ABSTRACT The 10 kg induction furnace experiments were carried out to investigate the oxidation and decarburization behaviour and melting characteristics of the steel bars with different carbon contents. In addition, the melting rate of steel bars in the molten bath with different carbon contents and stirring intensity was also studied. Under the same heating conditions, high carbon GCr15 bearing steel is more easily oxidized than 20# steel due to its higher carbon content, while the decarbonization is the opposite. The melting rate of GCr15 bearing steel is greater than that of 20# steel because of its higher carbon content and lower melting point. And the melting rate of steel bar under oxidation condition is slightly higher than that of the non-oxidized steel bar. It was also found that an increase in the carbon content and stirring intensity of the molten metal is beneficial to accelerate the melting of steel bar.

钢液中不同含碳量废钢的熔化特性

摘要 通过 10 kg 感应炉实验，研究了不同碳含量钢筋的氧化脱碳行为和熔化特性。此外，还研究了不同碳含量和搅拌强度的钢棒在熔池中的熔化速度。在相同的加热条件下，高碳GCr15轴承钢由于含碳量较高，比20#钢更容易氧化，而脱碳则相反。GCr15轴承钢的熔化速度比20#钢大，因为其含碳量较高，熔点较低。并且氧化状态下钢筋的熔化速度略高于未氧化的钢筋。
