Intangiriro no Gushyira mu bikorwa ibikoresho bya SCH12

SCH12 ni ubushyuhe bwa austenitike - ibyuma birwanya ibyuma bikurikiza inganda z’Ubuyapani, cyane cyane byubahiriza ubushyuhe bwa JIS G 5122 Nka chromium ndende - ubushyuhe bwa nikel - ibyuma birwanya ibyuma, ni ibikoresho bisanzwe byo guta ibikoresho byo mu rwego rwo hejuru - ibikoresho by’inganda bitewe n’ubushyuhe buhanitse - ibikoresho by’ubushyuhe, ubushyuhe bw’umuriro hamwe n’ibishobora kwangirika, kandi bihwanye n’icyuma cya SUS302B.

I. Ibyingenzi Ibikoresho bya SCH12
1. Ibigize imiti (Igice kinini,%)
Iranga intangiriro ya chromium - nikel igizwesisitemu ya alloy sisitemu, hamwe na molybdenum (max 0.5%) yongeweho nkuko bisabwa kugirango igenzure neza ubushyuhe bwumuriro hamwe nubukanishi. Urutonde rwihariye rugizwe nuburyo bukurikira:

2. Ibyingenzi byingenzi bya mashini (Nka - cast)

Irerekana ibikoresho byiza byubukanishi, byujuje umutwaro - byujuje ibisabwa munsi yubushyuhe bwo hejuru - imiterere yubushyuhe butagira plastike ihambaye:

Imbaraga Zitanga: Biruta cyangwa bingana na 235 N / mm² (MPa)

Imbaraga za Tensile: Ziruta cyangwa zingana na 490 N / mm² (MPa)

Kurambura: Birarenze cyangwa bingana na 23%

Gukomera kwa Brinell: Hafi ya 123 HB (nyuma yo kuvura ubushyuhe)

3. Ibyingenzi Byumubiri nubushyuhe - Ibintu birwanya

Coefficient yo kwagura ubushuhe: 16.2 × 10⁻⁶ / dogere kuri 0 - 100 dogere, 20.2 × 10⁻⁶ / dogere kuri dogere 0-650, hamwe nibiranga kwaguka k'ubushyuhe bikwiranye nubushyuhe bwo hejuru bwubushyuhe bwo hejuru;

Ubushyuhe - Ubushyuhe budashobora kwihanganira: Bishobora gukora igihe kirekire - igihe kirekire gihamye ku bushyuhe buri hejuru ya dogere 650, bikoreshwa mubikoresho byo mu nganda n'ubushyuhe -;

Imiterere ya Metallographic: Matrisa ya Austenitike hamwe no kurwanya umunaniro ukabije wumuriro, ntabwo ikunda gucika kubera ihinduka ryubushyuhe butunguranye;

Ibindi Byiza: Non - magnetique, castable nziza, kandi irashobora gutabwa mubice bigoye -.

4. Kurwanya ruswa

Dushingiye kuri chromium nyinshi ya 18% -23%, firime yuzuye ya Cr₂O₃ oxyde ikorwa byoroshye hejuru, itanga imbaraga nziza kuriitangazamakuru rya alkaline nibidukikije byoroheje byangiza, kandi irashobora kwihanganira isuri kubitangazamakuru bitangirika byangiza ibidukikije. Nyamara, kurwanya kwangirika kwayo bizagabanuka mubidukikije byangirika nka acide ikomeye hamwe nu munyu mwinshi wa chloride.

II. Uburyo busanzwe bwo gusaba bwa SCH12

Nkubushyuhe - ibyuma birwanya ibyuma, SCH12 irakwiriye cyane cyane guta ibikoresho byinganda munsigiciriritse kandi kinini - ubushyuhe, ibihe byo gusiganwa ku magare bitwara imizigo runaka, cyane cyane kubintu bigoye byakozwe na casting. Imikorere isanzwe ikoreshwa niyi ikurikira:

1. Umwanya w'amashanyarazi

Nibimwe mubikoresho byibanze kuriturbine blade, guhuza nubushyuhe bwo hejuru - igice cyubushyuhe gikora ibidukikije byamazi ya turbine, kandi birashobora kwihanganira gusukwa kwinshi - ubushyuhe bwubushyuhe, gusiganwa ku magare hamwe nimbaraga za centrifugal. Kurwanya umunaniro hamwe nubuzima bwa serivisi birashobora kurushaho kunozwa binyuze muburyo bwiza bwo gukina. Irakoreshwa kandi murwego rwo hejuru kandi rurerure - ubushyuhe bwubushyuhe bwa gaz turbine na generator.

