The extraction of glycyrrhizin from licorice root and stolon with ethanol/water solutions leaves a lignocellulosic residue, which could be potentially applied in biocomposites. This process proved difficult in principle, given the considerable hardness of this material as received, which impedes its use in polymer resins in large amounts. After ball milling, up to 10% of this fibrous residue

Secondary Refining For purposes of this article, Secondary Refining or Secondary Metallurgy is defined as any post steelmaking process performed at a separate station prior to casting and hot metal desulfurizaion. It does not include normal alloying prac tice in
Lime is an integral part of the steelmaking process and is added as a fluxing agent. The volumes required vary according steelmaking processes: Lhoist advises that every tonne of steel manufactured requires 30-70kg of lime, and 100-200kg of limestone; the World Steel Association notes that for BOF steelmaking, 300kg of limestone is required per tonne of steel.

GRANSHOT IN STEELMAKING Synchronizing a blast furnace, BF, which strives for maximum stability, with a BOF steel plant, which is operated batch–wise and has to produce various steel grades and dimensions, is difficult and sometimes seemingly
90 Of Manganese Ore Used In Steelmaking - Lametars 90% of manganese ore used in steelmaking. Manganese, is the fourth most used metal in the world after iron, aluminum and copper. It is never used in its own right as a pure metal, but it’s an important raw
BOF sludge is collected from wet cleaning system in steelmaking plants. It is composed of not only valuable iron but also impurities like Zn, Pb, and some alkaline oxides [ 1 , 2 , 3 ]. Traditional landfill treatments inevitably result in environmental pollution because of the contained heavy metal and the high pH values of water-absorbed soil [ 4 , 5 ].
Energy optimizing furnace (EOF) is a furnace for the primary steelmaking. The steelmaking process in the EOF was developed by the mini steelworks pioneer Willy Korf along with his colleagues. The process is operating at the GERDAU Divinopolis plant in Brazil and at JSW SISCOL plant and at Hospet Steel plant of Mukand in India.

The BOF slag used in this study originated from the steelmaking furnace areas of the China Steel Corporation (Taiwan); the aggregates (g ranite) were provided from a local asphalt plant. The BOF slag was used as the substitute of coarse aggregate.
The detail modifiion is building the additive amount model of BOF slagging constituent at one set industrial PC. This program is very convenient to use, and its expression is very intuitionistic. The most important is this model has very good guiding for the steelmaking operating, also it has partly “Auto Steelmaking” function.
Basic oxygen furnace for steel making
29/11/2013· Mill scale is an iron oxide waste generated during steelmaking, casting and rolling. Total generation of mill scale at JSWSL is around 150 t/day and contains 60–70%FeO and 30–35%Fe 2 O 3 . To recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace; however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.
2 Introduction to Basic Oxygen Steelmaking Basic oxygen steelmaking (BOS) is the most widely used process for producing crude steel from molten pig iron (hot metal). The process involves blowing oxygen through hot metal to reduce its carbon content by
