Embodiment Construction
[0062] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows with accompanying drawings:
[0063] See figure 1 with figure 2 , The present invention provides a method for adjusting the alkalinity of sintered ore, which includes the following steps:
[0064] 1) Daily alkalinity adjustment
[0065] In daily production, the alkalinity of sinter inevitably fluctuates. First find out the reason for the change and judge it to be SiO 2 It is also the change in alkalinity caused by the change of CaO. If it is caused by the change of CaO, adjust it according to the following formula to adjust the limestone for flux.
[0066] The adjustment formula is:
[0067]
[0068] Δ—Adjust the percentage of material ratio
[0069] M—Alkalinity target value
[0070] N—average alkalinity value (actual)
[0071] C—Limestone CaO%
[0072] S—average SiO 2 %(actual)
[0073] The adjustment...
