Iron ore sinter is still the main domination part of the iron burden in most blast furnaces. Thus, the sinter production costs are quite important for the iron production. Even more important is that the sinter quality significantly affects the blast furnace process and its consumption of reducing agents. A high and homogeneous sinter quality is needed since it leads to less variations in the blast furnace process.
Recently, new challenges raise in sinter plant operation. Due to a sharp raise of the costs of fuels and CO2-certificates it becomes more and more necessary to work with alternative fuels. Furthermore, due to the raising world wide demand for high quality ores the ore supply became difficult resulting in decreasing and varying quality of ores available for sinter plants.
A strong discrepancy appears between decreasing fuel and ore quality, raising demands to sinter quality and to environment protection. Thus, it is of essential importance to develop new techniques and new measurement and control devices able to fulfil the new demands.
Overall aim of this RFCS project is is a breakthrough in sinter control and a clear improvement of fuel utilisation. To achieve that aim innovative approaches are necessary covering all main sinter process steps: From control of blending, melting, charging and fuel dosing to total control of the sinter process.
In the project all theses approaches are combined to reach one common goal: to perfectly adapt to new fuels and ores or simply “Total Sinter Control”. The benefits will be to decrease emissions and costs while keeping high and constant sinter quality.
