The axial gap of the balancing drum and a cross channel is a cone-shaped structure with a small entrance and large exit and can prevent from being obstructed by sand flowing through the gap;
平衡鼓和交叉流道的轴向间隙为入口小、出口大的锥形 结构,防止被流经间隙的砂子阻塞;

The influence of the roll gap change and roll speed change on the exit thickness and the inter-stand tension is computed with the dynamic continuous rolling theory.
