More Information
Summary:The invention relates to the technical field of preparation of water-permeable materials, in particular to a sintering process of a steel slag water-permeable material, which comprises the following steps: crushing, grading and screening steel slag, weighing 300g of steel slag fine powder, 190g of kaolin, 10g of magnesium oxide, 10g of aluminum oxide and 6ml of hydrogen peroxide, pouring into a ball milling tank, carrying out ball milling for 30 minutes, uniformly mixing, pouring into a prefabricated mold, standing for 3-5 minutes, and carrying out foaming molding; the mold is put into an electric heating constant-temperature blast drying box to be dried for 10-12 h, the mold is taken out, fettled and put into a resistance furnace, the sintering temperature is 1200 DEG C, the heat preservation time is 75 min, the heating rate is 3 DEG C/min, and the water permeable brick is prepared. The water permeable brick prepared by the invention has better performance. The permeable coefficient is 2.69 * 10 <-2 > cm/s,
