        鋼板鋼材預處理線

        鋼板鋼材預處理線

        鋼材預處理線主要由橫移上料機構、輸入輥道、預熱室、拋丸清理機、過渡輥道、噴漆機、烘干室、輸出輥道、橫移下料機構、除塵系統、漆霧處理系統、電氣等組成。
        輥道:全線設有橫移上料機構、輸入輥道、過渡輥道、室內輥道、輸出輥道、橫移下料機構組成,該系統均采用變頻調速,達到輸送工件之目的。
        預熱:該裝置有以下加熱形式:電遠紅外輻射式、蒸氣式、燃氣及燃油等加熱方式,使鋼材在拋丸清理前預熱溫度達到40-70℃。預熱熱是去除冰、寒冷和水濕的好方法。
        拋丸清理機:該要采用多臺先進的高效拋丸器,拋射出高速密集的彈丸打擊在工件表面上,將銹等污垢一掃而光,獲得一定粗糙度的光潔表面,提高漆膜與工件表面的附著力。
        噴漆:該系統主要由噴漆室、上下噴漆小車、傳動機構、測高系統、氣控系統、高壓無氣噴漆泵及管路等級成。
        烘干:烘干室與噴漆室連接貫通,噴漆后的工件在烘干室內由板鏈輸送進行烘干,保證工件下表面漆膜的完好,使工件達到漆膜指干要求。
        漆霧處理:該系統可分為干式或濕式漆霧處理方式,經處理后的氣體高空排放,排放三苯有機溶劑氣體的濃度達到國家環保排放標準要求。
        電氣:全線電氣控制系統采用PLC可編程序控制器,分手動、自動兩種控制方式。
        A rolled steel pretreating line usually consists of specially engineered conveyor systems, a pre-heater, a inlet rollgang, middle rollgang, shot blast machine, an automatic paint spray system, a subsequent dryer, outlet rollgang, dust removing system, paint &fog treating system and the electric system.
        Rollgang:The total line contains the feeding device, inlet rollgang, middle rollgang, inner room rollgang, outlet rollgang and expulsing rollgang, which are all under frequency speed controlled.
        Pre-Heater:It makes the rolled steel to reach the temperature of 40~70℃ before the shot blasting. Heat is good against ice, cold and wetness. It prevents moisture from getting into the blast media.
        Shot Blasting Machine:It is equipped with several high-tech impeller heads, which blast high speed shots to the surface of the workpiece. Rust and scale disappear in no time! and the surface will gain a clean surface with a certain rough level.
        Painting Line:The system is arranged with painting room, up and down spraying cars, conveyor, height measuring system, gas controlling system, high pressure none air spraying pump and pipes.
        Paint Dryer:The drying takes place on a continuous basis in many variations: In front or behind the paint booth, heated by gas, oil or electric, with special overspray extraction zones and cooling zones.It makes the drying effect to reach the customer’ s request.
        Paint&fog Treatment:This system contains the dry and the wet paint processing mode. Through the upper air emissions after the processing, the density of the tritan organic solution reaches the national environmental protection emission standard.
        Electric System:The PLC programmable controller contains manual and automatic mode.
