Mukuita kwekugadzirwa kwesimbi, kuwedzera chimwe chikamu chezvinhu zvealloying zvinogona kuvandudza zvakanyanya kushanda kwesimbi. Ferrosilicon, seyakajairwa alloy zvinhu, inoshandiswa zvakanyanya muindasitiri yesimbi. Kuwedzera kwayo kunogona kuvandudza mhando, mechanical properties uye corrosion resistance yesimbi. Ichi chinyorwa chichasuma kuumbwa, nzira yekuita uye kushandiswa kweferrosilicon musimbi, pamwe nekuita kwayo pakushanda kwesimbi.
Kuumbwa kweferrosilicon:
Ferrosilicon is a alloy material inonyanya kuumbwa nesilicon (Si) uye iron (Fe). Zvinoenderana nesilicon zvirimo, ferrosilicon inogona kukamurwa kuita magiredhi akasiyana, senge yakaderera ferrosilicon (silicon yemukati inenge 15% kusvika 30%), yepakati ferrosilicon (silicon yemukati inenge 30% kusvika 50%) uye yakakwirira ferrosilicon (silicon yemukati inodarika. 50%). Iyo silicon yemukati yeferrosilicon inosarudza mashandisiro ayo uye mhedzisiro musimbi.
Nzira yekuita yeferrosilicon:
Basa referrosilicon musimbi rinonyanya kuratidzwa mune zvinotevera: a. Deoxidizer effect: Iyo silicon iri muferrosilicon inopindirana neokisijeni musimbi pakupisa kwakanyanya kuita se deoxidizer. Inogona kunyatsotora okisijeni musimbi, kuderedza okisijeni mukati mesimbi, kudzivirira pores uye inclusions kubva pakuumbwa panguva yekutonhora, uye kuvandudza kunaka uye simba resimbi. b. Alloying mhedzisiro: Silicon muferrosilicon inogona kugadzira alloy makomisheni nezvimwe zvinhu musimbi. Aya ma alloy makomisheni anogona kushandura chimiro chekristaro chesimbi uye kuvandudza kuoma, kuoma uye kuomesa kwesimbi. c. Wedzera tembiricha yekunyungudika: Kuwedzerwa kweferrosilicon kunogona kuwedzera tembiricha yekunyunguduka kwesimbi, iyo inobatsira pakunyungudika nekukanda simbi.
Kushandiswa kweferrosilicon musimbi:
Ferrosilicon inoshandiswa zvakanyanya muindasitiri yesimbi, kunyanya kusanganisira zvinotevera zvinhu:
1. Kugadzira simbi isina tsvina:
Ferrosilicon, sechinhu chakakosha chekubatanidza, chinoshandiswa mukugadzira simbi isina tsvina. Inogona kuvandudza corrosion resistance, simba uye kupfeka kuramba kwesimbi isina tsvina.
2. High-speed simbi yekugadzira: Ferrosilicon inogona kushandiswa sekuwedzera kwesimbi yepamusoro yekuvandudza kuoma uye kupfeka kupikisa kwesimbi yakakwirira, zvichiita kuti zvive zvakakodzera kucheka zvishandiso, kucheka midziyo uye mabheji.
3. Silicon simbi yekugadzira: Ferrosilicon inoita basa rinokosha mukugadzirwa kwesilicon simbi mumidziyo yemagetsi yakadai semotor, transformers uye jenereta. Silicon muferrosilicon inogona kuderedza iyo magineti permeability musimbi, kuderedza eddy ikozvino kurasikirwa uye kugadzirisa magetsi emagetsi.
4. Kugadzirwa kwepipeline simbi: Kuwedzerwa kweferrosilicon kunogona kuvandudza kusimba uye kushorwa kwesimbi yepombi, kuwedzera hupenyu hwayo hwesevhisi, nekuvandudza mashandiro ekuchengetedza mapaipi.
5. Dzimwe nzvimbo dzekushandisa: Ferrosilicon inoshandiswawo mukugadzirwa kwezvinhu zvinoramba, maindasitiri ekukanda uye welding, nezvimwe.
Mhedzisiro yeferrosilicon pane simbi zvivakwa:
Kuwedzerwa kweferrosilicon kune zvakakosha pakushanda kwesimbi. Izvi zvinotevera zvinokonzeresa ferrosilicon pane simbi zvivakwa:
1. Kuvandudza simba uye kuoma: The alloying effect ye ferrosilicon inogona kuvandudza simba uye kuoma kwesimbi, zvichiita kuti zvive zvakakodzera kune zvikumbiro zvine simba guru rinodiwa.
2. Kuvandudza kusimba kwekuora: Kuwedzerwa kweferrosilicon kunogona kuvandudza kusvibiswa kwesimbi, zvichiita kuti iwedzere kupikisa uye oxidation.
3. Gadzirisa chimiro chekristani: Siricon mu ferrosilicon inogona kuumba alloy compounds nezvimwe zvinhu musimbi, gadzirisa crystal structure yesimbi, uye kuvandudza maitiro ayo emagetsi uye kupisa kwekushisa.
4. Kuvandudza kushanda kwekugadzirisa: Kuwedzerwa kweferrosilicon kunogona kuvandudza machinability yesimbi, kuderedza kuoma kwekugadzirisa, nekuvandudza kushanda kwekugadzira.
Sechinhu chakakosha alloy zvinhu, ferrosilicon ine huwandu hwakawanda hwekushandisa uye kukosha muindasitiri yesimbi. Iyo ine mhedzisiro yakanaka pamhando, mechanical zvivakwa uye corrosion kuramba kwesimbi kuburikidza nemaitiro akadai se deoxidizer, alloying uye kuwedzera kunyungudika tembiricha. Ferrosilicon ine maapplication akakosha mukugadzira simbi isina tsvina, kugadzirwa kwesimbi inomhanya-mhanya, kugadzira simbi yesilicon, kugadzira simbi yepombi nemimwe minda, uye ine mhedzisiro yakakosha pakusimba, kuoma, kusaora uye kugadzirisa zvinhu zvesimbi. Saka, zvakakosha kunzwisisa kuumbwa kweferrosilicon.
