[0131] According to the first embodiment of the present invention, a liquid-gas two-phase medium coupled mobile jet sintering method is provided:
[0132] A liquid-gas two-phase medium coupling mobile injection sintering method, the method includes the following steps: 1) Obtain the particle size D of the current mixture to be sintered; 2) Send the mixture to be sintered into a sintering machine through a trolley for sintering , spray gaseous fuel to the sintering material surface of the trolley in an integral form, and spray liquid fuel to the material surface of the trolley in a moving form; 3) monitor in real time when the mixture to be sintered is sintered on the trolley, and obtain current Water vapor concentration C on the sintered surface 水 and CO 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, select one of the injection sintering methods of pure gaseous fuel sintering, pu...
Embodiment 2
[0134] Repeat embodiment 1, but in step 4), data is substituted into formula (1), obtains the judgment parameter δ of the sintered material surface everywhere in the sintering machine;
[0135]
[0136] Judging the size of δ, choose the injection sintering method:
[0137] When δ≤1, the sintering method of pure gaseous fuel injection sintering is adopted;
[0138] When 1<δ≤2, the sintering method of mixed injection sintering is adopted;
[0139] When δ>2, the sintering method of pure liquid fuel injection sintering is adopted;
[0140] 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 coupling coefficient of particle size, the value is 0.6-1.2; k2 is the coupling coefficient of water vapor concentration, the value...
