Abstract

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.
