Description

Technical Field

[0001] The utility model relates to the field of ladle baking devices, in particular to a safety protection device for a ladle baking device. Background Art

[0002] Ladle is used in steel mills and foundries to receive molten steel and perform pouring operations in front of open hearth furnaces, electric furnaces or converters. After being newly built and before being filled with molten steel, the ladle usually needs to be baked with a ladle baker. The ladle baker generally includes a cover, a burner, a gas pipeline and a gas delivery device. The gas pipeline sprays fire into the ladle through the burner, and the gas delivery device also delivers gas into the cover through the burner to achieve baking of the ladle.

[0003] For example, a safety protection device for a ladle baking device with publication number CN219665104U, in which the ladle baking device is placed inside a buffer sleeve from above the buffer sleeve, can assist in rapid positioning of the ladle baking device, and then quickly pre-embed and ensure the accuracy of pre-embedding of the ladle baking device, thereby avoiding pre-embedding errors or inaccurate positioning affecting the use of the ladle baking device. At the same time, when the ladle baking device shakes, the buffer sleeve moves forward, backward, left and right on the inside of the buffer box and transmits the force to the buffer structure, which reacts to the buffer sleeve under the elastic support of the buffer structure, thereby buffering and protecting the ladle baking device from shaking, thereby avoiding the safety hazard of surface friction damage caused by long-term use of the ladle baking device. However, the support frame, buffer sleeve, buffer box and flamethrower of the ladle baking device are fixed as a whole, and according to actual needs, there are differences in the height size of the ladle.
