熱鍍鋅圓鋼長度尺寸是各種鋼材的基本尺寸，是指鋼材的長、寬、高、直徑、半徑、內徑、外徑以及壁厚等長度。其中熱鍍鋅圓鋼的范圍定尺是節(jié)省材料的一種有效措施，就是長度或長乘寬不小于某種尺寸，或是長度、長乘寬從多少到多少的尺寸范圍內交貨。 </p> <p> 凡熱鍍鋅圓鋼的尺寸在標準規(guī)定范圍內，而又不要求固定尺寸的稱之為不定尺，又可以被稱為通常長度，按不定尺交貨的金屬材料，只要在規(guī)定長度范圍內交貨就可以了。熱鍍鋅圓鋼定尺按訂貨要求切成固定尺寸的稱為定尺。按定尺長度交貨時，所交金屬材料必須具有需方在訂貨合同中指定的長度。昆明鍍鋅圓鋼規(guī)格齊全鍍鋅圓鋼一般指建筑安裝時用在避雷接地的接線，用普通圓鋼（通常為直徑8mm至12mm）經(jīng)電鍍鋅保護層得到。</p><div

線內退火就是由冷軋或熱軋車間直接提供帶卷作為熱鍍鋅的原板，在熱鍍鋅作業(yè)線內進***體保護再結晶退火。屬于這個類行業(yè)的熱鍍鋅方法包括：森吉米爾法、改良森吉米爾法、美鋼聯(lián)法(同日本川崎法)、賽拉斯法、莎倫法。 </p> <p> 森吉米爾法 </p> <p> 它是把退火工藝和熱鍍鋅工藝聯(lián)合起來，其線內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，森吉米爾法產量高、鍍鋅質量較好，此法曾得到廣泛應用。 </p><p>

style="text-indent:25px">鍍鋅圓鋼為什么能作為暗裝避雷帶使用？五華區(qū)鍍鋅圓鋼</p><p 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力小，而其它鋼筋與混凝土的粘結力大。 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。圓鋼應用前景廣闊，被普遍用于五金，建筑，汽車、造船、石化、機械、醫(yī)藥、食品、電力、能源、航天等、建筑裝潢。相當普遍的普通機械零件加工，一般的桿類鋼件，CD桿、螺栓、螺母。五華區(qū)鍍鋅圓鋼</p><p
