Methods to solve the quality problems of ductile iron castings

- Mar 24, 2021-

1. Production technology factors: Without considering the defects of ductile iron castings, the main factors affecting the performance of ductile iron castings are the composition of molten iron and the matrix structure. In terms of the composition of molten iron, it is necessary to consider the changes of various elements and the chemical composition required by the casting, so as to select the charge reasonably. At the same time, attention should be paid to the operation process during the smelting process to ensure the temperature and composition stability of the molten iron to avoid quality problems in the partial casting of the product.   


2. Quality management factors: In terms of production quality management, the training of production technicians should be strengthened, casting technology should be improved, quality control should be strengthened, and control of each quality link of production should be strengthened, problems can be found in time, problems can be solved, and each process should be done well. The corresponding quality record report.
