The present invention relates to a process for manufacturing a cast basalt product, and a system for manufacturing the same. The process for manufacturing a cast basalt product, of the present invention, comprises: (S10) a material treatment step of collecting and mixing, in a predetermined mixing ratio, a material comprising ferronickel slag, steelmaking slag, and bottom ash; (S20) a melting step of obtaining a molten product, which is in a completely molten state, by charging the mixed material into a melting furnace and increasing the temperature to 1450-1500°C, and discharging the same at a temperature of 1100-1250°C through a turndish; (S30) a casting step of taking out a tile- or tube-shaped molded product by injecting the molten product into a tile casting machine having a mold thickness of 10-15 mm, preheating the same at 200-400°C, and then compressing the injected molten product, or by injecting the molten product into a centrifugal casting machine, which has a mold thickness of 9-30 mm and which is rotating at a predetermined rate, preheating the same at 350-500°C, and then rotating the injected molten product; and (S40) a heat treatment step of charging the molded product into a bogie, which is preheated at 700-750° in a bogie preheating section of a heat treatment furnace, heat treating the molded product by increasing the temperature to 710-910°C in a heat treatment section, naturally cooling the same at room temperature for 16-24 hours by moving the same to a cooling section, and then discharging a final basalt product at 50°C or below, and thus there is an advantage of effectively manufacturing a high-quality basalt product by using, as a raw material, a by-product of steelmaking and thermal power generation. |
