Sand For Concrete From Steel Mills Induction Furnace
The purpose of this study is to utilized this waste as useful building material, save the steel mills from transport and disposal problems. In place of river sand, alternate sand may be available to builders on cheaper rates. This will prevent over exploitation of quarries and save our environment.The Ironmaking Process | New Zealand Steel,This product, which is known as primary concentrate or PC, is pumped in a slurry to the steel mill where it is dewatered and stockpiled. At the mill, to prepare the materials for chemical reduction, coal and primary concentrate (ironsand), along with a small amount of limestone (CaCO 3 ), are mixed together before being fed into the top of each of the four multi-hearth furnaces.Foundry Sand Types - Gray Iron, Ductile Iron, Steel,,According to the different binders, foundry sand used for moulding can be divided into green sand, water glass sand and resin sand. Green Sand (Clay Sand) Clay sand is the mixture of natural silica sand, clay, additives and water. The clay used to make wet clay sand is bentonite clay. The compressive strength is generally 0.05 to 0.1 Mpa.
