Technical operation specification for finishing mill
1. the finishing mill is the key part of the high-speed wire workshop. The technical requirements and process disciplines are obviously different from those of other units, and high vigilance shall be maintained at all times;
2. the adjuster shall first prepare the caliper, sample bar and other special tools required by the finishing mill, and be familiar with the operation requirements;
3. when presetting the imported rolling guide of each Sorty, the adjuster shall first insert the sample bar between the guide wheels so that the two rollers can rotate easily until the tightness is normal;
4. before starting the machine, the guides of all sorties must be checked. If they are loose and worn seriously, they shall be adjusted, fastened and replaced in time;
5. before rolling, the machine shall be started after water is boiled. At the same time, check the water supply of the pouring trough water pipe and the tightness of the fishing line. Close the large cover before rolling;
6. the adjusters must be familiar with the rolling procedure table, master the relevant red billet size and roll gap parameters, so as to correctly adjust and ensure the stacking and pulling relationship of the finishing mill;
7. pay attention to the changes of water pressure and oil pressure under normal rolling to ensure the normal operation of finishing mill equipment.
8. after installation, the inlet and outlet guides must ensure that the rolling line is consistent. The inlet and outlet shall not contact with the roll and the gap shall not be too large;
9. the finishing mill adjuster shall inspect the hot metal detectors, detection devices, sleeve lifting devices and other equipment before and after the finishing mill to ensure that they are in normal working condition;
10. keep in touch with the main operators frequently, keep abreast of the operation of 2\\y flying shears, broken shears and other auxiliary equipment at all times, and solve the problems found in time;
11. after the variety is changed and the roll diameter is changed, communicate with the main operator in time, so as to timely adjust the rolling mill speed and the speed of pinch roll and wire drawing machine before stripping, so that the coil can pass through the mandrel smoothly;
12. during normal rolling, pay attention to the extension of incoming materials in front of the gauge and the side looper quantity, keep in touch with the intermediate rolling adjuster, and correctly adjust the material shape to ensure the rolling speed of the intermediate rolling pre finishing rolling;
13. always observe the speed of finish rolling and feeding roll, the change of holding, water penetration pressure and flow, and ensure that the temperature of finished products is controlled within the range of process requirements;
14. the adjuster must ensure the quality of finished products and roll them according to national standards.
15. pay close attention to the front and rear signal lights and various gestures between workers, and deal with various problems in time.
16. in order to ensure the quality of finished products, the principles of "one observation, two card quantity and three adjustment" shall be followed to ensure the consistency of finished products.
17. in case of steel stacking failure after finished hole, water shall be penetrated Pinch before ejecting The wire drawing machine shall be inspected at the same time to avoid secondary steel stacking;
18. ensure that the finished products are exported and laundered Water penetrator The lead runs on the same rolling line and horizontal line;
19. when changing the type and specification, align the water lead pipe at the same time And nip roll gap shall be adjusted accordingly to ensure smooth rolling;
20. it is strictly prohibited to roll low-temperature steel and black head steel without water;
21. the post workers in the finishing rolling area shall regularly observe the data changes of the caliper, timely report and deal with the problems found to the personnel of relevant departments, and ensure the accuracy of the finished product size;
22. strictly implement the process and technical operation procedures.
