1250mm High Output Hot Dip Continuous Galvalume Line
hot dip continuous galvalume line
1.description for the hot dip galvalume line:
This kind of strip has excellent corrosion resistance and it is used widely in the world, it replace galvanized strip. Aluminium strip has merits of corrosion resistance of air and oxidation resistance, the galvanized strip has the merits of electrochemical protection. GL strip has merits of aluminium strip and galvanized strip.
2.Technology Parameter for the hot dip galvalume line:1)process method:American- steel – union2)material: cold rolled carbon structure steel, qualified carbon structure steel and low alloy steel roll3)steel type: 08AL,SPCC,SPCD ,SPCE4)layer condition: normal spangle, small spangle, skin pass spangle5)layer weight: GI:B/T2518-886)thickness range(two side): 120g/m27)layer control method: air knife8)treatment after galvanized: skin pass, stretch, anti-fingerprint coating/chromate coating9)continuous annealing furnace: horizontal/vertical , electricity, natural gas, coal gas, etc10)zinc pot: main frequency induction heating ceramic zinc pot11)skin pass: four-tandem, bottom support roller AC frequency driving12)tension leveler: single bending & single stretching /double bending & single stretching/two bending & 13)two stretching, elongation among 0.5~2.0%14)driving control: main drive adopt SIEMENS AC complexor frequency control system15)quality standard: GI:B/T2518-2004 Process Flow for the hot dip galvalume line:Manually loading →entry coil car → No.1,No2 pay-off reel →No.1,No.2 double-rolls pinch →No1,No.2 shears → welder →No.1 bridle roll →No.1 entry looper →No.1 CPC →
