1. Combined Application of Multidisciplinary Defect Detection TechniquesFluorescent Penetrant Testing (PT) for Surface Defects: For non-ferrous metal components such as stainless st…

Control Points:Adopt an "open gating system" (total area of inner runners > 1.5 times that of the sprue) to match the filling speed with the casting structure: 1.0–1.2 m/…

Nodulizers are critical additives in cast iron production, whose core function is to induce the transformation of graphite in molten iron from a flaky morphology to spherical nodule…

Silicon, on the other hand, promotes the graphitization process, which together affects the growth and distribution of graphite.If the carbon equivalent (CE=C 0.3Si) is too low, the…

Inculation treatment is a key part of gray cast iron production, with the aim of promoting graphitization and refining the graphite structure.Insufficient inoculant addition (e.g., …
