中文摘要：
钛合金平板的连续、方向性的团结的实验用设计作者的多功能被执行有矩形的冷坩锅的方向性的团结仪器。在团结的平板的表面质量上处理参数的影响被学习。平板表面质量能有效地与在卷和输入电源拐弯增加，并且与 latively 退却速度和 re 减少被改进，这被显示出到感应线圈的柱脚的 Iow 位置。在下降顺序的处理参数的影响如下：在卷，输入电源，退却速度和柱脚的相对位置的拐弯。与优化参数，从裂缝和涟漪免费的优秀平板被获得。有好表面质量的团结的结构显示出方向性地团结的结构。
英文摘要：
Experiments of continuous and directional solidification of titanium alloy slabs were performed using authors-designed multi-function directional solidification apparatus with rectangular cold crucible. Influences of processing parameters on the surface qualities of the solidified slabs were studied, It is shown that the slab surface qualities can be effectively improved with increasing of the turns in coil and input power, and with decreasing of withdrawal velocity and relatively low position of pedestal to the induction coil. The influences of the processing parameters in the descending order are as follows： the turns in coil. input power, withdrawal velocity and the relative position of pedestal. With optimized parameters, quality slabs free from cracks and ripples were obtained. The solidified structure with good surface quality shows directionally solidified structure.
