Abstract
Description
Technical Field
[0001] The present application relates to the technical field of steelmaking equipment, and in particular to a swing groove castable baking and sealing insulation equipment. Background Art
[0002] During blast furnace production, the molten iron produced by the blast furnace flows into the molten iron ditch after slag skimming, and then enters the swing ditch through the molten iron ditch. The swing ditch swings to a certain position to accurately send the molten iron into the molten iron tank below, and finally is transported to the next smelting step through the transportation mechanism. Therefore, the swing ditch is an important link in the molten iron transportation process, which can guide the molten iron and control the flow direction and speed.
[0003] Since the molten iron carried by the swing groove has a high temperature and is subject to great impact and erosion, the swing groove needs to be replaced and repaired regularly. This process requires the swing groove to be put back into the mold for casting. After the casting is completed, a large amount of wood needs to be placed above the swing groove for burning and baking, so that the moisture in the castable in the swing groove can be evaporated and burned to form. However, this method takes a long time to bake, consumes a large amount of wood, and the smoke generated by the continuous burning of wood will have a certain impact on the environment. In addition, since the bottom of the swing groove is deep, the baking method of burning wood above the swing groove is not easy to dry the moisture in the castable at the bottom of the swing groove, resulting in moisture at the bottom of the swing groove. If this swing groove is used directly, after the molten iron flows into the swing groove, the high temperature will evaporate the moisture, and the water vapor will splash when it encounters the molten iron, and even cause the swing groove to explode, which will seriously damage the surrounding equipment and pose a great hidden danger to the safety of the operator. Therefore, there is an urgent need for a swing groove castable baking and sealing insulation equipment to improve the above problems. Utility Model Content
