Aluminum Plant Outage

A major aluminum manufacturer contracts Horner EMDS (Electro Mechanical Diagnostic Services) to perform monthly vibration data collection and analysis. EMDS identified a mill gearbox input shaft bearing issue. In 2022, the monthly vibration analysis indicated the bearing issue increasing. The vibration analysis was discussed with the customer and the vibration data collection increased to twice weekly. At the same time, customer was planning a major outage to on-site repair the gearbox. The March outage was scheduled. Horner provided 24 hour per day, 5-day work schedule. On a Monday the outage started. Mark Rosebrock was lead tech on day shift and Matt [...]

Aluminum Foil Plant Preventative Maintenance

One of Louisville’s largest customers pro- duces aluminum foil. Manufacturing foil starts with aluminum rolls up to 1/2” thick. This plant takes the ½” thick thru mill 6, which reduces the foil thickness to less than 0.100” thickness. From mill 6, the rolls are rolled thinner in mills 3-4-5. After several passes thru these mills, the rolls go to mill 1-2 to roll to thickness required for commercial or residential use. Standard household or standard duty aluminum foil is 0.00063” thick and extra heavy duty foil is 0.00094” thick. Both thinner than 1 thousandth of an inch. Rolling aluminum foil this [...]

Catastrophic Bearing Failure

An Aluminum Foil manufacturer experienced catastrophic bearing failure on a combustion air furnace fan. When the bearings failed, the fan wheel made contact with the fan housing. The combustion air fan provides air to the furnace gas burners. The furnace heats the aluminum foil rolls to burn off the oil used to manufacture aluminum rolls when the aluminum passes through mills and separators. Horner Fan received the damaged fan. The incoming inspection revealed the fan hub was cracked and along with the fan wheel damage – bent/cracked blades and ripped off back plate, Horner Fan recommended to manufacture a replacement. The [...]
