熱鍍鋅方管和冷鍍鋅方管的區別
鍍(du)(du)(du)鋅(xin)(xin)(xin)方管(guan)是(shi)一種(zhong)具以熱(re)軋(ya)(ya)或(huo)冷(leng)軋(ya)(ya)鍍(du)(du)(du)鋅(xin)(xin)(xin)帶鋼或(huo)鍍(du)(du)(du)鋅(xin)(xin)(xin)卷板(ban)為坯料經(jing)冷(leng)彎曲加(jia)(jia)工(gong)成型(xing)后(hou)再(zai)經(jing)高頻焊接制成的(de)方形截(jie)面形狀尺寸的(de)空心(xin)方形的(de)截(jie)面型(xing)鋼鋼管(guan)，或(huo)將(jiang)事先做(zuo)好(hao)的(de)冷(leng)彎空心(xin)型(xing)鋼管(guan)再(zai)經(jing)熱(re)浸(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)加(jia)(jia)工(gong)而(er)成的(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)方矩管(guan)。鍍(du)(du)(du)鋅(xin)(xin)(xin)方管(guan)從(cong)生(sheng)產工(gong)藝上是(shi)分為熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)方管(guan)和冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)方管(guan)的(de)。正是(shi)由于這兩種(zhong)鍍(du)(du)(du)鋅(xin)(xin)(xin)方管(guan)的(de)加(jia)(jia)工(gong)不相同(tong)(tong)也就造就了它們(men)很多(duo)不同(tong)(tong)
