Ramming Mass Introduce
Ramming mass is granule or powder shape material made from refractory raw material, usually, there are some proportion of binder, after rational gradation and tempering, loose amorphous ramming mass is produced. It is similar to dry-hardened castable, but some ramming mass doesn’t have self-setting binder, so fierce ramming should be applied during construction, that’s why it is called ramming mass.
The Composition of Ramming Mass and Application:
Name | Composition | Application | Note |
Carbon packing material | Metallurgical coke powder(less than 4mm) 80% | The gap between blast furnace base clay brick masonry and furnace shell, blast furnace hearth, the gap between furnace hearth clay brick or high alumina masonry and surrounding cooling wall | Volume ratio |
Carbon ramming mass | Metallurgical coke powder(less than 4mm) 85% | Blast furnace lining | (mass ratio) |
Magnesia ramming mass | Magnesia sand (granularity ≤5mm) 85% | Lateral lifting open hearth furnace bottom | (Volume ratio) |
Magnesia sand 89%~91.5% | Electric furnace bottom | (mass ratio) | |
Magnesia sand 89% | Electric furnace bottom and ramp | Mass ratio | |
Chrome plastic refractory | Chromite 97% | Soaking pit hearth central part, burner nozzle surrounding | (mass ratio) |
Magnesia ramming mass | Magnesia sand 50% | Soaking pit hearth central part, burner nozzle surrounding | (mass ratio) |
Chrome oxide ramming mass | Chromite (granularity ≤3mm) 90% | Circular heating furnace bottom | (volume ratio) |
