冷床是中小型棒材車間不可缺少的輔助設(shè)備之一。它的功能是將軋機(jī)軋制后經(jīng)飛剪剪切成倍尺長(zhǎng)度的棒材, 輸送并卸到冷床齒條上冷卻, 使其溫度由900℃降至100 ～ 300℃。

The cooling bed is one of the auxiliary equipment in the small bar workshop indispensable. It is the function of the bar rolling mill after double length flying shear, conveying and discharging to the cooling bed rack, the temperature 900 DEG C to 100~300 C.

拉鋼式冷床，其特點(diǎn)是利用單爪繩式或鏈?zhǔn)嚼摍C(jī)，橫向成批拖運(yùn)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(yùn)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.

拉鋼式和往復(fù)多爪推齒式兩種冷床對(duì)于圓鋼都不太適用，容易拉斜、滾亂。冷卻圓鋼（管坯）以使用鏈?zhǔn)嚼浯草^好，上鋼一廠、大連鋼廠的650軋鋼車間都采用鏈?zhǔn)嚼浯?，兩者所不同之處在于：上鋼一廠的圓鋼擱在臺(tái)架上，鏈條拉著圓鋼緩慢前進(jìn)，由于圓鋼單重較大，一般不會(huì)亂滾。針對(duì)角鋼試生產(chǎn)初期冷床下鋼發(fā)生傾翻的特點(diǎn)及原因，作業(yè)區(qū)技術(shù)人員指導(dǎo)崗位自己設(shè)計(jì)制作了防止角鋼傾翻裝置，通過(guò)冷床長(zhǎng)度的測(cè)量及冷床裙板至冷床齒條距離，選定防止角鋼傾翻裝置的位置及長(zhǎng)度，利用裝置自身重力，從而實(shí)現(xiàn)角鋼的穩(wěn)定下鋼，順利進(jìn)入冷床。大連鋼廠的圓鋼直接擱在鏈條上，前進(jìn)過(guò)程中圓鋼與鏈條無(wú)相對(duì)運(yùn)動(dòng)。兩種鏈?zhǔn)嚼浯彩褂脝挝环从扯驾^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.
