class="khcont">隨著我們的科技發(fā)展加快，我們對我們的歷史慢慢的忘掉，可是球墨鑄鐵的歷史大家多少，球墨鑄鐵是20世紀五十年代發(fā)展起來的一種高強度鑄鐵材料，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雜，強度、韌性、耐磨性要求較高的零件。接下來我們一起了解下關(guān)于球墨鑄鐵的歷史有哪些。<br /> 國內(nèi):在河南鞏縣鐵生溝西漢中、晚期的冶鐵遺址中出土的鐵?，而現(xiàn)代的球墨鑄鐵則是遲至1947年才在國外研制成功的。我國古代的鑄鐵，在一個相當長的時期里含硅量都偏低，也就是說，在約2000年前的西漢時期，中國鐵器中的球狀石墨，就已由低硅的生鐵鑄件經(jīng)柔化退火的方法得到。這是中國古代鑄鐵技球墨鑄鐵技術(shù)的重大成就，也是世界冶金史上的奇跡。<br /> 1981年，中國球鐵專家采用現(xiàn)代科學手段，對出土的513件古漢魏鐵器進行研究，通過大量的數(shù)據(jù)斷定漢代中國就出現(xiàn)了球狀石墨鑄鐵。有關(guān)論文在第18屆世界科技史大會上宣讀，轟動了國際鑄造界和科技史界。國際冶金史專家于1987年對此進行驗證后認為:古代中國已經(jīng)摸索到了用鑄鐵柔化術(shù)制造球墨鑄鐵的規(guī)律，這對世界冶金史作重新分期劃代具有重要意義。<br /> 國外法國的雷奧姆爾(Reaumur)于1722年i制成了自心可鍛鑄鐵。后來、美國的塞斯·包伊登(Seth·Boyden)于1826年發(fā)明了黑心可鍛鑄鐵。<br /> 到了二十世紀二十年代。由于對鑄鐵中碳、硅等主要成分及加入其他合金元素的影響、熔化方法、孕育效果等方面的研究并有了進展，出現(xiàn)了所謂高級鑄鐵。因此，材質(zhì)有了相當可觀的改善，并在一定程度上擴大了應用范圍。但是，由于存在著韌性低這樣的根本缺點，未能迅速擴大其應用范圍。</div><p><img

class="khcont5">球磨鑄鐵管市場供需形勢有望繼續(xù)改善。加之政策層面依然有進一步出臺寬松政策的預期，有利于市場情緒進一步向好。預計4月份國內(nèi)鋼價總體將呈震蕩盤升走勢。市場在此前連續(xù)拉漲情況下仍需要休整，除特高壓對應高電壓等級變壓器廠家外，多數(shù)下游廠家由于整體經(jīng)濟不景氣，經(jīng)營情況不容樂觀，對降成本、保利潤的要求仍比較高，對取向硅鋼壓價也較為明顯。同時，取向硅鋼上下游企業(yè)資金鏈比較緊，占用資金量大，也帶來一定的負面影響。球磨鑄鐵管部分企業(yè)采購熱情不高，仍處于庫存消化周期。<br /> 目前，鋼市處于淡季，加上即將到來的年末是鋼廠和代理商商談新一年合同的時期，在社會庫存連續(xù)下降的情況下，鋼廠方面的合同組織壓力將加大，而且由于近來出口情況轉(zhuǎn)差，在銷售壓力增大的情況下，鋼廠方面可能會對鋼貿(mào)商擴大優(yōu)惠幅度。今年第四季度，大規(guī)模的冬儲難以出現(xiàn)，鋼貿(mào)商“蓄水池”功能將進一步減弱，鋼廠方面庫存和銷售壓力將進一步加大，預計整體鋼價受此影響將持續(xù)承壓。由于帶鋼市價整體走勢依然看跌較多，且從事銷售利潤難以有保證，導致商家采購帶鋼較為謹慎，帶鋼市場低庫存現(xiàn)象將繼續(xù)存在。據(jù)采訪部分商家和下游企業(yè)獲悉：今冬依然要冬儲，要看市場價格走勢而定;以當前市價走勢來看，近期不會做帶鋼冬儲。大部分商家認為：今年帶鋼冬儲將會延后到春節(jié)前一個月左右進行，受今年年初價格大幅下跌影響，今年冬儲量將比去年要少。</div><p><img

