METHOD FOR PRODUCING SILICON STEEL NORMALIZING SUBSTRATE.
摘要
<p>A method for producing a silicon steel normalizing substrate comprises: steelmaking, hot rolling and normalizing steps. The normalizing step uses a normalizing furnace having a nonoxidizing heating furnace section. The nonoxidizing heating furnace section comprises more than 3 furnace zones. An energy investment ratio of the furnace zones used in the nonoxidizing heating furnace section is adjusted, so as to control an excess coefficient α of the nonoxidizing heating furnace section to be within a range of 0.8≤α<1.0.</p>
