Abstract

The invention provides a process method for producing mineral wool from blast furnace slag, and belongs to the technical field of mineral wool production.The process comprises the steps that a composite ingredient, a cosolvent and the blast furnace slag in a certain proportion serve as raw materials and are fed into an electric furnace to be smelted in the electric furnace, melted and tempered, the flow is controlled through a furnace opening, and the raw materials are conveyed to a centrifugal machine to be made into high-end mineral wool. Compared with a traditional cupola furnace production process, the novel mineral wool production process provided by the invention has the advantages that coke melting is not needed, noxious substance emission is avoided, the material melting speed is higher, the production efficiency is higher and the like, and the process comprehensively considers multiple aspects such as atmospheric pollution environment-friendly treatment, equipment operation cost reduction, auxiliary material consumption and the like; wide application prospects are realized.

Description

technical field [0001] The invention belongs to the technical field of mineral wool production, and in particular relates to a process for producing mineral wool from blast furnace slag. Background technique [0002] Mineral wool (or rock wool) is a man-made inorganic fiber, which has excellent properties such as light weight, low thermal conductivity, strong heat resistance and non-combustibility. This is a commonly used insulation material, such as vermiculite, perlite, diatomaceous earth, foam cement, etc. It is difficult to compare with it comprehensively. Adding a special binder to mineral (rock) wool can make various flexible or semi-rigid products, such as mineral wool shell, mineral wool board, mineral wool felt, etc. These products can be widely used in petroleum, electric power, Metallurgy, chemical industry, construction, transportation and other industries can also be used as sound-absorbing and sound-insulating materials. In the existing production process of ...
