Embodiment 1
[0048] to combine figure 1 , figure 2 , image 3 and Figure 4 , a device for simulating different atmospheres to detect the assimilation temperature of iron ore powder in this embodiment includes a heating unit 100, a detection unit 200 and a gas supply unit 500; wherein the heating unit 100 includes a sample stage 110 and a heating furnace 120, and the sample stage 110 is arranged in the heating furnace 120, and the heating unit 100 is used to heat the iron ore powder sample 400 on the sample table 110. The top of the heating furnace 120 is provided with a gas outlet 121; the heating furnace 120 is tested by an electric heating wire. The iron ore powder sample 400 on the sample platform 110 is heated up (as figure 1 shown), of course, the heating furnace 120 can also be heated in other ways, for example: infrared heating and the like.
[0049] The gas supply unit 500 includes a gas supply cylinder 510, a flow meter 520 and a gas supply pipeline 530; the gas supply cylin...
Embodiment 2
[0061] The basic content of this embodiment is the same as that of Embodiment 1, and the difference is that the temperature-measuring thermocouple 240 is provided with a thermocouple horizontal section 241, and the temperature-measuring end 243 is arranged at the end of the thermocouple horizontal section 241 (such as figure 2 As shown), the thermocouple horizontal section 241 is arranged in the sample pressing part 211, and the temperature measuring end 243 is located at the edge of the sample pressing part 211, that is, the end of the thermocouple horizontal section 241 extends to the iron ore powder sample The edge position of 400, the temperature measuring end 243 of the temperature measuring thermocouple 240 is close to the edge position of the iron ore powder sample 400, thereby improving the accuracy of the temperature detection around the iron ore powder sample 400, and then improving the iron ore powder assimilation temperature The accuracy of detection provides relia...
Embodiment 3
[0064] The basic content of this embodiment is the same as that of Embodiment 1, the difference is that: the temperature measuring end 243 is connected with the auxiliary temperature measuring rod 242, the auxiliary temperature measuring rod 242 is arranged at the edge position of the sample pressing part 211, and the auxiliary temperature measuring rod 242 is set along the vertical direction; the distance between the auxiliary temperature measuring rod 242 and the edge of the iron ore powder sample 400 is L, then 1mm<L<2mm, the present embodiment L=1.5mm, the material of the auxiliary temperature measuring rod 242 is carbonization Silicon; the auxiliary temperature measuring rod 242 is arranged parallel to the edge of the iron ore powder sample 400 , and the bottom of the auxiliary temperature measuring rod 242 is in contact with the surface of the CaO pressure sheet 111 . The auxiliary temperature measuring rod 242 of this embodiment is close to the edge of the iron ore powde...
