三、简单的板铸件竖式板铸件浇注中所用的一些基本原理当然也适用于竖式圆柱铸件以及箱体铸件等的浇注。因此,本节的内容可应用于多种实际铸件的生产。 1.水平板铸件将板模水平放置进行浇注,历来受到多种理由的反对。在这种铸造方法中,液体金属流是以不规则的、无法控制的小流束遍布模腔。对容易形成表面膜的合金,表面膜就在这些流束的两侧面上形成。由于表面膜沿
Third, the simple plate casting Vertical plate casting casting some of the basic principles used in the course also applies to the vertical cylindrical castings and casting boxes and other casting. Therefore, the contents of this section can be applied to a variety of actual casting production. 1. Horizontal plate casting Placing molds horizontally for casting has always been opposed by many reasons. In this casting method, the liquid metal flow is distributed throughout the mold cavity with an irregular, uncontrolled flow of small streams. For the easy to form the surface film alloy, the surface film is formed on both sides of these streams. Due to the surface film along
