Description

technical field

[0001] The invention relates to the technical field of iron and steel metallurgy, in particular to an energy-saving and consumption-reducing scrap steel preheating spray gun. Background technique

[0002] With the rapid development of the national economy, the cumulative amount of steel scrap in my country is increasing rapidly. Whether it is the converter steelmaking process or the electric furnace steelmaking process, improving the effect of energy saving and emission reduction and improving the utilization rate of valuable elements in scrap steel are the current developments in the field of iron and steel metallurgy technology. problems that need to be faced.

[0003] Under normal conditions, scrap preheating can shorten the production rhythm of the converter process and the electric furnace steelmaking process, and improve production efficiency. At present, many steel mills add steel scrap to iron ladle or steel ladle, and then use traditional baker burne...
