Nozzle yanga?

Izina rya Nozzle ritunganijwe rikomoka ku gikorwa cyaryo - ijambo "nozzle" risobanura neza uruhare rwayo nk'umuyoboro washonga, mu gihe "kunoza" byerekana kuramba mu bushyuhe bwinshi. Ukurikije imikoreshereze yihariye, nozziles yoroshye irashobora kugabanywamo ubwoko bwinshi, nko mu masoko yo hejuru, nozzles, akazuriro ka nozzles, ibishusho bitwikiriye, nibindi bitandukanye bihuye nibisabwa.

Nozzle yanga?

Nozzle Nozzle nigicuruzwa cyoroshye gikoreshwa mubushyuhe bukabije (nko gusebanya) cyangwa ibyuma bidashizwemo, mubisanzwe byashyizwe kumurongo wibikoresho bya metallurgical (nka galege, tundish).

Iremeza umutekano n'umutekano wibikorwa binuka no gutakaza neza muguhuza neza igipimo cyurugendo, igipimo cyingendo nigikorwa cyurugendo rwishonga. Nozzles Nozz idakeneye gusa kwihanganira ubushyuhe bukabije (mubisanzwe birenga 1500 ° C), ariko nanone bigomba kurwanya isuri, yangiza, kandi byangiritse ku mutima no gushonga.

Ibigize n'ibikoresho byo kunozwa nozzles

Imikorere ya Nozzles Nozzles biterwa no guhitamo ibikoresho no gushushanya. Ibikurikira nibice byingenzi nibiranga ibintu:

1. Ibikoresho by'ingenzi

Aluminum carbone (al₂o₃-c): Umuyoboro muremure (al₂o₃) ikoreshwa nkibice nyamukuru, nibikoresho bya karubone (nka graptite) byongerwa no kurwanya isuri. Aluminum Carzles Nozzs ikoreshwa cyane mumisoro no guturika, kandi birakwiriye guta ibyuma bisanzwe bya karubone.
Aluminium zirconium karubone (al₂o₃-zro₂-c): Zroconide ya karubone yo kunoza aluminiyumu kugirango igabanye isuri ndende yubushyuhe kandi ikwiranye na manganese ibyuma cyangwa andi manota adasanzwe.
High-alumina: Hamwe na balumina-alumina
Magnesium-karubone (mgo-c): hamwe na magnesium oxide (mgo) nka matrix, ibikoresho bya karubone, bikwiranye, bikwiranye na alkalinity-amanota yihariye.
Quused Quarz: ikoreshwa mugutera stel-carbone ibyuma cyangwa imurikagurisha ridatuje, ifite ubuhanga bwo guhungabanya ubushyuhe, ariko intege nke zitungurana, ariko intege nke zo guhinga.
Ibikoresho bigizwe: nko guhuza nozzles hamwe na zirconuum ore hamwe na aluminium yo hanze, huza ibyiza byibikoresho bitandukanye kugirango utezimbere imikorere.

2. Igishushanyo mbonera

Nozzlesmubisanzwe bya silindrike cyangwa bifitanye isano, hamwe nu muyoboro utemba imbere (aperture muri rusange 10-100 mm) kugirango ugenzure igipimo cyashonga. Nozzles (nko kwibiza nozzles) yateguwe hamwe nuburyo bwihariye, nkimwobo wubutaka, kugirango utezimbere ikwirakwizwa ryumurima washongeshejwe muri kristalizer. Igice cyo hanze gishobora gutwikirwa injyana yicyuma (nkicyuma cyicyuma) kugirango yongere imbaraga zubururu kandi ikumira imiti ya cluck.

3. INGARUKA ZIKURIKIRA

Kunoza imikorere, inyongera zikurikira ziyongeraho kwanga nozzles:

Antioxidants: nka silicon (si) na aluminium (al) infura, kugirango wirinde ibikoresho bya karubone kuva ku bushyuhe bwo hejuru.

Stabilizers: nk'inka nka calcium (cao) na magnesium (MGO), kuzamura imiti irwanya isuri hamwe n'isuri.

Bunders: nk'ibisibo na asfalt, kunoza imbaraga zo kubumba no gushikama ubushyuhe bwinshi.

Imikorere yo kohereza nozzles

Nozzles Nozzles ikora imirimo myinshi yingenzi mubushyuhe bwa meturgique:

1. Kugenzura

Nozzles Nozzles igenzura neza igipimo cyurugendo no gutembera kwuzuza ubunini nuburyo bwimiyoboro yimbere. Kurugero, muburyo bukomeza bwo gutahura, nozzle yarenze hamwe na sisitemu yo kunyerera kugirango uhindure umuvuduko aho ibyuma byashongesheje kugirango wirinde inenge zatewe no kwihuta cyangwa gutinda cyane.

2. Kurinda gushonga

Nozzle yarengewe yinjira muri kristu yo gukumira ibyuma byashongeshejwe mu kirere, kugabanya okiside no gushiraho okiside no kuzamura ireme rya billet. Byongeye kandi, igishushanyo mbonera cyurukuta rwimbere cyurukuta rushobora kugabanya imivurungano mumurongo washonga kandi igabanya ibyago byo gucika.

3. Ubushyuhe bwo hejuru no kurwanya isuri

TheNozzleakeneye kwihanganira ingaruka za lilten ibyuma cyangwa slag kuri 1500-1700 ° C. Kurangwa neza hamwe nisuno yo kurwanya isuri komeza ko ikomeje kuba ihamye mugihe kinini no kurangiza ubuzima bwa serivisi.

4. Guhungabana neza

Iyo umudozi asimbuwe cyangwa casting yatangiye arahagarara, nozzle izagira impinduka zikarishye. Ubunini bworoshye bwo kohereza ibintu bigabanya ibyago byo guhungabana kwubushyuhe no guhitamo ibikoresho nibishushanyo mbonera.

