style="text-indent:25px">鋼箱梁和松孔的特征及產(chǎn)生原因：它是金屬枝晶間或晶界孔洞，分布在鑄件補(bǔ)縮不到的部位，用肉眼無法分辨，但在顯微鏡下可看到成片的小孔，在斷口上呈淡黃、灰色或黑色，一般在鑄件內(nèi)部，有時(shí)穿透整個(gè)壁厚，造成鑄件氣密性不合格。松孔是金屬不致密的宏觀疏松，可用肉眼分辨，分布在鋼箱梁，露出表面后則呈蟲蛀狀所以又稱為蟲蛀狀疏松”。產(chǎn)生的原因有：凝固過程中補(bǔ)縮不良，澆鑄系統(tǒng)和冒口設(shè)置不當(dāng)，冷鐵位置和厚度不當(dāng)，鑄件形成毛刺、飛邊等，引入合金液的位置不當(dāng)；鑄件局部過熱和金屬型溫度過高，澆鑄溫度過髙；合金中氣體含量多，促使顯微疏松形成和加??；爐料及熔劑潮濕，回爐料等表面腐蝕，鑄型通氣不I某些合金本身的結(jié)晶間隔大，顯微疏松傾向性大，變質(zhì)或加鋯細(xì)化合金不夠金的結(jié)晶組織粗大，加劇和促使顯微疏松的形成。一階段受力疊合梁工階段在預(yù)制梁下設(shè)有可靠支撐,能保證施工階段作用的荷載全部傳給支撐。杭州疊合梁設(shè)計(jì)</p><p
