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 nodules, thereby significantly improving the properties of cast ir…

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 graphitization process is hindered, and cementite and white…

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., 75SiFe 8 minutes) after incubation can lead to coarse and un…

In the production of gray iron castings, excessively high pouring temperatures can significantly increase the risk of rejects. When the temperature reaches or exceeds 1420°C, the sand mold, especially the area with complex sand core, will ex…
