When the slag is slowly cooled, the slag is naturally and slowly cooled in a slow cooling field, and when the slag is cooled to the target temperature, cooling water is sprayed to the slag ladle to accelerate the cooling speed, promote crystallization and precipitation to obtain larger crystals, and facilitate subsequent ore dressing. The temperature of each slag ladle can be known in time, whether the slag ladle enters a water cooling stage or not and the residual cooling time can be judged, and the slag slow cooling process is optimized.
Chinese patent CN106319113A discloses a slag ladle cooling device, which is provided with an infrared temperature measuring device on the top of the slag ladle through a support frame. Because there may be the difference in temperature in cinder ladle top and bottom, and in the water-cooling process, the cinder upper strata is full of cooling water in the cinder ladle, and the temperature data that infrared temperature measuring device surveyed from the cinder ladle top can't be used for judging the slag slow cooling condition.

Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
A high-temperature melt slow cooling device is characterized in that a slow cooling area 20 used for stacking a slag ladle A is arranged beside a track 11 of a portal crane 10, a temperature measuring probe 30 is arranged on a supporting leg 12 of the portal crane 10, and the temperature measuring probe 30 obliquely points downwards to the side wall of the slag ladle A in the slow cooling area 20. Therefore, the temperature information of the side wall of the slag ladle A can be effectively collected under the condition that the distance between the slag ladle A and the supporting leg 12 is small, and the temperature measuring probe 30 is positioned above the slag ladle A, so that the phenomenon that sprayed or overflowing cooling water splashes and adheres to the temperature measuring probe 30 to affect the temperature measuring effect can be avoided.
As shown in fig. 1-4, in the present embodiment, the slag ladles a in the slag ladle stacking area 20 are sequentially arranged along the extending direction of the rail 11 to form a slag ladle column, and one temperature measuring probe 30 can only detect and measure the temperature of a single slag ladle column. The side of the slag ladle A is provided with a spraying device which comprises a spraying port 41 positioned above the slag ladle A and a spraying pipe column 42 standing beside the slag ladle A. The cooling water flows to the upper opening of the slag ladle A from the spray nozzle 41, and overflows along the side wall of the slag ladle A to fully cool the slag ladle A.
In order to ensure that the temperature measuring probe 30 can fully acquire the temperature information of the side wall of the slag ladle A and ensure the reliability of the measured temperature. The lowest part of the detection range of the temperature measuring probe 30 is not higher than the 1/4 height of the slag ladle A, namely, the side wall of the slag ladle A above the bottom 1/4 height is positioned in the detection range of the temperature measuring probe 30. The core shaft of the temperature measuring probe 30 and the plumb bob face are arranged at an included angle, so that the temperature measuring probe 30 is slightly deviated to the front or the rear, and when the spraying pipe column 42 is positioned between the slag ladle A and the portal crane track 11, the spraying pipe column 42 can be avoided to measure the temperature of the slag ladle A.

A. in the running process of the gantry crane 10, the temperature measuring probe 30 acquires an image of the temperature to be measured; in order to avoid redundancy of temperature measurement information, the temperature measurement probe 30 stops image acquisition after the stop time of the gantry crane 10 exceeds the preset standby time.
B. Analyzing the image to be measured, and identifying an effective area in the image;
in this embodiment, the effective temperature measurement area is a side wall of the thermal slag ladle to be measured in the temperature image to be measured.
Preferably, the area, which is in line with the profile of the side wall of the slag ladle and has the temperature higher than 50 ℃, in the temperature image to be measured is regarded as the side wall of the slag ladle to be measured.
