    For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about 025 to 030 metric tons of slag per ton of crude iron produced Steel furnace slag production, after removal of entrained metal, will be about 10 to 15 percent of the crude steel outputSlag is the glasslike byproduct left over after a desired metal has been separated (ie, smelted) from its raw oreSlag is usually a mixture of metal oxides and silicon dioxideHowever, slags can contain metal sulfides and elemental metals While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of Slag WikipediaIron and steel slags are coproducts of iron and steel manufacturing In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent The iron ore is a mixture of iron oxides, silica, and alumina From this and the added fluxing agents molten slag and Iron and Steel Slag Statistics and Informationsteel slag can, which is why the track officials chose steel slag as the coarse aggregate for the pavement Similarly, when Colorado state transportation officials wanted to repave scenic I70 through Glenwood Canyon they chose steel slag coarse aggregate because they wanted a long lasting, stable, durable, high friction pavementhow long iron slag can be stored despiegelkamernlSteel slag can also be produced by smelting iron ore in a basic oxygen furnace According to methods for cooling molten steel slag, steel slag is classified into five types: natural aircooling steel slag, waterspray steel slag, waterquenching steel slag, airquenching steel slag, and shallow box chilling steel slag Steel Slag an overview ScienceDirect Topics

      We looked specifically at ferrous slag, the leftover material from the smelting of iron and steel, in the ChicagoGary area of Illinois and Indiana Ferrous slag is currently underutilized Although the construction industry does use some slag as an aggregate, most is simply discarded However, slag could be used to treat acid soils or acid mine drainage Doing so would both offset the cost of Open SLAG Storage – SLAG is an Industrial Waste Product SLAG is an industrial waste product – there is no standards about the quality of it What is in it depends on what was the raw material used for the production of iron – eg scrape metal, iron ore, Orcem claims that absolutely none of the Orcem’s material or products are toxic But Material Safety Data Sheets for GGBFS from The Health Risk of SLAG – an Industrial Waste Product Molten slag is collected in iron slag pots during the melting of raw materials in the electric arc furnace The slag is then cooled by pouring it into the designated area TXI, the Texasbased US cement firm, developed and patented a method which allows this EAF slag to be used in the manufacture of high quality cement Such use of slag conserves resources and reduces energy consumption as Various types of cooling methods of EAF steel slag to be   To get a date from slag you need to have thermoluminescence testing done, and that is not cheap Not worse than AMS carbon dates, though Around $500$1000 a pop depending on what the lab has to do to prep it The Euro guys go nuts with slag colors, but all they mean is iron content (which relates to smelt efficiency)Archaeological slag: can someone tell me what was going on All low hydrogen stick electrodes should be stored properly, even those with an "R" suffix Standard EXX18 electrodes should be supplied to welders twice per shift Moisture resistant types may be exposed for up to 9 hours When containers are punctured or opened, low hydrogen electrodes may pick up Storing and Redrying Electrodes lincolnelectric
