Embodiment 1

[0022] The waste skateboard powder raw material is ball milled and ferromanganese is recovered by using a permanent magnet roller type strong magnetic separator combined with a pulsating high gradient magnetic separator. In the biofilter with stirring device, add 1 t of waste skateboard powder that has been treated with strong magnetic field and 10 m 3 Silica Bacillus Solution. It was carried out for 5 days and nights at 22°C without disinfection, the solid-liquid ratio was 1:5, the leaching time was 5 days and nights, and the corresponding biological culture solution was added. Chemical composition of final waste skateboard powder Al 2 o 3 increased to 93.4%, SiO 2 The content is reduced to 9.51%, and the aluminum-silicon ratio reaches 8.0. Then in the biofilter with stirring device, add desiliconized waste skateboard powder and 800 dm 3 Concentrated Aspergillus solution. Under non-sterile conditions at 22°C, add water for 10 m 3 , cold soaked for 10 days and nights, a...

Embodiment 2

[0025] The waste skateboard powder raw material is ball milled and ferromanganese is recovered by using a permanent magnet roller type strong magnetic separator combined with a pulsating high gradient magnetic separator. In the biofilter with stirring device, add 1 t of waste skateboard powder that has been treated with strong magnetic field and 10 m 3 Silica Bacillus Solution. It was carried out for 5 days and nights under non-sterile conditions at 22° C., the solid-liquid ratio was 1:5, and the leaching time was 5 days and nights. The difference between Example 2 and Example 1 is that no biological culture solution is added. Chemical composition of final waste skateboard powder Al 2 o 3 increased to 80.0%, SiO 2 The content is reduced to 14%, and the aluminum-silicon ratio reaches 7.09.

[0026] The formula and production of aspergillus for removing iron and recycling the waste skateboard powder are the same as in Example 1. The final product has an apparent porosity of...

Embodiment 3

[0028] The combination of permanent magnet roller type strong magnetism and pulsating high-gradient strong magnetism to remove iron from waste skateboard powder, and the formula and production of silicate bacteria to desilicate and recycle waste skateboard powder are the same as in Example 1. The difference from Example 1 is that when Aspergillus removes iron from the waste skateboard powder, add 20 m of water 3 , cold soaked for 13 days and nights, and then washed the ore samples with tap water until neutral, and dried. The results of chemical analysis before and after leaching showed that Fe 2 o 3 The highest reduction rate was 44.8%, and the lowest was 16.0%.

[0029] The product has an apparent porosity of 10%, a normal temperature compressive strength of 130 MPa, and a high temperature flexural strength of 15 MPa. Its performance indicators such as oxidation resistance, erosion resistance and thermal shock resistance are all excellent or good.

Abstract

The invention relates to a recycling method of a refractory material of a sliding plate of a sliding water gap for waste steelmaking, in particular to a method for treating waste sliding plates to recycle by a biological method and waste sliding plate powder obtained by the method. The method for treating the waste sliding plates to recycle by the biological method comprises the following steps of: (1) carrying out treatment of removing manganese and iron on the waste sliding plate powder; (2) carrying out silicon removal on the waste sliding plate powder by bacillus silicate; (3) carrying out iron removal on the waste sliding plate powder by aspergillus; and (4) washing to be neutral and drying. In the project, due to adoption of biotechnology for removing silicon, manganese and iron, the energy-saving and emission-reducing purposes can be effectively achieved, and simultaneously the pollution of nonbiodegradable aluminium-carbon sliding plates to the environment is eliminated, so that the method is beneficial to environmental protection.

Description

Technical field [0001] The present invention involves a method of recycling the refractory material for abandoned steelmaking skateboarding materials, especially the method of recycling the abandoned skateboarding of the biometric process and the method of recycling and reuse of this method. Background technique [0002] my country's steel output has currently reached about 500 million tons per year, of which a large amount of skateboarding is used on the steel bag and linked middle bag during the production process.After the skateboard is used multiple times, it is abandoned due to the expansion of the aperture and the sliding surface damage, which is treated as solid waste.This processing method not only wastes resources, but also severely pollutes the environment because aluminum carbon skateboarding is difficult to eliminate naturally.Therefore, the research on the use of skateboarding re -use technology can not only reduce costs, but also has far -reaching significance in th...
