【摘要】 浇注过程的卷气再氧化已引起人们的关注。本文注重浇注工艺因素对注流卷气量的影响,通过因素分析和水力学模型实验,得到了如下关系式Qg=4.17×10^-2W^0.771d^0.202H^0.601对各因素影响钢液再氧化的机理进行了详尽的分析讨论。所得结果对寻求再氧化的防护措施很有启发作用。更多还原

【Abstract】 The reoxidation of steel caused by air entrainment has aroused great in- terests.This paper deals mainly with the effects of some technical factors on the rate of air entrainment during the up-hill teeming process.The fol- lowing gas entrainment equation is obtained based on units-analysis and the water model study Qg=4.17 * 10^-2W^0.771d^0.202H^0.601 and how each factor affects the reoxidation of steel has also been discussed in detail.The results obtained would be useful to measure taken for prote- ctive casting.更多还原
