用水力学模型试验研究了工字形双层底盘的分流状况、锭模内流体流动特征和下注系统各部尺寸的内在联系。实验表明:中注管、汤道及下水口的断面积对锭模内流体均匀有力的上升有直接关联;按照单位时间注钢量及流体流动特征选取恰当的中注管流体通过系数,有利于防止浇注过程中注管的“呕钢”现象。
Hydraulic model tests were carried out to study the shunting conditions of the I-shaped double-deck chassis, the fluid flow characteristics of the ingot mold and the inner dimensions of each part of the betting system. The experimental results show that the cross-sectional area of the middle injection tube, the soup tube and the sewer nozzle is directly related to the uniform and powerful fluid rise in the ingot mold. Selecting the proper fluid injection through the tube according to the amount of injected steel per unit time and the fluid flow characteristics is favorable To prevent the injection process of pouring the “vomit steel” phenomenon.
