PROCESS FOR PRODUCING A GRAIN-ORIENTED SILICON STEEL SHEET FROM SILICON STEEL SLAB

摘要

Process for producing a grain-oriented silicon steel sheet from silicon steel slabs, particularly from continuously cast steel slabs, comprising at least one recrystallization rolling at high reduction rate in a temperature range from 1190 DEG C. to 960 DEG C. in the hot rolling step. The process of the present invention is very effective in preventing the streaks of smaller, poorly oriented grains very often seen in the final product produced from silicon steel slabs.
