冷床价格高性价比的选择

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.

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。

It cists of cooling bed and lifting baffle, roller, steel tr***ersing trolley device, stepping into the steel group, rack cooling bed, transferred to the steel cooling bed device by tr***ersing trolley, moving rack each into a cycle of steel means a steel dial to static rack, the circular steel group one by one assigned to each tooth, because of high temperature steel cooling bed.

拉钢式和往复多爪推齿式两种冷床对于圆钢都不太适用，容易拉斜、滚乱。冷却圆钢（管坯）以使用链式冷床较好，上钢一厂、大连钢厂的650轧钢车间都采用链式冷床，两者所不同之处在于：上钢一厂的圆钢搁在台架上，链条拉着圆钢缓慢前进，由于圆钢单重较大，一般不会乱滚。拉钢式冷床，其特点是利用单爪绳式或链式拉钢机，横向成批拖运轧件。大连钢厂的圆钢直接搁在链条上，前进过程中圆钢与链条无相对运动。两种链式冷床使用单位反映都较好。

The two kinds of cooling beds, pulling steel type and reciprocating multi tooth type, are not very suitable for round steel. Cooling round steel (Guan Pi) to use the chain type cold bed is better, the 650 steel mill of Shanghai steel factory and Dalian steel mill use chain cold bed. The difference lies in that the round steel in the first steel plant is on the bench, the chain pulls the round steel slowly forward, because the single weight of the round steel is larger, it will not roll out. The round steel of Dalian steel plant is directly placed on the chain, and there is no relative movement between round steel and chain during the progress. The use unit of the two types of chain cold beds is better.
