金属质量的控制是铸造工作者使铸件性能满足用户技术要求的方法。本文作者探讨了用热分析技术测定碳和硅的含量;数字式仪器的应用;三角试块试验仍然具有重要性;以及用超声波试验测定铸件实物的球化率。铸造车间对金属质量的测试,其目的在于能够预示并控制铸件内部的性能,并具有确保
The control of the quality of the metal is a method by which the casting worker makes the casting’s properties meet the technical requirements of the user. The authors explored the determination of carbon and silicon content using thermal analysis techniques; the application of digital instrumentation; the testing of the triangular test blocks is still of importance; and the rate of spheroidization of the castings is measured using ultrasonic testing. Casting workshop on the quality of the test, the purpose is to be able to predict and control the performance of the interior of the casting, and has ensured
