給水球墨鑄鐵管和排水球墨鑄鐵管的材質(zhì)為灰鑄鐵，由于給水球墨鑄鐵管需要承受壓力，常用HPT200,HT250灰鑄鐵，排水球墨鑄鐵管常用HT150以下的灰球墨鑄鐵管，給水球墨鑄鐵管都采用離心澆筑，鐵管外表光滑，如是承插式球墨鑄鐵管，則承**深，管壁也較厚，單根管長(zhǎng)度為6米。排水球墨鑄鐵管有些采用立模澆注，或小型離心澆注機(jī)鑄造，鐵管外表較粗糙，單根管長(zhǎng)度為3米，承口較淺，管壁較薄，給水球墨鑄鐵管分為工作壓力0.45MPA的低壓管，0.75MPA的中壓管，1.0MPA的高壓管，出廠前都需要按規(guī)范進(jìn)行水壓試驗(yàn)，合格后方可出廠，排水球墨鑄鐵管只作外觀檢查和敲一敲聽音檢查，無氣孔，裂縫和破損音響為合格。

球墨鑄鐵由於其糊狀凝固的特徵決定所生產(chǎn)的鑄鐵由於補(bǔ)縮不好經(jīng)常產(chǎn)生縮孔、縮松等缺點(diǎn)，為了能在鑄件生產(chǎn)以前預(yù)測(cè)這些缺點(diǎn)情況，早在印年代國(guó)內(nèi)外就開展了鑄造過程數(shù)值類比。鑄造過程數(shù)值類比是使用數(shù)值類比技術(shù)，在計(jì)算機(jī)虛擬的環(huán)境下類比實(shí)際鑄件形成過程，包括金屬液體的充型過程、冷卻凝固過程、應(yīng)力形成過程、判斷成型過程中主要原素的影響程度，預(yù)測(cè)**、性能和可能出現(xiàn)的缺點(diǎn)，為優(yōu)化工藝減少?gòu)U品提供依據(jù)。節(jié)能要求導(dǎo)致基本上重新設(shè)計(jì)零件，以達(dá)到重量輕、效率高，這就必然要提醒設(shè)計(jì)者集中注意材料。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">球墨鑄鐵是20世紀(jì)五十年代發(fā)展起來的一種**度鑄鐵材料，其綜合性能接近于鋼，正是基于其優(yōu)良的性能，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*次于灰鑄鐵的、應(yīng)用十分廣的鑄鐵材料。所謂“以鐵代鋼”，主要指球墨鑄鐵。球墨鑄鐵是通過球化和孕育處理獲得球狀石墨，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，從而取得比碳鋼還高的強(qiáng)度。球墨鑄鐵除鐵外的化學(xué)成分通常為：含碳量百分之三到百分之四，含硅量百分之一點(diǎn)八到百分之三點(diǎn)二，含錳、磷、硫總量不超過百分之三和適量的稀土、鎂等球化元素。球墨鑄鐵管我們需要了解的小知識(shí)。</p><div

球墨鑄鐵管的公稱口徑為80～2200毫米，與灰口鑄鐵管相比，強(qiáng)度大、韌性好、管壁薄、金屬用量少、能承受較高的壓力，有效長(zhǎng)度有5米，6米及8米；按壁厚不同分P、G兩級(jí)。是鑄鐵管材的發(fā)展方向。球墨鑄鐵管采用煉鐵高爐生產(chǎn)的低磷、低硫的鑄造鐵水，按當(dāng)前國(guó)際上先進(jìn)的離心鑄造、退火工藝，水冷金屬型離心鑄管機(jī)澆鑄而成，經(jīng)過退火、承插口修整、水壓試驗(yàn)、內(nèi)壁襯層水泥、水泥襯層養(yǎng)生、水磨水泥內(nèi)襯、外壁涂敷瀝青漆、瀝青漆烘烤、承口防銹處理、噴嘜頭及包裝等多道工序的精心處理，具有**度、高延伸率、耐腐蝕的鋼筋鐵骨。
