将Fe-1.5Si硅钢试样分别在1 000~1 200℃空气条件下氧化30 min,观察发现在1 000℃和1 100℃时,氧化层与基体界面处存在硅酸亚铁,而当温度为1 200℃时,硅酸亚铁不但存在于界面处,同时也存在于氧化层中.将各温度下得到的带有氧化层的试样进行单道次热轧试验,压下率分别为10%和30%,发现1 000℃和1 100℃时,较高的压下率使氧化层破碎更加严重,但是单道次热轧未能改变氧化层的结构;当温度为1 200℃时,由于液态的硅酸亚铁的出现,单道次热轧能够将界面处的液化的硅酸亚铁层挤压到氧化层中,消除了硅酸亚铁层的钉扎基体的效应,改善了氧化层与基体界面的平直度. Specimens of Fe-1.5Si silicon steel were oxidized at 1 000 ~ 1 200 ℃ in air for 30 min.At 1 000 ℃ and 1 100 ℃ fayalite was observed at the scale/substrate interface.While at 1 200 ℃fayalite was found both at the scale/substrate interface and at the outer oxide layer.Then after the single-pass hot rolling process,with the compression ratio of 10% and 30%,it was found that at 1000 ℃ and 1 100 ℃,higher compression rate accelerated the broken of the scale layers,but the scale structure was not affec...
