Description
Technical field
The utility model belongs to metallurgical technology field, more particularly to a kind of rotatable fuel gas ejecting device.
Background technique
Combustible gaseous fuel is sprayed on the bed of material surface of sintering machine front end, the surface layer of sinter bed can be improved because of iron ore
Fusion temperature is not enough and high temperature hold time deficiency is easy the phenomenon that generating fragility structure, can be improved the quality of sintering, subtracts
The usage amount of few coke powder or coal dust, is an energy-saving and environment-friendly sintering technology, the spray of sintering charge level plus its uniformity of imflammable gas
It is the key that this technology, the safety that the spray that it is directly related to imflammable gas adds effect and spray to add, this requires expecting
Added-time gaseous fuel is sprayed on the biggish sintering machine of surface layer can quickly mix with air, dilute.
Utility model content
To solve the above problems, the utility model proposes a kind of rotatable fuel gas ejecting device, the devices
Structure is simple, easy to use, uniformly can safely spray to sintering charge level and add imflammable gas, improve sintering quality, reduce
Fuel consumption.
To achieve the goals above, the utility model uses following scheme, comprising:
