Consequently, even advanced methods to reduce the leachability of steel slags (Cabrera-Real et al., 2012) will not allow increased slag recycling under present legal framework conditions. To solve this problem a pyrometallurgical reduction of the slag followed by magnetic separation of the produced zero-valent metals has been suggested ...

When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils – thouhs of an inch.In the metric system, the micron(one millionth of a meter) is used.
While the grinding wheel is a hard composite material, the flap disc is basically just overlapping rectangles of sand paper. If you were to run your grinding wheel over an edge on a piece of steel, then you ran your fingernail over that spot, it would catch, since the grinding wheel will push out material at it's leading edge. This is a burr ...

In China, BOF slag accounts for about 70% of the annual steel slag production (Cheng and Yang, 2010).In the BOF process (), minor steel scrap and a large amount of molten iron from ironmaking as well as fluxes (lime/dolomite) are added into the furnace, and a 99% pure oxygen flow is applied at supersonic speed through a lance to initiate intense oxidation reactions at a temperature of …
Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...

This slag has a lower melting point than steel, so the oxygen stream can blow the liquid slag out of the cavity without affecting the non-oxidised solid steel. This exothermic reaction is a continuous process and creates a cut as the torch moves. To keep the exothermic reaction working, the cutting torch keeps the steel heated during cutting.

How The Shape of an Abrasive Affects the Surface Profile. There are four basic shapes in abrasives: angular, sub-angular, sub-rounded, and rounded. Angular abrasives have many facets, and several jagged faces and vertices. Examples of angular abrasives are crushed glass and certain types of slag. Angular abrasives are good for stripping corrosion and rust.
