鍍鋅扁鋼：鍍鋅扁鋼，是指寬12-300mm、厚4-60mm、截面為長方形并稍帶鈍邊的鍍鋅鋼材。鍍鋅扁鋼可以是成品鋼材，也可以做鍍鋅管的坯料和鍍鋅帶。 </p> <p> 主要用途 </p> <p> 鍍鋅扁鋼作為成材可用于制箍鐵、工具及機(jī)械零件，建筑上用作房架結(jié)構(gòu)件、扶梯。 </p> <p> 鍍鋅工藝熱鍍鋅也叫熱浸鋅和熱浸鍍鋅：是一種有效的金屬防腐方式，主要用于各行業(yè)的金屬結(jié)構(gòu)設(shè)施上。是將除銹后的鋼件浸入500℃左右融化的鋅液中，使鋼構(gòu)件表面附著鋅層，從而起到防腐的目的。熱鍍鋅工藝流程：成品酸洗-水洗-加助鍍液-烘干-掛鍍-冷卻-藥化-清洗-打磨-熱鍍鋅完工熱鍍鋅是由較古老的熱鍍方法發(fā)展而來的，自從1836年法國把熱鍍鋅應(yīng)用于工業(yè)以來，東川區(qū)鍍鋅扁鋼，已經(jīng)有一百四十年的歷史了，東川區(qū)鍍鋅扁鋼。然而，東川區(qū)鍍鋅扁鋼，熱鍍鋅工業(yè)是近三十年來伴隨冷軋帶鋼的飛速發(fā)展而得到了大規(guī)模發(fā)展。冷拔鋼也可以被稱為冷拉型鋼，也被稱為冷拉型鋼，也被稱為冷拉鋼。東川區(qū)鍍鋅扁鋼</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="東川區(qū)鍍鋅扁鋼,鍍鋅扁鋼" src="http://tyunfile.71360.com/UploadFile/ynmaoxuan/637203297971630860/2164909.jpg"></div><p> 鍍鋅扁鋼的施工注意事項 </p> <p> 經(jīng)過冷拔的處理加工工藝，可以使鋼材精度更高、表面質(zhì)量更好，但是隨著鍍鋅扁鋼生產(chǎn)工藝要求的越來越高，對鍍鋅扁鋼的質(zhì)量也越來越嚴(yán)苛，在生產(chǎn)中需要滿足一定的要求。 </p> <p> 為了保證開始拔制時芯棒能順利地被鍍鋅扁鋼帶入變形區(qū)，芯棒端面一般倒成45°角。使用圓錐形芯棒時，鍍鋅扁鋼管壁的變形主要在芯棒頂端進(jìn)行。 </p> <p> 因此對這種芯棒，正確選擇其定徑帶的長度及圓錐部分的錐角很重要。減壁量一定的情況下，錐角小則減壁區(qū)長，摩擦力增加，錐角大則變形集中，易加劇芯棒端部磨損且正壓力的水平分量增加。選擇錐角要綜合考慮各種因素的影響。一般錐角常用的是8～9。長芯棒直徑等于拔后管子內(nèi)徑，芯棒長度應(yīng)大于拔后管子長度。 </p> <p> <br />
