摘要

Over the last eight years significant automation enhancements were made at ArcelorMittal's Burns Harbor Steel Producing shop for the three BOF vessels, the secondary processing stations and the two slab casters. These automation improvements have led to increased production by 6% and a shop yield increase from 86.0% to 91%. Working ratio during this time period increased from 69.3% to 77.9%. Quality improvements from automation include improving plate rejects by 53.1% and reducing plate reprocessing 23.1%. Overall cost per ton has decreased by 27.6%. Most importantly the automation changes have decreased the OSHA injury rate from 0.84% to 0.45% and the all-injury rate from 7.22 to 4.57.
