YG vs YN Cement ya Carbide: Itandukaniro ryingenzi ryimashini zinganda

1. Umwanya wibanze: Itandukaniro ryibanze hagati ya YG na YN

(A) Ibigize Byerekanwe na Nomenclature

• YG Series (WC-Co Carbides): Yubatswe kuri tungsten karbide (WC) nkicyiciro gikomeye hamwe na cobalt (Co) nka binder (urugero, YG8 irimo 8% Co), yagenewegukomera no gukoresha neza.
• YN Urukurikirane (TiC-ishingiye kuri Carbide): Ubwoko bubiri burahari: bushingiye kuri TiC (urugero, YN10 hamwe na Ni-Mo binder) cyangwa WC-TiC ikomatanya (urugero, YN6 hamwe na Co-Ni binder), byashyizwe kurigukomera cyane, kurwanya ubushyuhe, hamwe nibidukikije bidasanzwe.

(B) Urubanza rwambere rwo gusaba Urubanza

• YG iruta ibikoresho byoroshye n'ingaruka zerekana: Nibyiza kubicyuma, ibyuma bidafite fer (aluminium, umuringa), hamwe nibisabwa bisaba guhangana ningaruka nko gucukura geologiya na kashe bipfa.
• YN kabuhariwe mubikoresho bikomeye nibidukikije bikabije: Byuzuye kurangiza ibyuma bya karubone / kuzimya ibyuma, ubushyuhe bwo hejuru bwangiza ibidukikije (imiti, ikirere), hamwe nibikoresho bya elegitoroniki bitari magnetiki.

2. Kugereranya-Byimbitse Kugereranya: Kuva Mubihimbano Kuri Imikorere Kuri Porogaramu

(A) Ibigize: Kode yimiti ya Binders hamwe nicyiciro gikomeye

1. YG Urukurikirane: Nyampinga ukomeye wa Sisitemu Yera ya WC-Co

• Inzira nyamukuru: 85% -94% WC, 6% -15% Co (urugero, YG15 hamwe na 15% Co), nta titanium (Ti), ubucucike 13.9-14.8g / cm³ (amavuta aremereye).
• Ibyiza bya Microstructural: Ductility ya Co itanga imbaraga zidasanzwe (YG8 igera kuri 2300MPa). Urwego rwiza-ingano (urugero, YG3X) byongera ubukana kuri 92HRA mugutunganya ibinyampeke bya WC, kuringaniza imyambarire no kwihanganira.

2. YN Urukurikirane: Imikorere Iterambere rya TiC-ishingiye kuri Alloys

• TiC ishingiye ku mavuta (urugero, YN10): Kurenga 90% TiC, 10% Ni-Mo binder, ubucucike 5.5-6.0g / cm³ gusa, ubukana 92-95HRA, gukomeza ubushobozi bwo guca kuri 1200 ℃ hamwe no kurwanya cyane kwambara.
• WC-TiC Igizwe (urugero, YN6).

(B) Itandukaniro ryimikorere: Impinduka zingenzi zo Gukora Imikorere nubuzima bwigikoresho

1. Gukomera no Kwambara Kurwanya: YN Ishiraho Ibipimo byo Gukora neza

• Ubukomezi bwa YG: 89-91HRA (YG3X ingano nziza igera kuri 92HRA), ibereye kwambara hejuru mugukora ibyuma bikarishye.
• YN isukuye ya TiC ishingiye: 91-95HRA, kwagura ubuzima bwibikoresho inshuro 3-5 ugereranije na YG mugihe utunganya ibyuma bizimye (60HRC). Coefficient yo hasi yo hasi (0.3 vs YG's 0.5) igabanya ibyangiritse byakazi.

2. Gukomera no Kurwanya Ingaruka: YG Iyobora Gukata Rimwe na rimwe

• Cobalt ya YG itanga ubukana bwa 4-8J / cm² (YG20C kuri 6J / cm²), bikagabanya ibyago byo gukata 40% mugukata rimwe na rimwe (urugero, gusya ibyuma cyangwa ibihimbano).
• YN isukuye ya TiC ifite ubukana buke (1500MPa flexural strength), ariko YN15 ikomatanya yongerera imbaraga imbaraga za 2000MPa wongeyeho WC na Co, byujuje ibyifuzo birwanya anti-vibrasiya kugirango umutwaro uremereye uhoraho.

3. Kurwanya Ubushyuhe no Guhindura Imiti: YN Abapayiniya Imashini Yubushyuhe Bwinshi

• YG itukura: 600-800 ℃, aho Co ihuza byoroshye nicyuma cya ferrous, bigatuma ibikoresho byubaka.
• YN yuzuye TiC ishingiye kuri 1000-1300 ℃, hamwe na Ni-Mo binder irwanya okiside. Kuba TiC idafitanye isano nicyuma itezimbere imikorere ya anti-adhesion ku kigero cya 60% mugutunganya ibyuma bidafite ingese, bikwiriye gukata byihuse (umuvuduko wumurongo ≥200m / min).

