    摘要： According to the invention, oil-charged mill-scale is treated such that the oil is encapsulated or bound therein. An escape of oil on use in a shaft oven first occurs when the ignition point is reached, thus guaranteeing combustion. Agglomeration of said mixture is by pelleting. A mixture comprising the following is preferably used for encapsulation and chemical binding of the oil: A zinc salt and a calcium salt of a saturated or unsaturated fatty acid, a hydrophobic inducing agent, an amino alcohol and ammonia. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b), “A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims.” Therefore, the abstract is not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.
