Applications Analysis of the Technology of Mold Electromagnetic Stirring in a Steel Mill

Abstract:

This article mainly analyzes that some steels select mold electromagnetic stirring technique in billet continuous casting production, improve the slab quality effectively in all directions,analyzes how to refine crystal axis with electromagnetic stirring technology, improve the rate of equiaxed crystal, make less bubbles on the slab surface and subsurface, reduce the non-metallic inclusions ,reduce the crack on the surface of the production, reduce the central segregation and make the solidified shell uniform, and etc in detail according to the relevant data. It also put forward some corresponding solutions in accordance with the problems in the production of electromagnetic stirring with billet caster mold in this factory.
