UDC 678 . 743 : 628 . 492 - Nippon Steel Corporation

2012-9-14  with PCBs and encased in steel drums are charged into a plasma melting furnace without having to be removed from the drums, and melted and decomposed efficiently by the heat of the plasma arcs and molten slag bath working in combination. The PCBs in the upper part of a steel drum are directly heated by the plasma arcs and decomposed.

ENVIRONMENTAL RESTORATION OF A STEEL MILL

2015-10-23  Another complication was the result of the discovery that there were polychlorinated biphenyls (PCBs) present in the soil in some areas of the site. These were the result of the fact that for a brief period in the early 1970s, the mill had used hydraulic shears to cut the hot steel from the continuous caster into billets and that some of the hydraulic oil used in the shears contained PCBs. Some of hydraulic oil had entered the cooling water system and thus contaminated the mill scale with PCBs. The mill scale was periodically removed from the process water system and used as fill on the site. In1976 with the enactment of the Toxic Substances Control Act (TSCA), PCBs

Evaluation of steel slag and crushed limestone

2013-3-1  Steel slag is produced as a by-product during the oxidation of steel pellets in an electric arc furnace. This by-product that mainly consists of calcium carbonate is broken down to smaller sizes to be used as aggregates in pavement layers. They are particularly useful in areas where a good-quality aggregate is scarce.

DIOXINS AND FURANS IN IRON AND STEEL INDUSTRY

2009-6-22  Four different processes performed in iron and steel industry are known as PCDDs/PCDFs sources: sintering of iron ore, iron production (blast furnace), steel production (basic oxygen furnace) and melting of iron and steel scraps [8]. The main sources of PCDDs/PCDFs are processes occurring on a sinter strand [3,4].
