Cast Iron: Properties, Processing and Applications - Matmatch

Production and processing . To produce cast iron, the iron must be extracted from iron ore. The ore is smelted in a blast furnace where it separates into pig iron and slag. The furnace is heated to around 1800 degrees Celsius in an oxygen atmosphere and the slag formed rises to the top and can be removed. On April 1-5, 2019, the Sixth International Slag Valorisation Symposium took place in Mechelen, Belgium. This Symposium aims at contributing towards near zero-waste processing and closing material loops in the metallurgical sector through creating applications for slags, which are produced as residues of high temperature metallurgical processes.

Steelmaking Slag - an overview | ScienceDirect Topics

Apr 04, 2012· 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, concrete coarse aggregate, and so on. During the smelting process a homogenous slag cover is produced which due to their low density swims on the molten metal bath as slag blanket. The slag is separated from the metal in the melt flow and then casted for cooling. Afterwards the slag is crushed and screened in the slag processing plant regarding to the following application.
