摘要
废气蜗壳是12V 230柴油机中的重要铸件之一,几何尺寸和冶金质量要求都比较严格。一、铸件结构和技术要求铸件外形尺寸Φ560×340,毛重61kg,主要壁厚10mm。铸件结构复杂,两条蜗牛气腔在空间盘旋交错,腔内通过高温废气,其外包有不规则的水腔。轴承座支承着高速运转的转子。铸件材质ZL104铝合金。
The exhaust volute shell of 12V230 diesel engine is a complicated aluminium alloy casting with water chamber. This paper introduces its casting technique. It has bcen proved that foundry processing is successed to keep the demensional accuracy and the good internal quality. It is conducive to production of the same type castings.
