Description
Technical field
The present invention relates to a kind of processing system of oxide scale residue and method more particularly to oxide scale residue drainings and transfer
System and method.
Background technique
Oxide skin is also known as iron scale, iron scale, is in heat steel and the operation of rolling, since surface is aoxidized and shape
At iron oxide layer, the fish scale-shaped object to get off is peeled off, external appearance characteristic is rigid gray pieces and grey black fine particle and powder, broken
Metallic luster is presented in piece, enbrittles, and fracture is in cellular.The main component of iron oxide is FeO, and contains a small amount of Fe3O4,
Sample main component is Fe 70.20%, Mn 0.49%, Ca 0.52%, Al 0.02%, Ti 0.02%, Cu 0.04%, and oxide skin
It is to necessarily lead in heat steel and the operation of rolling, does not can avoid, since its Fe content is higher, usually can be used as ferrosilicon
The raw materials for production of alloy or ferro-boron, the part that also can be used as blast furnace ironmaking add raw material.
It is mainly in the prior art that waste water for flushing collects oxide scale residue for the processing mode of oxide skin, it is then naturally dry
It is dry, when iron oxide water content is lower than 5% or less, it is just conveyed to raw material of the ferrosilicon factory as Antaciron, then due to steel heat
The process of rolling is usually whole day continuous production, can endlessly generate iron scale, and iron scale is usually mixed with waste water, defeated
It send to wastewater trough, wherein the content of waste water is up to 70 ~ 80%, accumulation after then salvaging the iron oxide waste residue in wastewater trough,
Oxide skin/(oxide skin+waste water) ratio is also up to 20 ~ 30%, and the way of usual steel rolling mill is heap after salvaging iron oxide waste residue
It puts, spontaneously dries evaporating waste water or by seeping waste water naturally, after usually standing 1 ~ 2 week, the water content of waste residue can just be lower than
5%, it is too long to stand the water removal time cycle.And for steel rolling mill, the iron oxide waste residue monthly generated is up to 1000 ~ 2000
Ton is such as handled not in time, can seriously be accumulated, and occupies workshop position, wastes land resource, and the oxide skin stacked be easy to cause powder
Dustiness dye (for the size of usual iron scale between 1mm ~ 5cm, wherein powder be easy to cause pollution, and wastes iron resource), this
Outside, other than natural evaporation, dry waste water, waste water can also penetrate into soil, cause land pollution, due to permeating for a long time, very
Be easy to cause the collapsing of wastewater trough, bring security risk (place that usual oxide scale residue is stacked close to wastewater trough, thousands of tons of
Waste residue will cause wastewater trough groove body rupture), i.e., existing processing iron oxide waste residue when have the following problems: (1) oxide skin dry
Period is too long；(2) oxide skin, which is stacked, occupies a large amount of soils；(3) seep to oxide skin waste water that there are security risks；(4) period is stacked
It is too long to will lead to dust pollution, iron resource waste；(4) oxide skin salvaging is mainly salvaged manually.
In addition, the departments such as State Environmental Protection Administration in No. 11 bulletins of publication in 2008 " limiting inlet class is available
Make the solid waste catalogue of raw material " in list the oxide skin of Rolling production, therefore oxide skin belongs to the solid of limiting inlet
Waste, value as it can be seen that it is reported that, in the production process of ferrosilicon, iron oxide as main raw materials requirement amount it is continuous on
It rises, the ferrosilicon of usual 75# is at 5000-7000 yuan/ton, and the price of oxide skin is at 400 ~ 900 yuan/ton, and ferrosilicon factory is for oxidation
The requirement of skin is that iron-content is higher than 65%, and water content is lower than 5%, and at this moment, there have been obvious problems: the iron oxide of steel plant contains
Water is excessively high, cannot dry and accumulate, the oxide skin that ferrosilicon factory needs largely to dry again in time, and steel plant cannot use specially
Drying equipment dries oxide skin waste water slag, and (mainly since water content is excessively high, and the oxide skin of thousands of tons of is set using drying
Standby dry, increased costs are 100 ~ 200 yuan/ton), therefore steel plant would generally handle oxidation using the method spontaneously dried
Skin, to restrict the production of ferrosilicon.
Summary of the invention
