원형 빌렛 연속주조에 있어서 유동 - 열전달 - 응고층 변형 거동의 연결해석

摘要: A numerical model has been developed to analyze the heat transfer, fluid flow and deformation behavior of solidifying shell in continuously cast round billet. The temperature distribution billet mold pattern molten steel were determined using finite difference method. thermo-elasto-plastic stress fields formation air gap along wall analyzed element transfer coefficient between was calculated by coupling above two procedures. This shows good agreements with reported experimental results. effects on have simulated variation casting carbon contents. variables thickness also predicted.
