摘要: 通过20CrMnTiH钢430 mm×300 mm连铸坯射钉试验模拟铸坯粗轧和至Φ130 mm钢材轧制过程中的金属流变。试验结果表明,平行于射钉方向,钉子变形延展成扁平状,垂直于射钉方向,钉子压缩成镰刀状弯曲,轧制对改善成品钢材横截面上的宏观碳偏析无明显效果。

Abstract: The metal rheology of steel 20CrMnTiH during rolling process of 430 mm x 300 mm casting bloom to Φ130 mm steel product is simulated by bloom pin-shooting test. Test results show that in the direction of parallel to pin-shooting, the pin is deformed and extend-spread to flat type, and in the direction of perpendicular to pin-shooting, the pin is compressed to sickle-type bend, therefore the effect of rolling process on macro-carbon segregation in cross section of finishing products is not obvious.
