Embodiment Construction
[0032] The present invention takes iron ore powder A and iron ore powder B contained in a certain iron ore powder for production as an example, and tests the assimilation amount of each particle size and the CaO consumption speed of assimilation. Step (1) and (2) of the two test methods are the same:
[0033] (1) First test the alkalinity R, coal mixing ratio and water content of the 4 particle sizes of 0-2mm, 2mm-3.15mm, 3.15mm-5mm and 5mm-6.3mm iron ore powder for production, see the table 1.
[0034] Table 1 produces the flux, fuel and moisture of each particle size of the mixed mineral powder
[0035]
[0036](2) According to the alkalinity R and coal ratio of the above test particle size, prepare four kinds of iron ore powder A and iron ore powder B respectively 0-2mm, 2mm-3.15mm, 3.15mm-5mm and 5mm-6.3mm. Alkalinity R, Coal Ratio and Moisture of Grade Size.
[0037] (1) Test of the assimilation amount of iron ore powder in each particle size:
[0038] (3) Weigh 50...
