The invention discloses a non-sintering type steel slag microporous filter ball and a preparation method and application thereof. The non-sintering type steel slag microporous filter ball is mainly made of the following raw materials by weight: steel slag: 50-60%; Cement: 25-35%; Gypsum dihydrate: 4-6%; Sodium silicate: 10-20%. The invention uses steel slag to replace the natural traditional raw materials to prepare filter balls, turns wastes into treasures for resource utilization, and adopts a non-burning process that does not require high temperature calcination and has low energy consumption, and the prepared steel slag microporous filter balls replace cobblestones It can be used in the fields of blast furnace bottom filtration and slag flushing process, pavement laying, gardening and construction, etc., which can reduce costs, improve the utilization rate of waste, effectively reduce the consumption of natural resources, and prevent damage to the ecological environment. The non-burning type steel slag microporous filter ball of the invention has good performance, and at the same time, the non-burning process has low production energy consumption, and conforms to the national environmental protection policy of energy conservation, emission reduction and green development. |
