style="text-indent:25px">鍍鋅管除銹方法：首先利用溶劑清洗鋼材表面，把表面的有機物去除，然后使用工具除銹（鋼絲刷）,去除松動或傾斜的規(guī)模，鐵銹，焊渣等,使用酸洗的方式。鍍鋅分為熱鍍和冷鍍，熱鍍不易生銹，冷鍍較易生銹。連接方式：鍍鋅鋼管連接方式：螺紋，焊接。滾槽方式連接，滾槽焊縫開裂將管口壓槽部分的內(nèi)壁焊筋磨平，減少滾槽阻力。調(diào)整鋼管與滾槽設(shè)備的軸心，并要求鋼管與滾槽設(shè)備水平。調(diào)整壓槽速度，壓槽成型時長不能超過規(guī)定，均勻、緩慢施力。滾槽鋼管斷裂，將鋼管管口壓槽部分內(nèi)壁焊筋磨平，減少滾槽阻力。</p><p

大跨度鋼橋構(gòu)件；6 船舶、機械制造框架結(jié)構(gòu)； 7 火車、汽車、拖拉機大梁支架；8 港口傳送帶、高速公路檔板支架。應(yīng)用軋制H型鋼的技術(shù)合理性：工業(yè)與民用建筑中采用H型鋼不但比常用工字鋼節(jié)省勞動力、降低成本，而且還可降低用鋼量。如廠房鋼結(jié)構(gòu)采用熱軋工字鋼與熱軋寬翼緣H型鋼的用鋼量相比較，可降低15%-20%。H型鋼在各個方向上都具有抗彎能力強、施工簡單、節(jié)約成本和結(jié)構(gòu)重量輕等優(yōu)點。</p><div
