The Operating Rules of Rolling Mills

The operating rules of the rolling mills consist of three aspects, namely the pre-production operating rules, the production operating rules, and the safe operating rules. The following is the detailed introduction.

1. Pre-production Operating Rules of Rolling Mills

(1) The contents of inspection are as follows: main rolling mill, screwdown, coiling system, working roll, support roll, guide roll, process lubricant and emulsifier, ensuring that there are no abnormal conditions in these parts, which should be eliminated in time if it is abnormal.

(2) Correct the measuring instruments, including micrometers, ensuring the accuracy of operation.

(3) Before rolling, let the rolling mill run idle for a few minutes, check if there are noise and abnormal operation, and preheat the rolls.

2. Production Operational rules of Rolling Mills

(1) When rolling steel strips, the principle of width first followed by narrowness should be followed, and clean incoming materials and neat drums should be required. Static pressure should be the main method while rolling down, and dynamic pressure should be supplemented.

(2) When the rolling mills is started and stopped, it must be stable and even. It needs to ensure tension stability, strip thickness should be measured step by step, and its quality and flatness should be observed at any time. If there are deviations or abnormalities, the rolling mill should be stopped and checked in time. If it is caused by the quality of the roll, the roll should be replaced immediately. After the replacement, the roll gap should be adjusted before it can be put into production.

(3) Before leaving work, all switches of the operating platform should be checked for reset and no omissions should be made.

3. Safe Operating Rules of Rolling Mills

(1) Operators must wear labor protection articles when handling the rolling mills.

(2) Before starting rolling mills, you must carry out the necessary inspections. You should not be sloppy. You can start after you confirm there is no mistake.

(3) During the work process, the operator can’t leave the job without authorization, and can’t do the work unrelated to the work. Cut waste should be trapped and cleaned.

(4) It is strictly forbidden to carry out the feeding operation by hand in the guide plate, and each coil of steel strip must be decelerated at the end of rolling. When the rolling is completed, be sure to turn the “curl tension” to zero before disconnecting the steel strip, otherwise, it will be dangerous.

(5) If it is necessary to carry out maintenance during work, the rolling mills must be stopped after the power is turned off. After the repair is completed and confirmed, it can be run again.
