【摘要】 冒口高度对钢锭凝固过程中的疏松、缩孔等缺陷有一定影响。本文建立了60t扁钢锭凝固过程的数学模型,研究冒口高度对钢锭的组织结构和内部缺陷的影响,确定钢锭缩孔缺陷和凝固速度随冒口高度的变化规律.综合考虑实际生产等因素,建议60t扁钢锭的冒口高度为540mm。更多还原

【Abstract】 Riser height has a certain influence on the porosity,shrinkage and other defects in the solidification process of steel ingots.A mathematical model for solidification process of 60 t ingot is established in this paper.The influence of riser height on the structure and internal defects of ingot is studied,and the variation rule of ingot shrinkage defect and solidification speed with riser height is determined.Considering factors such as actual production,it is recommended that the riser height of the 60 t flat steel ingot be 540 mm.更多还原
