钢板钢材预处理线

钢板钢材预处理线

钢板钢材预处理线

钢材预处理线主要由横移上料机构、输入辊道、预热室、抛丸清理机、过渡辊道、喷漆机、烘干室、输出辊道、横移下料机构、除尘系统、漆雾处理系统、电气等组成。
辊道:全线设有横移上料机构、输入辊道、过渡辊道、室内辊道、输出辊道、横移下料机构组成,该系统均采用变频调速,达到输送工件之目的。
预热:该装置有以下加热形式:电远红外辐射式、蒸气式、燃气及燃油等加热方式,使钢材在抛丸清理前预热温度达到40-70℃。预热热是去除冰、寒冷和水湿的好方法。
抛丸清理机:该要采用多台先进的高效抛丸器,抛射出高速密集的弹丸打击在工件表面上,将锈等污垢一扫而光,获得一定粗糙度的光洁表面,提高漆膜与工件表面的附着力。
喷漆:该系统主要由喷漆室、上下喷漆小车、传动机构、测高系统、气控系统、高压无气喷漆泵及管路等级成。
烘干:烘干室与喷漆室连接贯通,喷漆后的工件在烘干室内由板链输送进行烘干,保证工件下表面漆膜的完好,使工件达到漆膜指干要求。
漆雾处理:该系统可分为干式或湿式漆雾处理方式,经处理后的气体高空排放,排放三苯有机溶剂气体的浓度达到国家环保排放标准要求。
电气:全线电气控制系统采用PLC可编程序控制器,分手动、自动两种控制方式。
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.
