一、球墨鑄鐵的概念球墨鑄鐵是通過(guò)球化和孕育處理得到的球狀石墨，有效地提高了鑄鐵的機(jī)械性能，特別是提高了塑性和韌性，從而得到比碳鋼還高的強(qiáng)度。球墨鑄鐵是20世紀(jì)五十年代發(fā)展起來(lái)的一種**度鑄鐵材料，其綜合性能接近于鋼，正是基于其優(yōu)異的性能，已成功地用于鑄造一些受力復(fù)雜，強(qiáng)度、韌性、耐磨性要求較高的零件。球墨鑄鐵已迅速發(fā)展為僅次于灰鑄鐵的、應(yīng)用十分***的鑄鐵材料。所謂“以鐵代鋼”，主要指球墨鑄鐵。二、成分生鐵是含碳量大于2％的鐵碳合金，工業(yè)生鐵含碳量一般在，并含C、SI、Mn、S、P等元素，是用鐵礦石經(jīng)高爐冶煉的產(chǎn)品。根據(jù)生鐵里碳存在形態(tài)的不同，又可分為---煉鋼生鐵、鑄造生鐵和球墨鑄鐵等幾種。析出的石墨呈球形的鑄鐵。球狀石墨對(duì)金屬基體的割裂作用比片狀石墨小，使鑄鐵的強(qiáng)度達(dá)到基體組織強(qiáng)度的70～90％，抗拉強(qiáng)度可達(dá)120kgf/mm2，并且具有良好的韌性。球墨鑄鐵除鐵外的化學(xué)成分通常為：含碳量～％，含硅量～％，含錳、磷、硫總量不超過(guò)％和適量的稀土、鎂等球化劑。三、性能球鐵鑄件差不多已在所有主要工業(yè)部門中得到應(yīng)用，這些部門要求高的強(qiáng)度、塑性、韌性、耐磨性、耐嚴(yán)重的熱和機(jī)械沖擊、耐高溫或低溫、耐腐蝕以及尺寸穩(wěn)定性等。</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。阿克蘇球墨鑄鐵搶修節(jié)直銷。</p><div
