Abstract

The 220mmx260mm section continuous casting billet in the company of electric furnace was the research object in this paper. At the same time, according to the theory of solidification shell thickness calculation formula combining design measure specific location of the solidification shell thickness test. It can provide reliable basis for the subsequent F-EMS optimization and basic data support for the transformation and improvement of solidification structure of billet under soft reduction. Accurately determine the casting billet specific location of the solidified shell thickness and solidification coefficient for optimal setting at the end of the end of the electromagnetic stirring (F-EMS) and light pressure parameters, maximum play F-EMS and gently press down at the end of the effect of center segregation and osteoporosis has important reference meaning, at the same time, according to the thickness of the solidified shell can be used to analyze cause of forming defect, the rationality of the secondary cooling water distribution system, and forecast the potential of improving continuous casting speed, etc [1-4].