:

1. Urutonde rwa YG: Guhitamo Ikiguzi-Cyiza Cyuma Cyuma Cyimashini Rusange

• Shira ibyuma: YG6 / YG8 kugirango uhindurwe bikabije byicyuma cyumukara (ibiryo> 0.3mm / r); YG15 yo guhagarika gusya ibyuma byangirika, bizamura ingaruka zingaruka 30%.
• Gukora ibicuruzwa: Amanota yo hejuru-Y nka YG20C (20% Co) kumutwe ukonje apfa, hamwe na 2000MPa guhagarika umutima kandi bikamara 5x kurenza HSS.
• Gucukura geologiya: YG11C gucukura amenyo bigabanya gucika ku rutare ku kigero cya 25% mu gucukura gaze ya shale, bizamura imikorere yo gucukura 15%.

2. YN Urukurikirane: Umuyobozi Uyobora Imikorere yo Kurangiza Ibyuma nibidukikije bidasanzwe

• Imashini itomoye yicyuma kizimye: YN10 ibikoresho byo guhindura birangiza 58HRC ifite ibyuma kuri 150m / min, igera kubutaka bwa Ra0.4μm, yegera gusya neza.
• Ibice birwanya ruswa mu nganda zikora imiti: Impeta ya YN6 yerekana igipimo cya ruswa ya 0.05mm / mwaka gusa muri 10% acide hydrochloric, ikamara 3x kurenza kashe ya YG.
• Ibikoresho bya elegitoroniki bitari Magnetique: YN15 idafite magnetique (permeability <1.0001) kubikoresho bya MRI, wirinda kwivanga kwa magneti hamwe nikosa risobanutse <0.001mm.

3. Igitabo cyo Guhitamo: Intambwe 4 Kuri Ibikoresho Byiza

(A) Intambwe ya 1: Sobanura Ibikoresho Byakazi

• Shira icyuma / aluminium / umuringa / utari ibyumaShyira imbere YG (YG8 kugirango ikoreshwe neza, YG6X ingano nziza yo kurangiza).
• Ibyuma bya karubone / ibyuma bivanze / ibyuma byazimye / ibyuma bidafite ingeseShyira imbere YN (Yera ya TiC ishingiye kuri YN10 kugirango irangire byihuse, ikomatanya YN6 kugirango ikoreshwe muri rusange).

(B) Intambwe ya 2: Suzuma uburyo bwo gutema

• Gukata rimwe na rimwe / gukora imirimo iremereye: YG ikurikirana (YG15's 2250MPa imbaraga zingirakamaro zitanga 40% birwanya ingaruka zirenze YN).
• Gukomeza kurangiza / gukata byihuse: Urukurikirane rwa YN (YN10 irwanya ubushyuhe hejuru ya 50%, umuvuduko wo kugabanya ugera kuri 250m / min).

(C) Intambwe ya 3: Reba Ibisabwa Ibidukikije

• Ubushyuhe bwo hejuru / bubora / butari magnetiki ibidukikije: YN ikurikirana (YN15 irwanya 600 ℃ + acide / alkalis; YN6 yujuje ibyifuzo bitari magnetiki kuri electronics).
• Ibidukikije bisanzwe / ibiciro-byoroshye: YG ikurikirana (20% -30% igiciro gito ugereranije na YN, nibyiza kugura byinshi).

(D) Intambwe ya 4: Reba amanota asanzwe yo kugereranya Imbonerahamwe

4. Umwanzuro: Hitamo Carbide iburyo ya sima kugirango uzamure imikorere yimashini

YG na YN ntabwo barwanya guhitamo ahubwo "ibikoresho byuzuye" muburyo butandukanye bwo gutunganya: YG ikubiyemo imashini rusange hamwe nigiciro cyinshi kandi gikomeye, mugihe YN icamo icyuho mubikoresho bigoye hamwe nibidukikije bikabije hamwe nibikorwa byiza. Niba ari umusaruro uhamye wo gutunganya ibyuma, gushakisha neza kurangiza ibyuma byazimye, cyangwa kuramba igihe kirekire mubidukikije byangirika, gusobanura ibikenewe no guhuza ibihimbano-imikorere-ya-logique yerekana agaciro ka karbide.

Twandikire nonahakubona ibisubizo byumwuga byatoranijwe hanyuma ureke YG / YN ya sima ya karbide ihinduka imbaraga zawe zingenzi zo kunoza imikorere yimashini!
