YG vs YN Cemented Carbides: Kusiyana Kwakukulu kwa Industrial Machining

1. Maimidwe Apakati: Kusiyanitsa Kofunikira Pakati pa YG ndi YN

(A) Kupanga Kuwululidwa ndi Nomenclature

• YG Series (WC-Co Carbides): Yomangidwa pa tungsten carbide (WC) ngati gawo lolimba ndi cobalt (Co) monga chomangira (mwachitsanzo, YG8 ili ndi 8% Co), yopangidwirakulimba mtima komanso mtengo wogwira.
• YN Series (TiC-Based Carbides): Mitundu iwiri ilipo: yokhazikika ya TiC (mwachitsanzo, YN10 yokhala ndi zomangira za Ni-Mo) kapena gulu la WC-TiC (mwachitsanzo, YN6 yokhala ndi Co-Ni binder), yokometsedwakuuma kwakukulu, kukana kutentha, ndi ntchito zapadera zachilengedwe.

(B) Chiweruzo Choyambirira Chogwiritsira Ntchito

• YG imapambana muzinthu zofewa komanso zochitika zamphamvu: Zoyenera kuyika chitsulo, zitsulo zopanda chitsulo (aluminiyamu, mkuwa), ndi ntchito zomwe zimafunikira kukana kukhudzidwa monga kubowola kwa geological ndi kupondaponda kufa.
• YN imakhazikika pazida zolimba komanso malo owopsa: Zokwanira kumaliza zitsulo za kaboni / chitsulo chozimitsidwa, malo owononga kwambiri (mankhwala, mlengalenga), ndi zida zamagetsi zomwe si za maginito.

2. Kufanizitsa Kwakuya: Kuchokera Kupangidwe Kwa Magwiridwe mpaka Kugwiritsa Ntchito

(A) Kupanga: The Chemical Code of Binders and Hard Phases

1. YG Series: The Toughness Champion of Pure WC-Co System

• Core Formula: 85% -94% WC, 6% -15% Co (mwachitsanzo, YG15 ndi 15% Co), palibe titaniyamu (Ti), kachulukidwe 13.9-14.8g/cm³ (aloyi wolemera).
• Ubwino wa Microstructural: Ductility of Co imapereka mphamvu zosinthika kwambiri (YG8 ifika 2300MPa). Magiredi ambewu (monga YG3X) amakulitsa kuuma mpaka 92HRA poyenga mbewu za WC, kusanja kukana kuvala ndi kukana kupukuta.

2. YN Series: Kupambana Kwambiri kwa TiC-Based Alloys

• TiC-Based Alloys (monga YN10): Kupitilira 90% TiC, 10% Ni-Mo binder, kachulukidwe kokha 5.5-6.0g/cm³, kuuma 92-95HRA, kukhalabe ndi luso lodula pa 1200 ℃ ndikukana kwambiri kuvala kwa crater.
• WC-TiC Composite (mwachitsanzo, YN6): 92% WC wamkulu, 2% Ni + 6% Co anawonjezera, kuphatikiza kulimba kwa YG (1800MPa flexural mphamvu) ndi kukana kwa dzimbiri kwa YN kwa zochitika zapakatikati za asidi / alkali.

(B) Kusiyana kwa Magwiridwe: Zosintha Zofunika Kwambiri pa Machining Mwachangu ndi Chida Moyo

1. Kuuma ndi Kukaniza Kuvala: YN Imayika Benchmark ya Precision Machining

• YG kuuma: 89-91HRA (YG3X fine-grain ikufika ku 92HRA), yoyenera kuvala pamwamba pamakina opangira chitsulo.
• YN kuuma kochokera ku TiC: 91-95HRA, kukulitsa moyo wa chida 3-5 nthawi poyerekeza ndi YG pakumata chitsulo chozimitsidwa (60HRC). Kugundana kocheperako (0.3 vs YG's 0.5) kumachepetsa kuwonongeka kwamafuta.

2. Kulimba ndi Kukaniza Kwamphamvu: YG Imatsogolera Kudula Kwapakatikati

• Cobalt ya YG imapereka mphamvu zolimba za 4-8J/cm² (YG20C pa 6J/cm²), kuchepetsa chiwopsezo cha kutsetsereka ndi 40% pakudula pakapita nthawi (mwachitsanzo, chitsulo choponyera mphero kapena zosasoweka).
• YN yoyera ya TiC-based imakhala ndi kulimba kocheperako (1500MPa flexural mphamvu), koma gulu la YN15 limawonjezera mphamvu zosunthika mpaka 2000MPa powonjezera WC ndi Co, kukwaniritsa zosowa zotsutsana ndi kugwedezeka pakudulira kosalekeza.

3. Kutsutsana kwa Kutentha ndi Kukhazikika kwa Chemical: YN Pioneers High-Temperature Machining

• YG kuuma kofiira: 600-800 ℃, pomwe Co amalumikizana mosavuta ndi zitsulo zachitsulo, zomwe zimapangitsa kuti zida zimange m'mphepete.
• YN koyera TiC-based kupirira 1000-1300 ℃, ndi Ni-Mo binder kukana makutidwe ndi okosijeni. Kugwirizana kochepa kwa TiC pazitsulo kumapangitsa kuti ntchito yotsutsa-adhesion ikhale ndi 60% muzitsulo zosapanga dzimbiri, zoyenera kudula mofulumira (liwiro la mzere ≥200m / min).

