1. Mamiriro azvino ekushandisa zviwanikwa zvesimbi slag:

Steel slag poda yakagara yakabatanidzwa muyero yenyika semusanganiswa wesimende.Nhamba huru yekuenzanisa miedzo yakaratidza kuti: Kana iyo chaiyo nzvimbo yesimbi slag poda inopfuura 420m2 / kg, basa rayo rakafanana neiyo blast furnace slag.Iko kusanganiswa kusanganiswa kwesimbi slag poda uye slag poda haigone kungowedzera kuvandudza chikamu chesimbi slag poda muupfu inoumbwa, asi zvakare kuwedzera huwandu hwekutsiviwa kwehupfu hwesimende pahwaro hwekuona kushanda kwekongiri, kuti uenderere mberi. kuderedza mari yekugadzirira kwekrete.Zviripachena zvinogona kuderedza shrinkage deformation yebhainda uye kuvandudza kuputika kwekupokana kwebinder.Izvi zvinoratidza kuti zvigadzirwa zvesimbi slag poda zvine tarisiro yakanaka yemusika.Parizvino, kugadzikana kwevhoriyamu yesimbi slag kunoderedzwa nekuda kwekuvapo kwemahara CaO uye MgO.Iyo yepamusoro yesimbi oxide inowedzera kuoma kwekukuya, iyo yakakwirira simba rekushandisa ye ton slag poda, uye kuoma kwekugadzirisa simbi slag poda.Naizvozvo, huwandu hwekutengesa kwesimbi slag poda musika idiki, iyo inoitawo kuti simbi slag poda ive musika uri kubuda kuti ugadziriswe.

2. kusanganisa kongiri kunopa nzvimbo yekushandisa ultrafine simbi slag kugaya:

Concrete centralized musanganiswa ishanduko huru mukugadzirwa kwemapurojekiti ekuvaka, uye chikamu cheyakagadzirirwa-yakasanganiswa kongiri kunyorera inoratidza mwero wekongiri yekugadzirwa kwemaindasitiri munyika.Kudzidzira kunoratidza kuti kushandiswa kwekongiri yakasanganiswa kunogona kuwedzera kubereka kwevashandi kudarika kaviri, kuchengetedza simende 10% ~ 15%, kuderedza mari yepurojekiti inenge 5%, uye inogona kuvimbisa kunaka kweprojekiti, kuchengetedza ivhu rekuvaka, kuderedza kusvibiswa kweguruva, kuitira kuti kuwana green kuvaka.Iko kuvandudzwa kwekongiri yekutengesa inosimudzira kugadzirwa kwe slag poda uye inowedzera musika wekuda we slag poda.China yakagadzirira-yakasanganiswa kongiri yekusanganisa chirimwa chakavambwa kuma1980s, pakutanga kuShanghai, Jiangsu nedzimwe nzvimbo, nekuda kwekuenderera mberi kwekuwedzera kwehukuru hwekuvaka, kunyanya nekuda kwekukurumidza kuvakwa kwemaguta ekumaodzanyemba kwakadziva kumabvazuva, pamwe chete ne nhevedzano yemitemo inotsigira uye matanho anotorwa nevakuru vekuvaka, kuitira kuti kongiri yakagadzirira-yakasanganiswa yeguta inowedzera ne15% pagore.Nokuti mutengo we slag uye simbi slag yakaderera pane iyo simenti, kongiri yakavhenganiswa ne slag uye simbi slag ine hupfumi uye yakakodzera kushandiswa mune intensively yakasanganiswa yekutengeserana kongiri.Kongiri yakagadzirwa nekusanganisa slag uye simbi slag nesamende, dombo uye jecha yero ine zvakanakira kunonoka kunonoka simba, yakaderera hydration kupisa, kunaka kupfeka kusagadzikana uye yakakwirira kubatanidza simba nesimbi mbariro.Inonyanya kukodzera zvivakwa zvepamusoro-soro, DAMS, nhandare dzendege, nheyo huru dzakadzika uye mapurogiramu epasi pemvura.Parizvino, Ultra-yakakwirira simba kongiri inogadzirwa zvakanyanya nekusanganisa silica ash uye yakanyanya kunaka yekudzikisa mvura, asi kushaikwa kwe silica ash raw materials uye yakanyanya kunaka yekudzikisa mvura inodhura, zvichikonzera kudhura kwekongiri.Nezvakakwirira uye zvepamusoro zvinodiwa zvekongiri hunhu mumapurojekiti makuru-akakosha, kuwedzera kuri kudiwa kwekongiri yekutengeserana kwakavhura musika wakafara wekushandiswa kwakanyanya kweslag nesimbi slag poda.Kunzwisisa kwevanhu kwemaitiro e slag uye simbi slag poda, chinhu chitsva chekuvaka, chiri kuwedzera zvakare.Nekusimudzira uye kushandiswa kwekongiri yekutengeserana munyika uye kushandiswa kwemitemo yenyika ine chekuita ne slag uye simbi slag poda zvigadzirwa, uye kushandiswa kwemitemo yakadai sekurambidza zvakasimba kusanganisa kongiri panzvimbo dzekuvaka mumaguta, misika ye slag nesimbi. slag poda ichave yakawanda uye yakakura, uye kushandiswa kwayo kuchakwezva kutarisisa kwakawanda.

