Abstract
Make the method that adhesive is fine ore cold-press agglomeration using environmentally friendly ash the invention discloses a kind of, be agglomeration of fine ore by the grey peripheral adhesive of environmental protection, environmental benefit is perfect, and obtained lump ore technical-economic index is excellent.The method for producing mineral wool using environmental-protecting dust powder and molten slag, the waste discharge process that can become including environmentally friendly ash realize energy-saving and emission-reduction into resource reutilization process.Dust is flown upward on the stove that the present invention is received using in silicochromium mineral hot furnace production process and carries out cold-press agglomeration as fine ore as adhesive; obtained spherical lump ore is used directly for producing high carbon ferro-chrome; this reluctant production waste material of environmentally friendly ash is set to change one's identity suddenly the raw material become as enterprise's extra earning; solves the problems, such as environmentally friendly dust heap product in factory; also enterprise is allowed positively to go to handle, consume environmentally friendly ash; the situation that there are environmental protection facility in indivedual enterprises and are not turned on is prevented, final maximum biggest beneficiary is blue sky and white cloud.
Description
Technical field
The present invention relates to fine ore cold-press agglomeration technical field, it particularly relates to which a kind of be as adhesive using environmentally friendly ash
The method of fine ore cold-press agglomeration.
Background technology
With the issuing and implementation of national every environmentally friendly pressure standard, the recovery of stove dirt turns into produces in the industry silicon chromium
" standard configuration ", but so far there is not yet the effective way that this dust utilizes.Manufacturer is entered using pocket type dust exhaust apparatus to stove dirt more
Row collect, be accumulated to it is a certain amount of after uniformly handled again, sometimes even can be accumulated to hundreds of tons, take a large amount of places, and this
Kind of dust in atmosphere can slowly moisture absorption it is hardened, activity reduces, and discharges pernicious gas.Under this background, enterprise is passively
Substantial amounts of financial resource and material resource are spent to solve these stove dirt, cause many producers even if the situation for possessing environmental protection facility and being also not turned on.
These stove dirt how are preferably recycled, make enterprise is dynamic to go active process, are people in the art
The important research direction of member.
The problem of in correlation technique, effective solution is not yet proposed at present.
The content of the invention
For the above-mentioned technical problem in correlation technique, it is that fine ore is cold that the present invention, which proposes that one kind makees adhesive using environmentally friendly ash,
The method for pressing agglomeration, it is agglomeration of fine ore, environmental benefit is perfect, and obtained lump ore Technological Economy refers to using environmentally friendly ash as adhesive
Mark excellent.
To realize above-mentioned technical purpose, the technical proposal of the invention is realized in this way：
It is a kind of to make the method that adhesive is fine ore cold-press agglomeration using environmentally friendly ash, comprise the following steps：To environmentally friendly ash and fine chrome mine
In plus water stir and evenly mix, suppress balling-up, dry after obtain lump ore, the environmentally friendly ash is institute in silicochromium mineral hot furnace production process
Dust is flown upward on the stove received.
Further, the mass ratio of the environmental protection ash and fine chrome mine is 1:2.
Further, amount of water is the environmental protection ash and the 2% ~ 3% of fine chrome mine gross mass.Water content is big, and ball is shaky, firmly
Change slow；The small then difficult shaping of water content.
Further, the balling-up is shaped as oblate spheroid, a diameter of 54mm of balling-up, thickness 30mm.
Further, balling-up, pressure 500kg/cm are suppressed using roller press2。
Further, mixing time is not less than 15 minutes.Stirring is abundant, generally 17 minutes.Not less than 15 minutes.It is general
Logical build concrete mixer.
Another aspect of the present invention, there is provided a kind of lump ore for making adhesive using environmentally friendly ash, it is by above method system
.
Beneficial effects of the present invention：The present invention on the stove received in silicochromium mineral hot furnace production process to fly upward dust
It is that fine ore carries out cold-press agglomeration as adhesive, obtained spherical lump ore is used directly for producing high carbon ferro-chrome, makes environmentally friendly ash
This reluctant production waste material is changed one's identity suddenly the raw material become as enterprise's extra earning, solves environmentally friendly dust heap product in factory
Problem, enterprise is also allowed positively to go to handle, consume environmentally friendly ash, having prevented indivedual enterprises has environmental protection facility and be not turned on
Situation, final maximum biggest beneficiary is blue sky and white cloud.
The grey pressure ball of environmental protection, solve the problems, such as the recycling for reclaiming dust first, improve Cr2O3 And SiO2Utilization
Rate, secondly, enterprise's ore deposit structure is changed, improves fine ore portion, at present, the lump ore of the same grade of in the market is than powder
Expensive 300 ~ 400 yuan/ton of ore deposit, and after using method of the present invention, enterprise can buy fine ore and voluntarily manufacture lump ore, except setting
Expenditure on received shipment row does not have other costs substantially, further reduces production cost.The environmental requirement of hardness, becomes
Golden channel is inhaled by enterprise true.So as to prevent the situation that there are environmental protection facility in indivedual enterprises and are not turned on.It is of the present invention
If method must promote, greatest benefit side is blue sky and white cloud.
