1. In high-speed aluminum foil rolling, it is difficult to avoid the high concentration of oil vapor bai around the rolling mill. In order to reduce the concentration of oil vapor as much as possible, the normal operation of the smoke exhaust device should be ensured, and the exhaust volume should reach the maximum.
2. Strengthen the spot inspection and inspection of the oil mist lubrication system of work rolls, support rolls and guide rolls to ensure that the oil mist generator oil level, oil pressure, wind pressure and temperature meet the requirements, and the connecting pipeline between the oil mist generator and the bearing box Should be unblocked to provide adequate lubrication conditions. Poor oil mist lubrication is one of the main reasons for rolling mill fires. In production, the oil mist lubrication system should be focused on management, and the problem should be stopped in time.
3. Strengthen the inspection and management of the inner ring and bearing of the roll, check each time the roll is changed, and repair and replace the faulty parts in time. The installation tightness of the bearing box should be moderate to avoid relative movement between the roller neck and the bearing inner sleeve.
4. Where there is oil vapor, explosion-proof electrical equipment must be used, and the power of the spreader should be cut off in time after the crane spreader is removed.
5. The tape break protection device should be sensitive and effective, and the thickness of the aluminum foil blank should be uniform, and no sudden thickening is allowed to avoid the occurrence of jamming. In operation, the rolling mill speed should be appropriately reduced at the end of the coil.
6. Improve the operation level, reduce the broken belt, clean up the broken aluminum pieces in the rolling mill body and the oil collecting pan in time, and the rolling mill body and pipeline oil tank should be well grounded.
7. Reasonably choose base oils and additives. In addition to the good lubricity, cooling, fluidity, annealing performance, stability, and no unpleasant odor, the rolling oil of high-speed aluminum foil also has the difference between base oil and additives, two or more additives. It must have good compatibility and not easily deteriorated.
