Read MoreManaging Heat Loss In Iron Furnaces & Ladles
Managing Heat Loss Heat loss is a significant concern in many foundries as it costs money to heat iron to the required temperature. Therefore, it is essential to take measures to keep the iron at the desired temperature for as long as possible. One way to achieve this is by selecting the appropriate type of…
Read MoreTips For Better Mag Recovery in Ductile Iron
Improving MgFeSi Recovery in Ductile Iron While using MgFeSi to produce ductile iron can be very cost-effective compared to alternative treatment methods, it can sometimes get out of hand with high usage rates. Several benefits can be realized when improving the recovery of magnesium in producing ductile iron and lowering those addition rates. The addition…
