Description
Technical field
It is especially a kind of that environmental protection is made using stainless steel waste residue the present invention relates to stainless steel waste residue utilization technology field
Non-burning brick method.
Background technology
The main component of stainless steel waste residue is the oxides such as calcium, iron, silicon, magnesium, aluminium, manganese, phosphorus, stainless steel waste residue main source
Molten iron is with the oxide formed after contained element oxide in steel scrap in stainless steel fusion process, the impurity that metal charge is brought into,
The slag former of addition such as lime stone, fluorite, silica etc., and oxidant, desulfurization product and furnace lining material for being etched etc..
China's stainless steel waste residue typically makees flux in iron company's inner loop use, return blast furnace or sintering instead of lime
Iron-smelting raw material be used as in stove, it can also be used to highway subgrade, railway bed and conduct cement raw material, improved soil etc., can be used as
Metallurgical raw material；Further, since stainless steel waste residue rubble has, density is big, intensity is high, rough surface, stability are good, it is wear-resisting with it is resistance to
Long property is good, the features such as being firmly combined with pitch thus is widely used in railway, highway and engineering and backfills, particularly suitable for marsh, seabeach
Build the road and make ground；Stainless steel slag can also be applied to cement as the raw material and adulterant for producing no first-hand datum or cement with little clinker,
It can be used for preparing non-burning brick construction material of Denging, however, building containing unstable materials such as free calcium oxides in stainless steel slag
To build in material, traditional stainless steel ground-slag does not pass through pre-treatment, and hydraulically active is low, growth over time, its gain in strength,
But unstability also strengthens therewith, the popularization and application of stainless steel slag have been had a strong impact on.
The content of the invention
It is this using stainless it is an object of the invention to provide a kind of method that environment-friendly baking-free bricks are made using stainless steel waste residue
Steel waste residue make environment-friendly baking-free bricks method can solve stainless steel slag be used for prepare stability caused during construction material compared with
The problem of poor.
In order to solve the above problems, the technical solution adopted by the present invention is：
This method that environment-friendly baking-free bricks are made using stainless steel waste residue is comprised the following steps：
A, stainless steel waste residue is soaked, is then crushed to particle diameter as 1 millimeter~5 millimeters；
B, be transferred to wet ball mill be milled to stainless steel waste residue particle diameter be 200 microns~600 microns, obtain slurry mix,
The slurry mix is delivered to shaking table and carries out isolated slag mortar；
C, vacuum filter filtering will be delivered to after the Steel-slag Sand pulp concentration, obtains the slag that water content is 15%~25%
Sand；
D, the Steel-slag Sand is transported to mixer, adds cement and water, batch mixing, shaped by fluid pressure, maintenance, stacking, then conserve；Steel
The mass ratio of slag sand, cement and water is 240：24：11.
In above-mentioned technical proposal, more specifically technical scheme can also be：The water content of stainless steel waste residue is less than 12%.
Further, the iron-holder of stainless steel waste residue is 3%~4%.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the present invention soaks stainless steel waste residue, can reduce stacking and follow-up broken caused dust, avoid dust to human body
Injury.
2nd, Steel-slag Sand prepared by the present invention, possesses the characteristic of clinker, and contain substantial amounts of SiO2, CaO and A12O3,
There is provided, the base substance condition of chemical change can occur rapidly, so as to break SiO in solid waste2, CaO and A12O3Vitreum be situated between it is steady
State, discharge active SiO2And A12O3Hydration reaction is carried out, generation has hydrated calcium silicate, the drated calcium aluminate of gelling,
There is enough strength and stabilities using the building block prepared by Steel-slag Sand of the present invention and cement, it is small normal concrete can be reached
Type building block standard GB/T/T8239-2014 requirement.
