Abstract
Prod. for desulphurising molten cast iron, consisting of granules of calcium carbide composed of calcium carbide powder coated or agglomerated with a binder consisting either of an organic material having a m.pt. of 70-100 deg. C or a polymerisable resin with a polymerisation temp. of 40-70 deg. C. The Ca2C pref. comprises grains coated with a first layer of a binder which is solid at ambient temps., and opt. coated with a more or less continuous external layer of Ca2C grains of finer particle size than the coated particles. The binder is e.g. a rosin, stearic acid, a satd. fatty ester of glycerol with a purity of at least 90%, esp. hydrogenated castor oil based on glycerol trihydroxystearate, furfurylic resins, polyesters, vinyl-ester resins or epoxy resins. Pref. the amt. of binder used is 0.2-10 wt.% w.r.t. the wt. of Ca2C.
