Indasitiri yesimbi inomira senheyo yezvivakwa zvepasirese, asi inoshanda mune imwe yenzvimbo dzakaomesesa-tembiricha dzePasi. Kubva pakupisa kwakanyanya kwekunyunguduka kwesimbi kusvika kune chaiyo yekukanda simbi, midziyo yakakosha senge ma converter, electric arc furnaces, uye blast furnaces zvinotarisana nekushushikana kusingagumi: zvinofanirwa kushingirira kutarisana netembiricha inowanzopfuura 1,600 ° C, yakabatanidzwa nekukukurwa kwehasha kubva kusimbi yakanyungudutswa uye scalding simbi. Aya mamiriro akanyanya anoisa zvisingaenzaniswi zvinodikanwa pazvinhu zvinoramba-matanho ekudzivirira anodzivirira midziyo kubva mukukuvadzwa-uye pakati pese sarudzo,magnesium-chromium zvidhinhakubuda seyekupedzisira, yakavimbika mhinduro.
Magnesium-chromium zvidhinha zvinokwereta chinzvimbo chazvo chisingaenzaniswi muindasitiri yesimbi kune matatu epakati, asingakundwe zvivakwa zvinogadzirisa marwadzo makuru ega ega ekupisa kwesimbi kugadzirwa. Kutanga, kupikisa kwavo kunoshamisa kwemoto ndeyekuchinja-mutambo kwekuchengeteka nekubudirira: nerefractoriness rating zvakanaka pamusoro pe 1,700 ° C, zvidhinha izvi zvinochengetedza kutendeseka kwavo kwemaitiro kunyange mumoto unopisa wehuni dzesimbi. Kusiyana nemidziyo yakaderera inodzikisira iyo inogona kupfava kana kunyungudika nekupisa kwakanyanya, zvidhinha zvemagnesium-chromium zvinobvisa njodzi yekungoerekana yatadza kushanda kwemidziyo, izvo zvinogona kumisa mitsetse yekugadzira uye kukonzeresa kunonoka kunodhura. Chechipiri, kupikisa kwavo kwepamusoro-slag kunobata zvakananga imwe yematambudziko makuru ekugadzirisa indasitiri yesimbi. Zvidhinha izvi zvakaumbwa nepamusoro-purity magnesium oxide uye chromium oxide, zvidhinha zvinoumba mhinganidzo yakakora, isingapindiki inodzinga zvose alkaline uye acidic slags-zvakajairwa nekugadzirwa kwesimbi inodya pamicheka yakajairwa. Uku kuramba kunowedzera hupenyu hwebindu rechoto ne30% kana kupfuura zvichienzaniswa neyakajairwa refractories, kurova kazhinji mari yekutsiva uye kuderedza nguva isina kurongeka. Chechitatu, yavo yakanakisa yekupisa yekuvhundutsa kugadzikana inovimbisa kuenderana panguva dzakakosha dzekushanda zvikamu. Apo choto chinotanga kana kuvharwa, tembiricha inogona kupetana nemazana emadhigirii munguva pfupi—kushushikana kunoita kuti zvidhinha zvakawanda zvitsemuke kana kuparara. Zvidhinha zveMagnesium-chromium, zvisinei, zvinotora kushanduka uku zvisina simba, zvichichengeta maramba akasimba uye kugadzirwa kuchifamba zvakanaka pasina kukanganisa.
Izvi zvimisikidzo zvinoita kuti magnesium-chromium zvidhinha ive yakakosha padanho rega rega rekugadzira simbi, kubva pakugadzirisa zvinhu kusvika pakukandwa kwekupedzisira. Muma converters uye magetsi arc furnaces, apo simbi inonyungudutswa uye inonatswa, zvidhinha zvinoisa mukati memadziro emukati, zvichitsungirira kukweshwa kwakananga kubva mukuputira simbi yakanyungudutswa uye corrosive slag. Dziviriro iyi inobvumira mavira kuti ashande pamwero wepamusoro kwenguva yakareba, achiwedzera kubuda kwesimbi zuva nezuva. Mumaladhi—midziyo mikuru inotakura simbi yakanyungudutswa kubva muchoto ichiendesa kumichina yokukandira—zvidhinha zvemagnesium-chromium zvinoshanda setambo yakasimba. Ivo vanodzivirira kurasikirwa nekupisa uko kungakanganisa kunaka kwesimbi uye kuvharira kudonha kungangoita, kuve nechokwadi chekuti simbi yakanyungudutswa inosvika padanho rayo rinotevera iri muchimiro chakakwana chekugadzirisa pasi sekukunguruka kana kuforoma. Kunyangwe mumavira anoputika, moyo wekugadzirwa kwesimbi, zvidhinha izvi zvinodzivirira nzvimbo dzakakosha dzepamusoro nedzezasi kubva pakurwiswa kwakabatanidzwa kwegasi rinopisa kwazvo (kusvika 2,000 ° C) uye slag yakanyungudutswa, inochengetedza kwenguva refu, kushanda kwakadzikama kwakakosha pakupihwa kwesimbi nguva dzose.
Kune vagadziri vesimbi vanovavarira kuwedzera kugadzirwa, kuderedza mitengo yekushandisa, uye kuchengetedza mupendero wemakwikwi, kusarudza zvemhando yepamusoro magnesium-chromium zvidhinha haingori sarudzo-icho chinhu chinodiwa. Yedu magnesium-chromium zvidhinha inogadzirwa neakasimba emhando yekudzora, ichishandisa premium mbishi zvinhu zvinoedzwa zvakaomarara kusangana neindasitiri yepasi rose zviyero. Kuvimbwa nezvinotungamira zvidyarwa zvesimbi mhiri kweAsia, Europe, uye North America, zvigadzirwa zvedu zvine rekodhi rekodhi yekuunza kuita kwakafanana, kunyangwe munzvimbo dzinonyanya kudiwa dzekugadzira. Sangana nesu nhasi, uye rega indasitiri yedu inotungamira-inodzivirirwa nemoto isimbise maitiro ako ekugadzira simbi, kuderedza nguva yekudzikira, uye kukubatsira iwe kuwana inoenderera, yenguva refu kukura.
