補(bǔ)焊球墨鑄鐵時(shí)，熔合區(qū)也會(huì)產(chǎn)生白口，焊縫產(chǎn)生剝離、裂紋的傾向也很大。為了防止剝離，應(yīng)采用嚴(yán)格的電弧冷焊工藝。鎳鐵焊條只能補(bǔ)焊要求不高的球墨鑄鐵。高釩焊條冷焊后接頭加工性較差，但是，如果操作工藝得當(dāng)，也能得到較為理想的加工性。對(duì)球墨鑄鐵毛坯件，應(yīng)先進(jìn)行熱處理，消除鑄造應(yīng)力以后再進(jìn)行焊接，可以有效防止裂紋，焊后可不必進(jìn)行消除應(yīng)力退火。3.球墨鑄鐵氣焊氣焊時(shí)的加熱速度和冷卻速度比較緩慢、均勻，可以有效防止白口、裂紋。氣焊熱源溫度較低，球化元素蒸發(fā)、氧化燒損較少，容易實(shí)現(xiàn)球化。氣焊火焰通常采用中性焰或弱還原焰。為了保證焊縫具有適量的球化元素殘留量，以便實(shí)現(xiàn)焊縫石墨球化，焊絲中的球化元素應(yīng)較球墨鑄鐵通常球化元素殘留量高一些。球墨鑄鐵氣焊用焊絲型號(hào)用RZCQ表示，成分見(jiàn)表15-11。由表15-11可以看出，RZCQ-1的Mn、S、P含量比RZCQ-2低很多，且C和Si的含量也較后者低。氣焊球墨鑄鐵一般是在球鐵清砂后發(fā)現(xiàn)缺點(diǎn)的情況下進(jìn)行，補(bǔ)焊后對(duì)工件再進(jìn)行退火處理，RZCQ-1焊絲的成分有利于提高焊縫的塑性和韌性。因此，該焊絲適用于鐵素體球鐵的焊接。球鐵氣焊用火焰性質(zhì)及熔劑與灰鑄鐵氣焊相同。退火處理后，整個(gè)焊接接頭為鐵素體組織。</p><p> **近有輸水管道業(yè)內(nèi)人士傳給我一份新興鑄管寫(xiě)的《球管與鋼管的技術(shù)比較》，期間我還在網(wǎng)上看了兩個(gè)新興鑄管的PPT，《球墨鑄鐵管與鋼管比較》和《球管以PCCP管的比較》。本來(lái)認(rèn)為這些材料是企業(yè)的市場(chǎng)宣傳，管道工程技術(shù)人員在設(shè)計(jì)管道時(shí)會(huì)理性判斷，正確加以選擇。其實(shí)不然，很多業(yè)內(nèi)專業(yè)人士甚至認(rèn)可這其中的觀點(diǎn)，因此，本人認(rèn)為有必要與新興鑄管商榷，澄清幾個(gè)有關(guān)的說(shuō)法和問(wèn)題。1?球墨鑄鐵管在歐美地區(qū)使用比例達(dá)到90%以上輸水鋼管在北美使用超過(guò)160年，1858年***條輸水鋼管安裝在加州當(dāng)時(shí)的淘金地區(qū)，這條水管用鉚接鋼管制成，直徑為280－560mm，壁厚。這條輸水鋼管一直使用到1970年代，壽命超過(guò)100年。***條焊接輸水鋼管于1926年生產(chǎn)，管道長(zhǎng)近130Km，管徑1549－1651mm，當(dāng)時(shí)由加州東灣水務(wù)局安裝在莫?jiǎng)P勒米水道。到了1940年，美國(guó)大概安裝有5630Km長(zhǎng)的輸水鋼管。1970年代有差不多8850Km長(zhǎng)的輸水鋼管在使用。北美大口徑輸水管道市場(chǎng)主要是由螺旋焊管提供，其它還包括鋼筒混凝土壓力管（PCCP），球墨鑄鐵管的份額很少。球墨鑄鐵管通常在DN600或DN800以下口徑相對(duì)鋼管有成本優(yōu)勢(shì)，因此口徑超過(guò)DN1000以上的球墨鑄鐵管在歐美國(guó)家很少。阿勒泰離心球墨鑄鐵管推薦。</p><div

降低殘留鎂量(<007%)；采用稀土鎂合金來(lái)處理，稀土氧化物殘余量控制在002%～004%。(2)工藝設(shè)計(jì)要確保鑄件在凝固中能從冒口不斷地補(bǔ)充高溫金屬液，冒口的尺寸和數(shù)量要適當(dāng)，力求做到順序凝固。(3)必要時(shí)采用冷鐵與補(bǔ)貼來(lái)改變鑄件的溫度分布，以利于順序凝固。(4)澆注溫度應(yīng)在1300～1350℃，一包鐵液的澆注時(shí)間不應(yīng)超過(guò)25ｍｉｎ，以免產(chǎn)生球化衰退。(5)提高砂型的緊實(shí)度，一般不低于90；撞砂均勻，含水率不宜過(guò)高，保證鑄型有足夠的剛度。2夾渣(1)硅：硅的氧化物也是夾渣的主要組成部分，因此盡可能降低含硅量。(2)硫：鐵液中的硫化物是球鐵件形成夾渣缺點(diǎn)的主要原因之一。硫化物的熔點(diǎn)比鐵液熔點(diǎn)低，在鐵液凝固過(guò)程中，硫化物將從鐵液中析出，增大了鐵液的粘度，使鐵液中的熔渣或金屬氧化物等不易上浮。因而鐵液中硫含量太高時(shí)，鑄件易產(chǎn)生夾渣。球墨鑄鐵原鐵液含硫量應(yīng)控制在006%以下，當(dāng)它在009%～0135%時(shí)，鑄鐵夾渣缺點(diǎn)會(huì)急劇增加。(3)稀土和鎂：近年來(lái)研究認(rèn)為夾渣主要是由于鎂、稀土等元素氧化而致，因此殘余鎂和稀土不應(yīng)太高。(4)澆注溫度：澆注溫度太低時(shí)，金屬液內(nèi)的金屬氧化物等因金屬液的粘度太高，不易上浮至表面而殘留在金屬液內(nèi)；溫度太高時(shí)。阿克蘇球墨鑄鐵搶修節(jié)規(guī)格。頭屯河區(qū)球墨鑄鐵管要多少錢</p><p
