Recovery and utilization of oxides in steel slag of LF refining furnace

LF refining furnace slag contains CaO, Al2O3, SiO2 and other oxides, there are very few LF refining furnace slag as a raw material for production, are used in glass and fuel industries.There have many kinds of refractory products in our factory.Such as china fire brick, refractory raw mateials .Welcome to know our factory more.LF refining furnace slag is rich in Al2O3 is also used as raw material for the extraction of alumina, LF refining furnace slag generally w (Al2O3) of 20% to 40%, and low-grade bauxite quite.?

The aluminum in the LF refining steel slag is present in the form of a 12CaO ? 7Al2O3 mineral phase with high activity. It is easier to react with the acid and alkali, and it is easier to extract the alumina compared with the traditional aluminum-containing minerals. The study of using industrial waste acid acidification LF refining furnace slag to obtain aluminum containing Al3 + solution preparation of aluminum chemical products, and then extract alumina, raw material costs and operating costs lower than similar levels, with good economic benefits. The above traditional application methods of low added value, the use of small, and can not really play LF refining furnace slag as the value of production resources. LF refining furnace slag and metallurgical production of the main components of the raw materials used in similar components, the LF refining furnace slag in the metallurgical production of resources in the re-use, can greatly improve the utilization of LF refining furnace slag, saving metallurgical raw materials. Therefore, LF refining furnace slag in the field of metallurgical recycling is the most cost-effective way.Do you need any refractory products? There have many kinds of refractory products on our factory ,such as fire brick for sale, clay insulating bricks, refractory nozzle,refractory raw materials. If you need any refractory products like clay insulating bricks, welcome to contact us anytime.
