Description

Technical Field

[0001] The utility model relates to the technical field of smelting devices, in particular to a stable smelting device for pelletized ore. Background Art

[0002] Pelletized ore is a type of concentrate, usually spherical particles made from powdered iron ore through a series of processes. These particles are processed through a ferroalloy electric furnace. The equipment is stable in use, and the pelletized ore produces iron and steel at high temperatures.

[0003] During the use of the ferroalloy electric furnace, the high temperature generated by the heating component will be transferred to the outside, causing the furnace body to be highly heated, which not only increases the temperature of the working environment and makes the working environment hot and dry, but also the dissipated heat cannot be effectively utilized, resulting in a waste of waste heat resources. For this reason, we propose a pellet ore stable smelting device to solve the existing problem. Utility Model Content
