How ArcelorMittal shortens lead times for maintenance of segments

Metal Challenge #1: Unexpected bearing failure

Bearings that fail without warning can cause costly downtime.

Metal Challenge #3: Bearings fail due to mounting errors.

Wrong mounting of roll neck bearings might cause damage to the roll neck or the inner ring raceways. The result is failing bearings.

Metal Challenge #4: Decarbonisation demands

Legislators put higher and higher demands on the metal industry to decrease CO₂ emissions. SKF helps to meet the demands with remanufacturing – and not only bearings.

Metal Challenge #5: The high costs of replacing large bearings

To keep maintenance budgets low, many customers look for alternatives to replacing used bearings with brand-new ones.

Metal Challenge #6: Increase output and machine performance

All components in the continuous caster machine are interlinked. To increase output, they all must work together and support the whole system.

Metal Challenge #7: Premature roll neck bearing failures

When you mount traditional roll neck bearings with spacers, there is a risk of mixing components. That might result in the wrong bearing clearance and subsequent failure.

Metal Challenge #8: It’s hard to determine the condition of bearings

Bearing positions that aren’t covered by a condition monitoring system also need to be monitored

Metal Challenge #10: Cut cost per ton

Planned and unplanned downtime increases cost per ton. Solutions and services from SKF help customers to reduce both.

Metal Challenge #12: Increased risk of bearing failure due to increased load and speed

When you increase output by increasing load and speed, you need to find a way to mitigate the higher risk of bearing failure.

Metal Challenge #16: High costs due to long unplanned downtime

Each minute you can keep running means lower costs and better margins.

Metal Challenge #17: Steel contamination due to leaking lubricant

Getting lubricant onto the material can make the end product impossible to process, so the material must be scrapped.

Metal Challenge #18: Grease in cooling system creates high costs

When grease gets in the cooling system, significant costs come with it. Water treatment, filter changes, and maintenance all add up, not mentioning health and safety issues.

Metal Challenge #19: Identifying optimal maintenance routines

Optimizing the maintenance program helps optimize machine performance, but many factors must be considered.

Metal Challenge #1: Défaillance prématurée des roulements

La défaillance des roulements du jour au lendemain peut entraîner des arrêts-machines coûteux.

Metal Challenge #12: Augmentation du risque de défaillance des roulements due à l’augmentation des charges et de la vitesse

Lorsque vous augmentez les charges et la vitesse afin d’accroître votre production, vous devez trouver une solution afin de limiter le risque accru de défaillance des roulements.

Metal Challenge #19: Trouver des routines de maintenance optimales

L’optimisation du programme de maintenance contribue à l’optimisation des performances des machines, mais il y a de nombreux facteurs à prendre en compte.
