Description
Technical field
The present invention relates to a kind of methods for preparing cooled agglomerated pellet using revolving furnace mud.
Background technique
Coal-pressing ball is that fine grinding concentrate is made to a process for being able to satisfy the block material for smelting pressure ball, i.e., one
Under constant-pressure, press to powder material in a model with certain shapes, size, the slight block material of density.At
It generally also needs to make the agglomerate with higher-strength by consolidating accordingly after block.In pellet preparation process, object
Material is not only due to particle and the variation in physical property (density, porosity, shape, size and mechanical strength etc.) intensively occurs,
And chemically and physically chemical property (chemical component, reproducibility, reduction swellability, low-temperature reduction disintegration energy, height has occurred
Temperature reduction softening performance, molten drop performance etc.) on variation, so that enabling the metallurgical performance of material is improved.But it is existing
Method it is more complicated, and expend a large amount of manpower and material resources, while also having very big pollution to environment.
Summary of the invention
An object of the present invention is to provide a kind of methods for preparing cooled agglomerated pellet using revolving furnace mud.
The method for preparing cooled agglomerated pellet using revolving furnace mud of the invention, includes the following steps: S101: first drying revolving furnace mud
It is dry, the binder of its weight percent 0.1%~3% is then added in revolving furnace mud, then described will be turned with strength ball press
Furnace mud briquetting；S102: the processed revolving furnace mud of step S101 is stood at room temperature, obtains cooled agglomerated pellet.
The method for preparing cooled agglomerated pellet using revolving furnace mud of the invention, discarded revolving furnace mud is recycled, and utilization rate reaches
To 80%, in addition, method green of the invention, pollution-free, it is energy saving, there is good commercial promise.
In addition, the device of above-mentioned strong brine low temperature crystallization desalination of the invention, can also have following additional technology special
Sign:
Further, in the step S101, the temperature of drying is 50 DEG C~70 DEG C, and drying time is 4h~6h.
Further, in the step S101, when with the strength ball press by the revolving furnace mud briquetting, pressure is
20MPa~40MPa.
Further, in the step S102, time of repose is for 24 hours~36h.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
