Sponge Iron - an overview ScienceDirect Topics

The development of this process has led today to produce high-quality iron powder by grinding and then ball milling of the sponge iron into fine particles and followed by heating the as-milled iron powders in hydrogen to remove the oxides. Modern P/M technology has started in the 2nd decade of the last century with a glorious achievement at that time, when a mass production of qualified ...

This accumulation of sintered solid particles which form rings along the length of the kiln hinders material flow, lowers productivity and life span of the kiln. To maintain the quality of sponge iron and improve on performance of rotary kilns, there is need to minimize accretion build up in the kiln.

for sintered iron and steel parts. From Table 2.1 , it can be seen that in 1965 iron powders were used almost exclusively for low- and medium-density applications, i.e. for parts having pressed densities from 5.5 to 7.0g/cm 3. First after about 1970, increasing quantities of iron powders were used for high-density applications, i.e. for parts having pressed densities higher than 7.0g/cm 3 ...

Iron Sponge Process Oil and Gas Separator

The use of an adequately designed gas scrubber or filter separator upstream of the iron sponge unit will minimize the amount of liquids that condense on the bed. Sometimes the process can be arranged so that the scrubber operates at a lower temperature or higher pressure than the iron sponge unit, so that there is no possibility of hydrocarbon liquids condensing in the iron sponge unit.
