1.軋制過程中，冷床作業(yè)人員嚴(yán)禁上冷床，不準(zhǔn)在輥道、齒條上行走。

2.生產(chǎn)中出現(xiàn)亂床等事故，必須等停軋以后進(jìn)行處理清出。

3.冷床取樣要使用專用工具進(jìn)行取樣。

4.作業(yè)中應(yīng)注意觀察周圍的情況，無關(guān)人員嚴(yán)禁進(jìn)入大冷床的危險區(qū)域。

5.因亂床等事故造成的熱廢品，當(dāng)班必須清出，確保冷床周圍的環(huán)境整潔。

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.

Waste heat 5. bed because of chaos caused by the accident, the duty must be clear, to ensure the surrounding environment clean bed。

拉鋼式冷床，其特點是利用單爪繩式或鏈?zhǔn)嚼摍C(jī)，橫向成批拖運軋件。這種拉鋼機(jī)往往配備有潛行裝置，以達(dá)到有選擇性地拖運某一根（束）軋件的目的。潛行裝置有兩種形式：一種是杠桿式，另一種是滑塊式。

Pulling type cooling bed is characterized by single rope or chain machine, horizontal rolling batch haulage. This kind of steel are often equipped with stealth device to selectively hauling a workpiece to root (beam). There are two forms of the lurking device: one is leveraged, the other is a slider.

矯直板位于冷床入口側(cè), 由制動裙板拔入的軋制棒材首先落到矯直板上, 使棒材保持大平直度。矯直板每塊長1. 15m, 寬250mm , 上有10個齒形, 塊與塊之間只留出動齒條移動間隙, 安裝在定支架上。

The straightening plate is located on the inlet side of the cooling bed, and the rolled bar pulled by the brake apron first falls on the straightening plate to maintain the maximum flatness of the bar. The straightening plate is 1. 15m long and 10 250mm wide. There is only a movable clearance between the block and block, which is installed on the fixed support.

流態(tài)冷床法的基本原理是：利用一定速度的氣流吹動沸騰床上的固體顆粒，使之處于懸浮運動狀態(tài)，依靠煤氣在流態(tài)層中的燃燒，使流態(tài)層具有要求的溫度，線材從中通過時冷卻，完成奧氏體的分解轉(zhuǎn)變。

The basic principle of the flow state cold bed method is that the solid particles on the fluidized bed are blown by the flow of gas at a certain speed, so that it is in the state of suspended motion, depending on the combustion of gas in the flow state, the flow layer has the required temperature, and the wire is cooled when it passes through, and the  and transformation of the austenite is completed.
