There is a trend of high efficiency and utilization of natural resources to reduce the resource wasting as well as lower the environmental stress. So it is the same with the steel industry, which adopts a method of enlarging the research and craft of energy-saving and environmental technology.
Chinahas gained a fast progress on the technology of steel slag recycling and utilization. The main content of steel slag is Ca, Fe, Si, Mg, Al, Mn, P, etc oxidizing material. And the main purpose of steel slag is natural recycling in steel company as solvent instead of lime, also can be as raw material for steeling in blast furnace or welding furnace as well as the cement raw material for building road base and railway base and improving soil conditions.
Also as the raw material for metallurgy as firing solvent, cupola furnace solvent, returning slag for steelmaking, even recycling the waste steel using the magnetic selective technology.
Steel slag can also be used for building material: owning to the slag has the similar tri -calcium silicate, dicalcium silicate, and iron & aluminum acid salt, etc activity mineral ore which is of water hard gelatinization with cement, which can be used as raw material and admixture for producing cement with no clinker or less clinker. What’s more, the steel slag has the characteristic of high density, high strength, coarse of surface, stability, wear resistance and fastness combined with asphalt so it is also widely used in railway, highroad construction and backfill engineering, especially in the moor, bench of road building.
Application in agricultural for steel slag phosphate fertilizer for its content of zinc, manganese, iron and copper, which can have a better effect on different soil and plant that lack of microelement. Steel slag as silicon fertilizer can change the acid soil.
Because of its high hardness, steel slag is hard to grind. It’s very important to choose a high performance machine and vertical mill is the best choice. Vertical mill is manufactured by Liming Heavy Industry focusing on solving the low output of grinding mill with high energy consumption, based on absorbing the European advanced technology and combining our company’s designing concept and technological demand of many years’ experience. After its promotion with many years’ patient design and improving, the large-sized grinding mill equipment can totally meet customer’s requirement, what’s more, vertical mill has a long life-span with little consumption of metal as well as low running cost, which is favored and popular among steel industry and company
