本发明公开了一种低铁损高磁导率无取向电工钢及其生产方法，所述生产方法包括以下步骤：钢水连续浇铸成板坯，板坯经加热炉加热，再经热轧得到热轧板，然后经空冷和水冷后在500～650℃进行卷取；热轧板经常化处理、盐酸酸洗；酸洗后在可逆轧机上进行冷轧；最后经成品退火，退火温度为840～900℃，加热时间为240～500s；然后以不超过3℃/s的冷却速度冷却至500℃以下；涂覆绝缘涂层、固化，后经二次退火，即可得到低铁损高磁导率无取向电工钢，其磁性能满足P1.5/50≤3.50W/kg，μ1.5≥3800Gs/Oe，B5000≥1.76T的要求。

本发明涉及一种取向硅钢热轧钢带的板形控制方法，所述取向硅钢热轧钢带的工艺流程包括铸坯加热过程、轧制过程及层流冷却过程；其中轧制过程中采取取向硅钢与普钢交叉轧制的方式；粗轧过程采取R1轧制1道次、R2轧制5道次的1+5轧制工艺，并控制轧制工艺参数；精轧过程中控制F1～F7轧制工艺参数。本发明通过设定合理的交叉轧制工艺及取向硅钢热轧工艺，使取向硅钢的轧制稳定性大幅提高，取向硅钢带形控制良好，凸度控制在30～50μm之内，楔形控制在30μm之内，板形平坦度控制在25iu之内；从而为冷轧工序提供了优质原料。
