正确地配置浇冒口是铸造生产中降低废品率的一个重要前题。浇铸发动机铸件的特点是:壁薄而铁水流程长;大量芯体被铁水包围而铁水又急剧冷却;在铸型中有大量气体产生;铸件厚实部份往往产生粗劣组织。
Proper allocation of risers is an important prerequisite for reducing scrap in foundry production. Casting engine casting is characterized by: thin wall and long flow of molten iron; a large number of cores surrounded by molten iron and rapid cooling of molten iron; in the mold there is a lot of gas generated; castings thick parts tend to produce bad.