2. Umwanya wo gutekesha hamwe nigitutu

Irashobora gukorwahejuru - ubushyuhekubitereko byinganda hamwe nigitutu cyamashanyarazi, nkibikoresho byo mu itanura ryimbere, ubushyuhe -, imashini zidashobora kwihanganira, guhuza imyanda, nibindi. Byahujwe nubushyuhe bwakazi burenze dogere 300, umuvuduko wamagare hamwe nubuziranenge bwamazi ya alkaline mubibiko (bihuza cyane nakazi k’umuvuduko ukabije w’amashanyarazi y’amashanyarazi yavuzwe haruguru), byujuje ibyangombwa byo kurwanya ubushyuhe, gufunga no gukanika imashini -.

3. Ibikoresho byo gutunganya ibyuma n'ubushyuhe

Byakoreshejwe Kuriitanura ryumubiri, ubushyuhe - inkunga irwanya, ibiseke / ibikoreshoy'itanura rya metallurgiki hamwe n’itanura ritunganya ubushyuhe, rishobora kwihanganira imishwarara y’ubushyuhe yo hejuru - hamwe n’ubushyuhe bwo gutwara amashyanyarazi mu itanura, kandi ikarwanya isuri n’ikirere cyoroheje cyangirika mu itanura, bigatuma ibikoresho birebire - bikora neza.

4. Rusange Rusange Yinganda {{1} Equipment Ubushyuhe

Birakurikizwa kurigiciriritse kandi kinini - pompe yubushyuhe hamwe na valve, ibyuma bishyushya umuyaga ushyushye, ubushyuhe - ibikoresho birwanya ibikoresho byumyemu nganda zubaka ibikoresho byubaka, cyane cyane bikwiranye nibice byubatswe bisaba gukora casting kandi bifite ibisabwa hejuru yubushyuhe bukabije - nubushyuhe bwumuriro.

III. Ibyiza Byibanze no Gushyira mu bikorwa Ingingo z'ingenzi z'ibikoresho

1. Ibyiza Byibanze

Kurwanya Ubushyuhe buhebuje: Matrisa ya austenitike ihujwe na chromium ndende - nikel ivanze bivamo imbaraga zitinda kwiyongera kubushyuhe bwinshi hamwe no kurwanya umunaniro ukabije wumuriro, bikwiranye nigihe kirekire - igihe kinini - ubushyuhe bwikigihe cyakazi;

Ikirenga: Irashobora gutabwa mubice bigoye - bitarinze gutunganywa nyuma, kugabanya umusaruro nigiciro cyo gukora;

Ibyiza Byuzuye Byubukanishi: Ifite imbaraga nyinshi na plastike, irashobora kuba yujuje ibyangombwa bisabwa mu gihe ihanganye n'ubushyuhe bwo hejuru, kandi ntibishobora kuvunika;

Kurwanya Ruswa: Kurwanya alkaline kandi yoroheje ya okiside itera, ihuza nibisabwa na ruswa yinganda nyinshi - ibidukikije.

2. Gusaba Ingingo z'ingenzi

Ibi bikoresho niibyuma, cyane cyane ikoreshwa mubice, ntabwo ari imyirondoro yazengurutswe nk'isahani n'utubari;

Kurwanya ruswa ikomeye (aside ikomeye, umunyu mwinshi, okiside ikomeye) ni rusange. Kubintu nkibi byakazi, imiti irwanya - ishobora kwangirika cyangwa irenga - ibikoresho byo mu rwego rwo hejuru bigomba gusimburwa;

Nubwo ubushyuhe bwayo - bwo kurwanya ubushyuhe bwiza cyane, muri ultra - ahantu h’ubushyuhe bwo hejuru hejuru ya dogere 900, imiterere ya firime ya oxyde yo hejuru igomba kugenzurwa buri gihe kugirango birinde kwangirika kwa matrix;

Nyuma yo gutara, ubushyuhe bwayo - imiterere yubushyuhe hamwe nubushyuhe bwumuriro birashobora kurushaho kunozwa binyuze muburyo bwo kuvura ubushyuhe nko kuvura igisubizo no kuvura gusaza.
