style="font-size:14px;">鑄鐵井蓋的設(shè)計(jì)工藝性。進(jìn)行設(shè)計(jì)時(shí),除了要根據(jù)工作條件和金屬材料性能來確定鑄鐵井蓋幾何形狀,尺寸大小外,還必須從鑄造合金和鑄造工藝特性的角度來考慮設(shè)計(jì)的合理性,即明顯的尺寸效應(yīng)和凝固,收縮,應(yīng)力等問題,以避免或減少鑄鐵井蓋的成分偏析,變形,開裂等缺點(diǎn)的產(chǎn)生。</span> </p> <p> <span style="font-size:14px;">第二要有合理的鑄造工藝。即根據(jù)鑄鐵井蓋結(jié)構(gòu),重量和尺寸大小,鑄造合金特性和生產(chǎn)條件,選擇合適的分型面和造型,造芯方法,合理設(shè)置鑄造筋,冷鐵,冒口和澆注系統(tǒng)等.以保證獲得出色鑄鐵井蓋。</span> </p> <p> <span style="font-size:14px;">第三是鑄造用原材料的質(zhì)量。球墨鑄鐵井蓋作為軸類件,如柴油機(jī)的曲軸,連桿要求強(qiáng)度高同時(shí)韌性較好的綜合機(jī)械械性能,對鑄鐵井蓋進(jìn)行調(diào)質(zhì)處理。井蓋分為球墨鑄鐵井蓋，云南井蓋專業(yè)定做、球墨井蓋、鑄鐵井蓋、高分子復(fù)合井蓋、防沉降井蓋、水泥井蓋，云南井蓋專業(yè)定做、隱形井蓋、藝術(shù)井蓋、不銹鋼井蓋、五防井蓋、輕型井蓋，云南井蓋專業(yè)定做、重型井蓋。所有的產(chǎn)品，規(guī)格型號可根據(jù)客戶要求定做（昆明多果商貿(mào)有限公司）。</span>

<p> <span style="font-size:14px;">由于球墨鑄鐵的球狀石墨微觀結(jié)構(gòu)，在減弱振動能力方面，球墨鑄鐵優(yōu)于鑄鋼，因此更加有利于降低應(yīng)力。選擇球墨鑄鐵的一個(gè)重要的原因在于球墨鑄鐵比鑄鋼成本低。球墨鑄鐵的低成本使得這種材料更加受歡迎，鑄造效率更高，也較少了球墨鑄鐵的機(jī)加工成本。</span> </p> <p> <span style="font-size:14px;">球墨鑄鐵的強(qiáng)度和鑄鋼的強(qiáng)度是可比的。球墨鑄鐵具有更高的屈服強(qiáng)度，其屈服強(qiáng)度蕞低為40k，而鑄鋼的屈服強(qiáng)度只有36k。在大部分市政應(yīng)用領(lǐng)域，如：水、鹽水、蒸汽等，球墨鑄鐵的耐腐蝕性和抗氧化性都超過鑄鋼。</span>
