The techniques to reduce the wear rate caused by these tribological systems can be briefly summarized as separating the contacting surfaces with a lubricant film, choosing material combinations that are resistant to sliding interaction, hardening the wearing surface, improving the resistance to fracture of a wearing surface, improving the corrosion resistance of an eroding surface, and ...

12.5 Iron And Steel Production Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron …

Iron ore extraction techniques - ScienceDirect

01-01-2015· Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as "dogger") allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...
