Scrap Specifications
- 1. ArcelorMittal Dofasco Scrap Specifications December 2010
- 3. Scrap Specifications - Rejections Scrap composition conformance is critical to ensuring that ArcelorMittal Dofasco maintains its reputation as a superior supplier of high quality flat rolled steels. Material that does not meet our design criteria will be rejected . Rejections may also occur as the result of identified processing deficiencies related to scrap. (i.e.: Mixed loads) Processing deficiencies may only become apparent after an intermediate component is further processed or the finished product is in use. These requirements are detailed in our scrap specifications. Scrap rejections can occur when the design criteria of each individual scrap type are not met. Scrap rejections could also occur at any time that the product is on ArcelorMittal Dofasco property. ArcelorMittal Dofasco personnel (scrap inspectors) react to a stringent set of guidelines, specifically designed to reinforce the acceptance of a quality product. Any product that does not meet this criteria, will be rejected and a non conformance report issued. Specific follow up on the non conformance coupled with the severity of the non conformance could result in the levy of a reloading/handling charge ($400.00 fixed charge) and further action could be determined to be suspension or termination of said supplier to ArcelorMittal Dofasco.

- 63. Rebar Specification Description All rebar scrap must be prepared in a fashion that insures efficient magnet handling and compact furnace charging. Shipments must not contain badly tangled material, or material that would tend to become badly tangled, during loading, in amounts that would appreciably increase material handling or furnace charging times (by comparison to average shipments of the same grade.) If the maximum piece size and minimum bulk density requirements given in Arcelormittal Dofasco's grade-by-grade Specifications are met, the scrap should be acceptable. However, the principles of efficient magnet handling and compact furnace charging override the specific size and density requirements given in the grade-by-grade specs. Off-Spec rebar will not remain on ArcelorMittal property . ArcelorMittal Dofasco does not have the ability or the resources available to reload tangled rebar. Shipper will be responsible (at their costs) to reload material using their own equipment and resources.
