Olivine is used as a slag conditioner which minimize the attack on refractory material
by aggressive slag . olivine’s high forsterite content makes Fast achievement of the optimum degree of
saturation, improved formation of foamed slag and energy is balance when used in electric arc furnaces and
ladle.
