Kūʻai wela GB Standard Y12 Y20 Alloy Free-machine Steel Round bar

ʻO nā mea i hoʻohui ʻia i ke kila ʻoki manuahi ʻo S, Pb, Ca a me P. ʻO kā lākou mau hana nui penei:
1. Ke kuleana o ka sulfur
Hoʻokumu ka Sulfur i nā MnS inclusions me Mn i ke kila, hiki ke hoʻopau i ka hoʻomau ʻana o ka matrix, e maʻalahi ka haki ʻana i nā ʻāpana, a hoʻemi i ka wahi pili ma waena o nā chips a me ka mea hana. Hiki nō hoʻi i ka Sulfur ke hoʻemi i ka hakakā a pale i ka pili ʻana o nā ʻāpana i ka ʻoki ʻoki. Eia nō naʻe, hiki i ka loaʻa ʻana o ka sulfur ke hana i ke kila wela a palupalu, no laila ua kaupalena ʻia ka ʻike sulfur i ka laulā o w(s)=0.10%~0.30%, a pono e hoʻonui ʻia ka ʻike Mn e like me ia.
2. Ka hana o ke alakai
Hiki i ka hoʻohui Pb ke hoʻomaikaʻi i ka hana ʻoki ʻana o ke kila. No ka mea, ʻaʻole i hoʻoheheʻe ʻia ʻo Pb i loko o ka ferrite i ke kila a ʻaʻole i hoʻokumu i nā pūhui, aia ia i loko o kahi kūlana manuahi a hana i nā ʻāpana maikaʻi (2 ~ 3μm) i hoʻohele like ʻia i ka hoʻolālā matrix. Ke hiki aku ka wela i ka wā o ka ʻoki ʻana i ka helu heheʻe o nā ʻāpana Pb, aia ia i loko o ke ʻano hoʻoheheʻe ʻia a lilo i "lubricant" ma waena o ka mea hana a me nā ʻāpana a ma waena o ka mea hana a me ka ʻili o ka mea hana, e hōʻemi ana i ke kumu friction, ka ka wela o ka mea hana, a me ka lole. ʻO ka nui o ka Pb i hoʻohui ʻia aia ma ka laulā o w(Pb)=0.1%~0.35%.
3. Ka hana o ka calcium
Hiki iā Ca ke hoʻokomo i ka Ca a me Al silicate i loko o ke kila, e pili ana i ka mea hana e hana i kahi kiʻiʻoniʻoni lahilahi, loaʻa ka hopena hoʻohaʻahaʻa friction, a pale i ka ʻaʻahu o ka mea hana. ʻO ka nui o Ca i hoʻohui ʻia ma ke ʻano maʻamau w(Ca)=0.001%~0.005%.
4. Ka hana o ka phosphorus
Hoʻohui ʻia ʻo P i ke kila ʻoki manuahi me ka sulfur e hoʻoheheʻe iā ia i loko o ka ferrite, e hoʻoikaika ai i ka hoʻoikaika a me ka embrittlement e hoʻomaikaʻi i kāna hana ʻoki. I mea e pale ai i ka "ma'i anu", ua kuhikuhi 'ia ka w(P) ≤0.15%.
ʻO ka hoʻohui ʻana i kēia mau mea hiki ke hoʻomaikaʻi i ka maikaʻi o ka ʻili o ka mea hana a hoʻonui i ke ola lawelawe o ka mea hana.

Inā makemake ʻoe i ka ʻike kikoʻī hou aʻe, pono ʻoe e nīnau iā mākou no ka ʻike kikoʻī e pili ana i nā kikoʻī kikoʻī a me ka hoʻohana ʻana i kēia mau pahu kila.

Hoʻohana nui ʻia ke kila ʻoki manuahi no ka hana ʻana i nā mea kani, nā ʻāpana kiaʻi, nā kaʻa, nā mea mīkini a me nā mīkini ʻē aʻe me ke koʻikoʻi liʻiliʻi akā koi koʻikoʻi i ka nui a me ka roughness; ʻO nā ʻāpana maʻamau me nā koi koʻikoʻi e pili ana i ka pololei o ka dimensional a me ka roughness, akā haʻahaʻa haʻahaʻa nā koi i nā waiwai mechanical, e like me nā gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seats and machine screws, plastic molding molds, surgical and dental. nā mea hana ʻokiʻoki, etc.

FAQ

Q: He mea hana ua?

A: ʻAe, he mea hana mākou. Loaʻa iā mākou kā mākou hale hana ponoʻī ma Daqiuzhuang Village, Tianjin City, Kina. Ma waho aʻe, hana pū mākou me nā ʻoihana aupuni he nui, e like me BAOSTEEL, SHOUGANG GROUP, SHAGANG GROUP, etc.

Nīnau: Hiki iaʻu ke loaʻa i kahi kauoha hoʻokolokolo he nui wale nā ​​tona?

A: ʻOiaʻiʻo. Hiki iā mākou ke hoʻouna aku i ka ukana no ʻoe me ka LCL serivece. (Lis container load)

Q: Loaʻa iā ʻoe ka uku kiʻekiʻe?

A: No ke kauoha nui, 30-90 mau lā L / C hiki ke'āpono.

Q: Inā hāʻawi manuahi?

A: Sample free, akā, uku ka mea kūʻai aku i ka ukana.

Q: ʻO ʻoe ka mea hoʻolako gula a hana i ka hōʻoia kālepa?

A: ʻEhiku mau makahiki kā mākou mea kūʻai anu a ʻae i ka hōʻoia kālepa. E hōʻoluʻolu mākou i kā mākou mea kūʻai mahalo ʻia me ko mākou ʻano maikaʻi maikaʻi loa, ke kumukūʻai kūʻai maikaʻi a me ka ʻoihana maikaʻi ma muli o ko mākou ʻoi aku ka loea a ʻoi aku ka paʻakikī a hana i loko. ʻO ke ala kūʻai maikaʻi no ka ʻoihana Kina HRB400 HRB500 Hrb500e Deformed Steel Rebar Round Bar Construction Reinforcing Iron Metal Hot Rolled Round Square Stainless Carbon Steel Flat Corrugated Tmt Bar, Ke nānā mau nei ʻoe i kahi huahana maikaʻi e like me kāu kiʻi hoʻonohonoho maikaʻi ʻoiai e hoʻonui ana i kāu laulima mea? E noʻonoʻo i kā mākou mea kūʻai maikaʻi. ʻO kāu koho e hōʻoia i ka naʻauao!
