它是把退火工藝和熱鍍鋅工藝聯(lián)合起來，其線內(nèi)退火主要包括氧化爐，還原爐兩部份組成。帶鋼在氧化爐中煤氣火焰直接加熱到450度左右，把帶鋼表面殘存的軋制油燒掉，凈化表面。后再把帶鋼加熱到700-800度完成再結(jié)晶退火，經(jīng)冷卻段控制進鋅鍋前溫度在480度左右，在不接觸空氣的情況下進入鋅鍋鍍鋅，因此，森吉米爾法產(chǎn)量高、鍍鋅質(zhì)量較好，此法曾得到廣泛應用。昆明質(zhì)量鍍鋅圓鋼生產(chǎn)廠家鍍鋅圓鋼，云南貿(mào)軒商貿(mào)有限公司。</p><div

<p> 化學成分：C0.42-0.50Si0.17-0.37Mn0.50-0.80Cr不大于0.25Ni不大于0.30Cu不大于0.25力學性能：抗拉強度不小于600Mpa，屈服強度不小于355Mpa，延伸率不小于16，斷面收縮率不小于40%，沖擊功不小于31J。未熱下HBS10/3000不大于229.推薦熱處理溫度：正火850攝氏度。淬火840攝氏度，回火600攝氏度。 </p> <p> 鍍鋅圓鋼的鍍鋅層均勻沒有漏鍍的地方，沒有鋅疙瘩，鍍鋅層應該符合相應國家標準要求，如鋅層不小于250克/平米，鍍鋅層厚度的大小直接決定圓鋼防腐蝕能力 </p> <p> <br /> </p><p> 鍍鋅圓鋼為什么能作為暗裝避雷帶使用？ </p> <p> 暗敷在屋頂混凝土中的避雷帶沒有必要用鍍鋅圓鋼，直接采用結(jié)構(gòu)用的鋼筋即可。 </p> <p> 一般設(shè)計要求采用鍍鋅圓鋼是明敷的避雷帶。因此鍍鋅圓鋼與結(jié)構(gòu)鋼筋除了防銹功能外沒有可以對比的地方。 </p> <p> 因為空氣中有一定的酸性，普通鋼鐵容易腐爛，鍍鋅的就不易腐爛生銹，所以為了延長使用壽命，暴露在外的構(gòu)件一般都采用鍍鋅，包括鋼管。而砼里面的鋼筋由于有保護層，所以沒必要采用鍍鋅了。云南貿(mào)軒商貿(mào)有限公司。鍍鋅圓鋼的生產(chǎn)制造有什么質(zhì)量要求？</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">圓鋼與其它鋼筋的區(qū)別：1、外型不一樣，圓鋼外型光圓，無紋無肋，其它鋼筋表面外型有刻紋或有肋.這樣就造成圓鋼與混凝土的粘結(jié)力小，而其它鋼筋與混凝土的粘結(jié)力大。2、成份不一樣，圓鋼(一級鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。3、強度不一樣.圓鋼強度低，其它鋼強度高，即直徑大小相同的圓鋼與其它鋼筋相比，圓鋼所能承受的拉力要比其它鋼筋小，但圓鋼的塑性比其它鋼筋強，即圓鋼在被拉斷前有較大的變形，而其它鋼筋在被拉斷前的變形要小得多。鍍鋅圓鋼的材質(zhì)分類有哪些及熱處理溫度是多少？昆明質(zhì)量鍍鋅圓鋼生產(chǎn)廠家</p><p
