The finite element simulation of stress and strain of 230 mm slab with casting rate 1.0 m/ min and 3 different roller ways layout-single-point, four-point and continuous straightening have been carried out by elastoplastic finite element method. 采用弹塑性有限元分析法,对拉速1.0m/min、厚度230mm的板坯,在3套不同的辊列布置的单点矫直、四点矫直、连续矫直进行应力应变的有限元模拟。
It is obtained that maintaining liquid level stabilizing, nozzle immersing depth 400~ 600 mm and controlling casting speed~ 1.0 m/ min are favourable to optimize liquid steel pattern and promote inclusion floating off, and the rectangular tundish structure is better than circular tundish structure. 结果表明,保持中间包液面稳定,水口插入深度400~600mm,拉速~1.0m/min有利于优化钢水流场,促进夹杂物上浮;矩形中间包结构优于圆形中间包结构。
The saturation compression speed was 1 m/ min, the stop time for each 10 m increment was 2 min, and that at 60 m was 20 min. 饱和加压速度1m/min,每10m增值停留2分钟,60m深度停留20分钟。
The results show that the limit current density, the depositing rate and current efficiency increase remarkably, the depositing rate reaches to 47.33 μ m/ min, which is about 90 times as that of conventional deposition. 结果表明:采用该方法后允许使用的极限电流密度、沉积速率及电流效率均显著增大,沉积速率高达4733μm/min,是一般槽镀的90倍左右。
This will be realized in the existing one-strand configuration, by improving the equipment performance and increasing the caster speed unto 8 m/ min with a 70 mm thick slab. 这将由现存的1流配置来实现,其措施包括改进装备性能和将70mm厚铸坯的拉速提高至8m/min。

Casting starting and before stopping, the drawing speed should be reduced below 2. 0 m/ min, otherwise, the initial pressure can not be great enough to compensate the loss of the path pressure of the horizontal shrinkage compensation. 启铸和停铸前阶段,需把拉坯速度下降到2.0m/min以下,否则钢液的初始压力不足以补偿水平补缩沿程压力损失。
The results indicate that local flux is not consistent with average heat flux when the casting speed is 1.4~ 2.6 m/ min and EMS-current is 200~ 320 A. 结果表明:拉速为1.4~2.6m/min,搅拌电流在200~320A时,局部热流与平均热流变化趋势不完全一致。
This paper introduces technological features of high oriented yarn ( HOY), whose speed exceeds 6 000 m/ min, and therefore has strict requirements for spinning equipment and process. 介绍超高速纺丝(HOY)的技术特点。HOY纺丝速度超过6000m/min,对纺丝设备、工艺流程有较高的要求。
Even the relative low wire feed rate of 6 m/ min exceeds 3 times of routine TIG welding, which greatly improves the welding efficiency. 6~10m/min的送丝速度较常规TIG焊接提高了3倍以上,大大提高了焊接效率。
It was concluded that the POY produced at the spinning speed range of 2 800-3 200 m/ min had the performance indexes suitable for post-processing. 分析得出纺丝速度在2800~3200m/min时制得的预取向丝具有适宜于后加工的性能指标。
