本発明は転炉スラグコーテングにおける水冷装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water cooling device for converter slag coating.
転炉スラグコーテングは従来時分５０−４０３６４等に
示すように、転炉出鋼後桟スラグに固化材を添加して首
振り後コーテング部位を下側にして転炉４体を静止させ
、該スラグが自然冷却し固化するのを待つ方法である。Conventionally, converter slag coating is carried out by adding a solidifying agent to the crosspiece slag after tapping the converter, and after shaking the converter, the four bodies of the converter are held still with the coated part facing downward. This is a method of waiting for the slag to cool naturally and solidify.
しかし上記のごとき放冷Ｋまかせていたならば当該コー
テングスラグが冷却固化するまでに長時間を要し、この
間転炉の操業停止は余儀なくされ、著しい生産低下に繋
っていた。However, if the coating was left to cool as described above, it would take a long time for the coating slag to cool and solidify, forcing the converter to shut down during this time, leading to a significant drop in production.
この対策として該コーテング部の強制空冷や、水冷を容
易に考えることができるが強制空冷では冷却効果が非常
に低く、また単なる散水冷却では冷却効果を有するが冷
却完了後の転炉後転時に起りうる水蒸気爆発の防止と冷
却過多による熱損失も多く、水蒸気爆発は設備破損はも
とより、人災に繋がる可能性が高いので好ましくない。As a countermeasure to this problem, forced air cooling or water cooling of the coating section can be easily considered, but forced air cooling has a very low cooling effect, and simple water cooling has a cooling effect, but the problem occurs when the converter is rotated after cooling is completed. There is also a lot of heat loss due to the prevention of steam explosions and excessive cooling, and steam explosions are undesirable because they not only damage equipment but also have a high possibility of leading to human disasters.
本発明は前記従来法の欠点、対応策の危険性を解消する
ためには冷却効果がある散水方法で冷却しかつ水蒸気爆
発°の危険性を排除する、冷却装置を必要とする。In order to eliminate the disadvantages of the conventional methods and the risks of countermeasures, the present invention requires a cooling device that uses a water spray method that has a cooling effect and eliminates the risk of steam explosion.

(Approximately 1) Atmospheric gas 7' is sucked in at any specified location, and the moisture content is measured with a moisture analyzer 15 and compared with a standard value to confirm safety. Thoroughly observe the interior to confirm that there is no water puddle formation, and quantitatively determine the amount of water (
After air-water spray cooling begins, the water content decreases over time and reaches the safety standard value. ), so safety can be ensured the next time the molten gun is received into the converter. Furthermore, since these devices can be operated remotely and rationally, they are extremely effective in shortening working time, saving manpower, and in terms of safety.
第６図、第７図において本発明装置の操業について説明

確認する。The converter F'l coats the remaining slag 5 downward with the swinging action F and remains stationary, and travels over the furnace front operating floor 2 through the opening 4' of the smoke prevention plate 4 located in front of the converter l. The truck 3, which has stopped at a fixed position, advances its arms 8, 8' and sprays a stream of air and water 34 from the spray nozzle 6, thereby cooling the surface of the coating slag 5 at an optimum speed. After cooling, the arm 8.8' is reversed and the atmospheric gas 7' is sucked through the detection nozzle 7 and analyzed and detected by the moisture detection device 15, which will be described later, to confirm that there is no risk of a steam explosion or the like.
