Recently, the cadres and employees of Longgang Steel Company of Shaanxi Iron and Steel Group followed the goal of "reducing system cost by another 100 yuan", used their brains, actively explored practice, and innovatively developed a new baking device for blast furnace slag skimmer, and successfully applied it in production .

　　The blast furnace taphole is an important part of the blast furnace ironmaking system. Its function is to separate the slag and iron, lead the molten iron into the molten iron tank, and lead the slag into the slag treatment and crushing device. In actual production, when the blast furnace is pouring new iron ditch, in order to ensure the later life of the iron ditch, the newly poured iron ditch must be baked before it can be used. However, since the baking operation of this unit used the baking method in which the skimmer well was inserted into the homemade baking tube, it not only took more than 12 hours for continuous baking, but the baking tube could not enter the inside of the skimmer, which easily caused iron trough baking. Uneven baking results in a significant shortening of the service life of the new iron groove.

　　 In response, the company established a technical research team, after careful research, finally developed a new baking device for blast furnace slag skimmer. This set of equipment not only shortens the baking time to 8 hours, but also enables the newly cast iron ditch to be put into use 3 hours earlier, and the skimmer bakes evenly, which further guarantees the casting quality of the iron ditch.
