<*n style="font-size:14px;">When the temperature of the flow layer is 250 C， the austenite decomition temperature is 550~600， similar to that of lead bath quenching. When the flow state temperature is 300， the austenite temperature is about 500 C， which is lower than the lead bath quenching.<*n style="font-size:14px;">

<*n style="font-size:14px;">为适应不同型号、不同厚度的角钢，冷拉，防倾翻装置的上有一个可以随时取放配重的斗壳，这样就可以实现不同型号、不同厚度角钢在裙板处稳定下滑。

<*n style="font-size:14px;">In order to adapt to different types and different thickness of angle steel， the andumping device has a shell that can be taken and counterweight at any time， so different type and thickness angle steel can slide steadily at the skirt plate.<*n style="font-size:14px;">

<*n style="font-size:14px;">冷床是轧钢生产中重要的辅助设备。冷床的作用在于将800℃以上的轧件冷却到150～100℃以下，同时使轧件按既定方向运行，在运输过程中应保证轧件不弯曲。由于轧制产品形状繁多相差悬殊，因此，轧钢车间的冷床型式是多种多样的。

<*n style="font-size:14px;">The cooling bed is an important auxiliary equipment in steel rolling production. The bed is 800 degrees above the workpiece cooling to 150~100 DEG C， and make the operation according to the established direction， in the transport process should ensure the workpiece does not bend. Because the rolling shape of the product range of di*rity， so the type of cooling bed steel workshop are diverse.<*n style="font-size:14px;">
