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(duì)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.

由冷床入口輥道及升降擋板、橫移小車、分鋼裝置、步進(jìn)齒條冷床、編成組的圓鋼，通過橫移小車移送到冷床分鋼裝置，動(dòng)齒條每步進(jìn)一個(gè)周期，分鋼裝置就撥一根鋼到靜齒條上，使成組的圓鋼逐根分配到每一個(gè)齒內(nèi)，由于上冷床的圓鋼溫度很高。

It cists of cooling bed and lifting baffle, roller, steel traversing trolley device, stepping into the steel group, rack cooling bed, transferred to the steel cooling bed device by traversing 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.

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。

The needle angle steel trial production of steel bed early occurrence characteristics and causes of the tilting of the work area, the guidance of technical staff  their own design to prevent angle tilting device, by measuring the cooling bed length and bed apron and bed rack distance, the selected angle to prevent tipping device  and length of use of the device's own gravity in order to achieve the stability of angle steel, smoothly into bed.

流態(tài)冷床法的基本原理是：利用一定速度的氣流吹動(dòng)沸騰床上的固體顆粒，使之處于懸浮運(yùn)動(dòng)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(shí)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.
