1. Momwe chuma chikuyendera pakali pano:

Ufa wa slag wachitsulo wakhala ukuphatikizidwa mu muyezo wa dziko lonse ngati chisakanizo cha simenti. Mayeso ambiri oyerekeza atsimikizira kuti: Pamene malo enieni a ufa wa slag wachitsulo ndi opitirira 420m2/kg, ntchito yake imakhala yofanana ndi ya slag ya ng'anjo yophulika. Kusakaniza kophatikizana kwa ufa wa slag wachitsulo ndi ufa wa slag sikungowonjezera kuchuluka kwa ufa wa slag wachitsulo mu ufa wophatikizana, komanso kumawonjezera kuchuluka kwa ufa wophatikizana ndi simenti potengera momwe konkriti imagwirira ntchito, kuti kuchepetse mtengo wokonzekera konkriti. Zingathe kuchepetsa kuchepa kwa chogwirira ntchito ndikuwonjezera kukana kwa chogwirira ntchito. Izi zikusonyeza kuti zinthu zopangidwa ndi ufa wa slag wachitsulo zili ndi chiyembekezo chabwino pamsika. Pakadali pano, kukhazikika kwa voliyumu ya slag yachitsulo kumachepa chifukwa cha kukhalapo kwa CaO ndi MgO yaulere. Kuchuluka kwa iron oxide kumawonjezera zovuta zopera, kugwiritsa ntchito mphamvu zambiri kwa ufa wa ton slag, komanso kuvutika kokonza ufa wa slag wachitsulo. Chifukwa chake, kuchuluka kwa malonda a msika wa ufa wa chitsulo ndi kochepa, zomwe zimapangitsanso kuti ufa wa chitsulo ukhale msika watsopano woti upangidwe.

2. Kusakaniza konkriti kumapereka malo ogwiritsira ntchito kugaya chitsulo cha ultrafine slag:

Kusakaniza konkire pakati pa konkire ndi kusintha kwakukulu pakupanga mapulojekiti omanga, ndipo kuchuluka kwa ntchito za konkire yosakanikirana bwino kumawonetsa kuchuluka kwa kupanga konkire m'mafakitale mdzikolo. Machitidwe akuwonetsa kuti kugwiritsa ntchito konkire yosakanikirana bwino kumatha kuwonjezera zokolola za antchito kuwirikiza kawiri, kusunga simenti ndi 10% mpaka 15%, kuchepetsa ndalama za polojekiti pafupifupi 5%, komanso kungathandize kuonetsetsa kuti ntchitoyo ndi yabwino, kusunga malo omanga, kuchepetsa kuipitsa fumbi, kuti pakhale zomangamanga zobiriwira. Kupanga konkire yogulitsa kumalimbikitsa chitukuko cha kupanga ufa wa slag ndikukulitsa msika wofunikira wa ufa wa slag. Chomera chosakaniza konkire chosakanikirana bwino ku China chidakhazikitsidwa m'ma 1980, poyamba ku Shanghai, Jiangsu ndi malo ena, chifukwa cha kukula kosalekeza kwa kukula kwa ntchito yomanga, makamaka chifukwa cha kukula kwachangu kwa ntchito yomanga mizinda ya kum'mwera chakum'mawa kwa nyanja, limodzi ndi mfundo zingapo zothandizira ndi njira zomwe akuluakulu omanga adatenga, kotero kuti konkire yosakanikirana bwino ya mzindawu imawonjezeka ndi 15% pachaka. Popeza mtengo wa slag ndi chitsulo ndi wotsika kuposa wa simenti, konkire wosakaniza ndi slag ndi chitsulo ndi wotsika mtengo ndipo uyenera kugwiritsidwa ntchito mu konkire yogulitsa yosakanikirana kwambiri. Konkire yopangidwa posakaniza slag ndi chitsulo ndi simenti, miyala ndi mchenga wachikasu ili ndi ubwino wa mphamvu yayitali yochedwa, kutentha kochepa, kukana kuwonongeka bwino komanso mphamvu yayikulu yolumikizana ndi zitsulo. Ndi yoyenera makamaka nyumba zazitali, madamu, ma eyapoti, maziko akulu akuya komanso mapulojekiti apansi pamadzi. Pakadali pano, konkire yamphamvu kwambiri imakonzedwa makamaka posakaniza phulusa la silica ndi chochepetsera madzi chogwira ntchito bwino, koma kusowa kwa zipangizo zopangira phulusa la silica ndi chochepetsera madzi chogwira ntchito bwino kwambiri ndi okwera mtengo, zomwe zimapangitsa kuti konkire ikhale yokwera mtengo. Chifukwa cha zofunikira zapamwamba komanso zapamwamba za makhalidwe a konkire m'mapulojekiti akuluakulu apadera, kufunikira kowonjezereka kwa konkire yamalonda kwatsegula msika waukulu wogwiritsa ntchito kwambiri ufa wa slag ndi chitsulo. Kumvetsetsa kwa anthu za makhalidwe a ufa wa slag ndi chitsulo, zipangizo zatsopano zomangira, kukukulirakuliranso. Ndi kukwezedwa ndi kugwiritsidwa ntchito kwa konkriti yogulitsa m'dziko muno komanso kukhazikitsidwa kwa miyezo ya dziko lonse yokhudzana ndi zinthu zopangidwa ndi ufa wa slag ndi chitsulo, komanso kukhazikitsidwa kwa mfundo monga kuletsa konkriti kusakaniza m'malo omanga m'mizinda, msika wa ufa wa slag ndi chitsulo udzakhala waukulu kwambiri, ndipo kugwiritsidwa ntchito kwake kudzakopa chidwi cha anthu ambiri.

