长期来,国内外对缝隙浇口进行了大量研究,但至今较全面、系统地论述缝隙浇口的文献不多。本文在综合有关资料和生产实践的基础上,讨论了缝隙浇口的类型和浇口截面的控制方法,推荐了简易的缝隙浇口最小浇口截面计算图表。一、缝隙浇口的类型和浇口截面的控制方法缝隙浇口的类型分为垂直式、水平式,压式、边式和雨淋式。 For a long time, a great deal of researches have been done on the gap gate at home and abroad, but so far there is not much literature about the gap gate comprehensively and systematically. Based on the comprehensive data and production practice, this paper discusses the types of gate and the method of gate section control, and recommends a simple calculation diagram of minimum gate section of slot gate. First, the type of gap gate and gate section control methods Gap gate type is divided into vertical, horizontal, pressure type, side and rain type.
