冷床主要有拔齒式冷床、齒條步進式冷床、撥爪式冷床、運載鏈式冷床、滾盤式冷床等。

將已軋制成型產品通過輥道輸送進入冷床，再由齒條步進式拔齒等形式，將排列在冷床上的工件逐步移向冷床頂端，達到了工件的冷卻效果。

The main bed tooth pulling type cooling bed, rack step type cooling bed, poking claw type cooling bed, carrier chain cooling bed, rolling disc cooling bed etc..

The rolling molding products through the conveyor into the rack cooling bed, stepping teeth and other forms, will be arranged in workpiece cooling bed is gradually moved to the top of the bed, the cooling effect of the workpiece.

使冷床區(qū)域產生空氣自然對流，形成煙囪效應，造成冷床上圓鋼下部冷卻速度過快，出現(xiàn)冷卻不均勻，影響了產品的質量。步進翻轉冷床利用步距與齒距的差值，使圓鋼在冷床上每移動一個齒距，圜鋼就滾動了一個角度，避免了圓鋼在冷床上的不均勻冷卻所造成的質量問題。Application:bedismainlyusedintheironandsteelindustry,metallurgicalindustry,etc。

The cooling bed area of air natural convection, the formation of a chimney effect caused by the cooling bed bar lower cooling speed, appear uneven cooling effect of the quality of the products. Step by step difference of inverted cooling bed and pitch, the bar in the cooling bed every movement of a pitch, round steel rolling an angle, to avoid quality problems of round non-uniform cooling in the cooling bed caused by.

二小型作業(yè)區(qū)型材改造試生產過程中，通過冷床裙板自重式防止角鋼傾翻裝置的設計及應用，在小角鋼的收集過程中，省去了在移鋼小車處人工將角鋼翻正操作，壓縮了了冷床輸出的時間，有效防止因角鋼傾翻而影響鋼材的輸出節(jié)奏，實現(xiàn)了冷床正常穩(wěn)定的下鋼。

Two small work area profile transformation  production process, prevent the inclination angle of design and application of double bed apron device by gravity, in the process of collecting small angle, eliminating the need for moving steel trolley artificial angle righting operation, the output of the compressed cooling bed time, effectively prevent tilting angle and effect of output rhythm of steel, the steel cooling bed under normal and stable.

拉鋼式和往復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）以使用鏈式冷床較好，上鋼一廠、大連鋼廠的650軋鋼車間都采用鏈式冷床，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。二小型作業(yè)區(qū)型材改造試生產過程中，通過冷床裙板自重式防止角鋼傾翻裝置的設計及應用，在小角鋼的收集過程中，省去了在移鋼小車處人工將角鋼翻正操作，壓縮了了冷床輸出的時間，有效防止因角鋼傾翻而影響鋼材的輸出節(jié)奏，實現(xiàn)了冷床正常穩(wěn)定的下鋼。兩種鏈式冷床使用單位反映都較好。

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.
