AI Technical Summary

Technical Problem

Existing heat dissipation devices for metallurgical furnaces have complex structures, are cumbersome to disassemble and assemble, are difficult to maintain, and pose a danger by using water as a heat dissipation medium.

Method used

The furnace body heat dissipation device consists of a fan and a base, using air as the heat dissipation medium. Cold air enters the furnace body from the air outlet of the insertion part, while hot air moves along the gap between the outer wall of the insertion part and the inner wall of the furnace body and is discharged from the heat dissipation plate. The cold and hot air flow channels are separated to avoid the cold and hot air flow from colliding.

Benefits of technology

It achieves a simple structure, convenient disassembly and assembly, avoids contact between water and liquid metal, eliminates the possibility of steam explosion, and improves heat dissipation efficiency.
