Development of Ferro-Nickel Smelting From Laterite in Japan
[12-21-2007]
    In Japan, all smelting plants have been making efforts to reduce their costs by converting from oil to coal, and also by utilizing the heat of the gas exhaust from the rotary kiln and electric furnace as well as the heat of the slag, while continually strivin......

Freeze-thaw resistance of concrete incorporating ferronickel slag fine aggregats
[12-21-2007]
A total of five ferro-nickel slag fine aggregates were examined by blending natural fine aggregates to investigate the freeze-thaw resistance of concrete with these fine aggregates. The volume blending ratio of slag fine aggregates in excess of 60% resulted in poor freeze-thaw re......

Development of Ferro Nickel Smelting at Hyuga Smelter
[12-21-2007]
The development of new processes for conserving energy in rotary kiln furnace production of ferronickel is discussed. Measures carried out to meet the need for reduction in energy consumption included: substitution of pulverized coal for heavy oil in the rotary dryer and the ro......

An economic route to ferro-nickel
[12-21-2007]
In the conventional process to produce ferronickel, the drying and calcining of ore is followed by smelting in either three- or six-electrode AC arc furnaces. DC arc furnace technology has been shown to have advantages over traditional AC techniques in several applications, mai......
