Problems solved by technology

However, in addition to being inefficient and expensive, such processes for recovering iron from rolled scale are typically accomplished with only relatively clean scale compared to the systems and methods disclosed herein
Oily and grease-laden steel mills, which have accumulated in large quantities worldwide over decades, are not well suited for these methods because the binders do not work well with these materials

Embodiment Construction

[0036] The concepts disclosed herein are also believed to be ideally suited for the recycling of iron fines but are not limited to the recycling of iron fines. In contrast to previous recycling methods, the techniques described herein are applicable to clean or oily / grease-laden fines and combinations thereof. The disclosed bulk packaging is believed to be less costly; the fabrication method is believed to be simpler, faster and scalable. It is believed that the principles disclosed are economically applicable to a wide variety of inclusions or containers (e.g., capsules), sizes (e.g., 6 inches to several feet in diameter, accommodating single loads from under 100 pounds per capsule to several tons) and different Shapes, including, but not limited to, sphere-like, "sandbag", elongated cylinder, and sausage-like. Different shapes can even be tied or strung together similar to a string of pearls or a bunch of bananas. For example, the blast furnace operator is thus provided wi...

Abstract

A metallurgical process involves providing an ingredient enclosure and placing a plurality of granules of a first material in the ingredient enclosure. The first material contains a first ingredient in a metallurgical process. A metallurgical process furnace having a chamber in which ingredients for the metallurgical process are added is provided and the ingredient enclosure and the first material are added to the chamber. The chamber is heated after the addition of the ingredient enclosure and the first material to the chamber, although it may also be heated prior to such addition. In one form, the granules comprise mill scale and the metallurgical process furnace is a blast furnace.

Description

technical field [0001] none Background technique [0002] This patent application is related to the inventor's earlier U.S. Provisional Application Nos. 60 / 578,956 (filed June 12, 2004), 60 / 604,364 (filed August 24, 2004), 60 / 628,599 (filed November 2004), 17th application), 60 / 633,614 (December 06, 2004 application), all of which are incorporated herein by reference. Among other things, this application describes methods, apparatus and techniques for reintroducing iron-rich mill scale back into alkaline iron and / or steel processing streams whereby valuable economic and environmental benefits can be obtained . Mill scale (essentially iron oxide) is an often poorly developed but extremely available by-product of standard production procedures. In this application, there is provided information on a method for introducing rolled steel (or other materials, including other waste) into conventional blast furnaces (Blast Furnace, BF) or other metallurgical processes (such as ma...
