1. Imeko yangoku yokusetyenziswa kwezixhobo ze-slag yentsimbi:

Umgubo we-slag wentsimbi sele ubandakanyiwe kumgangatho wesizwe njengomxube wesamente. Inani elikhulu lovavanyo lokuthelekisa luye lwabonisa ukuba: Xa indawo ethile yomphezulu womgubo we-slag wentsimbi ingaphezulu kwe-420m2/kg, umsebenzi wayo ufana nowe-blast furnace slag. Ukuxuba okudibeneyo komgubo we-slag wentsimbi kunye nomgubo we-slag akunakuphucula kuphela umlinganiselo womgubo we-slag wentsimbi kwi-composite powder, kodwa kunokunyusa ubungakanani bokutshintshwa komgubo we-composite kwi-samente ngokusekelwe ekuqinisekiseni ukusebenza kwekhonkrithi, ukuze kuncitshiswe ngakumbi iindleko zokulungiselela ikhonkrithi. Kunokunciphisa ngokucacileyo ukuguquguquka kokuncipha kwe-binder kunye nokuphucula ukumelana nokuqhekeka kwe-binder. Oku kubonisa ukuba iimveliso zomgubo we-slag wentsimbi zinethuba elihle lemarike. Okwangoku, ukuzinza komthamo we-slag yentsimbi kuyancipha ngenxa yokubakho kwe-CaO kunye ne-MgO ekhululekileyo. Umxholo ophezulu we-iron oxide unyusa ubunzima bokugaya, ukusetyenziswa kwamandla aphezulu komgubo we-ton slag, kunye nobunzima bokucubungula umgubo we-slag wentsimbi. Ke ngoko, umthamo wentengiso yemarike yepowder ye-slag yentsimbi incinci, nto leyo eyenza ukuba ipowder ye-slag yentsimbi ibe yimarike esakhulayo eza kuphuhliswa.

2. Ukuxuba ikhonkrithi kunika indawo yokusetyenziswa kwe-ultrafine steel slag grinding:

Ukuxuba ikhonkrithi exutyiweyo yinguqu enkulu kwindlela yokuvelisa iiprojekthi zokwakha, kwaye umlinganiselo wokusetyenziswa kwekhonkrithi exutyiweyo uphawula umgangatho wemveliso yemizi-mveliso yekhonkrithi kweli lizwe. Indlela yokusebenza ibonisa ukuba ukusetyenziswa kwekhonkrithi exutyiweyo kunokunyusa imveliso yabasebenzi ngokuphindwe kabini, konge isamente nge-10% ukuya kwi-15%, kunciphise iindleko zeprojekthi malunga ne-5%, kwaye kunokuqinisekisa umgangatho weprojekthi, konge umhlaba wokwakha, kunciphise ungcoliseko lothuli, ukuze kufezekiswe ulwakhiwo oluluhlaza. Uphuhliso lwekhonkrithi yorhwebo lukhuthaza uphuhliso lwemveliso yepowder yeslag kwaye lwandisa imarike yemfuno yepowder yeslag. Isityalo sokuxuba ikhonkrithi exutyiweyo yaseTshayina sasekwa ngeminyaka yoo-1980, ekuqaleni eShanghai, eJiangsu nakwezinye iindawo, ngenxa yokwanda okuqhubekayo kobukhulu bolwakhiwo, ngakumbi ngenxa yophuhliso olukhawulezileyo lokwakhiwa kwezixeko ezikunxweme olusemzantsi-mpuma, kunye nothotho lwemigaqo-nkqubo exhasayo kunye namanyathelo athathwe ngabasemagunyeni bokwakha, ukuze ikhonkrithi exutyiweyo yesixeko inyuke nge-15% ngonyaka. Ngenxa yokuba ixabiso le-slag kunye ne-steel slag liphantsi kunelesamente, ikhonkrithi exutywe ne-slag kunye ne-steel slag ingabizi kwaye ifanelekile ukusetyenziswa kwikhonkrithi yorhwebo exutywe kakhulu. Ikhonkrithi eyenziwe ngokuxuba i-slag kunye ne-steel slag kunye nesamente, ilitye kunye nesanti etyheli ineenzuzo zokuba namandla aphezulu emva kwexesha, ubushushu obuphantsi bokufuma, ukumelana nokuguguleka okuhle kunye namandla aphezulu okubopha kunye neebha zentsimbi. Ifanelekile ngokukodwa kwizakhiwo eziphakamileyo, ii-DAMS, izikhululo zeenqwelo-moya, iziseko ezinkulu ezinzulu kunye neeprojekthi zamanzi angaphantsi kwamanzi. Okwangoku, ikhonkrithi enamandla kakhulu ilungiswa ikakhulu ngokuxuba uthuthu lwe-silica kunye ne-arhente yokunciphisa amanzi esebenza kakuhle, kodwa ukungabikho kwezixhobo eziluhlaza ze-silica ash kunye ne-arhente yokunciphisa amanzi esebenza kakuhle kuyabiza, nto leyo ebangela ixabiso eliphezulu lekhonkrithi. Ngenxa yeemfuno eziphezulu neziphezulu zeempawu zekhonkrithi kwiiprojekthi ezikhethekileyo ezinkulu, imfuno ekhulayo yekhonkrithi yorhwebo ivule imakethi ebanzi yokusetyenziswa kakhulu kwe-slag kunye ne-steel slag powder. Ukuqonda kwabantu iimpawu ze-slag kunye ne-steel slag powder, izinto zokwakha ezintsha, nako kuya kusiba nzulu. Ngokukhuthazwa nokusetyenziswa kwekhonkrithi yorhwebo kweli lizwe kunye nokuphunyezwa kwemigangatho yesizwe enxulumene neemveliso ze-slag kunye ne-steel slag powder, kunye nokuphunyezwa kwemigaqo-nkqubo efana nokuthintela ngokungqongqo ukuxuba ikhonkrithi kwiindawo zokwakha kwiindawo zasezidolophini, imakethi ye-slag kunye ne-steel slag powder iya kuba nkulu ngakumbi, kwaye ukusetyenziswa kwayo kuya kutsala ingqalelo ngakumbi nangakumbi.

