방향성 전기강판의 고온소둔시 침탄억제 방법Method of Carburizing Inhibition at High Temperature Annealing of Thick Electrical Steel Sheet

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도는 소둔분리제로 사용한 MgO 중의 탄소함량과 소온소둔후 소재의 탄소함량 변화와의 관계를 나타낸그래프.1 is a graph showing the relationship between the carbon content of MgO used as an annealing separator and the carbon content change of the material after an annealing.

제 2 도는 공기중에서 정치시간 변화와 MgO의 탄소함량 변화와의 관계를 나타낸 그래프.2 is a graph showing the relationship between the change in settling time and the change in carbon content of MgO in air.

Claims (1)

통상의 방향성 전기강판 제조공정에 있어서 탈탄소둔판에 소둔분리제로 MgO를 도포할때 탄소성분을 400ppm이하로 함유한 MgO를 도포하고, 고온소둔전에 100∼180℃의 건조분위기에서 유지하는 것을 특징으로 하는 방향성 전기강판의 고온소둔시 침탄을 억제하는 방법.In the general oriented electrical steel sheet manufacturing process, when MgO is applied to the decarbonized annealing plate as an annealing separator, MgO containing 400 ppm or less of carbon component is applied and maintained in a dry atmosphere at 100 to 180 ° C. before high temperature annealing. Method of suppressing carburization during high temperature annealing of the grain-oriented electrical steel sheet. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
