1.轧制过程中，冷床作业人员严禁上冷床，不准在辊道、齿条上行走。
2.生产中出现乱床等事故，必须等停轧以后进行处理清出。
3.冷床取样要使用专用工具进行取样。
4.作业中应注意观察周围的情况，无关人员严禁进入大冷床的***区域。
5.因乱床等事故造成的热废品，当班必须清出，确保冷床周围的环境整洁。
1. in the process of rolling, cooling bed workers strictly on bed, don"t walk on the roller rack.
2. in the production of random beds, such as accidents, must wait after the stop rolling process to clear out.
3. bed to use a special tool for sampling sampling.
Should observe the situation around 4. operati***, unrelated pers*** non dangerous region in the cold bed.

工艺过程是：线材出精轧机后先入水冷导管进行急冷，冷却到650～750℃，经成圈器成圈后落入流态床中。流态床用流动的、导热性好的粒料(锆砂，含ZrO267.2%；由冷床入口辊道及升降挡板、横移小车、分钢装置、步进齿条冷床、编成组的圆钢，通过横移小车移送到冷床分钢装置，动齿条每步进一个周期，分钢装置就拨一根钢到静齿条上，使成组的圆钢逐根分配到每一个齿内，由于上冷床的圆钢温度很高。SiO232.8%)作媒介，用鼓风机搅动这些颗粒呈悬浮运动状态，如同铅浴池中的铅液沸腾一样。
The process is as follows: after the wire is finished, the first step is to enter the water cooling pipe and then to cool it to 650~750 degrees. The flow bed is used as a medium for flowing, good thermal conductivity particles (zirconium sand, containing ZrO267.2%; SiO232.8%). The particles are stirred by the blower to move in suspension, just as the lead liquid in the lead bath is boiling.
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.
