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.冷床取樣要使用專用工具進(jìn)行取樣。

4.作業(yè)中應(yīng)注意觀察周圍的情況，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，確保冷床周圍的環(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。

保證合理有序的過(guò)鋼節(jié)奏，加大矯直測(cè)量次數(shù)，確保矯直中心在一條直線上。制定矯直輥裝配標(biāo)準(zhǔn)，保證安裝正確，有據(jù)可查。建立BH值與矯直輥間距的關(guān)系，做到合理配輥，保證輥縫在1－3mm之間。

Ensure a reasonable and orderly flow of steel rhythm, increase the number of straightening measurement, to ensure that the straightening center in a straight line. The assembly standard of straightening roller is set up to ensure that the installation is correct and can be checked up. The relatihip between the BH value and the spacing of the straightening roller is established, and a reasonable roll matching is made to ensure the gap between 1 and 3mm.

工藝過(guò)程是：線材出精軋機(jī)后先入水冷導(dǎo)管進(jìn)行急冷，冷卻到650～750℃，經(jīng)成圈器成圈后落入流態(tài)床中。其他優(yōu)點(diǎn)是冷卻溫度比較均勻，溫差不大于5～10℃，而且不具有粘著性，不會(huì)像鉛浴或鹽浴處理時(shí)出現(xiàn)掛鉛、掛鹽現(xiàn)象。流態(tài)床用流動(dòng)的、導(dǎo)熱性好的粒料(鋯砂，含ZrO267.2%；SiO232.8%)作媒介，用鼓風(fēng)機(jī)攪動(dòng)這些顆粒呈懸浮運(yùn)動(dòng)狀態(tài)，如同鉛浴池中的鉛液沸騰一樣。

The process is as follows: after the wire is finished, the first step is to enter the water cooling pipe and then to cool it to 650~750 degrees. The flow bed is used as a medium for flowing, good thermal conductivity particles (zirconium sand, containing ZrO267.2%; SiO232.8%). The particles are stirred by the blower to move in suspension, just as the lead liquid in the lead bath is boiling.
