Two ductile iron grades of GJS-500-7 and GJS-500-14 were cast with silicon content of 2.36% and 3.71%, respectively. The cast geometry consisted of six plates with different thicknesses that provided different cooling rates during the solidification. Microstructure analysis, tensile and hardness tests were performed on the as-cast material.

Desulphurization of Liquid Steel. Solubility of sulphur (S) in liquid iron (Fe) is quite high. But the solubility of S in solid iron is limited. It is 0.002 % in ferrite at room temperature and 0.013 % in austenite at around 1000 deg C. Hence, when liquid steel cools down, sulphur is liberated from the solution in the form of iron sulphide (FeS

Jan 01, 2003· The other way for size reduction of steel slag is one-stage dry autogenous grinding. One advantage is that one autogenous grinding machine can replace several crushers in multi-crushing so that its operation is simple. Moreover, the metallic iron product discharged from the grinding machine contains Fe as high as 80%. Cited by: 525
