Resource utilization field.
Background technique
Because world steel yield is huge, silicomangan and dilval are as steel deoxidation and alloying component, every year
Yield be also huge, while bringing a large amount of discharges of silicomanganese and nickel-iron smelting waste residue.Currently, silicomanganese and nickel-iron smelting are useless
The processing mode of slag is mainly stored up and two kinds of resource utilization.Stockpiling causes the waste in soil and latency environment dangerous, resource
Change and utilizes mainly in terms of cement is with paving the way.Mineral wool is widely applied as a kind of heat preservation and heat-insulated, acoustic material
In each field of national economy.It is newest studies have shown that mineral wool can be made by quenched equal process means in metallurgical slag, and
It is finally made various mineral wool products.Meanwhile mineral wool is made in metallurgical slag, not only solves the stockpiling of metallurgical slag
And pollution problem, it is a kind of metallurgical slag that compared to the resource utilizations approach such as cement, mineral wool product, which has more economic value,
High value added utilization new way.
