Aluminum foil rolling must have three conditions for fire or explosion: combustibles, combustion aids, fire source and high temperature. Without any of these conditions, it will not burn or explode.

The oil vapor and oxygen in the air produced by high-speed aluminum foil rolling are unavoidable. Therefore, the key to the safety and fire prevention of high-speed aluminum foil rolling mills is how to eliminate the fire source and the high temperature caused by local overheating. The main measures are as follows:

1. In high-speed aluminum foil rolling, it is difficult to avoid the generation of high-concentration oil vapor around the rolling mill. In order to minimize the concentration of oil vapor, the normal operation of the smoke exhaust device should be ensured and the exhaust air volume should be maximized.

2. Strengthen the spot check and inspection of the oil mist lubrication system of the work roller, support roller and guide roller to ensure that the oil level, oil pressure, wind pressure and temperature of the oil mist generator meet the requirements, and the connection pipeline between the oil mist generator and the bearing box It should be unblocked to provide adequate lubrication conditions. Poor lubrication of oil mist is one of the main causes of fires in rolling mills. In production, the oil mist lubrication system should be managed in a key manner, and problems should be stopped in time to deal with them.

3. Strengthen the inspection and management of the inner rings and bearings of the rolls. Each roll change should be checked, and the defective parts should be repaired and replaced in time.

4. In the place where there is oil vapor, explosion-proof electrical equipment must be used, and the power supply of the spreader should be cut off in time after the crane spreader is removed.

5. The broken belt protection device should be sensitive and effective, the thickness of the aluminum foil blank should be uniform, and no sudden thickening is allowed to avoid the occurrence of plugging. In operation, the rolling mill speed should be properly reduced at the end of the coil.

6. Improve the operation level, reduce the broken belt, and clean the broken aluminum pieces in the mill body and the oil collection tray in time. The mill body, pipeline oil tank, etc. should be well grounded.

7. Reasonably choose base oil and additives.

8. Strict use of open flame operation system. Before using open flame operations in the fire protection area, flammable and explosive materials around the operation area should be cleaned up in time, and professional firefighters and security officers should implement safe fire protection on the site.

9. Ensure the reliability of safety fire protection devices.

10. Strengthen the education of employees. Every employee should understand the general knowledge of safety and fire prevention, the correct use of fire extinguishing equipment, fire extinguishing equipment, and keep in mind the fire alarm phone number. When a fire occurs, the fire extinguishing measures should be taken first, and the fire alarm phone should be dialed at the fastest speed to avoid delaying the fire extinguishing time.

The causes of fire accidents in the production of aluminum foil are various, including production technology, production safety management and production equipment.