5. Irinde gufata

Kuburyo-busanzwe cyangwa Calcium ikubiyemo ibyuma, intangarugero ya Alumina irashobora kwakozwe mubuseri bwashongeshejwe, bigatera urutoki. Nozzles Nozz ikoresha ibikoresho byo kurwanya ingufu (nkibikoresho bikubiyemo CAO) kugirango wirinde gufunga utanga ibintu bitoroshye (nka Cao · al₂o₃).

Gusaba imirima yo kohereza nozzles

Nozzles Nozz ikoreshwa cyane mumirima ikurikira:

1. Icyuma na Steel Metallurgy

Umuhanda: Nomero yo hejuru kandi yo hepfo ikoreshwa hepfo yumuhanda, kandi ifatanya na sisitemu yo kunyerera kugirango igenzure ibyuma byashongeshejwe bihumura.
Tundush: Gukusanya nozzle hamwe na nozzle yibiza bikoreshwa muguhitamo ibyuma bihumura bivuye kuri tundish kugeza kuri kaburimbo kugirango uhindure inzira ikomeza.
Guhindura no gutanura amashanyarazi: Nozzles Nozzles ikoreshwa mu ibyuma kugirango ihangane isuri yubushyuhe bwo hejuru ikonje kandi irasetsa.

2. Icyuma kitari ferrose

Mu gushonga imyanda idahumuriza nka aluminium, umuringa, na magnesium, nomero no kuvugurura no guta no guterana, nko kuyobora muri aluminium inkubite.

3. Inganda zikirahure na Ceramic

Nozzles Nozzs ikoreshwa mugukoresha urujya n'uruza rw'ikirahure cy'ikirahure cyangwa ceramic, kandi bigomba kuba bifite imbaraga zo kurwanya ruswa no gushikama.

4. Izindi nganda ndende

Nka myandara yimyanda, imiti-yubushyuhe-ubushyuhe-burebure, nibindi, Nozzles Nozzles ikoreshwa mugusohora cyangwa kwanduza amazi menshi.

Inzira yumusaruro wo kohereza nozzles

Umusaruro wo gutunganya nozzles urimo inzira nyinshi zigoye kugirango tumenye ko imikorere yabo ihura nibipimo byinganda:

1. Guhitamo ibikoresho fatizo n'ibiyigize
Hitamo ubunebwe burenze, zirconuum oxide, igishushanyo nibindi bikoresho fatizo, kandi bigenzura byimazeyo umwanzi. Ongeramo Antioxidants, binders, nibindi ukurikije ibipimo bya fortila hanyuma urombe neza.

2. Kubumba
Koresha ingwate zo gusiganwa mu isostatike cyangwa umuvuduko mwinshi kugirango umenye neza ko imiterere ya Nozzle aringaniye kandi umuyoboro utemba urasobanutse. Nozzles (nko kwibiza nozzles) bigomba gushingwa muburyo bugoye nibibumba.

3. Kurwana
Kurwara ku bushyuhe bwo hejuru (1400-1800 ° C) mu kirere kitagira ikirere cyangwa kirinzwe (nka azote) byongera imbaraga z'umubiri no kurwanya ubushyuhe. Ibicuruzwa bimwe bikoresha ibihe bya kabiri cyangwa kuvura ubushyuhe kugirango uteze neza imikorere.

4. Kuvura hejuru
Polonye Umuyoboro utemba cyangwa ukoreshe urwego rwo kurwanya (nka Zro₂ Gukunda) Gutezimbere Kurwanya Ibitero n'amazi. Igice cyo hanze gishobora gutwikirwa hamwe nicyuma cyangwa kuvura ibisate.

5. Kugenzura ubuziranenge
Uburozi, bikata hamwe nukuri guhuza nozzle bigenzurwa nuburyo budapima ibizamini byangiza nka x-imirasire kandi ultrasound. Imikorere yimikorere inoze hamwe nisuka igenzurwa nibizamini bya laboratoire.

Ibyiza byo Kuzuza Nozzles

Gushyira mu bikorwa byinshi byo kunozwa mu nganda z'ubushyuhe bwinshi bikomoka ku nyungu zikurikira:

Kurambagiza cyane: Ibikoresho byiza cyane kandi inzira zirashobora kugerwaho igihe kirekire mubidukikije bikabije, kandi ubuzima bumwe bushobora kugera kumasaha menshi kugeza muminsi myinshi.
Kugenzura neza: Ibisobanuro byukuri byumurongo utemba ukurikira ituze ryumutekano wo gushonga kandi utezimbere ubuziranenge bwibicuruzwa.
Kurwanya isuri: Ifite imbaraga zikomeye ku isuri ya chimique n'isuri y'imashini yashongeshejwe ibyuma hanyuma ikagabanya ibiciro byo kubungabunga.
Ubushyuhe bwo Guhungabana: Ihuriro ryibikoresho rifite intego rigabanya ibyago byo gutungurwa nubushyuhe kandi ugahuza ibisabwa kugirango utangire-guhagarika.
Igishushanyo gitandukanye: Nozzles yubwoko butandukanye hamwe nibisobanuro bihuye nibisabwa bitandukanye kandi bifite ibintu byinshi byakira porogaramu.

Nkikibaya cyibanze cyubushyuhe bwinshi, Nozzle Nozzle ihuza imirimo myinshi nko kurwanya ubushyuhe bwinshi, kurwanya ruswa no kugenzura. Nibyingenzi "inyuma-inyuma-amatara intwari" mucyuma na stel metallurgie, icyuma cya ferrose gishonga nizindi nganda.
