论述了原材料控制对于湿型砂铸件生产的重要性,阐述了碳质添加剂对铸件质量的影响,为了保证型砂质量的稳定,必须深入了解和控制型砂粒度、总碳量、挥发分和灼烧减量的关系。考察了各种预测和控制方法。强调了各种添加剂的性能及其作用以及它们的相互影响。对来料控制检测方法和加入混砂机的添加剂进行了讨论。对检测结果、控制操作和用湿型砂获得性能稳定,质量高的铸件需要采取的措施做了评述,强调要了解和控制碳质添加剂对铸件性能的影响。
The importance of raw material control for the production of wet sand castings is discussed. The influence of carbonaceous additives on castings quality is expounded. In order to ensure the stable quality of sand, it is necessary to understand and control the sand size, total carbon content, volatile matter and ignition loss Relationship. Examined a variety of prediction and control methods. Emphasize the performance of various additives and their effects and their interactions. The control methods of incoming control and the additives added into sand mixer are discussed. Commenting on the test results, control operations and the steps required to obtain stable and high quality castings from wet sands emphasizes the need to understand and control the effect of carbonaceous additives on casting performance.