(C) Zochitika Zogwiritsira Ntchito: "Kusankha Kwambiri" kwa Zosowa Zokonzekera Zolondola

1. YG Series: Kusankha Kotsika mtengo kwa Zitsulo Zopanda Ferrous ndi Machining General

• Cast Iron Machining: YG6/YG8 pakutembenuza movutikira kwachitsulo chotuwa (chakudya> 0.3mm/r); YG15 yosokoneza mphero yachitsulo cha ductile, kupititsa patsogolo kukana ndi 30%.
• Kupanga Nkhungu: High-Co magiredi monga YG20C (20% Co) pamutu wozizira amafa, kupirira> 2000MPa kupsinjika kwapang'onopang'ono komanso kukhalitsa 5x motalika kuposa nkhungu za HSS.
• Kubowola kwa Geological: Mano akubowola a YG11C amachepetsa kusweka kwa miyala ndi 25% pochotsa gasi wa shale, kupititsa patsogolo kubowola bwino ndi 15%.

2. Mndandanda wa YN: Mtsogoleri Wogwira Ntchito Pakumaliza Zitsulo ndi Malo Apadera

• Precision Machining a Zitsulo Zozimitsidwa: YN10 kutembenuza zida mapeto 58HRC kubala zitsulo pa 150m/mphindi, kukwaniritsa roughness pamwamba Ra0.4μm, akuyandikira akupera mwatsatanetsatane.
• Zigawo Zosagwirizana ndi Kuwonongeka kwa Chemical Viwanda: mphete zosindikizira za YN6 zimawonetsa kuchuluka kwa dzimbiri kwa 0.05mm / chaka mu 10% hydrochloric acid, yotalika 3x kuposa zisindikizo za YG.
• Zida Zamagetsi Zopanda Magnetic: YN15 non-magnetic alloy (permeability <1.0001) ya zida za MRI, kupewa kusokoneza maginito ndi zolakwika zolondola <0.001mm.

3. Maupangiri Osankhira: Njira 4 Zopangira Zinthu Zabwino

(A) Khwerero 1: Tanthauzirani Katundu Wazinthu Zogwirira Ntchito

• Ponyani chitsulo/aluminium/copper/non-zitsulo→ Ikani patsogolo YG (YG8 kuti ikhale yotsika mtengo, YG6X mbewu yabwino kuti mumalize).
• Mpweya zitsulo / aloyi chitsulo / kuzimitsidwa zitsulo / zitsulo zosapanga dzimbiri→ Ikani patsogolo YN (YN10 yeniyeni yochokera ku TiC kuti mumalize kuthamanga kwambiri, yophatikizika YN6 kuti mugwiritse ntchito wamba).

(B) Khwerero 2: Unikani Mikhalidwe Yodula

• Kudula kwapakatikati/kulemera-ntchito makina: Mndandanda wa YG (YG15's 2250MPa flexural mphamvu imapereka 40% kukana kwakukulu kuposa YN).
• Kumaliza kopitilira / kudula kothamanga kwambiri: YN mndandanda (YN10 kutentha kukana mpaka 50%, kudula liwiro kufika 250m/min).

(C) Gawo 3: Ganizirani Zofuna Zachilengedwe

• Malo otentha kwambiri / owononga / osagwiritsa ntchito maginito: YN mndandanda (YN15 amatsutsa 600 ℃ + zidulo / alkalis; YN6 imakwaniritsa zosowa zopanda maginito zamagetsi).
• Madera okhazikika/osakwera mtengo: Mndandanda wa YG (20% -30% mtengo wotsika kuposa YN, woyenera kugula zambiri).

(D) Gawo 4: Reference Typical Grades Comparison Table

Ntchito Scenario	Gulu lovomerezeka	Ubwino Wachikulu	Kuyerekeza Kuchita Bwino kwa Machining
Kutembenuza Moyipa kwa Iron	YG8	Kukana kwamphamvu + kukana kuvala, mtengo wotsika	Moyo wa chida> 8h pa 0.5mm/r feed
Malizani Kutembenuza Chitsulo Chozimitsidwa	YN10	Kuuma kwakukulu + kukana kutentha, Ra0.8μm pamwamba kumaliza	Kukhazikika kokhazikika pa 200m / min
Mipando Yolimbana ndi Kuwonongeka kwa Chemical Valve	YN6	Acid/alkali resistance + kulimba kwapakatikati	Moyo wothandizira> Zaka 2 m'malo owononga
Mutu Wozizira Kwambiri Ufa	YG20C	High-Co kulimba, anti-chipping	> 100,000 masitampu kuzungulira

4. Kutsiliza: Sankhani Carbide Yoyenera Simenti Kuti Mukweze Kuchita Bwino kwa Machining

YG ndi YN sizosankha zotsutsana koma "zida zolondola" zamakina osiyanasiyana: YG imaphimba makina osavuta komanso olimba, pomwe YN imaphwanya zopinga muzinthu zovuta komanso malo owopsa omwe amagwira ntchito kwambiri. Kaya ndi yokhazikika pamakina achitsulo, kufunafuna kumalizidwa bwino kwachitsulo chozimitsidwa, kapena kulimba kwanthawi yayitali m'malo owononga, kuwunikira zosoweka ndi kufananiza kagwiridwe ka ntchito kumakulitsa kufunikira kwa ma carbides omangidwa.

Lumikizanani nafe tsopanokuti mupeze mayankho osankhidwa mwaukadaulo ndikulola ma carbides olimba a YG/YN akhale mphamvu yanu yayikulu pakuwongolera makina!
