Posachedwapa, mzere wopanga ufa wa chitsulo wokhala ndi mphamvu yayikulu kwambiri yopangira ku China wamalizidwa ndipo wayamba kugwira ntchito ku Shagang Group. Ndalama zonse zomwe zagwiritsidwa ntchito pa ntchitoyi ndi pafupifupi mayuan 170 miliyoni, ndipo akuti matani 600000 a ufa wa chitsulo adzapangidwa pachaka. Chifukwa cha kuuma kwa chitsulo, tinthu tating'onoting'ono ta mphero yachikhalidwe ndi mphero yozungulira tikadali pafupifupi 6-8mm mutaphwanya, zomwe zimafuna makampani opanga simenti kuti agwiritsenso ntchito.chitsulo chosungunukamphero yozungulira yoyimirira imagwiritsidwa ntchito pakupanga mphero yachitsulo ya Shagang, yomwe "imasiya" mwachindunji ulalo wapakati. Kusalala kwa mphero yachitsulo kumatha kufika pafupifupi 0.003mm. Potengera kuchepetsa kugwiritsa ntchito mphamvu kwa njirayi, imatha kuchepetsa zoopsa zachilengedwe, kuwonjezera phindu la chinthucho, kupititsa patsogolo kusintha kwa mphero yachitsulo kuchoka pa "zinyalala zolimba" kupita ku "zinthu", ndikukwaniritsa "kukweza kawiri" kwa ubwino woteteza chilengedwe komanso phindu lazachuma. Izi zikusonyeza kuti mphero yachitsulo ili ndi mwayi wabwino pamsika. Monga mphero yaukadaulo yozungulira yozungulira yozungulira yozungulira, HCMilling (Guilin Hongcheng) idzayambitsa kugwiritsa ntchito mphero yozungulira yozungulira yozungulira yozungulira yozungulira yozungulira.

chitsulo chopukusira slagmphero

Zikumveka kuti "kupukusira zitsulo" ndi pulojekiti yodziwika bwino yoteteza chilengedwe, pulojekiti yogwiritsidwanso ntchito pachuma, komanso "kudumpha kwachiwiri" kwa chithandizo cha zitsulo ku Shagang. Mu 2020, Shagang idzamanga pulojekiti yayikulu kwambiri yokonza zitsulo ku China ya matani 3.3 miliyoni, ndikukwaniritsa kugwiritsa ntchito 100% kwa zitsulo kudzera mu kulekanitsa maginito, kuphwanya, kupukuta ndodo, kuwunikira ndi kukonza kwina kozama. Kumapeto kwa Okutobala chaka chomwecho, pafupifupi matani 600 a zitsulo kuchokera ku Shagang adagwiritsidwa ntchito bwino pa projekiti yosinthira siponji ya misewu ya mzinda wa Zhangjiagang. Pambuyo pachitsulo chopukusira slagmpheroMzere wopangira wayamba kugwira ntchito, chitsulo chosungunuka chasinthadi kuchoka pa "zinyalala zolimba" kukhala "zinthu", ndipo zinthu zobwezeretsanso zinthu "zaumitsidwa ndi kufinyidwa", zomwe zakulitsa unyolo wobiriwira wazachuma. "M'mimba mwake mwa zipangizo zopangira ndi 6-8mm, kenako timaziperanso ndi chitsulo chosungunuka chozungulira chozungulira, ndipo kupyapyala kwake kumafika pafupifupi 0.003mm m'mimba mwake." Malinga ndi katswiri wochokera ku workshop yopukutira ya Shagang New Materials Co., mzere wopangidwa ndi chitsulo chosungunuka ndi pafupifupi matani 300000 mumakampani onse. Mzere wathu watsopano wopangidwa ndi matani 600000 ndi chizindikiro cha makampani onse ndipo umalimbikitsa kwambiri kupanga malamulo ogwira ntchito m'makampani.

