熱鍍鋅方管和冷鍍鋅方管的區別
鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)方(fang)管(guan)是一(yi)種具以熱(re)軋(ya)(ya)或冷(leng)軋(ya)(ya)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)帶鋼(gang)或鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)卷板為(wei)坯料經(jing)冷(leng)彎(wan)曲加工(gong)成(cheng)型后再經(jing)高(gao)頻焊(han)接制(zhi)成(cheng)的方(fang)形(xing)截(jie)(jie)面形(xing)狀尺寸的空(kong)心方(fang)形(xing)的截(jie)(jie)面型鋼(gang)鋼(gang)管(guan)，或將事先(xian)做好(hao)的冷(leng)彎(wan)空(kong)心型鋼(gang)管(guan)再經(jing)熱(re)浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)加工(gong)而成(cheng)的鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)方(fang)矩管(guan)。鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)方(fang)管(guan)從生產工(gong)藝(yi)上是分為(wei)熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)方(fang)管(guan)和冷(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)方(fang)管(guan)的。正是由于這兩種鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)方(fang)管(guan)的加工(gong)不相同(tong)也就造就了(le)它們很多不同(tong)
