鑄造廠家講述影響球墨鑄鐵件質量的因素：　　
 　　1:是鑄件的設計工藝性.進行設計時,除了要根據工作條件和金屬材料性能來確定鑄件幾何外形.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計的合理性,即明顯的尺寸效應和凝固.收縮.應力等問題　　

        2:要(yao)有(you)合(he)(he)理(li)的(de)鑄(zhu)(zhu)(zhu)造(zao)工(gong)藝.即根據鑄(zhu)(zhu)(zhu)件(jian)(jian)結(jie)構.重量和(he)(he)尺(chi)寸(cun)大小,鑄(zhu)(zhu)(zhu)造(zao)合(he)(he)金特性和(he)(he)生產(chan)條(tiao)(tiao)件(jian)(jian),選擇(ze)合(he)(he)適(shi)的(de)分型面和(he)(he)造(zao)型.造(zao)芯方法,合(he)(he)理(li)設置鑄(zhu)(zhu)(zhu)造(zao)筋.冷鐵.冒口和(he)(he)澆(jiao)注系統等(deng).以保證獲得優質鑄(zhu)(zhu)(zhu)件(jian)(jian).鑄(zhu)(zhu)(zhu)造(zao)生產(chan)中,要(yao)對(dui)鑄(zhu)(zhu)(zhu)件(jian)(jian)的(de)質量進(jin)行控(kong)制與檢(jian)(jian)驗(yan)(yan)(yan)(yan).首先(xian)要(yao)制定(ding)(ding)從原材(cai)料.輔(fu)助材(cai)料到每(mei)(mei)種具體(ti)產(chan)品(pin)的(de)控(kong)制和(he)(he)檢(jian)(jian)驗(yan)(yan)(yan)(yan)的(de)工(gong)藝守則與技術條(tiao)(tiao)件(jian)(jian).對(dui)每(mei)(mei)道工(gong)序都嚴(yan)格按工(gong)藝守則和(he)(he)技術條(tiao)(tiao)件(jian)(jian)進(jin)行控(kong)制和(he)(he)檢(jian)(jian)驗(yan)(yan)(yan)(yan).最(zui)后(hou)對(dui)成品(pin)鑄(zhu)(zhu)(zhu)件(jian)(jian)作質量檢(jian)(jian)驗(yan)(yan)(yan)(yan).要(yao)配(pei)備合(he)(he)理(li)的(de)檢(jian)(jian)測方法和(he)(he)合(he)(he)適(shi)的(de)檢(jian)(jian)測人員.一般對(dui)鑄(zhu)(zhu)(zhu)件(jian)(jian)的(de)外(wai)觀質量,可(ke)用比較樣(yang)塊(kuai)來判定(ding)(ding)鑄(zhu)(zhu)(zhu)件(jian)(jian)表面粗糙度 

 　　3:是(shi)球墨鑄(zhu)鐵件(jian)用原材(cai)料的質(zhi)量(liang).金屬爐(lu)料.耐火材(cai)料.燃料.熔劑(ji).變質(zhi)劑(ji)以及鑄(zhu)造砂(sha).型砂(sha)粘(zhan)結劑(ji).涂料等(deng)材(cai)料的質(zhi)量(liang)不(bu)合標準,會(hui)使鑄(zhu)件(jian)產生氣孔.針孔.夾(jia)渣.粘(zhan)砂(sha)等(deng)缺陷,影響鑄(zhu)件(jian)外(wai)觀質(zhi)量(liang)和內部質(zhi)量(liang),嚴重時會(hui)使鑄(zhu)件(jian)報廢.第四是(shi)工(gong)(gong)藝(yi)操(cao)作(zuo),要制定合理的工(gong)(gong)藝(yi)操(cao)作(zuo)規(gui)程(cheng),提高工(gong)(gong)人的技術水平,使工(gong)(gong)藝(yi)規(gui)程(cheng)得到(dao)正確實施.
