1. Mamiriro aripo pari zvino ekushandiswa kwesimbi yakaora:

Upfu hwesimbi hwakagara huchibatanidzwa muchiyero chenyika semusanganiswa wesimende. Miedzo yakawanda yekuenzanisa yakaratidza kuti: Kana nzvimbo chaiyo yeupfu hwesimbi hwesimbi iri kupfuura 420m2/kg, basa rayo rakafanana nereblast furnace slag. Kusanganiswa kweupfu hwesimbi hwesimbi nehupfu hweslag hakungogone chete kuwedzera huwandu hweupfu hwesimbi hweslag muupfu hwakabatanidzwa, asiwo kuwedzera huwandu hwehupfu hwakabatanidzwa nesimende zvichibva pakuona kushanda kwekongiri, kuitira kuderedza mutengo wekugadzirira kongiri. Zviri pachena kuti zvinogona kuderedza shrinkage deformation yebinder uye kuvandudza kupwanyika kwebinder. Izvi zvinoratidza kuti zvigadzirwa zveupfu hwesimbi hweslag zvine mukana wakanaka wemusika. Parizvino, kugadzikana kwehuremu hwesimbi hweslag kunodzikira nekuda kwekuvapo kweCaO neMgO yakasununguka. Hunhu hwakawanda hweiron oxide hunowedzera kuoma kwekukuya, kushandiswa kwesimba kwakanyanya kweton slag powder, uye kuoma kwekugadzirisa upfu hwesimbi hweslag. Saka, huwandu hwekutengesa hwemusika weupfu hwesimbi hwakaderera, izvo zvinoitawo kuti upfu hwesimbi huve musika uri kubuda kuti uvandudzwe.

2. Kusanganisa kongiri kunopa nzvimbo yekushandisa simbi yakatsetseka zvikuru:

Kusanganisa kongiri pakati pemakongiri ishanduko huru mumapurojekiti ekugadzira, uye huwandu hwekushandiswa kwekongiri yakasanganiswa hunoratidza huwandu hwekugadzirwa kwekongiri mumaindasitiri munyika. Maitiro anoratidza kuti kushandiswa kwekongiri yakasanganiswa kunogona kuwedzera kugona kwevashandi nekanopfuura kaviri, kuchengetedza simende ne10% ~ 15%, kuderedza mari yepurojekiti neinenge 5%, uye kunogona kuve nechokwadi chemhando yepurojekiti, kuchengetedza ivhu rekuvaka, kuderedza kusvibiswa kweguruva, kuitira kuti kuvaka kuite green. Kugadzirwa kwekongiri yekutengeserana kunokurudzira kukura kwekugadzirwa kwehupfu hweslag uye kunowedzera kudiwa kwehupfu hweslag. Chigadzirwa chekusanganisa kongiri yakasanganiswa muChina chakavambwa muma1980, pakutanga muShanghai, Jiangsu nedzimwe nzvimbo, nekuda kwekuwedzera kuri kuramba kuchiitwa kwehukuru hwekuvaka, kunyanya nekuda kwekukura nekukurumidza kwekuvakwa kwemaguta ekumaodzanyemba kwakadziva kumabvazuva, pamwe chete nehurongwa hwakatevedzana hwekutsigira uye matanho anotorwa nevakuru vekuvaka, kuitira kuti kongiri yakasanganiswa muguta iwedzere ne15% pagore. Nekuti mutengo weslag nesimbi wakaderera pane wesimende, kongiri yakasanganiswa neslag nesimbi slag inodhura zvishoma uye yakakodzera kushandiswa mukongiri yekutengeserana yakasanganiswa zvakanyanya. Kongiri yakagadzirwa nekusanganisa slag nesimbi slag nesimende, matombo nejecha yeyero ine zvakanakira zvekusimba kwakanyanya kunonoka, kupisa kushoma, kuramba kupfeka zvakanaka uye simba rekubatanidza rakawanda nesimbi. Yakakodzera zvakanyanya zvivakwa zvepamusoro, madhamu, nhandare dzendege, nheyo dzakakura dzakadzika uye mapurojekiti epasi pemvura. Parizvino, kongiri yakasimba kwazvo inonyanya kugadzirwa nekusanganisa silica ash uye mvura inoderedza simba, asi kushaikwa kwezvinhu zvakagadzirwa ne silica ash uye mvura inoderedza simba zvinodhura, zvichikonzera mutengo wakakwira wekongiri. Nekuda kwezvinodiwa zvepamusoro zvehunhu hwekongiri mumapurojekiti makuru akakosha, kudiwa kuri kuwedzera kwekongiri yekutengeserana kwakavhura musika wakakura wekushandiswa kwakawanda kweslag nesimbi slag powder. Kunzwisisa kwevanhu hunhu hweslag nesimbi slag powder, chinhu chitsva chekuvaka, kuri kuwedzerawo. Nekusimudzirwa nekushandiswa kwekongiri yekutengeserana munyika uye kushandiswa kwemitemo yenyika ine chekuita nezvigadzirwa zveupfu hweslag nesimbi, uye kushandiswa kwemitemo yakaita sekurambidza kusanganisa kongiri panzvimbo dzekuvaka munzvimbo dzemaguta, musika weupfu hweslag nesimbi uchawedzera kukura, uye kushandiswa kwayo kuchakwezva kutariswa kwakawanda.

