Common slag treatment process in Japan is shown in Figure 4.4.12 [81]. About 80% [79] of BF slag is quenched by water spray and the quenched BF slag sand produced is used mainly for cement, concrete and civil engineering resources. The rest is cooled by field air cooling and the slow cooled slag is used as a resource for road construction

Blast furnace slags cooled in air constitute a crystallized material used as raw material instead of sand in the production of concrete. In the case of water applied during granulated slag production, it is possible to recover heat from the slag quenching water, thereby reducing energy consumption. Blast furnace slag is obtained at 1300–1400°C; viscosity is around 0.4–1.0 poise; the

Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus).

life cycle analysis of a process. The manufacturing process (Figure 2) begins with the formation of a single-use mold from sand and binders, which hold the sand mold together. A lot of the sand comes from the sand reclamation process, where sand from previous molds gets reclaimed for use in new molds. Cores are also made at this point for parts

Modern casting production methods can manufacture thin and accurate molds—of a material superficially resembling papier-mâché, such as is used in egg cartons, but that is refractory in nature—that are then supported by some means, such as dry sand surrounded by a box, during the casting process. Due to the higher accuracy it is possible to make thinner and hence lighter castings, because