磨割法切割球墨鑄鐵管，就是用砂輪不斷的對球墨鑄鐵管進行磨切，直至斷裂。使用磨割的方法切割球墨鑄鐵管，首先要對切割部位進行劃線處理，以免在切割時出現(xiàn)偏差。將畫好線的球墨鑄鐵管放在切割機中，并對球墨鑄鐵管進行固定，用內(nèi)置的夾子夾緊。接下來啟動切割機，逐漸對切割機的手柄施加壓力，是砂輪切入球墨鑄鐵管中，直到球墨鑄鐵管截斷。在對手柄施加壓力時，不可一次用力過猛，否則會造成砂輪破裂。在機器運轉(zhuǎn)的時候，操作人員切不可站在有砂輪的一側(cè)，以免出現(xiàn)意外事故。當砂輪在切割時，出現(xiàn)震動、搖晃、不平穩(wěn)的現(xiàn)象，就要立刻停止操作，檢查砂輪是否出現(xiàn)缺口、破損，如果有必須及時更換，保證、正常的使用。切割好的球墨鑄鐵管的切面，如果有妨礙使用的毛刺，可以用砂輪或者銼刀進行加工磨平。</div><p><img

今日鋼坯走穩(wěn)，期螺小幅收跌，球墨鑄鐵管廠穩(wěn)中多偏弱。今日全國市場依舊偏弱，年后行情低迷難改，各地部分鋼廠仍未開工收貨，小廠開工率低，商家也不急于返市。目前在收鋼廠壓價意愿明顯，商家實際成交較少多以詢價為主，短期市價比較混亂，低價多交易少，預計短期廢鋼無止跌反彈可能。雖當前市場悲觀氛圍較濃，但商家還是對后市反彈還是抱有希望的，只不過今年廢鋼市場的回暖可能要比往年來的要晚，反彈空間暫時看弱。<br /> 國內(nèi)鋼市轉(zhuǎn)跌，主要成品材價格相繼走弱，與上游鋼坯價格在低位的上拉不同，成品材市場在庫存上升、需求疲弱、人氣不旺以及無資金推動的影響下，整體操作較蠃弱，價格下行，部分調(diào)整力度有所加速。而在鋼價一路下滑態(tài)勢下，原料價格也整體調(diào)低，成本重心攤薄，供需失衡、競爭加劇以及行業(yè)性發(fā)展瓶頸階段，成本的下移將進一步降低成品材價格的重心，繼續(xù)擠壓并倒逼市場加速調(diào)整。而資金的缺失則將成為經(jīng)濟發(fā)展寬松貨幣政策開啟下難以享受相應福利，市場需要真正的供需改觀來推動并扭轉(zhuǎn)?？偟脕砜矗瑖鴥?nèi)鋼市并未擺脫低位困境，市場所謂的新常態(tài)或許可以理解為低價新常態(tài)。當天整體球墨鑄鐵管廠未受利好影響，價格仍小幅下跌。具體來看，如建材市場出現(xiàn)北材低價現(xiàn)象，特別是兩會在北京召開，對終端用戶的施工影響不??；板材冷熱軋涂鍍市場則意在消化庫存，價格弱勢調(diào)整。據(jù)了解唐山目前正面臨減鋼產(chǎn)能的考驗，一定程度上也挫傷了市場信心，多數(shù)商家對廢鋼行情不看好，但小編認為機遇與苦難并存，商家應咬緊牙關(guān)共同度過廢鋼的低潮期迎來春天。</div><p><img
