該冷床設(shè)備主要用于軋后鋼板在線緩慢自然冷卻。在型材生產(chǎn)線上，冷床對型材還具有預(yù)彎曲功能，防止型材在自然冷卻過程中因各處質(zhì)量不等導(dǎo)致出現(xiàn)不規(guī)則彎曲。應(yīng)用領(lǐng)域：冷床主要應(yīng)用在鋼鐵行業(yè)、冶金行業(yè)等。

With the cooling bed equipment is mainly used for rolling steel platesonline slow natural cooling. Profile production line has the function of cooling bed pre bending profiles, prevent profiles in the natural cooling process of the entire qualityranging from lead to irregular bending. Application: bed is mainly used in the iron and steel industry, metallurgical industry, etc.

當(dāng)流態(tài)層溫度為250℃時，奧氏體分解溫度為550～600℃，同鉛浴淬火相似；當(dāng)流態(tài)層溫度為300℃時，奧氏體分解溫度約為500℃左右，比鉛浴淬火還低。

When the temperature of the flow layer is 250 C, the austenite decomition temperature is 550~600, similar to that of lead bath quenching. When the flow state temperature is 300, the austenite temperature is about 500 C, which is lower than the lead bath quenching.

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.

拉鋼式和往復(fù)多爪推齒式兩種冷床對于圓鋼都不太適用，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架上，鏈條拉著圓鋼緩慢前進，由于圓鋼單重較大，一般不會亂滾。大連鋼廠的圓鋼直接擱在鏈條上，前進過程中圓鋼與鏈條無相對運動。Whenthetemperatureoftheflowlayeris250C,theaustenitedecomitiontemperatureis550~600,similartothatofleadbathquenching。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.