3. njira yokonzekera ndi zida zopukutira zitsulo za slag micro-ufa wowongoka zatchuka ndikugwiritsidwa ntchito

Pakadali pano, ukadaulo wopukutira wowongoka umagwiritsidwa ntchito popukutira ufa wachitsulo wa slag micro-ufa ndikupanga zinthu zomwe zimalowa m'malo mwa clinker ya simenti yamphamvu kwambiri, yomwe ndi yaukadaulo wapamwamba wopanga mumakampani. Kale, nthawi zambiri slag, slag yachitsulo ndi clinker ya simenti, gypsum, ndi zina zotero pamodzi, malinga ndi kuchuluka kwa kupukutira mu kupanga simenti. Chifukwa cha kusagwira bwino kwa slag ndi slag yachitsulo, kupukutira sikungaphwanyidwe bwino kwambiri mukasakaniza ndi clinker ya simenti, magwiridwe ake sangapangidwe mokwanira, ndipo kuchuluka ndi kugwiritsa ntchito kwa slag ndi slag yachitsulo ndizochepa pamlingo winawake. Pokonzekera ufa wa ultrafine kuchokera ku slag yachitsulo yokha, makampani achitsulo ndi zitsulo a Jiangsu ali patsogolo. Makampani angapo achitsulo omwe akuyimiridwa ndi Changzhou Zhongtian Iron and Steel apanga mizere yapadera yopangira njira yopukutira yowongoka yachitsulo. Monga wopanga chitsulo cha slag micro-ufa wowongoka, HCM Machinery imapereka chithandizo chaukadaulo mu njira yopukutira yowongoka yachitsulo cha ultrafine komanso kupanga zida zazikulu zopukutira zowongoka. Makhalidwe ake aukadaulo makamaka ndi awa: kusankha ufa wopukutira zitsulo woyimirira, wokhala ndi ukadaulo wapamwamba, kupanga kodalirika, magwiridwe antchito apamwamba, wokhala ndi mtunda woyimirira kuti apange tani ya malo enieni a 400m2/kg ~ 500m2/kg slag, ufa wa slag wachitsulo, kuposa kupanga kwachikhalidwe kwa mphero ya mpira wolemera womwewo wa ufa wosunga magetsi 30% ~ 50%; Ufa wabwino wa slag ndi slag wachitsulo umasakanizidwa mwachindunji mu konkriti, zomwe zimasunga kuchuluka kwa simenti motero zimasunga mphamvu yogwiritsira ntchito simenti. Slag, njira yopukutira zitsulo, imatha kusintha mosavuta kusalala kwa zinthu malinga ndi zosowa zamsika. Ndi kuwonjezeka kwa kuwonjezera slag ndi slag yachitsulo mu konkriti, kutentha kwa madzi ndi kuchuluka kwa zigawo zovulaza za konkriti kumatha kuchepetsedwa, zomwe zimapangitsa kuti zinthu zikhale bwino kuti konkriti igwire bwino ntchito ndi mphamvu zochepa. Slag yachitsulo imaphwanyidwa ndi ufa wopukutira woyimirira, ndipo zinthuzo zimaphwanyidwa pamalo onyowa pa kutentha kwakukulu (100℃ ~ 300℃). Kalisiyumu oxide wambiri waulere ndi magnesium oxide waulere mu ufa wa chitsulo umasungunuka kukhala calcium hydroxide yogwira ntchito kwambiri ndi magnesium hydroxide. Kuphatikiza apo, chifukwa cha slag ndi slag yachitsulo zomwe zimapezeka mu konkire, mphamvu ya alkali aggregate imatha kuchepetsedwa bwino, ming'alu yaying'ono ya konkire ikhoza kupewedwa, ndipo moyo wa nyumba ukhoza kukulitsidwa. Chifukwa chake, konkire wosakanikirana ndi ufa wa slag umalandiridwa ndi makampani omanga chifukwa cha mawonekedwe ake apadera. Kupera slag yachitsulo yokha kungagwiritsidwe ntchito ngati chinthu chopangira konkire ndikusakaniza malinga ndi zosowa za msika, ndipo kungasinthidwenso malinga ndi kufunika kosintha kusalala ndi kuchuluka kosakaniza komwe kumapangidwira kukhala simenti yogulitsa.

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.
