unit characteristic
1/ function completeness, meet various requirements
3.        adopt radianttube heating technology, heating evenly control simple, good stripshape, adopt mild type fibre inner lining, have the feature of fastfurnace building, light thermal lag
4.        set cleaningsection, adopt advanced applied integrated technology of chemicaldegreasing and electrolytic degreasing, improve the effect ofdegreasing , clean surface oil and ferrous powder
5.        adopt protectivegas circulate spray installation in strip cooling, adopt frequencyadjusting, cooling speedy fast and even, precisely control thetemperature when the strip into the zinc pot, effectively better upthe strip shape and surface quality
6.        adopt incinerator& heat recovery technology, heating to the degreasing liquidand provide drying hot air, improve hot energy utilization ratio,reduce unit running cost
7.        adopt pre zincpot and main pot method, zinc liquid mixing evenly, long life