3. Inkqubo yokulungiselela kunye nezixhobo zokugaya ngokuthe nkqo zentsimbi ye-slag micro-powder ziye zathandwa kwaye zasetyenziswa

Okwangoku, iteknoloji yokugaya ngokuthe nkqo isetyenziselwa ukugaya i-metal slag micro-powder kunye nokuvelisa iimveliso ezithatha indawo ye-cement clinker enamandla aphezulu, eyiyeyona teknoloji iphambili yemveliso kushishino. Ngaphambili, ngokuqhelekileyo i-slag, i-steel slag kunye ne-cement clinker, i-gypsum, njl.njl. kunye, ngokwenxalenye ethile yokugaya ekuveliseni isamente yokugaya. Ngenxa yokungalungelani kakuhle kwe-slag kunye ne-steel slag, ukugaya akunakugaywa kakuhle xa kuxutywe ne-cement clinker, ukusebenza kwayo akunakuphuhliswa ngokupheleleyo, kwaye ubungakanani kunye nokusetyenziswa kwe-slag kunye ne-steel slag kunqunyelwe kwinqanaba elithile. Ekulungiseleleni umgubo we-ultrafine ovela kwi-steel slag yodwa, amashishini esinyithi kunye nentsimbi aseJiangsu aphambili. Amashishini aliqela esinyithi amelwe yiChangzhou Zhongtian Iron and Steel akhe imigca ekhethekileyo yemveliso ye-steel slag vertical process. Njengomvelisi we-steel slag micro-powder vertical mill, i-HCM Machinery inika inkxaso yobugcisa kwindlela yenkqubo yokugaya i-steel slag ultrafine kunye nokuveliswa kwezixhobo eziphambili ze-vertical mill. Iimpawu zayo zobugcisa zezi zilandelayo: ukukhethwa komgubo we-slag wentsimbi osikiweyo ngokuthe nkqo, onobuchwepheshe obuphambili, imveliso ethembekileyo, iimpawu zemveliso ephezulu yabasebenzi, kunye nomatshini osikiweyo ngokuthe nkqo ukuvelisa itoni yendawo ethile yomphezulu we-400m2/kg ~ 500m2/kg, umgubo we-slag wentsimbi, kunemveliso ye-ball mill yendabuko enobunzima obufanayo bokugcina umbane nge-30% ~ 50%; Umgubo ocolekileyo we-slag kunye ne-slag yentsimbi uxutywa ngqo kwikhonkrithi, nto leyo egcina ubungakanani besamente kwaye ngaloo ndlela igcina ukusetyenziswa kwamandla kwemveliso yesamente. I-Slag, inkqubo yokugaya i-slag yentsimbi, inokulungisa ngokulula ubuncinci beemveliso ngokweemfuno zemarike. Ngokwanda kokongeza i-slag kunye ne-slag yentsimbi kwikhonkrithi, ubushushu bokufuma kunye nomxholo wezinto ezinobungozi zekhonkrithi kunokuncipha, nto leyo edala iimeko ezilungileyo zokuphucula ukusebenza kwekhonkrithi ngokusetyenziswa kwamandla okuphantsi. I-slag yentsimbi igutywa ngumgubo wokugaya othe nkqo, kwaye izinto zigutywa kwindawo efumileyo kubushushu obuphezulu (100℃ ~ 300℃). Uninzi lwe-calcium oxide ekhululekileyo kunye ne-magnesium oxide ekhululekileyo kwi-micro-powder ye-steel slag zifakwa kwi-calcium hydroxide esebenzayo kakhulu kunye ne-magnesium hydroxide. Ukongeza, ngenxa yokufakwa kwe-slag kunye ne-steel slag kwikhonkrithi, ukusabela kwe-alkali aggregate kunokunciphisa ngempumelelo, ii-micro-cracks zekhonkrithi zinokuthintelwa, kwaye ubomi bezakhiwo bunokwandiswa. Ke ngoko, ikhonkrithi exutywe ne-slag powder iyamkelwa lishishini lokwakha ngenxa yeempawu zayo ezikhethekileyo. I-slag yentsimbi yokusila yodwa ingasetyenziswa njengemveliso yokuvelisa ikhonkrithi kunye nokuxuba ngokweemfuno zemarike, kwaye inokulungiswa ngokweemfuno zokulungisa ubuncinci kunye nobungakanani bokuxuba obuza kulungiswa kwisamente yokuthengiswa.
