본 고안은 용선예비처리작업에서 토페도래들카(TLC)의 용선내의 부원료를 투입하는 경우, 비산되는 용선의 유출을 방지하기 위한 스프래쉬 커버(splash cover)에 관한 것으로, 보다 상세히는, 스프레쉬 커버의 제작시랜스건조로에서 대기로 방출되는 폐열을 이용하여 건조시킴으로서 내구성 향상에 따른 원가절감 및 교환작업의 부하를 경감시킬수 있도록 된 스프래쉬 커버의 건조장치에 관한 것이다.The present invention relates to a splash cover for preventing spillage of molten iron which is scattered when the subsidiary materials of the Tope Ladle Car (TLC) in the molten iron preliminary treatment operation are introduced. The present invention relates to a drying apparatus for a splash cover that can reduce the load of cost reduction and replacement work due to durability improvement by drying using waste heat emitted from the lance drying furnace to the atmosphere during manufacture of the cover.
일반적으로, 용성예비 처리작업에서는 토레도래들카(TLC)(100)내의 용선(110)으로 랜스(120)를 이용하여 부원료를 질소(N2)와 함께 투입시켜 황(S)와 인(P)성분을 조절하고 있다. 이러한 작업과정에서 랜스(120)를 통하여 부원료를 투입하게 되면, 용선(110)이 토페도래들카(100)의 내부로부터 비산하여 외부로 누출되기 때문에, 이를 방지하기 위하여 토페도래들카(100)의 상부에는 스프레쉬 커버(splash cover)(130)가 사용되어 용선(110)의 외부비산을 방지하는 것이다. 그러나, 상기와 같은 스프래쉬 커버(130)는 제 3 도에 도시된 바와같이 내화물 믹서(mixer)(140)에서 캐스타블(castable)내화물(145)을 슈트(147)로 분출하여 몰트케이스(moldcase)(150)에 주입시공한다. 그리고, 캐스타블 내화물(145)이 자연상태에서 양생되면, 몰드케이스(150)를 해체하여 적정장소에서 자연건조시켜 제작하게 되는 것이다. 한편, 상기와같은 종래기술에 따라 제작된 스프래쉬 커버(130)를 사용하게 되면, 자연건조상태에서 제작된 내화물(145)의 내응집성 및 내응고성이 매우 낮고, 또한 건조상태가 불량하기 때문에 내화물(145)에 다량의 습기가 존재함으로써 용선(110)의 고열에 의하여 내화물(145)이 부분적으로 폭발을 일으키게 되고, 이는 내화물(145)의 탈락을 수반하여 스프래쉬 커버(130)의 지지프레임(155)을 용손시켜 구멍(155a)을 형성시키고 마는 것이다. 이러한 스프래쉬 커버(130)의 파손이 발생되면, 즉시 작업을 중단하고, 이를 새것으로 교체시켜야 하기때문에 후공정 조업에도 막대한 지장을 초래하여 작업생산성이 저하됨은 물론, 원가상승을 초래하고, 빈번한 교체작업에 따른 작업자의 부하가 증가되는 문제점을 발생시키게 된다.In general, in the preliminary soluble treatment operation, by using the lance 120 as a molten iron 110 in the Tole Ladle Car (TLC) (100) by adding a secondary raw material with nitrogen (N 2 ) sulfur (S) and phosphorus (P). I regulate the ingredient. When the subsidiary materials are introduced through the lance 120 in this process, the molten iron 110 is scattered from the inside of the torpedo ladle 100 and leaks to the outside. At the top of the splash cover (splash cover) 130 is used to prevent external scattering of the molten iron (110). However, as shown in FIG. 3, the splash cover 130 ejects the castable refractory 145 into the chute 147 from the refractory mixer 140 to the chute 147. moldcase 150). When the castable refractory 145 is cured in a natural state, the mold case 150 is dismantled to be naturally dried at an appropriate place. On the other hand, if the use of the splash cover 130 manufactured according to the prior art as described above, the refractory and solidification resistance of the refractory 145 produced in the natural dry state is very low, and the dry state is poor refractory The presence of a large amount of moisture in the 145 causes the refractory 145 to partially explode due to the high temperature of the molten iron 110, which is accompanied by the dropping of the refractory 145, thereby supporting the support frame of the splash cover 130 ( 155 is forcibly formed to form holes 155a. When the breakage of the splash cover 130 occurs, the work must be immediately stopped and replaced with a new one, thus causing enormous obstacles in post-processing, resulting in a decrease in work productivity, cost increase, and frequent replacement. It causes a problem that the load of the worker according to the work is increased.
