FRAMSTELLNING AV BAND AV ENSARTAT ORIENTERAT KISELSTAL

摘要

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 DEG and 1250 DEG C; slowly cooling the silicon steel strip to a temperature below 500 DEG C to precipitate dissolved sulfur as manganese sulfide; and hot-rolling the continuously cast silicon steel strip at a temperature over 1300 DEG C.
