Abstract |
AB |
[EN] A grating for a blast reheater consists of a cast iron material which exhibits linear expansion properties and no significant structure changes in the 20-600 degrees C range. The iron has a strength (DIN 1691) of more than 240 MPa at 600 degrees C and exhibits toughness with a strain rate of more than 10%. The cast iron may have (i) a bainite-free structure with vermicular graphite; or (ii) a pearlitic-ledeburitic structure with lamellar graphite and containing 0.6-1.0 wt.% Cr, 0.8-1.5 wt.% Ni and 0.4-0.7 wt.% Mo, the total content of Cr, Ni and Mo being 1.8-3.2 wt.%. |