3. maitiro ekugadzirira uye midziyo yesimbi slag micro-powder vertical grinding yave yakakurumbira uye inoshandiswa.

Parizvino, tekinoroji yekukuya yakamira inoshandiswa kukuya simbi slag micro-upfu uye kugadzira zvigadzirwa zvinotsiva high-energy simende clinker, inova yemhando yepamusoro yekugadzira tekinoroji muindasitiri.Munguva yakapfuura, kazhinji slag, simbi slag uye simenti clinker, gypsum, nezvimwewo pamwe chete, maererano nechimwe chikamu chekukuya mukugadzirwa kwekugadzira simenti.Nekuda kwekusagadzikana kwakashata kwe slag uye simbi slag, kukuya hakugone kugadzika zvakanyanya kana kusanganiswa nesamende clinker, kuita kwayo hakugone kugadzirwa zvizere, uye huwandu uye kushandiswa kweslag nesimbi slag kunogumira kune imwe nhanho.Mukugadzirira kweiyo ultrafine poda kubva kusimbi slag chete, Jiangsu iron uye mabhizinesi esimbi ari kumberi.Mabhizinesi akati wandei esimbi anomiririrwa neChangzhou Zhongtian Iron neSimbi akavaka yakakosha simbi slag vertical grinding process mitsara yekugadzira.Sesimbi slag micro-upfu yakatwasuka chigayo mugadziri, HCM Michina inopa tsigiro yehunyanzvi mune yekupedzisira simbi slag yekukuya nzira uye yakakosha vertical mill yekugadzira michina.Hunhu hwayo hwehunyanzvi hunonyanya kutevedzera zvinhu zvinotevera: kusarudzwa kwechigayo chinogaya simbi yehupfu, ine tekinoroji yepamusoro, kugadzirwa kwakavimbika, hukuru hwekuita basa, ine chigayo chakamira kugadzira toni yenzvimbo chaiyo ye400m2/kg ~ 500m2/kg. slag, simbi slag poda, pane yechinyakare bhora chigayo kugadzirwa kwehuremu hwakafanana hwehupfu hunochengetedza magetsi 30% ~ 50%;Iyo yakanaka poda ye slag uye simbi slag inosanganiswa zvakananga mukrete, iyo inochengetedza huwandu hwesamende uye nokudaro inochengetedza kushandiswa kwesimba kwekugadzira simenti.Slag, simbi slag yekukuya maitiro, inogona kuchinjika kugadzirisa kunaka kwezvigadzirwa zvinoenderana nezvinodiwa pamusika.Nekuwedzera kwekuwedzera kwe slag uye simbi slag mukongiri, kupisa kwe hydration uye zviri mukati mezvinhu zvinokuvadza zvekongiri zvinogona kuderedzwa, izvo zvinogadzira mamiriro akanaka ekuvandudza kushanda kwekongiri nekushomeka kwesimba rekushandisa.Iyo simbi slag inogadzika nehupfu hwekukuya, uye zvinhu zvinogadzika munzvimbo ine hunyoro pane tembiricha yepamusoro (100 ℃ ~ 300 ℃).Mazhinji emahara calcium oxide uye yemahara magnesium oxide musimbi slag micro-upfu inoiswa mukati meinoshanda zvakanyanya calcium hydroxide uye magnesium hydroxide.Mukuwedzera, nekuda kwekubatanidzwa kwe slag uye simbi slag mukrete, maitiro e alkali aggregate anogona kunyatsoderedzwa, micro-cracks yekrete inogona kudzivirirwa, uye hupenyu hwezvivakwa hunogona kuwedzerwa.Naizvozvo, kongiri yakasanganiswa neupfu hwe slag inogamuchirwa neindasitiri yekuvaka nekuda kwezvivakwa zvayo zvakasiyana.Kukuya simbi slag chete inogona kushandiswa sechigadzirwa chekugadzira kongiri uye kusanganisa zvinoenderana nezvinodiwa pamusika, uye zvakare inogona kugadziridzwa zvinoenderana nekudikanwa kwekugadzirisa fineness uye kusanganisa huwandu hunogadziriswa kuita simende inotengeswa.

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.
