在我国中、小型铸造车间,压边浇口由于其操作简便,易于掌握,广大铸造工人乐于接受,目前已广泛地应用在铸造生产中。现在,除了普通铸铁件外,在球铁件及铜、铝、镁等合金铸造中也已得到推广,并且在最近几年发展较快。这主要是因为,压边浇口是一种充型平稳、补缩能力强、撇渣除气效果好,既能获得合格铸件,又较为简便的浇注系统。
In our country, the small casting workshop, the pressure side gate because of its easy operation, easy to grasp, the majority of foundry workers are willing to accept, has been widely used in casting production. Now, in addition to ordinary cast iron parts, it has also been promoted in ductile iron castings as well as alloy castings such as copper, aluminum and magnesium, and has rapidly developed in recent years. This is mainly because the pressure side gate is a filling filling stable, strong ability to fill, skimming slag degassing effect, both to obtain qualified castings, and more simple pouring system.
