Description: Ferro-alloy brquettes are produced fro use in cupola melted gray and ductile iron base metal,and are available in a variety of chemcial compositions and sizes.They may also be tailored to fit specific individual requirements. All products are produced from fresh 50% and 75% ferro silicon fines generated through lump crushing operations.No sand or other aggregate fillers are used.The silicon content is controlled through varying the ratio of 50% and 75% ferro silicon fines used in each batch mix.The silicon recoveries from these products are very similar to that of lump ferro silicon. Chemical Composition: 1.Si 65-72%,Al 1.5%max,Ca 1.5%max,Mn 0.5%max,P 0.04%max,S 0.12%max,C 1.5-5%, 2.Si 50-60%,Al 1.5%max,Ca 1.5%max,Mn 0.5%max,P 0.04%max,S 0.12%max,C 1.5-8% Sizing:3.5-6cm Uses: It could be used in any cupola melting operation where high levels of silicon recovery are desired. Briquettes products may be used as direct replacements for ferro silicon bricks,lump ferro silicon, and silicon carbide.For applications where a carbon contribution to the melt is desired,carbon additions may be made to the product formulation. Remarks:In addtion to the above products,various specifications and size could be produced to meeet specific individual requirements according to different customers.
