冷床下料裝置將其收集成組送至輸出輥道上, 再由輸出輥道將其送到冷剪剪切成定尺成品。冷床的設(shè)計(jì)質(zhì)量與安裝精度直接決定著產(chǎn)品的終質(zhì)量。

The cooling bed feeding device collect group sent to the output roller, the roller output will be sent to the cold shear into thespecified product. Design quality and installation accuracy of cooling bed directly determines the final quality of the product.

1.軋制過(guò)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(zhuān)用工具進(jìn)行取樣。

4.作業(yè)中應(yīng)注意觀察周?chē)那闆r，無(wú)關(guān)人員嚴(yán)禁進(jìn)入大冷床的危險(xiǎn)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?chē)沫h(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。

冷床是冶金軋鋼行業(yè)對(duì)軋制產(chǎn)品（螺紋鋼、園鋼、鋼管等）有效進(jìn)行冷卻的工作臺(tái)面。冷床由機(jī)械傳動(dòng)系統(tǒng)、水冷卻系統(tǒng)、冷床工作臺(tái)面、固定支架等方面組成。冷床主要有拔齒式冷床、齒條步進(jìn)式冷床、撥爪式冷床、運(yùn)載鏈?zhǔn)嚼浯病L盤(pán)式冷床等。

The cooling bed is metallurgical industry of rolled products (steel, steel, steel and other garden) effectively cooling the work surface. The cooling bed by mechanical transmission system, water cooling system, cooling bed table, etc. of fixed bracket. 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.

當(dāng)流態(tài)層溫度為250℃時(shí)，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(shí)，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.
