Munguva pfupi yapfuura, mutsetse wekugadzira upfu hwesimbi ine simba guru rekugadzira muChina wakapedzwa uye wakatanga kushanda muShagang Group. Mari yese inoshandiswa pachirongwa ichi inosvika mamiriyoni zana nemakumi manomwe eyuan, uye zvinofungidzirwa kuti matani mazana matanhatu eupfu hwesimbi huchagadzirwa gore rega rega. Nekuda kwekuoma kwakanyanya kwesimbi, dhayamita yezvidimbu zvechigayo chebhora neroller mill ichiri 6-8mm mushure mekupwanywa, izvo zvinoda kuti mabhizinesi ekugadzira simende agadzirise zvakare.tsvina yesimbichigayo chinotenderera chakamira Inoshandiswa mukugadzirwa kwesimbi yeShagang, iyo "inosiya" zvakananga chinobatanidza chepakati. Kukora kwesimbi yesimbi kunogona kusvika 0.003mm. Zvichibva pakuderedza kushandiswa kwesimba kwemaitiro aya, inogona kuderedza njodzi dzezvakatipoteredza, kuwedzera kukosha kwechigadzirwa, kukurudzira kushandurwa kwesimbi yesimbi kubva ku "marara akaoma" kuenda ku "chigadzirwa", uye kuwana "kuvandudzwa kaviri" kwezvibatsiro zvekuchengetedza zvakatipoteredza uye mabhenefiti ehupfumi. Izvi zvinoratidza kuti simbi yesimbi ine mukana wakanaka wemusika. Semuchina wehunyanzvi wesimbi ye slag vertical roller mill, HCMilling (Guilin Hongcheng) ichaunza kushandiswa kwesimbi ye vertical roller mill pamusika.

kukuya kwesimbichigayo

Zvinonzwisisika kuti "kukuya simbi" ipurojekiti yekudzivirira zvakatipoteredza inozivikanwa neindasitiri, chirongwa chehupfumi chinogona kushandiswazve, uye zvakare "nhanho yechipiri" yekurapa simbi yesimbi muShagang. Muna 2020, Shagang ichavaka chirongwa chikuru chekurapa simbi yesimbi ye3.3 miriyoni matani muChina, uye ichawana kushandiswa kwakazara kwesimbi yesimbi kuburikidza nekuparadzanisa magnetic, kupwanya, kukuya tsvimbo, kuongorora uye kumwe kugadzirisa kwakadzika. Pakupera kwaGumiguru wegore rimwe chete, matani anoda kusvika mazana matanhatu esimbi yeShagang yakashandiswa zvinobudirira muchirongwa chekuchinja sponge chemigwagwa yemuguta reZhangjiagang. Mushure mekukuya kwesimbichigayoMutsetse wekugadzira watanga kushanda, tsvina yesimbi yachinja kubva pa "marara akaoma" kuenda ku "chigadzirwa", uye zviwanikwa zvekudzokorodza zvave "zvaoma uye zvakasvinwa", zvichiwedzera cheni yezvehupfumi yakasvibira. "Upamhi hwezvinhu zvakagadzirwa i6-8mm, tobva tazvikuya zvakare nesimbi slag vertical roller mill, uye hutete hunosvika pa 0.003mm mudhayamita." Sekureva kwenyanzvi kubva kuShagang New Materials Co., mutsetse wekugadzira slag wesimbi wakajairika unosvika matani 300000 muindasitiri yese. Mutsetse wedu mutsva wekugadzira matani 600000 ireferensi yeindasitiri yese uye inobatsira zvikuru pakuumbwa kwemitemo inoshanda yeindasitiri.

