20# wela ʻōwili pepa kila

(1) Nā hiʻohiʻona ʻO ke kila no ke kila kalapona haʻahaʻa haʻahaʻa kiʻekiʻe, hoʻokuʻu ʻia ke anuanu, carburized a paʻakikī. ʻO ke kila ka ikaika haʻahaʻa, ka paʻakikī maikaʻi, ka plasticity a me ka weldability. ʻO ka ikaika tensile ʻo 253-500MPa, a ʻo ka elongation ʻo ≥24%.
ʻO nā waiwai o 20 keʻano like me ka 15 kila, akāʻoi aʻe ka ikaika. Hoʻohana: kūpono no ka hana ʻana i nā ʻāpana carburizing liʻiliʻi a me ka carbonitriding ʻaʻole koʻikoʻi no ke kūkulu ʻana i nā kaʻa, nā tractors a me nā mīkini hana maʻamau, e like me nā kāmaʻa lima lima, nā lever shaft, nā pahu pahu wikiwiki, ka hoʻouna ʻana i nā mīkini passive a me nā Camshafts ma nā trak, nā kumu hoʻohālikelike hoʻokuʻu, nā mea hoʻohālikelike i loko a me waho, etc.; hoʻohana ʻia no ka hana ʻana i nā ʻāpana mechanical like ʻole i koʻikoʻi akā koi i ka paʻakikī kiʻekiʻe ma lalo o nā kūlana wela a i ʻole maʻamau; i loko o ka mīkini kaumaha a me ka medium-sized machinery manufacturing Medium, e like me forged a paʻi paʻi koʻokoʻo, shackles, levers, lima lima, clamps, etc. e hana ana i ka media non-corrosive me ke kaomi o ≤6N/square a me ka mahana o ≤450 ℃; hoʻohana ʻia e hana i nā keʻa ma nā alahao, nā locomotives a me nā kaʻa.
Hiki i ka Normalizing ke hoʻoikaika i ka spheroidization o ke kila, hoʻomaʻemaʻe i ka proeutectoid ferrite nui, a hoʻomaikaʻi i ka hana ʻoki ʻana o ka blank ma lalo o 160HBS.
ʻO ke ala kaʻina o nā ʻāpana make kila: blanking → forging die blank→ annealing → mechanical rough machining → cold extrusion molding → recrystallization annealing → mechanical hoʻopau → carburizing → quenching, tempering → wili a polishing → hui.
(2) Kūlana hoʻouna a me ka paʻakikī Kūlana ʻole, paʻakikī ≤156HBS.

ʻO ka hui kemika o ke kila JB/T 6057-92 (ka hapa nui, %)

Nā waiwai mīkini
(5) ʻO ka mahana hoʻololi o ka pae (kokoke waiwai) Ac1=735℃, Ac3=855℃, Ar3=835℃, Ar1=680℃
(6) Normalizing kikoʻī ʻO ka mahana he 920 ~ 950 ℃, a hoʻomaʻamaʻa ka umu. ʻO 131 ~ 156HBS ka paʻakikī.
(7) Nā kikoʻī no ka hoʻomaʻemaʻe ʻana i ka mālama ʻana i nā blanks kaomi ʻana ʻO ka mahana he 700 ~ 720 ℃, ka manawa paʻa ʻo 8 ~ 15h, a ʻo 50 ~ 100 ℃ /h, a hāʻule ka mahana i 550 ~ 600 ℃ me ka umu ahi, a ua hooluolu ka umu.
ʻO ka paʻakikī ma mua o ka mālama ʻana ʻo ≤143HBS, a ʻo ka paʻakikī ma hope o ka palupalu ʻana ʻo ≤131HBS.
(8) Hōʻike hōʻike Quenching Temperature 910 ℃ ± 10 ℃, hoʻoluʻu me 10% NaCl brine.
(9) Ana i ka ikaika hua fy=245Mpa, elastic modulus E=206Gpa, Poisson ratio ν=0.3.
(10) ʻO ka ikaika shear ʻo 275 ~ 392MPa, ʻo ka ikaika tensile ʻo 253 ~ 500MPa, ʻo ka ikaika hua ʻo 275MPa, a ʻo ka elongation he 25%.
(11) ʻO 600-650 degere wale nō ka mahana annealing, a ʻo ka manawa paʻa he 1-2h.

ʻO kā mākou mau lawelawe o kā mākou pā puni:

1. Inā loaʻa iā ʻoe kekahi pilikia maikaʻi ma hope o ka loaʻa ʻana o ka waiwai, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou, e hoʻokele a pane mākou iā ʻoe i loko o 12 hola.

2. He hale hana mākou i ka SS Round bar, ka mana hana maikaʻi loa, ka mana maikaʻi loa, ka lawelawe maikaʻi loa.

3. Nānā ʻia e ka Inspection Institution o SGS a i ʻole ISO.

4.100% QC nānā ma mua o Shippment.

Inā he nīnau kāu iā Plesse e hoʻokaʻaʻike mai iā mākou i ka manawa.
