摘要： A method for producing a silicon steel normalizing substrate comprises steelmaking, hot rolling and normalizing steps. A normalizing furnace is used in the normalizing step, and along a moving direction of strip steel, the normalizing furnace sequentially comprises: a preheating section, a nonoxidizing heating section, a furnace throat, furnace sections for subsequent normalizing processing, and a delivery seal chamber. Furnace pressures of the normalizing furnace are distributed as follows: the furnace pressure of a downstream furnace section adjacent to the furnace throat along the moving direction of the strip steel is the highest, the furnace pressure decreases gradually from the furnace section with the highest furnace pressure to a furnace section in an inlet direction of the normalizing furnace, and the furnace pressure decreases gradually from the furnace section with the highest furnace pressure to a furnace section in an outlet direction of the normalizing furnace.

摘要翻译： 一种硅钢标准化衬底的制造方法包括炼钢，热轧和归一化步骤。 在归一化步骤中使用归一化炉，并且沿着带钢的移动方向，归一化炉依次包括：预热部，非氧化加热部，炉喉，随后的标准化处理的炉部，以及输送密封室 。 归一化炉的炉压分布如下：沿钢带移动方向与炉喉相邻的下游炉段的炉膛压力最高，炉膛压力从炉膛最高炉膛压力逐渐降低 到归一化炉的入口方向的炉段，并且炉压力从具有最高炉压的炉段逐渐降低到归一化炉的出口方向的炉段。
