Abstract
A process for inhibiting grain growth in the production of a single oriented continuously cast silicon steel strip with high magnetic characteristics, including the steps of continuously casting a silicon steel strip; solubilizing iron sulfide in the silicon steel strip by uniformly heating the strip to a temperature between 1050.degree. and 1250.degree. C; slowly cooling the silicon steel strip to a temperature below 500.degree. C to precipitate dissolved sulfur as manganese sulfide; and hot-rolling the continuously cast silicon steel strip at a temperature over 1300.degree. C.
