1. Zomwe zikuchitika pakugwiritsa ntchito zida zachitsulo:

Steel slag ufa wakhala akuphatikizidwa mumtundu wa dziko monga kusakaniza simenti.Mayesero ambiri ofananitsa atsimikizira kuti: Pamene malo enieni a zitsulo za slag ufa ndi oposa 420m2 / kg, ntchito yake ndi yofanana ndi ya ng'anjo yamoto slag.The gulu kusanganikirana zitsulo slag ufa ndi slag ufa sangakhoze kuwonjezera patsogolo gawo la zitsulo slag ufa mu gulu ufa, komanso kuonjezera kuchuluka m'malo mwa gulu ufa kuti simenti pamaziko a kuonetsetsa ntchito ya konkire, kuti patsogolo kuchepetsa mtengo wokonzekera konkire.Zingathe mwachiwonekere kuchepetsa kuchepa kwa binder ndikusintha kukana kwa binder.Izi zikusonyeza kuti zitsulo slag ufa mankhwala ali ndi chiyembekezo chabwino msika.Pakalipano, kukhazikika kwa voliyumu ya slag yachitsulo kumachepetsedwa chifukwa cha kukhalapo kwa CaO ndi MgO yaulere.Kuchuluka kwa chitsulo okusayidi kumawonjezera kuvutika kwa kugaya, kugwiritsa ntchito mphamvu kwambiri kwa ufa wa tani wa slag, komanso kuvutikira kwa chitsulo cha slag ufa.Choncho, kuchuluka kwa malonda a msika wa zitsulo za slag ndi kochepa, zomwe zimapangitsanso kuti zitsulo za slag zikhale msika womwe ukubwera kuti upangidwe.

2. Kusakaniza konkire kumapereka malo ogwiritsira ntchito ultrafine zitsulo slag akupera:

Konkire centralized kusanganikirana ndi kusintha kwakukulu mu njira kupanga ntchito yomanga, ndi gawo la okonzeka osakaniza ntchito konkire chizindikiro mlingo wa kupanga mafakitale konkire mu dziko.Zochita zimasonyeza kuti kugwiritsa ntchito konkire wokonzeka kungapangitse ntchito zokolola zambiri kuposa kawiri, kupulumutsa simenti 10% ~ 15%, kuchepetsa ndalama za polojekitiyi pafupifupi 5%, ndikuonetsetsa kuti polojekitiyi ikhale yabwino, kupulumutsa malo omanga, kuchepetsa kuipitsidwa kwa fumbi, kuti kukwaniritsa zomangamanga zobiriwira.Kupanga konkriti yamalonda kumalimbikitsa kupanga ufa wa slag ndikukulitsa msika wofunikira wa ufa wa slag.Chomera chosakanikirana cha konkire cha China chinakhazikitsidwa m'ma 1980, poyamba ku Shanghai, Jiangsu ndi malo ena, chifukwa cha kukula kosalekeza kwa kukula kwa zomangamanga, makamaka chifukwa cha chitukuko chofulumira cha zomangamanga za mizinda ya kum'mwera chakum'mawa, kuphatikizapo mndandanda wa ndondomeko zothandizira ndi njira zotengedwa ndi akuluakulu a zomangamanga, kotero kuti konkire yosakaniza ya mzindawu ikuwonjezeka ndi 15% pachaka.Chifukwa mtengo wa slag ndi chitsulo slag ndi wotsika kuposa simenti, konkire wothira slag ndi zitsulo slag ndi ndalama ndi oyenera ntchito intensively osakaniza malonda konkire.Konkire yopangidwa ndi kusakaniza slag ndi chitsulo slag ndi simenti, miyala ndi mchenga wachikasu uli ndi ubwino wa mphamvu yochedwa kwambiri, kutentha kwapansi kwa hydration, kukana kuvala bwino ndi mphamvu yogwirizana kwambiri ndi zitsulo zachitsulo.Ndizoyenera makamaka ku nyumba zapamwamba, ma DAMS, ma eyapoti, maziko akulu akulu ndi ntchito zapansi pamadzi.Pakalipano, konkire yamphamvu kwambiri imakonzedwa ndi kusakaniza phulusa la silika ndi kuchepetsa kuchepetsa madzi, koma kusowa kwa silika phulusa zopangira ndi kuchepetsa kuchepetsa madzi kumakhala okwera mtengo, zomwe zimapangitsa kuti pakhale kukwera mtengo kwa konkire.Ndi zofunikira zapamwamba komanso zapamwamba zamakhalidwe a konkire m'mapulojekiti akuluakulu apadera, kufunikira kowonjezereka kwa konkire yamalonda kwatsegula msika waukulu wogwiritsa ntchito kwambiri slag ndi chitsulo slag ufa.Kumvetsetsa kwa anthu za makhalidwe a slag ndi zitsulo za slag ufa, nyumba yatsopano yomangira, ikukulanso.Ndi Kukwezeleza ndi kugwiritsa ntchito konkire malonda m'dzikoli ndi kukhazikitsa mfundo dziko zokhudzana slag ndi zitsulo slag ufa mankhwala, ndi kukhazikitsa ndondomeko monga kuletsa mosamalitsa kusakaniza konkire pa malo omanga m'mizinda, msika wa slag ndi zitsulo. ufa wa slag udzakhala waukulu kwambiri, ndipo kugwiritsidwa ntchito kwake kudzakopa chidwi kwambiri.

