Redux EF40 is a fluorspar-free flux that keeps furnaces and ladles free of slag build-up and actually extends refractory life. Some foundries using EF40 have doubled, and even quadrupled, refractory life! Using EF40 results in significant cost savings by maintaining furnace volume, increasing melting rates, and reducing electrical loads. Available as a briquette, brick, or powder.
