ABSTRACT:
For the purpose of utilizing as a sinter raw material a rolling mill sludge with a grease deposit having a high moisture content, which is deposited in a waste water pit of a steel rolling mill, the moisture content of said rolling mill sludge is reduced to from about 1% to 10% by drying said rolling mill sludge at a temperature of from about 120.degree. C to about 200.degree. C, preferably of about 140.degree. C to about 150.degree. C, with the use of the waste heat of a sinter cooler of a sintering machine, or by mixing said rolling mill sludge with a mill scale of a low moisture content collected without the use of roll cooling water; and then, said rolling mill sludge, the moisture content of which has thus been reduced, is continuously fed, by cutting into substantially equal batches, to at least one of a sinter discharge section, an entry section of said sinter cooler, belt-conveyor for fines return provided adjacent to a hot screen, and a return hopper of said sintering machine; whereby said grease deposit is substantially completely removed through combustion or evaporation with the use of the heat of the sinter produced by said sintering machine.
