Production Facility of gi metal sheet
Process of gi metal sheet
Pay off reel → double cut shear → welder-notcher → entry accumulator → pre cleaning section → furnace → hot bridle → zinc pot → air knife → after cooler → water quench → dryer → skin pass mill → dryer → tension leveler → dryer → chemical coater → chemical oven → cooler → exit accumulator → oiler → exit shear → tension reel.
Surface Treatment of gi metal sheet
Surface Treatment |
Features |
Chemical passivating treatment |
minimize the chance of white rust froming during transit and strorage |
maintain the bright, shiny appearance for a longer time |
|
Oils |
minimize the tendency for storage and transit stain |
Passivating oils |
provide the protection from storage and transit stain by special chemcials called corrosion inhibitors |
