Description

Technical Field

[0001] This utility model relates to the field of chute heating technology, and more specifically, to a detachable chute heating device. Background Technology

[0002] A chute is an inclined channel used to transport high-temperature molten metal or slag, commonly found in the metallurgical and foundry industries. The main purpose of heating the chute is to prevent the metal or slag from solidifying due to temperature drop during transport, ensuring smooth material flow and preventing blockages. Furthermore, heating reduces the temperature difference between the molten metal and the chute's inner wall, lowers thermal stress, and extends the service life of the chute's refractory material. In continuous production processes, stable temperature control is crucial for ensuring product quality and production efficiency.

[0003] Most existing chute heating devices are fixedly installed on the chute or embedded inside the chute. When damage occurs, they are not easy to disassemble, and the damaged parts cannot be disassembled and replaced separately, resulting in high maintenance costs. Utility Model Content
