experimental results show that the system is provided with good human-machine interface, high retrieval rate, short retrieval time and can well satisfy the user's requirements 实验结果表明:该系统交互性好,检索准确率高,检索时间短,能较好地满足用户的要求。
slag ball's shape is ball with grooves on the surface . this kind of productions can decrease the thickness of slag layer, improve the rate of metal retrieval rate, which make it be used widely 挡渣球外形为带沟槽球形的结构,能使钢包中渣层厚度减小,金属收得率提高,故得到广泛应用。
