    • PURPOSE:To produce a titled electrical steel strip at a low cost by applying a magnetic field in a specific temp. range to a strip made by a direct sheet making method in its longitudinal direction during cooling in a final annealing process for the strip. CONSTITUTION:Molten steel is ejected onto a cooling surface of a cooling body moving at high speeds, and is quickly cooled and solidified, whereby a strip of 20- 500mu thickness is made. Next, if necessary, it is annealed or annealed after rolling. A magnetic field is applied within the following temp. range in the longitudinal direction of the strip during cooling in the final annealing process applied at above the curie temp. Tc deg.C determined by the component composition of the strip. Namely, with the surface temp. of the strip as a reference, a magnetic field application start temp. Ts deg.C and a magnetic field application end temp. Tf deg.C are so set as to satisfy the expressionsI, II, III. In this way, the electrical steel strip formed of easy magnetization anisotropy in the longitudinal direction of 20-300mu thickness is produced.
    • 目的:通过在特定温度下施加磁场,以低成本生产标称的电工钢带。 范围是在用于带材的最终退火工艺中的冷却期间通过直接制片方法在其纵向上制造的条带。 构成:将钢水喷射到高速运转的冷却体的冷却面上,迅速冷却固化,制成厚度20〜500μm的条。 接下来,如果需要,在轧制后进行退火或退火。 在以下温度下施加磁场。 在最终退火工艺中的冷却过程中,在高于居里温度下施加的条带的纵向范围。 Tc℃由条的组分组成确定。 即表面温度。 的条带作为参考,磁场施加开始温度。 Ts°C和磁场施加结束温度。 Tf deg.C被设定为满足表达式I,II,III。 以这种方式,产生了长度方向上容易磁化各向异性的电钢带,厚度为20-300μm。
