在(zai)铸态(tai)时(shi)断口(kou)为(wei)灰(hui)色(se)，浅黄(huang)色(se)经热(re)(re)处理后为(wei)灰(hui)白浅黄(huang)或灰(hui)黑色(se)在(zai)x光(guang)底片(pian)上呈(cheng)云雾状严(yan)峻的(de)(de)呈(cheng)丝状缩(suo)松可通过X光(guang)、荧光(guang)低(di)倍断口(kou)等检查方法(fa)发现发生原因：1.冒口(kou)补缩(suo)效果差2.炉料含气量太多3.内浇道邻近(jin)过热(re)(re)4.砂型水分过多，砂芯未烘(hong)干5.合金晶(jing)粒粗大6.铸件在(zai)铸型中的(de)(de)方位不(bu)当7.浇注温度过高，浇注速(su)度太快  

铝铸件防止方法：1.从(cong)冒口补浇金(jin)属液，改进冒口规(gui)划2.炉料应清(qing)洁(jie)无(wu)腐(fu)蚀3.铸件缩松处设置冒口，安放(fang)冷铁(tie)或冷铁(tie)与(yu)冒口联用4.控制型砂水分，和(he)砂芯枯燥5.采纳细化(hua)品粒(li)的(de)(de)措施6.改进铸件在(zai)铸型中的(de)(de)方位下降浇注温度(du)和(he)浇注速度(du)
