In the blast furnace production process, the high iron content in the sludge produced by collecting, Iron can be used as recycled raw materials. Experimental study found that the use of magnetic roasting - weak magnetic iron powder method of recovering technology is feasible. The optimum conditions are: the grinding fineness is 87%, calcination temperature is 750 °C, roasting time is 25min, magnetic current is 1.5A under conditions to obtain a grade of 59% recovery rate of 79.3% iron ore .

Technical Basis

In this study, the fundamental properties of metallurgical solid waste were investigated firstly. Based on which, the experiments of metallurgical solid waste adding in pelletizing process were studied. The results showed that it is possible to add metallurgical solid waste in pelletizing process. But in order to meet the blast furnace production requirements, the ratio of metallurgical solid waste should not be more than 15%, and the roast temperature should be above 1250°C. This work can provide theoretical and technical basis for using metallurgical solid waste in pelletizing process.

Air Speed

From the results calculated by theoretical derivations, it was found that the characteristics of tuyere raceway determined by the operation condition for blast air played a critical effect on the heart activity. The speed and kinetic energy of blast air should be proportional to the volume of blast furnace (BF), and the comprehensive optimization of air volume and tuyere which should vary with the quality of raw materials was essential. The calculation methods of air volume ratio and coefficient for different BFs were put forward. Moreover, the details on hearth activity recovery of a 4747 m3 blast furnace in China were elaborated. Based on the extensive experience in blast furnace production, the various phenomena used to judge air speed and kinetic energy whether reasonable were discussed. In summary, hearth activity was closely related to the characteristics of BF raceway and reasonable air speed and kinetic energy could effectively improve the activity.
