Iron fine powder waste slag water permeable brick production method

Abstract

The invention provides an iron fine powder waste slag water permeable brick production method. According to the iron fine powder waste slag water permeable brick production method, the raw material form of the traditional firing brick is broken through, wherein iron fine powder waste slag and loess mud are matched according to a reasonable ratio to form a brick production material, and firing is performed by using a suitable firing process to finally achieve the firing brick, wherein the dense holes can be formed and are regularly and orderedly arranged after the iron fine powder waste slag and the loess mud are fried so as to provide a directional water permeation effect, wherein the rapid water permeation in the vertical direction can be performed, and the water does not easily permeate toward the side surface; a lot of iron fine powder waste slag can be consumed, such that the waste slag accumulation problem is effectively solved, the waste is utilized, the environmental pollution is reduced, the consumption is high, and the waste utilization and the waste slag accumulation problem solving effect are obvious; and compared to the method in the prior art, the method of the present invention has advantages of rapid directional water permeation effect of the product, effective solving of the waste slag accumulation problem, waste utilization, environmental pollution reducing, green environmental protection, low cost, and strong practicality.

Description

technical field [0001] The invention relates to the field of brick making, in particular to a method for producing iron fine powder waste slag permeable bricks. Background technique [0002] The brick-making process is well-known, such as the Chinese invention patent CN201610131770.9 discloses a process for producing clear water bricks and paving bricks with coal gangue, 1) sending the mixture of coal gangue and shale into a ball mill, and the crushed particle size is 100- 120 mesh; 2) The pulverized material is fully mixed with water for 7-10 minutes in a planetary wheel mill mixer; 3) The moisture content of the mixed material is controlled to be 7-8%, and it is pressed on a 630-ton hydraulic brick press for 3 First, ensure sufficient exhaust, so that the extruded bricks will not crack, and the bulk density will reach more than 2.0, and finally molded; 4) Dry the molded product in the room for 1 day, and then enter the drying kiln to burn the finished product once; 5) Comb...
