antipiping compound

The common foundry methods for nodular iron castings with medium/ small size and their design were introduced including:process characteristics o f nodular iron;types of gating systems ,their choice and design;sorts of feed ers,their principles and choice;feeder design with modulus method.

介绍日本中、小球墨铸铁件的常用工艺以及设计方法,包括:球墨铸铁的工艺特点;浇注系统的形式和选择;浇注系统的设计方法;冒口的种类和原理,选用方法,以及用模数法设计冒口的方法。

By properly determining the dimensions of the feeder and its neck according to the principle of pressure-controllable feeder to control the inner pressure of casting,the shrinkageless casting was obtained,and the process yield of the casting was increased.

根据可控压力冒口原理,选择适当的冒口和冒口颈尺寸,控制铸件内部压力,获得无缩松缺陷的铸件,并提高了铸件的工艺出品率。

This article discusses balance compencation in casting,and researches feeding mechanism and process,finds that the point of the method is usage of extra pressure on feeder metal which comes from special pressure machine.

介绍了平衡补缩铸造方法 ,并对其补缩机理和补缩过程进行了研究 ,指出平衡补缩铸造方法的关键在于采用专用压力机对冒口金属施加足够大的外加压力。
