[建] contraction joint
shrinkage joint
shrinkage joint
- 从窄缝挑坎收缩段水流的连续方程和能量方程入手，推导出了水流出射角的计算公式。
Based on the continuity equation and the energy equation in hydromechanics, a computing formula about outflow angle of jet flow on the slit-type bucket is proved. - 相对而言，随着窄缝收缩比的减小，水垫塘冲击荷载略有减小，但同时起挑水头增加。
Comparatively, with the reducing of shrinkage ratio of slit, the shock loads of receiving pool reduce, but the critical hydraulic head that just can cause deflecting heightens simultaneously. - 以提高连铸板坯质量为研究重点，对该流程铸坯氮含量控制、钢水洁净度、二冷配水模型、铸坯辊缝收缩等进行了全面基础试验工作。
The nitrogen content of slabs, cleanliness of molten steel, mode of secondary cooling water distribution, roll gap reduction scheme etc. were studied in the line in order to improve slab quality.
