (Steel strip material is BHG2) on uncoiler, than rolling 720℃ on forming to be double layers roll welding tube, send into brazing furnace and welding with protective gas, next cooling in sealed cooling with protective gas,next cooling in sealed cooling with protective gas and slow-cooling in sealed cooling with protective gas and slow-cooling in sealed cooling with protective gas and slow-cooling, spraying directly by emulsion water than drying.At last coiling and packing
Capacity
Totally power 83.6KW, main transformer power:75KW
Machine length:30 M (recommend workshop:60m)
Average welding speed ( according Φ4.76*0.7) 20-22m/min
Next： ZT 8-pipe electrolytic zinc and copper coating production line
