Technical Field
The invention relates to the field of metallurgy, in particular to the field of roasting of iron concentrate pellets.
Background
In recent years, the iron and steel industry in China continues to grow at a high speed, and the demand for iron ores is increasing. With the progress of blast furnace ironmaking technology, the 'concentrate' work is highly valued. Pellets, which are one of the main components of the blast furnace burden structure, are produced in an increased development state at present in China, but the proportion of the pellets to raw materials required by the yield of pig iron is still very low, and more importantly, the performance of finished pellets directly influences the blast furnace smelting and the whole steel production.
At present, the main method for producing pellets in China adopts a belt roasting machine, and has high requirement on the stability of raw materials in the production process. This is because the whole process of firing (drying, preheating, firing, cooling) is performed on the same equipment, and it is impossible to change the residence time of pellets in each stage by adjusting the machine speed. Such frequent switching is impractical in actual production unless the upper hood section and bellows configuration are changed. Therefore, the construction of the belt roasting machine is generally suitable for large mining companies and steel plants with relatively stable raw material supply for a long time, and has certain limitation, which is a technical problem brought by using the belt roasting machine in the steel smelting industry.