Kafukufuku wokhudza kupanga ndi kugwiritsa ntchito ufa wa slag micro powder ndi nkhani yofunika kwambiri pambuyo pa kugwiritsidwa ntchito kwakukulu kwa ufa wa slag micro powder m'zaka zaposachedwa. Kupanga ufa wa micro powder kapena composite micro powder ndi slag yachitsulo kungathandize kuthetsa kusiyana kwa kugayidwa kwa simenti ya slag yachitsulo. Pamene slag yachitsulo yaphwanyidwa kukhala yopyapyala ndichitsulo chosungunuka mphero yozungulira yoyimirira, pamene malo enieniwo ali oposa 400m2Kg, chitsulo chachitsulo chingachotsedwe kwambiri. Kapangidwe ka kristalo ka zinthuzo kamakonzedwanso mwa kupukutira bwino kwambiri, ndipo mawonekedwe a tinthu tating'onoting'ono amasintha. Pamwamba pake pakhoza kukhala bwino ndikulimbikitsa ntchito ya slag yachitsulo, zomwe zimapangitsa kuti zinthu zomangira simenti zigwirizane bwino. Ufa wa slag yachitsulo ndi ufa wa slag zikaphatikizidwa, zimakhala ndi mwayi wokhala ndi malo ogwirira ntchito. Calcium hydroxide yomwe imapangidwa pamene C3S ndi C2S mu slag yachitsulo zimanyowa ndiye chinthu chachikulu chomwe chimayambitsa slag. Deta yaposachedwa ikuwonetsa kuti ngakhale kugwiritsa ntchito ufa wa slag ngati konkriti kungapangitse kuti konkriti ikhale yolimba komanso yogwira ntchito bwino, kuchepa kwa alkalinity ya blast furnace slag (% CaO+% MgO)/(% SiO2+% Al2O3), pafupifupi 0.9~1.2, kudzachepetsa kwambiri alkalinity ya gawo lamadzimadzi mu konkriti, kuwononga filimu yolimbitsa mu konkriti (pH<12.4 ndi yosavuta kuwononga), ndikuyambitsa dzimbiri la reinforcement mu konkriti. Kuphatikiza apo, blast furnace slag ndi thupi la vitreous lomwe C3AS ndi C2MS2 ndi zigawo zazikulu. Kutha kwa gellability ya granulated blast furnace slag powder kumachokera ku kusweka kwa kapangidwe ka slag vitreous. Zinthu zothira madzi zimatha kupangidwa pokhapokha ngati Ca (OH) 2 ikugwira ntchito. Slag yachitsulo ili ndi alkalinity yambiri (% CaO+% MgO)/(% SiO2), yomwe ndi pafupifupi 1.8~3.0. Michere makamaka ndi C3S, C2S, CF, C3RS2, RO, ndi zina zotero. FCaO ndi mchere wogwira ntchito mu slag yachitsulo zimapanga Ca (OH) 2 zikakumana ndi madzi, zomwe zimapangitsa kuti alkalinity yamadzimadzi ikhale bwino mu konkriti. Itha kugwiritsidwa ntchito ngati choyambitsa cha alkaline cha ufa wa slag. Konkriti wosakanikirana ndi ufa wa slag wachitsulo uli ndi mawonekedwe amphamvu kwambiri kumapeto kwa nthawi. Chifukwa chake, ufa wa slag wachitsulo ndi slag wophatikizika ukhoza kuphunzira kuchokera kwa wina ndi mnzake, ndipo magwiridwe antchito ake ndi abwino kwambiri.

Njira yopangira chitsulo chosungunuka mphero yozungulira yoyimirira Imaphatikizidwa ndi kuphwanya, kupukuta, kuumitsa ndi kusankha ufa, zomwe zimadziwika ndi kugwiritsa ntchito mphamvu zochepa, magwiridwe antchito abwino otsekera, malo ang'onoang'ono pansi, njira yosavuta, ndi zina zotero. Kusalala kofunikira ndi kugawa kwa tinthu tating'onoting'ono kungapezeke mwa kusintha liwiro lozungulira la chosungira ufa, kuchuluka kwa mpweya wa fan ya mphero ndi kupanikizika kopera. Ndi kusintha kwa njira zopangira ndi malingaliro komanso ukadaulo wokhwima kwambiri wa njira, ndalama zomwe zimagwiritsidwa ntchito pamakina opukutira ozungulira zimachepa kwambiri, zomwe zimakhala zofanana kapena zokwera pang'ono kuposa makina opukutira otsekedwa. Chifukwa cha zabwino zake pakugwira ntchito ndi kugwiritsa ntchito mphamvu, makinawa azigwiritsidwa ntchito kwambiri. HCMilling (Guilin Hongcheng) ndi mphero yaukadaulo yopukutira yozungulira yachitsulo.HLM zitsulo zotayidwamphero yozungulira yoyimirira ndi chida chabwino kwambiri chothandizira mphero yozungulira kuti ikule msika wa ufa wa slag wachitsulo. Imatha kupukusa ufa wa slag wachitsulo wokhala ndi malo apamwamba opitilira 700, kusunga njira ziwiri zopukusa ndi zomaliza, ndikumaliza kupanga ufa wa slag wachitsulo pang'onopang'ono.

Ngati muli ndi zofunikira zoyenera, chonde titumizireni uthenga kuti mudziwe zambiri za zidazo.
