YG vs YN Cemented Carbides: Nā ʻokoʻa koʻikoʻi no ka mīkini ʻenehana

1. Ke Kūlana Kūlana: Ka ʻokoʻa kumu ma waena o YG a me YN

(A) Hoʻokumu ʻia e ka Nomenclature

• Huina YG (WC-Co Carbides): Kūkulu ʻia ma luna o ka tungsten carbide (WC) ma ke ʻano paʻakikī me ka cobalt (Co) ma ke ʻano he mea hoʻopili (e laʻa, aia ka YG8 i 8% Co), i hoʻolālā ʻia noʻoʻoleʻa a me ke kumu kūʻai.
• Māhele YN (TiC-Based Carbides): Aia nā ʻano ʻelua: maʻemaʻe TiC-based (e laʻa, YN10 me Ni-Mo binder) a i ʻole WC-TiC composite (e laʻa, YN6 me Co-Ni binder), i hoʻopaʻa ʻia nopaʻakikī kiʻekiʻe, pale wela, a me nā noi kaiapuni kūikawā.

(B) Hoʻoholo Hoʻoholo Hoʻohālikelike Hoʻohana Hoʻomaka

• ʻOi maikaʻi ʻo YG i nā mea palupalu a me nā hiʻohiʻona hopena: He kūpono no ka hao hoʻolei ʻia, nā metala non-ferrous (alumini, keleawe), a me nā noi e koi ana i ka pale ʻana i ka hopena e like me ka hoʻoheheʻe ʻana i ka honua a me ka make ʻana.
• Kūleʻa ʻo YN i nā mea paʻakikī a me nā kaiapuni koʻikoʻi: He kūpono no ka hoʻopau ʻana i ke kila kalapona/ke kila kinai ʻia, nā kaiapuni corrosive wela kiʻekiʻe (kemika, aerospace), a me nā mea uila non-magnetic.

2. Hoʻohālikelike Hohonu: Mai ka Hoʻohui ʻana i ka Hana ʻana i ka Hoʻohana

(A) Hoʻohui: ʻO ke Code Chemical o nā mea hoʻopili a me nā hana paʻakikī

1. ʻO YG Series: ʻO ka Poʻokela Paʻakikī o ka Pūnaehana WC-Co Maʻemaʻe

• Kumu kumu: 85%-94% WC, 6%-15% Co (e laʻa, YG15 me 15% Co), ʻaʻohe titanium (Ti), mānoanoa 13.9-14.8g/cm³ (mea hao kaumaha).
• Pōmaikaʻi Microstructural: Hāʻawi ka Ductility o Co i ka ikaika flexural maikaʻi loa (hiki i ka YG8 i 2300MPa). Hoʻonui ka paʻakikī i ka 92HRA ma o ka hoʻomaʻemaʻe ʻana i nā kīʻaha WC, ka hoʻohālikelike ʻana i ke kūpaʻa ʻaʻahu a me ka pale ʻana i ka ʻōpala.

2. YN Series: Hoʻomaka i ka hana ʻana o nā Alloys Kūʻē TiC

• Nā Alloys Kūlike TiC (e laʻa, YN10): Ma luna o 90% TiC, 10% Ni-Mo binder, density wale nō 5.5-6.0g/cm³, paʻakikī 92-95HRA, e mālama ana i ka hiki ke ʻoki ma 1200 ℃ me ke kūpaʻa kūʻokoʻa i ka lole lua.
• WC-TiC Composite (e laʻa, YN6): 92% WC mana nui, 2% Ni + 6% Co i hoʻohui ʻia, e hoʻohui ana i ka paʻakikī o YG (1800MPa flexural ikaika) a me ka pale ʻino ʻana o YN no nā hiʻohiʻona o ka waikawa / alkali.

