Optimum and powerful grain refinement is a huge asset in advancing melt quality. Optifine grain refiner in conjunction with Opticast technology is achieving exceptional results in the routine production of a number of demanding high quality alloys in casthouses worldwide. MQP, under an exclusive manufacturing agreement with AMG, supplies an exceptionally powerful TiBAl grain refining rod known as Optifine. Optifine is a highly effective grain refiner and can achieve the level of refinement needed to avoid ingot cracking at up to 80% lower addition rates than standard TiBAl grain refiners. This results in improved quality and reduced operating costs over a wide range of aluminium alloy compositions. Optifine is now in routine usage in major casthouses worldwide in the production of over three million tonnes of aluminium alloys with outstanding results.