3. Maitiro ekugadzirira uye zvishandiso zvesimbi slag micro-upfu hwakamira hwakanyanya kufarirwa uye zvakashandiswa

Parizvino, tekinoroji yekukuya yakamiswa inoshandiswa kukuya simbi ine hupfu hudiki uye kugadzira zvigadzirwa zvinotsiva simende ine simba rakawanda, iyo iri tekinoroji yepamusoro yekugadzira muindasitiri. Kare, kazhinji slag, simbi ine hupfu uye simende ine hupfu, gypsum, nezvimwewo pamwe chete, zvichienderana nehuwandu hwakati hwekugaya mukugadzirwa kwesimende. Nekuda kwekusagona kukora kwe slag nesimbi, kukuya hakugone kukuyiwa zvakanaka kana kusanganiswa ne cement clinker, mashandiro ayo haagone kugadzirwa zvizere, uye huwandu nekushandiswa kwe slag nesimbi zvine mwero wakati. Mukugadzira ultrafine powder kubva kusimbi ine hupfu chete, mabhizinesi esimbi nesimbi eJiangsu ari pamberi. Makambani akati wandei esimbi anomiririrwa neChangzhou Zhongtian Iron and Steel akavaka mitsetse yakakosha yekugadzira steel slag vertical process. Semugadziri wesimbi ine hupfu hudiki hwe vertical mill, HCM Machinery inopa rutsigiro rwehunyanzvi munzira yekukuya steel slag grinding uye kugadzira michina mikuru ye vertical mill. Hunhu hwayo hwehunyanzvi hunonyanya kutaurwa nezvezvinhu zvinotevera: kusarudzwa kwehupfu hwesimbi inogaya simbi yakagaya vertical mill, ine tekinoroji yepamusoro, kugadzirwa kwakavimbika, hunhu hwebasa rakawanda, ine vertical mill yekugadzira tani yenzvimbo chaiyo ye400m2/kg ~ 500m2/kg slag, hupfu hwesimbi inogaya vertical, kupfuura kugadzirwa kwechinyakare kwebhora mill ine huremu hwakafanana hwemagetsi anochengetedza hupfu 30% ~ 50%; Hupfu hwakatsetseka hweslag nesimbi inogaya zvakananga mukongiri, izvo zvinochengetedza huwandu hwesimende uye nokudaro zvinochengetedza kushandiswa kwesimba rekugadzira simende. Slag, maitiro ekugaya simbi inogaya, inogona kugadzirisa kupfava kwezvigadzirwa zvinoenderana nezvinodiwa nemusika. Nekuwedzera kwekuwedzera kweslag nesimbi inogaya mukongiri, kupisa kwemvura uye huwandu hwezvinhu zvinokuvadza zvekongiri zvinogona kuderedzwa, izvo zvinogadzira mamiriro akanaka ekuvandudza mashandiro ekongiri nekushandiswa kwesimba kwakaderera. Slag yesimbi inogaya vertical grinding powder, uye zvinhu zvinogaya munzvimbo ine hunyoro pakupisa kwakanyanya (100℃ ~ 300℃). Ruzhinji rwe calcium oxide yakasununguka uye magnesium oxide yakasununguka muupfu hwesimbi hunonyungudutswa kuita calcium hydroxide inoshanda zvikuru uye magnesium hydroxide. Pamusoro pezvo, nekuda kwekuiswa kweslag nesimbi mukongiri, kushanda kwealkali aggregate kunogona kuderedzwa zvinobudirira, kutsemuka kwekongiri kunogona kudzivirirwa, uye hupenyu hwezvivakwa hunogona kuwedzerwa. Naizvozvo, kongiri yakasanganiswa neupfu hweslag inogamuchirwa neindasitiri yekuvaka nekuda kwehunhu hwayo hwakasiyana. Kukuya simbi chete kunogona kushandiswa sechigadzirwa chekugadzira kongiri nekusanganisa zvinoenderana nezvinodiwa pamusika, uye kunogonawo kugadziriswa zvichienderana nezvinodiwa zvekugadzirisa kupfava uye huwandu hwekusanganisa hunofanira kugadzirwa kuita simende yekutengeswa.

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.