(B) Nā ʻokoʻa o ka hana: Nā ʻokoʻa koʻikoʻi no ka maikaʻi o ka mīkini a me ke ola mea hana

1. Paʻa Paʻa a Wear: Hoʻonohonoho ʻo YN i ka Benchmark no ka mīkini pololei

• ʻO YG paʻakikī: 89-91HRA (hiki i ka huaʻai maikaʻi ʻo YG3X i ka 92HRA), kūpono no ka hoʻohana ʻana i ka ʻili i ka mīkini hao hao.
• ʻO YN maʻemaʻe ʻo TiC paʻakikī: 91-95HRA, hoʻolōʻihi i ke ola mea hana 3-5 mau manawa i hoʻohālikelike ʻia me YG i ka wā e hana ai i ke kila kinai (60HRC). ʻO ka helu haʻahaʻa haʻahaʻa (0.3 vs YG's 0.5) e hōʻemi i ka pōʻino wela o ka mea hana.

2. ʻO ka Paʻakikī a me ke kū'ēʻana i ka hopena: YG Leads in Intermittent Cutting

• Hāʻawi ka kobalt o YG i ka paʻakikī o ka hopena o 4-8J/cm² (YG20C ma 6J/cm²), e hōʻemi ana i ka pilikia ʻoki ʻana ma 40% i ka ʻoki ʻana (e laʻa, ka wili ʻana i ka hao a i ʻole nā ​​blank forged).
• ʻO YN maʻemaʻe TiC-based he haʻahaʻa haʻahaʻa (1500MPa flexural ikaika), akā hoʻonui ka YN15 composite i ka ikaika flexural i 2000MPa ma ka hoʻohui ʻana iā WC a me Co, e hālāwai me nā pono anti-vibration no ka ʻoki mau ʻana i ka māmā.

3. Heat Resistance and Chemical Stability: YN Pioneers High-Temperature Machining

• ʻO YG ʻulaʻula paʻakikī: 600-800 ℃, kahi e hoʻopaʻa maʻalahi ai ʻo Co me nā metala ferrous, e hoʻoulu ai i ka ʻaoʻao o ka mea hana.
• ʻO YN maʻemaʻe ʻo TiC e kū i ka 1000-1300 ℃, me ka mea hoʻopaʻa Ni-Mo e kūʻē i ka oxidation. ʻO ka haʻahaʻa haʻahaʻa o TiC no ke kila e hoʻomaikaʻi i ka hana anti-adhesion e 60% i ka mīkini kila kila, kūpono no ka ʻoki kiʻekiʻe (linear speed ≥200m/min).

(C) Nā Manaʻo Noi: ʻO ka "Multiple-Choice" no nā Pono Mīkini Pono

1. YG Series: Cost-Effective Choice for Non-Ferrous Metals and General Machining

• Mkini Hao: YG6/YG8 no ka huli ʻana o ka hao hina hina (feed >0.3mm/r); ʻO YG15 no ka wili ʻana i ka hao ductile, e hoʻomaikaʻi i ka pale ʻana i ka hopena e 30%.
• Hana Mold: Ua make nā māka kiʻekiʻe-Co e like me YG20C (20% Co) no ke poʻo anu, me ke koʻikoʻi compressive >2000MPa a ʻoi aku ka lōʻihi o 5x ma mua o nā poʻo HSS.
• ʻO ka ʻeli ʻāina: ʻO nā niho wili YG11C e hoʻemi i ka haki ʻana o ka pōhaku e 25% i ka ʻili ʻana i ka shale gas, e hoʻonui ana i ka pono o ka drilling e 15%.

2. YN Series: Ke alakaʻi hana no ka hoʻopau kila a me nā kaiapuni kūikawā

• Ka Mīkini Pono o ke kila kinai: YN10 huli mea paahana hoopau 58HRC amo kila ma 150m/min, loaa ili roughness Ra0.4μm, kokoke wili pololei.
• ʻO nā ʻāpana kūʻē i ka corrosion i loko o ka ʻoihana kemika: Hōʻike nā apo sealing YN6 i ka corrosion rate o 0.05mm/makahiki wale nō ma 10% hydrochloric acid, ʻoi aku ka lōʻihi o 3x ma mua o nā sila YG.
• Nā ʻĀpana Uila ʻAʻole Magnetic: YN15 non-magnetic alloy (permeability <1.0001) no nā ʻāpana lako MRI, e pale ana i ka hoʻopili magnetic me ka pololei pololei <0.001mm.

