The author believes that there are two important routs for steel slag largescale utilization in China where industrialization is accelerating: one is to produce cement and concrete using the steel slag fine powder after reclaiming waste steel; the second is direct application in road and hydraulic construction.

The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.

manufacture of stainless steel, only a few investigations have been conducted. Morbidity studies show no evidence of adverse effects on respiratory health in workers engaged in the melting stages of stainless steel production which might be associated with chromium exposure, although the available data preclude wider
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 1600 ...
But let''s look at AOD process, once steel scrap are all melt then like normal carbon steel, decarburization is necessary. However, this stainless steel contains high amount of chromium so just direct blowing of oxygen will cause oxidation of chromium, and it is close to slag phase This increases production cost of stainless steel a lot.
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.. Powder metallurgy is also used to make unique materials impossible to get from melting or ...
