Abstract [en]

Industrial tests on recycling of iron-bearing sludges through BOF converter in the form of cold bonded pellets were carried out at the S SAB Tunnplat. The total amount of about 400 tons of cold bond pellets was produced in a pilot scale pelletizing plant on the basis of the results of experimental studies concerning cold strength and reduction behaviour. The charging weight of cold bonded pellets in the BOF converter with 114 tons varied from 0,5 to 2,5 tons. The effect of charging cold bonded pellets on the amount of sludge and the composition of slag generated in the BOF converters was studied. The slopping problem occurred in the industrial tests is discussed. According to the results of industrial tests, in general the converter process was not subject to any adverse disturbances due to the addition of cold bonded pellets. Dust, sludge, recycling, cold bonded pellets, pilot scale tests and industrial tests.