3. Ke alakaʻi koho: 4 mau ʻanuʻu i ka mea ʻoi loa

(A) KaʻAnuʻu 1: Wehewehe i nā Pono Mea Hana Mea Hana

• ʻO ka hao / alumini / keleawe / metala ʻole→ E hoʻokumu i ka YG (YG8 no ka maikaʻi o ke kumu kūʻai, YG6X palaoa maikaʻi no ka hoʻopau ʻana).
• ʻO ke kila kalapona/ke kila kila/ke kila kinai ʻia/ke kila ʻole→ Hoʻokumu i ka YN (YN10 maʻemaʻe TiC no ka hoʻopau wikiwiki, YN6 composite no ka hoʻohana maʻamau.

(B) KaʻAnuʻu 2: E loiloi i nā kūlana ʻoki

• ʻOki ʻoki manawaleʻa / mīkini hana kaumaha: YG moʻo (YG15's 2250MPa flexural ikaika hāʻawi 40% kiʻekiʻe ka hopena kū'ē ma mua o YN).
• Hoʻopau mau / ʻoki wikiwiki kiʻekiʻe: YN series (YN10's heat resistance up 50%, oki wikiwiki a hiki i 250m/min).

(C) KaʻAnuʻu 3: E noʻonoʻo i nā Koina Kaiapuni

• ʻO nā kaiapuni kiʻekiʻe / corrosive / non-magnetic: YN moʻo (YN15 kū'ē i 600 ℃ + acids/alkalis; YN6 halawai me non-magnetic pono no ka uila).
• Kaiapuni maʻamau/koʻikoʻi koʻikoʻi: YG moʻo (20% -30% haʻahaʻa haʻahaʻa ma mua o YN, kūpono no nā kūʻai nui).

(D) KaʻAnuʻu 4: E kuhikuhi i ka papa hoʻohālikelike maʻamau

Ka Papa Hana	Papa Manaʻo	Pono Pono	Hoʻohālikelike Hoʻohālikelike Māmā
ʻO ka huli ʻana i ka hao	YG8	Ke kū'ē i ka hopena + kū'ē kū'ē, ke kumu kūʻai haʻahaʻa	Ke ola o ka mea hana> 8h ma 0.5mm/r hānai
Hoʻopau i ka hoʻohuli ʻana i ke kila pio	YN10	ʻO ka paʻakikī kiʻekiʻe + ke kūpaʻa wela, Ra0.8μm hoʻopau ʻili	Paʻa pololei ma 200m/min
Nā Noho Paʻa Kemimi Kūʻē Kūʻē	YN6	ʻAkika/ʻalkali kūpaʻa + ʻoʻoleʻa waena	ʻO ke ola lawelawe> 2 mau makahiki ma nā wahi corrosive
Make ʻia ke poʻo anu anuanu kiʻekiʻe	YG20C	ʻO ka paʻakikī High-Co, anti-chipping	> 100,000 mau pōʻaiapuni

4. Ka hopena: E koho i ka Carbide Cemented Pono e hoʻokiʻekiʻe i ka maikaʻi o ka mīkini

ʻAʻole kūʻē ʻo YG a me YN i nā koho akā ʻo "nā mea hana pololei" no nā hiʻohiʻona mīkini ʻokoʻa: uhi ʻo YG i ka mīkini maʻamau me ka maikaʻi a me ka paʻakikī, ʻoiai ʻo YN e haki i nā bottlenecks i nā mea paʻakikī a me nā kaiapuni koʻikoʻi me ka hana kiʻekiʻe. ʻO ka hoʻopuka paʻa paha no ka mīkini hao, ka ʻimi pololei ʻana no ka hoʻopau ʻana i ke kila kinai ʻia, a i ʻole ka lōʻihi o ka lōʻihi i nā wahi corrosive, wehewehe pono a me ka hoʻohālikelike ʻana i ka haku mele-hana-noi e hoʻonui i ka waiwai o nā carbide cemented.

E kelepona iā mākou i kēia manawano ka loaʻa ʻana o nā haʻina koho mea ʻoihana a e lilo nā karbides cemented YG/YN i mea ikaika no ka hoʻomaikaʻi ʻana i ka hana mīkini!
