1.轧制过程中，冷床作业人员严禁上冷床，不准在辊道、齿条上行走。

2.生产中出现乱床等事故，必须等停轧以后进行处理清出。

3.冷床取样要使用专用工具进行取样。

4.作业中应注意观察周围的情况，无关人员严禁进入大冷床的***区域。

5.因乱床等事故造成的热废品，当班必须清出，确保冷床周围的环境整洁。

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。

使冷床区域产生空气自然对流，形成烟囱效应，造成冷床上圆钢下部冷却速度过快，出现冷却不均匀，影响了产品的质量。步进翻转冷床利用步距与齿距的差值，使圆钢在冷床上每移动一个齿距，圜钢就滚动了一个角度，避免了圆钢在冷床上的不均匀冷却所造成的质量问题。使冷床区域产生空气自然对流，形成烟囱效应，造成冷床上圆钢下部冷却速度过快，出现冷却不均匀，影响了产品的质量。

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 ***oid quality problems of round non-uniform cooling in the cooling bed caused by.

明确轴向位置，加大矫直压力。不要单独打8辊轴向，调整侧弯时应以每相临的3个辊为一个调整单元，保证矫直稳定性。侧壁斜度的处理措施是经常注意检查各辊轴向位置，窜动情况。注意在不同间隙情况下，矫直力的选取。对H2与H3的测量做到每批抽查，以做到及时调整。尽可能的使型钢完整进入水区，加强现场通风，保证型钢进入水区前温度小于400℃。

The axial is clearly defined and the straightening pressure is increased. Do not play the 8 roll axis alone. When adjusting the side bend, 3 rolls per phase should be used as an adjustment unit to ensure the straightening stability. The treatment of side wall slope is to check the axial and movement of each roll. Pay attention to the selection of maximum straightening force under different clearance conditi. The measurement of H2 and H3 is done in each batch, so as to adjust it in time.

处理后的线材强度可以等于或大于铅浴淬火者的强度，这是其他各种线材轧后控冷索氏体化处理方法所不及的。其他优点是冷却温度比较均匀，温差不大于5～10℃，而且不具有粘着性，不会像铅浴或盐浴处理时出现挂铅、挂盐现象。

The strength of the treated wire can be equal to or greater than that of the lead bath quenched. This not enough for all kinds of wire rod after cooling suxhnite treatment. Other advantages are that the cooling temperature is more uniform, the temperature difference is not more than 5~10 degrees C, and it does not h***e the adhesion, and it will not appear as lead or salt hanging during the lead bath or salt bath treatment.
