Abstract

The invention discloses a high-performance synthetic slag block material.The high-performance synthetic slag block material is prepared from, by mass, cement 8%-15%, granulated blast furnace slag 45%-60%, quartz sand 6%-15%, pulverized fuel ash 6%-15% and waste rock wool 10%-15%.Because output of steel slag (dried slag) of steelworks has banned in our country, slag wool production needs the granulated blast furnace slag (water slag), the slag wool production costs are increased, and a process becomes complicated.The high-performance synthetic slag block material can be produced by using the granulated blast furnace slag, and the slag wool production process can be simple.The excellent effects of waste utilization and environmental protection are successively achieved, and the high-performance synthetic slag block material has the advantages of being controllable in refractoriness, chemical component proportion, product block diameter and product density and the like.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a high-performance synthetic slag block and a preparation method thereof. Background technique [0002] Blast furnace slag is a kind of water slag discharged from the blast furnace when smelting pig iron. When smelting pig iron, the raw materials of the blast furnace are added, in addition to iron ore and fuel (coke), there is also a flux. When the furnace temperature reaches 1400°C to 1600°C, the flux reacts with the iron ore to generate pig iron and slag. Blast furnace slag is a fusible mixture of gangue, ash, flux and other impurities that cannot enter pig iron. Slag is one of the important components of "three wastes" in industrial production. It is produced from mining, washing, smelting, purification, processing, and use, and a considerable part of it is silicate. Most of the industrial silicate slag lacks biological activity, and some are biologically toxic, occupying t...
