[0004] However, in recent years, with the rapid expansion of the use of basalt, silica, and coke, resource shortages have resulted, and raw material prices have risen sharply
In addition, the production of cold bulk slag raw materials is also decreasing day by day, coupled with factors such as the impact of cupola on the environment and incomplete homogenization of slag system resulting in unstable quality of slag wool, the development of cold state production of slag wool technology is limited
The main difficulty in producing slag wool from hot blast furnace slag is in the mixing and homogenization technology of cold solid conditioner and hot melt liquid blast furnace slag, that is, at high temperature, the addition method of quenching and tempering material, the melting of solid and the The mixing of slag liquid makes it difficult to achieve homogeneity and uniform temperature of the slag system

Embodiment Construction
[0024] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. Detailed instructions:
[0025] as attached figure 1 Shown, the present invention is a kind of slag wool processing method, and the step of described slag wool processing method is:
[0026] 1) Raw materials for processing slag wool include liquid blast furnace slag, sandstone, and sodium carbonate. Liquid blast furnace slag is used as raw material, sandstone is used as a tempering material, and sodium carbonate is used as a viscosity improver. When processing slag wool, liquid blast furnace slag is added to the molten conditioning material In the tempering furnace 4, sandstone and sodium carbonate are blown into the melting and tempering fur...

Abstract
The invention provides amineral wool processing method applied to the mineral wool production field. The said processing steps of mineral wool comprises 1)adding liquid blast furnace slag ,which is used as a raw material, into a melting quenching and tempering furnace (4),andblowing sandstone ,which is used as a modified material, and sodium carbonate ,which is used as an viscosity improving agent, into the melting quenching and tempering furnace (4); 2) after melting and mixing the liquid blast furnace slag, sandstone and sodium carbonate at a high temperature , conveying the high-temperature melt to an intermediate reservoir (8) through a flow mixing arrangement (7); 3) after the liquid high-temperature melt (6) in the intermediate reservoir (8) flows out from a slag outlet of the intermediate reservoir (8), performing silk throwing with a centrifugal silk throwing machine (9) to form mineral wool. The processing method for mineral wool disclosed by this invention can remarkably reduce the energy consumption during the mineral wool processing and effectively utilize the potential heat energy of the high temperature slag to reduce the energy waste, therefore minimizing the processing cost of mineral wool.
Description
technical field [0001] The invention belongs to the field of slag wool production, and more specifically relates to a slag wool processing method. Background technique [0002] Slag wool is made of blast furnace slag as the main raw material, adding part of the conditioning agent, and is made of filamentary inorganic fiber by high-speed centrifugation or blowing after melting. It has the characteristics of small thermal conductivity, non-combustible, harmless to human body, long service life, good sound insulation effect, light weight, wide temperature range, mothproof, cheap, corrosion resistance, good chemical stability, good sound absorption performance, etc. , can be used for filling insulation, sound absorption, sound insulation of buildings and filling insulation of various thermal equipment. [0003] At present, in China, cold blast furnace slag and basalt are generally used as main raw materials, a certain proportion of silica, dolomite, etc. are used as tempering m...
