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。

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 disparity, so the type of cooling bed steel workshop are diverse.

保证合理有序的过钢节奏，加大矫直测量次数，确保矫直中心在一条直线上。制定矫直辊装配标准，保证安装正确，有据可查。建立BH值与矫直辊间距的关系，做到合理配辊，保证辊缝在1－3mm之间。

Ensure a reasonable and orderly flow of steel rhythm, increase the number of straightening measurement, to ensure that the straightening center in a straight line. The assembly standard of straightening roller is set up to ensure that the installation is correct and can be checked up. The relati***hip between the BH value and the spacing of the straightening roller is established, and a reasonable roll matching is made to ensure the gap between 1 and 3mm.

处理后的线材强度可以等于或大于铅浴淬火者的强度，这是其他各种线材轧后控冷索氏体化处理方法所不及的。其他优点是冷却温度比较均匀，温差不大于5～10℃，而且不具有粘着性，不会像铅浴或盐浴处理时出现挂铅、挂盐现象。

The strength of the treated wire can be equal to or greater than that of the lead bath quenched. This not enough for all kinds of wire rod after cooling suxhnite treatment. Other advantages are that the cooling temperature is more uniform, the temperature difference is not more than 5~10 degrees C, and it does not h***e the adhesion, and it will not appear as lead or salt hanging during the lead bath or salt bath treatment.
