Description

Technical Field

[0001] The utility model relates to the technical field of steel ladles, in particular to a steel ladle series baking device. Background Art

[0002] At present, ladle baking technology still mainly uses the ancient traditional method. Each ladle requires an independent fire source, which is gradually baked from room temperature to high temperature, about 1150℃. Taking a ladle with a capacity of 100t of molten steel as an example, its heat capacity is about 4.14×106 kcal. However, it takes 60 to 100 hours to bake such a ladle. During the baking process, the heat generated by burning gas is as high as 39×106 kcal, but only about 10.6% of the heat, that is, 4.14×106 kcal, is effectively used for baking the ladle, while the remaining about 89% of the heat is not used, resulting in a huge waste of energy.

[0003] However, a large amount of waste heat is wasted, resulting in low production efficiency. The device can introduce part of the waste heat into the preheated low-temperature ladle for low-temperature baking, thereby increasing the heat utilization efficiency. Utility Model Content
