Embodiment 1
[0063] A kind of on-line measuring method of molten iron temperature of large-scale blast furnace of the present invention, the steps are as follows:
[0064] Step 1: Determine the tapping position, collect the position information of the mud cannon 520, the tapping machine 530 and the capping machine 540, and collect the accumulative time for the tapping machine 530 to continuously rotate and hit the tapping hole after the capping machine 540 removes the cover plate It is t1=10min, when t1=10≥5min, determine that the taphole corresponding to the uncapping machine 540 is the taphole for this tapping, and set the scheduled temperature measurement time as t mi , where t m1 =60,t m2 =80,t m3 =100min; that is, temperature measurement is performed when the effective tapping time reaches 60, 80 and 100min;
[0065] Step 2: Calculate the effective tapping time. After determining the tapping position, the tapping machine 530 returns to the original position, and then the uncapping ...

[0070] A kind of on-line measuring method of molten iron temperature of large-scale blast furnace of the present invention, the steps are as follows:
[0071] Step 1: Determine the tapping position, collect the position information of the mud cannon 520, the tapping machine 530 and the capping machine 540, and collect the accumulative time for the tapping machine 530 to continuously rotate and hit the tapping hole after the capping machine 540 removes the cover plate It is t1=10, when t1=10≥5min, determine that the taphole corresponding to the uncapping machine 540 is the taphole for this tapping, and set the scheduled temperature measurement time as t mi , where t m1 =60,t m2 =80,t m3 = 100; that is, the temperature is measured when the effective tapping time reaches 60, 80 and 100 minutes;
[0072] Step 2: Calculate the effective tapping time. After determining the tapping position, the tapping machine 530 returns to the original position, and then the uncapping machine 5...

[0078] A kind of on-line measuring method of molten iron temperature of large-scale blast furnace of the present invention, the steps are as follows:
[0079] Step 1: Determine the tapping position, collect the position information of the mud cannon 520, the tapping machine 530 and the capping machine 540, and collect the accumulative time for the tapping machine 530 to continuously rotate and hit the tapping hole after the capping machine 540 removes the cover plate For t1=8min, when t1=10≥5min, determine that the taphole corresponding to the uncapping machine 540 is the taphole for this tapping, and set the scheduled temperature measurement time as t mi , where t m1 = 60min; that is, the temperature is measured when the effective tapping time reaches 60min;
[0080] Step 2: Calculate the effective tapping time. After determining the tapping position, the tapping machine 530 returns to the original position, and then the uncapping machine 540 covers the tapping channel 100 c...
