低碳微合金非调质钢的非金属夹杂物研究

STUDY ON NON-METALLIC INCLUSIONS OF NON-QUENCHED AND TEMPERED LOW CARBON MICROALLOY STEEL

通过热力学计算和实验,分析低碳Nb-V-Ti-N系微合金非调质钢中的非金属夹杂物形成的可能性以及如何通过控制钢中元素的含量,来影响夹杂物的类型,从而为进一步提高钢的纯净度提供理论依据。

Thermodynamic calculation and experiment were performed in the Nb-V-Ti-N low carbon microalloy non quenched and tempered steel to analyze the forming possibility of non-metallic inclusions, and to study the influence of main elements content on the types of non-metallic inclusions, therefore, to provide evidence for improving steel cleanliness.
