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。
The metal rheology of steel 20 CrMnTiH during rolling process of 430 mm ×300 mm casting bloom to Φ130mm 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.
