Aluminum foil rolling process fire safety measures
Foil rolling fire or explosion must have three conditions: combustible materials, such as rolling oil, cotton, rubber hose, etc; comburent that oxygen in the air; fire and high temperatures, such as friction, sparks, static electricity, fire, etc. Missing one condition which will not burn a fire explosion.
Steam and air speed foil rolling generated oxygen is inevitable, therefore speed aluminum foil rolling mill fire safety the key is how to eliminate sources of ignition and high temperatures generated by local overheating. The main measures are as follows:
In the high-speed aluminum foil rolling, resulting in high concentrations of oil around the mill steam is difficult to avoid, in order to minimize the concentration of oil vapor, should ensure the normal operation of the exhaust system, and it reaches the maximum amount of exhaust
Strengthening inspection and inspection work rolls, support rolls, guide rolls mist lubrication system to ensure mist generator oil level, oil pressure, air pressure and temperature to meet the requirements, oil mist generator and the connecting pipe bearing housing should be smooth , to provide adequate lubrication.
Strengthen inner rolls, inspection and management of the bearing, each time you change the roll should be checked for faulty repairs and replacement parts in a timely manner. Bearing box installation tightness should be moderate to avoid roll neck and bearing sleeve relative motion.
In the oil vapor place, explosion-proof electrical equipment must be used, after removing the crane spreader spreader should be promptly cut off the power supply.
Breaking with a protective device should be sensitive and effective, billet aluminum foil thickness should be uniform, it does not allow the plug to avoid sudden thickening of the many material phenomenon. In operation, at the end of the roll should be appropriate to reduce the mill rate
Improve operating standards and reduce thrust belt, clean the body and set the mill crushed aluminum oil pan, rolling body, pipes tanks etc. should be grounded.