Tsvagiridzo pamusoro pekugadzirwa nekushandiswa kweupfu hwesimbi hunonzi slag micro powder inyaya inonyanya kutaurwa mushure mekushandiswa kukuru kweupfu hwesimbi hunonzi slag micro powder mumakore achangopfuura. Kugadzirwa kweupfu hudiki kana hupfu hudiki hunonzi slag nesimbi kunogona kubvisa mutsauko mukukweshwa kwekugadzirwa kwesimende yesimbi inonzi slag. Kana simbi inonzi slag yakakuyiwa kusvika yanyatsonaka netsvina yesimbi chigayo chinotenderera chakamira, kana nzvimbo chaiyo yepamusoro ichipfuura 400m2Kg, simbi yesimbi inogona kubviswa zvakanyanya. Chimiro chekristaro chezvinhu chinogadziriswazve nekukuya kwakapfava, uye mamiriro epamusoro pechinhu chinoshanduka. Pamusoro pacho panogona kunatsiridza uye kukurudzira mashandiro esimbi, zvichipa simba kune hunhu hwezvinhu zvekusimbisa zvehydraulic. Kana hupfu hwesimbi hweslag nehupfu hweslag zvasanganiswa, zvine mukana wekuisa panzvimbo imwe chete. Calcium hydroxide inoumbwa kana C3S neC2S musimbi yeslag zvanyoroveswa ndiyo inonyanya kuunza slag. Ruzivo rwazvino rwunoratidza kuti kunyangwe kushandiswa kweupfu hweslag semusanganiswa wekongiri kunogona kuvandudza simba rekongiri uye kuvandudza kushanda uye kugara kwenguva refu kwemusanganiswa wekongiri, alkalinity yakaderera yeblast furnace slag (% CaO+% MgO)/(% SiO2+% Al2O3), inenge 0.9~1.2, ichaderedza zvakanyanya alkalinity ye liquid phase mukongiri, ichakuvadza passive film yekusimbisa mukongiri (pH<12.4 iri nyore kukuvara), uye inokonzera ngura yekusimbisa mukongiri. Pamusoro pezvo, blast furnace slag i vitreous body ine C3AS neC2MS2 sezvikamu zvikuru. Kugona kwe granular blast furnace slag powder kunobva mukuputsika kwe slag vitreous structure. Hydration products inogona kuumbwa chete pasi peCa (OH) 2. Steel slag ine alkalinity yakakwira (% CaO+% MgO)/(% SiO2), inova inenge 1.8~3.0. Zvicherwa izvi zvinonyanya kuva C3S, C2S, CF, C3RS2, RO, nezvimwewo. FCaO nezvicherwa zvinoshanda zviri musimbi zvinogadzira Ca (OH) 2 kana zvasangana nemvura, izvo zvinovandudza alkalinity yemvura yekongiri. Inogona kushandiswa sealkaline activator yeslag powder. Kongiri yakasanganiswa nesimbi slag powder ine hunhu hwesimba guru munguva inotevera. Saka, slag yesimbi neslag composite powder zvinogona kudzidza kubva kune mumwe nemumwe, uye mashandiro acho akanaka kwazvo.

Maitiro ekugadzira tsvina yesimbi chigayo chinotenderera chakamira Yakabatanidzwa nekupwanya, kukuya, kuomesa uye kusarudza hupfu, izvo zvinoratidzwa nekushandiswa kwesimba shoma, kushanda zvakanaka kwekuvhara, nzvimbo diki yepasi, maitiro ari nyore, nezvimwewo. Kupfava kunodiwa uye kugoverwa kwehukuru hwezvimedu zvinogona kuwanikwa nekugadzirisa kumhanya kwekutenderera kwepoda concentrator, mwero wekuyerera kwemhepo yemuchina wemuchina uye kumanikidzwa kwekukuya. Nekuchinja kwenzira dzekugadzira nepfungwa uye tekinoroji yemaitiro iri kukura, mari inoshandiswa mu vertical roller mill system inodzikira zvakanyanya, iyo yakaenzana kana kuti yakakwira zvishoma pane iyo ye closed circuit ball mill system. Nekuda kwezvakanaka zvayo mukushanda uye kushandiswa kwesimba, sisitimu iyi ichashandiswa zvakanyanya. HCMilling (Guilin Hongcheng) inyanzvi yekugadzira simbi slag vertical roller mill. YeduHLM simbi slagchigayo chinotenderera chakamira chishandiso chakanakira kubatsira chigayo chesimbi chinotenderera kuti chiwedzere musika weupfu hwesimbi. Chinogona kukuya upfu hwesimbi hune nzvimbo yepamusoro inodarika 700, kuchengetedza maitiro maviri ekutanga nekukuya kwekupedzisira, uye kupedzisa kugadzirwa kweupfu hwesimbi husina kusimba nedanho rimwe chete.

Kana muine zvinodiwa zvakakodzera, ndapota taurai nesu kuti muwane ruzivo rwakakwana nezvemidziyo yacho.
