Technical Field
The utility model relates to a metal smelting technical field especially relates to an online device of handling hot metal bottle jar mouth crusting.
Background
The hot metal bottle is a container for transporting molten iron in iron and steel metallurgy enterprises, and because the heat dissipation of the mouth part of the hot metal bottle is fast, a circle of crusting of annular iron slag is often formed near the mouth of the hot metal bottle due to the fast drop of the temperature, and the crusting is particularly easy to form in a blast furnace for smelting vanadium-titanium magnetite. When the blast furnace conditions for smelting the vanadium-titanium magnetite are abnormal, the temperature of the discharged molten iron is lower or higher, and the mouth of the molten iron tank is more likely to be crusted.
The more the hot metal ladle is used, the larger the annular crusting area and the annular crusting volume are. The incrustation area is increased, so that the mouth of the hot metal ladle is smaller and smaller, when the locomotive pulls back an empty ladle, the working of the mouth of the hot metal ladle and the opening of the blast furnace platform molten iron ditch is aligned to cause larger influence, and even the situation that the hot metal ladle cannot be aligned and cannot be used is caused. In addition, because the opening of the tank is small, part of iron flow impacts the crusts to splash outwards during tapping, and smoke dust or safety accidents are easy to occur. Moreover, after the hot-metal bottle is used for many times, the incrustation volume is gradually increased, the volume of the hot-metal bottle is gradually reduced, and the amount of hot-metal water is less and less.
At present, when the hot metal bottle crusts seriously, the hot metal bottle is pulled to a repair tank room, and the oil hammer is used for treating the crusting of the hot metal bottle. However, the method can damage the refractory materials of the hot-metal ladle and influence the reuse of the hot-metal ladle.
