Abstract
A kind of Technology of Steel Slag Processing belongs to pneumatic steelmaking Technologies of Steel Slag Treatment field.Vessel slag is from bored slag bath through cooling of fetching water, decomposition technique processing, the slag of granularity ＜ 250mm uses jaw crusher by slag crushing to ＜ 70mm, it is slagged tap steel using across belt magnetic separator separation, hydro cone-crusher is reused by slag crushing to ＜ 10mm, is slagged tap steel using across belt magnetic separator separation；Most at last slag processing into ＜ 10mm, the tailings of slag steel content ＜ 2%.The advantage is that device layout arranges that in a manner that ring-like arrangement is combined compact in design, floor space is small, small investment, and slag processing is efficient using system vertical.
Description
Technical field
The invention belongs to pneumatic steelmaking Technologies of Steel Slag Treatment field, more particularly to a kind of Technology of Steel Slag Processing.More particularly to
A kind of compact Technology of Steel Slag Processing.
Background technology
As steel and iron industry is fast-developing, steel-making new technology constantly puts into the requirement of application and social development to environmental protection
It increasingly improves, slag processing is gradually paid attention to be subject to steel producer, and generally newly-built steel mill just takes into full account slag at the beginning of design
The factors such as disposal field arrangement, lectotype selection, slag processing system layout tend to be reasonable, and operation is efficiently smooth, disclosure satisfy that steel
The daily production operating of factory, the requirement that slag recycles；But for the old factory for long history of partly founding the factory, slag processing is general
The simple process for treating steel slag such as method, Re Fa methods are abandoned using cold, lack post-production, screening, the advanced hand recycled
Section, causes production run, environmental protection different degrees of influence.
The content of the invention
It is an object of the invention to provide a kind of Technology of Steel Slag Processing, solve that slag processing land area is larger to ask
Topic.Suitable for site area it is limited or to original simple steel slag disposal system carry out technique upgrading；
A kind of Technology of Steel Slag Processing, specific steps and parameter are as follows：
1st, vessel slag pours into shaking for 250mm × 250mm apertures from bored slag bath after cooling of fetching water, decomposition technique have been handled
On dynamic diagrid 2, the slag of granularity ＜ 250mm enters underground material storehouse 3, is persistently given by the electro-vibrating feeder under raw material cabin 3
After belted electronic balance metering, via ribbon conveyer 5, slag after-treatment region 6 is transported to by underground vestibule for material.
2nd, after slag enters after-treatment region 6, the slag steel of ＜ 250mm, the steel after magnetic separation are magneticly elected across belt magnetic separator
Slag is sent to 70 × 70mm vibrating bars grizzly 2, and the slag of ＞ 70mm enters the steel that jaw crusher is broken into ＜ 70mm through chute on sieve
Slag.
3rd, the slag steel of ＜ 70mm is magneticly elected across belt magnetic separator, the slag after magnetic separation is sent to 10 × 10mm vibrating bars grizzly 2, grain
The slag of footpath ＞ 10mm enters hydro cone-crusher through feed bin-electro-vibrating feeder, the slag of ＜ 10mm is broken into, across band
Formula magnet separator magnetic selects the slag steel of ＜ 10mm, and the slag of ＜ 10mm is transported to finishing room via ribbon conveyer.
Most at last slag processing into grain size ＜ 10mm, the tailings of slag steel content ＜ 2wt%.
It is an advantage of the current invention that equipment arrangement arranges in a manner that ring-like arrangement is combined have using system vertical
The characteristics of compact in design, floor space is small, small investment, slag processing is efficient.
Description of the drawings
Fig. 1 arranges schematic diagram for present device.Wherein, steel slag hot disintegrating region 1, vibrating bar grizzly 2, raw material cabin 3, plant area road
Road 4, ribbon conveyer 5, slag after-treatment region 6.
Fig. 2 is present invention process flow diagram.
Specific embodiment
Vessel slag after cooling of fetching water, decomposition technique have been handled, pours into the diagrid in 250mm × 250mm apertures from bored slag bath
On, the slag of granularity ＜ 250mm enters underground material storehouse, is persistently fed by the electro-vibrating feeder under raw material cabin, electronics skin
After belt scale metering, via ribbon conveyer, slag after-treatment region is transported to by underground vestibule.
After slag enters after-treatment region, the slag steel of ＜ 250mm is magneticly elected across belt magnetic separator, the slag after magnetic separation is sent
Toward 70 × 70mm vibrating bars grizzly, the slag of ＞ 70mm enters the slag that jaw crusher is broken into ＜ 70mm through chute on sieve.
The slag steel of ＜ 70mm is magneticly elected across belt magnetic separator, the slag after magnetic separation is sent to 10 × 10mm vibrating bars grizzly, ＞
The slag of 10mm enters hydro cone-crusher through feed bin-electro-vibrating feeder, is broken into the slag of ＜ 10mm, across belt magnetic
Machine is selected to magneticly elect the slag steel of ＜ 10mm, the slag of ＜ 10mm is transported to finishing room via ribbon conveyer.
