本文总结了用模型实验方法研究摇包内液体的运动规律.用不同比重的液体模拟铁水,对三种不同大小的摇包模型在不同装入量、偏心距及摇转速度下,做了一系列的实验,发现摇包内液体运动规律有四种临界运动状态:平摆运动、单峰海浪波运动、多波运动及旋转抛物面运动.其中对冶金生产实际有用的为第二单峰和第四种临界运动状态,其强烈的搅拌作用促使熔池内化学反应加速进行.根据一系列的实验结果得出了计算临界转速的经验公式.在10吨摇包上用铁水(>1200°C)进行临界转速实验,结果证明,实验室研究结果与生产实际基本相符.因而,为生产操作上提供了最佳摇转制度的参考数据.
This paper summarizes the model experiment method to study the movement law of the liquid in the rocker.The molten iron with different specific gravity is used to simulate the three different sizes of rocker model under different loadings, eccentricity and rotation speed Series of experiments and found that there are four kinds of critical movement laws of liquid movement in the rocker: flat pendulum motion, unimodal wave motion, multi-wave motion and rotating paraboloid motion, of which metallurgical production is actually useful for the second single peak and the Four kinds of critical state of motion, the intense stirring effect accelerates the chemical reaction in the molten pool.According to a series of experimental results, the empirical formula for calculating the critical speed is obtained.On the basis of a series of experiments, hot metal (> 1200 ° C) The critical speed experiment results show that the laboratory research results are basically in line with the production practice, thus providing the reference data for the optimal shaking system for the production operation.
