전체 글 (20) 썸네일형 리스트형 Influence of the Submerged Entry Nozzle’s Bottom Well on the Characteristics of Its Exit Jets 1. IntroductionIn modern continuous steel casting, the submerged entry nozzle (SEN) plays a crucial role in delivering molten steel from the tundish into the mold in a controlled, stable manner. The flow behavior of the liquid steel as it exits the SEN significantly impacts the hydrodynamics within the mold, which in turn influences solidification patterns, meniscus stability, inclusion distribu.. Tundish Stopper Rod: Definition, Design, Function, and Performance in Continuous Casting 1. IntroductionIn modern steelmaking, continuous casting has become the dominant technology for transforming molten steel into semi-finished products such as slabs, blooms, and billets. Within this process, the tundish plays a critical role as an intermediate vessel between the ladle and the mold. Beyond its function as a distributor of liquid steel, the tundish is also a metallurgical reactor w.. 연속주조 공정에서 침지노즐(SEN) 오프셋이 유동장에 미치는 영향 1. 서론연속주조(Continuous Casting) 공정은 현대 철강 생산에서 가장 핵심적인 제조 기술 중 하나로, 주조 품질과 생산성은 주형(Mold) 내부의 용강 유동 특성에 의해 크게 좌우된다. 이 유동 특성을 지배하는 가장 중요한 요소 중 하나가 바로 **침지노즐(Submerged Entry Nozzle, SEN)**이다. SEN은 턴디시에서 공급된 용강을 주형 내부로 안정적으로 유입시키는 역할을 수행하며, 그 기하학적 형상, 분사각, 침지 깊이, 그리고 오프셋(offset) 여부는 주형 내 유동장(flow field)에 중대한 영향을 미친다.SEN 오프셋이란, 노즐이 주형 중심선과 정확히 일치하지 않고 한쪽 방향으로 편심되어 설치된 상태를 의미한다. 실제 산업 현장에서는 장비 공차, 설치 오차.. Composition of Tundish Metering Nozzle: Materials, Structure, and Performance in Continuous Casting IntroductionIn modern continuous steel casting, the tundish plays a critical metallurgical role as a buffer, distributor, and refining vessel between the ladle and the mold. Among all tundish functional refractories, the tundish metering nozzle is one of the most important flow control components. Its material composition, internal design, and microstructure directly influence steel cleanliness,.. How to Fix a Sub-Entry Shroud in Continuous Casting Operations 1. IntroductionThe sub-entry shroud (SES) is a critical refractory component in the continuous casting process, positioned between the ladle nozzle and the tundish or directly above the mold entry, depending on caster design. Its primary function is to protect molten steel from atmospheric re-oxidation, stabilize steel flow, and prevent slag entrainment during steel transfer. Proper installation.. European Sub-Entry Shroud Market: Trends, Drivers, and Future Outlook IntroductionThe sub-entry shroud (SES) is a specialized refractory component used in the continuous casting of steel, acting as a protective tube between the ladle nozzle and the tundish entry to shield molten steel from atmospheric oxidation, stabilize flow, and improve steel quality. Sub-entry shrouds play a critical role in modern steelmaking by helping to prevent re-oxidation, reduce inclusi.. Key Refractory Products Used in the Tundish System of Continuous Casting 1. IntroductionIn modern continuous casting steelmaking, the tundish is not merely an intermediate vessel between the ladle and the mold; it is a metallurgical reactor that plays a crucial role in steel cleanliness, temperature control, and flow optimization. To achieve these objectives, a series of functional refractory products are installed in and around the tundish. These refractory items mu.. How to Avoid Problems of the Sub-Entry Nozzle (SEN) in Continuous Casting 1. IntroductionThe Sub-Entry Nozzle (SEN) is a critical functional refractory component in the continuous casting process of steel. Positioned between the tundish and the mold, the SEN controls the flow of molten steel into the mold cavity while protecting the steel stream from secondary oxidation and regulating flow patterns to ensure stable solidification. Despite its relatively small size com.. 이전 1 2 3 다음
