Usually two thermocouples were used in the trials.The speeds of the sinter machine were maintained in the range of 130-140 cmmin during the first set trials and 120130 cmmin for the second set.In both sets of the trials the sinter samples and plant operation conditions corresponding to the temperature profiles were collected.
For use in the blast furnace.Careful monitoring of temperature within the sinter plant is important blast furnace blast furnace is the heart of integrated steel plant.Thermocouples used in blast furnace faces the most challenging temperature.
Many thermocouples, embedded above, under and in the sinter mix.The 0-1 mm fines from the mine were dumped.Only the richer 1-8 mm fraction was used to produce sinter.In 2007, eramet comilog decided to study the possibility to recover part of the 0-1 mm fraction and use it in the sinter plant.
An integrated visual monitoring and guide system has been in operation in this plant since 1995, and consists of fifty thermocouples, 5 on-bed flow meters, a thermal imaging device and a sub-gate opening control system 3.The thermocouples are situated below wind boxes 15 to 25, and the 5 flow meters are on the bed of box 6.
Sinter is the most common blast furnace burden material used in integrated steelworks throughout the world with the exception of scandinavia and north america where the ore types and their local availability make the use of pellets as a burden, more attractive.
An improved experimental technique has been developed to measure, concurrently, the oxygen partial pressures and temperatures within a pilot scale iron ore sinter pot as a function of time.The measurements and thermodynamic calculations have demonstrated that the oxygen partial pressure at peak bed temperature and during cooling can be oxidising or reducing relative to hematite.
