Mouth machine 530 and cover carriage 540 are electrically connected with information control harvester 400, and described information control harvester 400 can gather clay gun
520th, the kinestate of tapping machine 530 and cover carriage 540.Tapping hole is opened during being used to tap a blast furnace by tapping machine 530, clay gun
520 for tapping hole is blocked up, and the cover plate on iron tap channel 100 is removed or resetted during being used for tapping hole by cover carriage 540, from
And be that the opening of tapping machine 530 and clay gun 520 are blocked up and provide space.
As shown in figure 4, a kind of On-line Measuring Method of large blast furnace molten iron temperature of the present embodiment, step is as follows：
Step 1：Determine tapping position, large blast furnace typically possesses multiple tapping holes, therefore in the mistake of measurement molten iron temperature
Cheng Qian typically will first determine the tapping hole for this time tapping a blast furnace, and gather the positional information of clay gun 520, tapping machine 530 and cover carriage 540,
After cover plate is removed by cover carriage 540, the time for gathering the accumulative continuous rotation strike tapping hole of tapping machine 530 is t1, when t1 >=
During 5min, determine that the 540 corresponding tapping hole of cover carriage is the tapping hole that this taps a blast furnace, the predetermined thermometric time is set for tmi；When
t1<5min, then not can determine that this tapping hole position tapped a blast furnace；
Step 2：Effective tapping duration is calculated, after determining tapping position, tapping machine 530 returns to home position, then takes off lid
It is tc that 100 cover plate of iron tap channel is covered start recording tapping duration by machine 540, what deserves to be explained is tc is a dynamic time,
Which starts the time accumulated from 100 cover plate lid of iron tap channel until tapping a blast furnace stop recording of formally terminate, wherein during tapping a blast furnace by
When blast fumance does not smoothly cause time-out to tap a blast furnace, tc does not stop timing, and only when the tapping hole, this taps a blast furnace
Tc is recorded only；Effective tapping duration Tc is calculated then, wherein Tc is the function with regard to tc；
If (2-1), blast fumance is smoothly, and tapping hole taps a blast furnace smoothness, then Tc=tc；
If (2-2) tapping hole taps a blast furnace not smooth, need to carry out supplementary opening to tapping hole, when sending supplementary opening information
The tapping duration of tapping hole is t2, and when sending opening information, cover carriage 540 is again started up removing cover plate, and tapping machine 530 is again
Home position is returned to after the completion of rotation strike tapping hole, then cover plate is resetted by cover carriage 540 again；If t2 >=20min, remember
Effective tapping duration Tc=tc-t2 is recorded, if t2<20min, then record effective tapping duration Tc=tc-t2-10；This time, tapping machine
530 again rotation strike tapping hole in order to tapping hole is dredged again, so as to tap a blast furnace offer guarantee for tapping hole smoothness；
If (2-3) blast fumance has some setbacks, need to block tapping hole and suspend and tap a blast furnace, send cover carriage 540 when blocking up information
It is again started up removing cover plate, tapping hole is blocked by clay gun 520, ferrum mouth can be again turned on continuing after blast fumance is smooth
Cover plate is resetted by ferrum, cover carriage 540, and cover plate was removed between the time for resetting again by the information control collection cover carriage 540 of harvester 400
It is divided into t4；The tapping duration for sending tapping hole when blocking up information is t3；
If t3 >=30min, if t4 >=25, Tc=tc-t3-t4；If 25>T4 >=15, then Tc=tc-t4-20；If t4<
15, then Tc=tc-t4-10；If t3<30min, if t4 >=15, Tc=tc-t3-t4；If t4<15, then Tc=tc-t3-t4+
5。
Step 3：Determine thermometric opportunity, hand-operated temperature-measuring is collected when accumulative tapping duration reaches the default thermometric time or works as
Signal, control temperature measuring equipment carry out thermometric；
(3-1) when without hand-operated temperature-measuring signal, Tc=tmiWhen, molten iron temperature measuring unit 300 starts thermometric；
(3-2) when there is hand-operated temperature-measuring signal, then thermometric immediately, and to application when effectively tapping a blast furnace when recording hand-operated temperature-measuring
Between the time interval of first default point for measuring temperature after Ts, i.e. hand-operated temperature-measuring point and hand-operated temperature-measuring degree be t△, work as t△<When 10, then handss
First default point for measuring temperature no longer thermometric after dynamic thermometric, the normal thermometric of other points for measuring temperature；Work as t△When >=10, all default points for measuring temperature
Normal thermometric.
Step 4：Measurement molten iron temperature
If information control harvester 400 is collected is provided with thermocouple on temperature-measuring gun 316, temperature-measuring gun 316 is directly by warm
Galvanic couple is compressed, and is then driven thermocouple to insert by temperature-measuring port 210, is carried out molten iron thermometric；If information control harvester 400 is collected
Thermocouple is not installed on temperature-measuring gun 316, then temperature-measuring gun 316 is moved to thermocouple holding structure 320 and installs thermocouple, then thermometric
Rifle 316 drives thermocouple to insert by temperature-measuring port 210, carries out molten iron thermometric；
If (4-1) thermocouple measures molten iron temperature between 1250-1600 DEG C, the normal thermometric of thermocouple is represented, thermometric is complete
Rapidly thermocouple is lifted into rear, fire extinguishing process is carried out to thermocouple, and thermocouple is reclaimed, be that next thermometric is standby,
This time thermometric terminates；Wherein described fire extinguishing is processed as：Thermometric terminates rear galvanic couple separating component 315 and moves downward a segment distance,
Move distance is 1-2cm, so that thermocouple is partially separated with temperature-measuring gun 316, when thermocouple is partially separated with temperature-measuring gun 316
When, when reusing, temperature-measuring gun 316 carries out thermometric, the first fire extinguishing groove 331 and the second fire extinguishing groove by directly compress thermocouple
332 opposite motions, so as to increase spacing between the two, are easy to temperature-measuring gun 316 to drive thermocouple to move to the first fire extinguishing groove 331
And second between fire extinguishing groove 332, then the first fire extinguishing groove 331 and the second fire extinguishing 332 move toward one another of groove thermocouple is clamped, from
And thermocouple anoxybiotic is put out a fire；
If (4-2) thermocouple measures molten iron temperature and thermometric registration is not shown between 1250-1600 DEG C or not, then it represents that
Thermocouple is lifted after the completion of thermometric rapidly by thermometric exception, and galvanic couple separating component 315 moves downward 5-15cm, so that hot
Galvanic couple is kept completely separate with temperature-measuring gun 316, and thermocouple is discarded, and then temperature-measuring gun 316 is moved to thermocouple holding structure 320,
Temperature-measuring gun 316 reinstalls thermocouple, and replication molten iron temperature, until the normal thermometric of thermocouple.
