Embodiment approach
[0094] According to the first embodiment of the present invention, a liquid-gas two-phase medium coupling partition injection sintering method is provided:
[0095] A liquid-gas two-phase medium coupling partition injection sintering method, the method includes the following steps: 1) obtaining the particle size D of the current mixed material to be sintered; 2) sending the mixed material to be sintered into a sintering machine through a trolley for sintering , spraying gaseous fuel and liquid fuel to the material surface of the trolley in the form of partitions; 3) real-time monitoring when the mixture to be sintered is sintered on the trolley, to obtain the water vapor volume concentration C on the sintered material surface in each partition 水 and CO volume concentration C CO ; 4) according to step 1) and step 3) data D, C 水 、C CO , compare it with the historical average data stored in the system, so that one of the injection sintering methods of pure gaseous fuel sinterin...
Embodiment 1
[0129] According to the first embodiment of the present invention, a liquid-gas two-phase medium coupling partition injection sintering method is provided:
[0130] A liquid-gas two-phase medium coupling partition injection sintering method, the method includes the following steps: 1) obtaining the particle size D of the current mixed material to be sintered; 2) sending the mixed material to be sintered into a sintering machine through a trolley for sintering , spraying gaseous fuel and liquid fuel to the material surface of the trolley in the form of partitions; 3) real-time monitoring when the mixture to be sintered is sintered on the trolley, to obtain the water vapor volume concentration C on the sintered material surface in each partition 水 and CO volume concentration C CO ; 4) according to step 1) and step 3) data D, C 水 、C CO , compare it with the historical average data stored in the system, so that one of the injection sintering methods of pure gaseous fuel sinterin...
Embodiment 2
[0132] Repeat embodiment 1, just step 4) in data D, C 水 、C CO Substitute into formula (1) to obtain the judgment parameter δ of each partition above the trolley;
[0133]
[0134] Judging the size of δ, choose the injection sintering method:
[0135] When δ≤1, the sintering method of pure gaseous fuel injection sintering is adopted;
[0136] When 1<δ≤2, the sintering method of mixed injection sintering is adopted;
[0137] When δ>2, the sintering method of pure liquid fuel injection sintering is adopted;
[0138] Among them, D, C 水 、C CO The units are mm, %, %; D 平均 is the historical average particle size of the mixture to be sintered, mm; C 水平均 is the historical average volume concentration of water vapor during sintering, %; C CO平均 is the historical average volume concentration of CO during sintering, %; k1 is the particle size coupling coefficient, which takes a value of 0.7; k2 is the water vapor concentration coupling coefficient, which takes a value of 0.5; k3...
