Heat recovery can often go hand-in-hand with pollution control. An installation in Norway is described, where heat removed upstream of bag filters on a ferro-silicon plant is used to raise steam for electricity generation.detailed
The effects of the introduction of iron or ferro-silicon particles on the graphitization of carbon mixes at relatively low temperatures are described. It is shown (i) that both iron and ferro-silicon materially accelerate the rate of graphitization and that ferrosilicon is more effective than ir...detailed
Novel tempered resin bonded ferro-silicon nitride-corundum refractories containing 0 wt%, 15 wt% and 25 wt% ferro-silicon nitride were prepared respectively. Creep tests were performed under a load of 0.2 MPa at a temperature of 1300 °C for 50 h in air. The results showed that creep performance...detailed