3. njira yokonzekera ndi zida za chitsulo cha slag yaying'ono-ufa ofukula akupera atchuka ndikugwiritsidwa ntchito.

Pakali pano, ukadaulo wopukutira wowongoka umagwiritsidwa ntchito pogaya chitsulo cha slag yaying'ono-ufa ndikupanga zinthu zomwe zimalowa m'malo mwa clinker yamphamvu ya simenti, yomwe ndi yaukadaulo wapamwamba wopanga mafakitale.M'mbuyomu, kawirikawiri slag, zitsulo slag ndi simenti clinker, gypsum, etc. pamodzi, malinga ndi gawo lina la akupera mu akupera kupanga simenti.Chifukwa cha kusauka kwa slag ndi zitsulo zachitsulo, kugaya sikungapangidwe bwino kwambiri pamene kusakanikirana ndi clinker ya simenti, ntchito zake sizingakwaniritsidwe bwino, ndipo kuchuluka kwake ndi kugwiritsa ntchito slag ndi chitsulo kumakhala kochepa pamlingo wina.Pokonzekera ufa wa ultrafine kuchokera kuzitsulo zachitsulo zokha, Jiangsu iron ndi mabizinesi achitsulo ali patsogolo.Mabizinesi angapo achitsulo oimiridwa ndi Changzhou Zhongtian Iron ndi Steel apanga mizere yapadera yachitsulo ya slag ofukula yopera.Monga wopanga zitsulo zaufa waufa woyimirira, HCM Machinery imapereka chithandizo chaukadaulo munjira yopera zitsulo za ultrafine komanso kupanga zida zazikulu zowongoka.makhalidwe ake luso makamaka mbali zotsatirazi: kusankha ofukula mphero akupera zitsulo slag ufa, ndi luso patsogolo, kupanga odalirika, makhalidwe apamwamba ntchito zokolola, ndi ofukula mphero kubala tani yeniyeni padziko dera 400m2/kg ~ 500m2/kg. slag, zitsulo slag ufa, kuposa chikhalidwe mpira mphero kupanga zolemera chomwecho ufa kupulumutsa magetsi 30% ~ 50%;Ufa wabwino wa slag ndi zitsulo zachitsulo umasakanizidwa mwachindunji mu konkire, zomwe zimasunga kuchuluka kwa simenti ndipo motero zimapulumutsa mphamvu yogwiritsira ntchito simenti.Slag, chitsulo slag akupera ndondomeko, akhoza flexible kusintha fineness mankhwala malinga ndi zosowa msika.Ndi kuwonjezeka kwa kuwonjezera kwa slag ndi chitsulo slag mu konkire, kutentha kwa hydration ndi zomwe zili ndi zigawo zovulaza za konkriti zimatha kuchepetsedwa, zomwe zimapanga mikhalidwe yabwino yopititsira patsogolo ntchito ya konkire ndi kugwiritsira ntchito mphamvu zochepa.Silagi yachitsulo imapukutidwa ndi ufa wogaya woyima, ndipo zinthuzo zimasiyidwa pamalo achinyontho pa kutentha kwakukulu (100 ℃ ~ 300 ℃).Ambiri mwa calcium oxide yaulere ndi magnesium oxide yaulere mu chitsulo cha slag yaying'ono-ufa amathiridwa mu calcium hydroxide yogwira kwambiri ndi magnesium hydroxide.Kuonjezera apo, chifukwa cha kuphatikizika kwa slag ndi zitsulo zachitsulo mu konkire, zomwe alkali aggregate zimatha kuchepetsedwa bwino, ming'alu ya konkire imatha kupewedwa, ndipo moyo wa nyumba ukhoza kuwonjezeredwa.Choncho, konkire yosakanikirana ndi ufa wa slag imalandiridwa ndi makampani omangamanga chifukwa cha katundu wake wapadera.Akupera zitsulo slag yekha angagwiritsidwe ntchito ngati mankhwala kwa kupanga konkire ndi kusanganikirana malinga ndi zosowa msika, komanso akhoza kusintha malinga ndi kufunika kusintha fineness ndi kusakaniza kuchuluka kukhazikitsidwa mu simenti zogulitsa.

Iron and steel enterprises can take advantage of the existing regional location of steel mills, and the source of raw materials is fully guaranteed; The steel mill has advanced and strict scientific management experience, and has experienced technical team and staff team, which provides the guarantee of organization, technology and production management for the implementation of the project and market development; Steel plant power supply, water supply source reliable, convenient transportation, good cooperation conditions, construction conditions are very superior. To sum up, the construction of steel slag micro-powder projects in iron and steel enterprises can not only turn waste into treasure, improve the added value of steel making, create considerable economic benefits for iron and steel enterprises, but also protect the environment, in line with the policy direction of steel and cement industry structural adjustment. The development of steel enterprises layout steel slag powder project is a good thing to benefit the country and the people, has a broad future and is of great significance, and will play a positive role in promoting the construction of "waste free city" and promoting the sustainable development of the steel industry.
