热侧冒口是浇口通过冒口充填,补缩铸件的一种浇冒口型式。它的补缩能力强,排渣去气效果好,通用性大,适应性广,是中小铸铁件广泛采用的一种浇冒口系统。本文从铸铁件均衡凝固的原则出发,试验研究冒口和冒口颈的搭配关系、冒口颈的尺寸和冒口颈的位置对补缩的影响。以提高冒口的补 Hot side riser is the gate through the feeder filling, shrink casting a kind of pouring riser type. Its ability to replenish strong, slagging to the gas effect, versatility, wide adaptability, is a widely used cast iron casting a mouth system. Based on the principle of balanced solidification of cast iron, the paper studies the relationship between riser and riser neck, the size of riser neck and the location of riser neck on the constriction. To improve riser fill
