| 摘 要： | 用数值模拟的方法研究了连续式加热炉内钢坯的加热过程,分析了滑轨结构、滑轨高度和滑轨材质等对钢坯黑印温差的影响,为消除钢坯黑印、提高钢坯加热质量提供了理论依据。结果表明,使用孔桥式全热滑轨时钢坯黑印最小,且随孔洞个数增加,黑印温差逐渐降低;黑印温差与滑轨高度基本呈双曲函数关系,当滑轨达到一定高度时,继续增加轨高对黑印温差的影响已不明显;滑轨材质对钢坯黑印基本无影响。

| Abstract: | The methods combined by test, field monitoring and theoretical analysis were adopted to do the systemic research on the rock mass from micro structure to macro deformation, and rheological model of Jinchuan rock mass was established to discuss the reasonable supporting time. Results show that supporting after suitable stress and displacement release can benefit for the long term stability of surrounding rock. |
