摘要

The production process of glass wool and rock from the recycling of steel slag and / or resu00ecduo cutting of granite. The present invention relates to the manufacturing process of rock wool and glass wool as raw material, using a partial residue generated in the cutting of granite and the slag of electric furnace.The glass wool and rock are widely employed as insulating material thermo acoustic and raw materials used in the production of these are derived from non renewable natural resources.The present invention proposes the replacement of part of the raw material by two industrial waste slag electric furnace: from the steel industry and the residue of cut granite, from the mining industry of ornamental rocks.This substitution allows a reduction of the extraction of mineral resources, a profitable destination for these residues and an economy in the production of wool.
