本发明涉及一种含磷无铝高效无取向硅钢生产方法，生产方法取消常化工艺，具体步骤如下：1)将钢水冶炼至目标成分后，浇铸成坯；2)板坯热装，热装温度≥500℃，热轧板坯加热炉均热段板坯温度1150～1200℃；终轧温度控制在860～930℃，卷取温度700～800℃3)酸洗后冷轧，控制冷轧整体压下率80％以内，至成品厚度；4)连续退火炉快速加热段温度设定1050～1180℃，增加有利织构组织形核，均热段温度设定830～950℃，全氮气干气氛保护，退火工艺速度120～150m/min，满足晶粒度8～4级。本发明不需进行热轧卷常化处理，降低了制造成本。

本发明涉及取向硅钢技术领域，尤其涉及一种取向硅钢边浪的控制方法、装置、设备和存储介质，该方法包括：在将通过脱碳退火阶段的取向硅钢的带钢进行卷取过程中，在带钢的下端侧上刻上刻痕线，其中，下端侧为带钢与高温退火炉的承托底板接触的一侧，刻痕线平行于带钢轧制的方向；控制卷取后的带钢通过高温退火阶段和热拉伸平整阶段后至精整阶段时，沿着刻痕线，切除带刚的边浪；其中，边浪为在带钢的刻痕线至下端侧的边的部分。该控制方法可显著改善高温退火后取向硅钢边部浪形，有效降低精整切边量，提高取向硅钢的板形质量及成材率，降低生产成本。

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...
