钛稳定不锈钢连铸坯中的夹杂物

Non-Metal Inclusion in the Continuous Casting Strand for Ti-Stabilized Stainless Steel

    摘要
  • 摘要: 本文调查了弧形连铸机浇注钛稳定不锈钢铸坯中非金属夹杂物数量、形态、组成和分布。结果指出:Ti 稳定不锈钢中夹杂物分为两类:一类是含有 Ti、Na和 K的氧化物系,其尺寸为100~200μm;另一类是 TiN 群簇团,单相 TiN<30μm。并发现在内弧表面和铸坯中心处有集聚现象。

     

    Abstract: The quantity, morphology,composition and dimensional distribution of inclusions for the continuous casting strand of Ti-stabilized stainless steel has been investigated in this paper. The results arc as follows, there arc two kinds of inclusions in this stainless steel. One is the oxide containing Ti、Na, K. The size of oxide are 100-200 μm. The other is TiN cluster. The single phase of TiN is less than 30 μm. And the accumulation of inclusions could be seen both in the surface of inside radius and the centre of slab.
