COATED ROTATING WHEEL FOR MINERAL MELT FIBERIZATION AND METHOD FOR COATING OF A ROTATING WHEEL FOR MINERAL MELT FIBERIZATION

摘要

Mineral melt fiberization rotating wheel coating and process for its application solves above technical problem of increased wear and tear by applying protective coating to lateral surface of mineral melt fiberization rotating wheel, and further, by applying said coating using thermal spray of metal and ceramic materials. During rapid rotation of the rotating wheel of the centrifuge within the mineral melt fiberization apparatus the melt, preferably with high aluminosilicate contents, flows onto the outer-lateral surface of the rotating wheel, and this melt disengages from said outerlateral surface under influence of centrifugal forces, and transforms into a fiber through well known process in state of the art. If higher efficiency is desired, cascade is used, this cascade increases wear and tear on the outer-lateral surface of the rotating wheel.
