<p>PROBLEM TO BE SOLVED: To provide a high-strength inorganic fiber made from incinerated ash as a main raw material, and a method for producing the inorganic fiber. SOLUTION: This method for producing the inorganic fiber is characterized by comprising a step of mixing the refuse incinerated ash with a thermite exothermic reactant, a step of melting the resultant mixture with an oxidation flame and converting the mixture into a slag, a step of making the slag flow into a well, a step of making the slag flowing into the well stay in the well, settling and separating a molten metal in the slag, a step of overflowing the molten slag from a weir of the well and pouring the molten slag into a holding furnace, a step of regulating components of the slag in the holding furnace and a step of making the molten slag flow down from the holding furnace and forming the molten slag into a fiber.</p> |
