1. ʻO ka hoʻolauna pōkole o ka pā anuanu maʻamau

He huahana ia i loaʻa ma ka paʻi anu o nā pepa wela. Ma muli o ka ʻōwili anuanu multi-pass, ʻoi aku ka maikaʻi o kona ʻili ma mua o ka pepa wela, a ma hope o ka mālama ʻana i ka wela, hiki ke loaʻa nā waiwai mechanical maikaʻi.

1. Ka hoʻokaʻawale ʻana o ka hoʻohana ʻana i nā papa i ʻōwili ʻia maʻamau

E like me nā pono like ʻole o nā ʻoihana hana, hoʻokaʻawale pinepine ʻia nā lau i ʻōwili ʻia i:

ʻO ka pepa ʻōwili anu maʻamau i hoʻohana ʻia, ka pepa i ʻōwili ʻia i ke anu, ka huki hohonu, ke kaha kiʻi hohonu a me ka pepa ʻōwili anu-hohonu-hohonu,

Hāʻawi maʻamau ʻia i loko o nā coils a me nā pā pālahalaha, hōʻike ʻia ka mānoanoa ma nā millimeters,

ʻO ka laulā maʻamau: 1000mm a me 1250mm, a ʻo ka lōʻihi he 2000mm a me 2500mm.

2. ʻO ka papa o ka pā anu-wili maʻamau

ʻO nā māka maʻamau:

Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, etc.;

ST12:

Hōʻike ʻia ma ke ʻano he kila kila maʻamau, ʻano like ke ʻano me ka helu Q195, SPCC, a me DC01;

ST13/14:

ʻO ke kila kila i hōʻike ʻia ma ke ʻano he stamping grade ʻo ia ka mea like me nā mea o nā māka 08AL, SPCD, DC03/04;

ST15/16:

ʻO ke kila kila i hōʻike ʻia ma ke ʻano he stamping grade ʻo ia ka mea like me nā mea o nā māka 08AL, SPCE, SPCEN, DC05/06.

3. ʻO ke ʻano o ka hōʻike ʻana i ka pae a me ka nui o nā papa ʻōwili maʻamau

No ka laʻana, ST12 i hana ʻia e Taishan Industrial Development Group Iron and Steel Co., Ltd., 1*1250*2500/C, i hōʻike ʻia e like me: grade ST12 maʻamau pā anu, ʻo 1mm ka mānoanoa, 1250mm ka laulā, 2500mm a i ʻole C coil ka lōʻihi. .

Hoʻopili ʻia ka hiʻohiʻona me ka ʻili hao keʻokeʻo, a ʻo nā ʻano mīkini ka mea maʻamau a me nā pae kila kumu, hiki ke hoʻohana wale ʻia no ka kuʻi ʻana a me ka hoʻokumu ʻana, ʻaʻole no ka hoʻopaʻa ʻana. Hoʻohana ʻia no ka nahu mechanical,

No ka laʻana, ka pūpū o ka pahu hau, ka pahu wahie o ke kaʻa, etc.

Hoʻohana ʻia nā huahana ma luna o ST13 i nā ʻoihana e koi ana i ke kaha kiʻi hohonu, e like me ka hana ʻana i nā kaʻa, nā pahu wahie no nā ʻenekini diesel, a me nā mea ʻē aʻe.

ʻO ka ʻokoʻa ma waena o ST12 a me SPCC: Ua aneane like nā ʻano mechanical o nā huahana ʻelua, akā ʻokoʻa ke ʻano hoʻihoʻi. ʻOi aku ka ikaika o nā waiwai tensile o ka ST12 ma mua o ka SPCC.

ʻO ke ʻano mea maʻamau ʻo Japanese JIS

SPCC—S 'o ia ho'i ke kila (Steel), P 'o ia ka pā (Plate), C 'o ia ke anu (Cold), C 'o ia ho'i ka 'oihana (Kalepa), 'o ia ka ma'amau o Iapana JIS.

Inā pono ʻoe e hōʻoia i ka ikaika tensile, e hoʻohui iā T ma ka hope o ka papa, ʻo ia hoʻi: SPCCT.

SPCD—e hōʻike ana i ka pepa kila kalapona i ʻōwili ʻia a me ke kaula no ke kaha ʻana, ua like ia me ko Kina 08AL (13237) kila kila kiʻekiʻe.

SPCE—E hōʻike ana i ka pepa kila kalapona ʻōwili anuanu no ke kaha kiʻi hohonu, ua like ia me ko Kina 08AL (5213) kila kiʻi hohonu.

Inā koi ʻia ka manawa kūpono ʻole, e hoʻohui i ka N ma ka hope o ka papa e lilo i SPCEN.

ʻO ka pepa kila kalapona i hoʻopaʻa ʻia i ka anu a me ke kaula kila hoʻopaʻa a me ke code tempering: ʻo ka mokuʻāina i hoʻopili ʻia ʻo A, ʻo ka hoʻopiʻi maʻamau a me ka hoʻoulu ʻana ʻo S, 1/8 ka paʻakikī he 8, 1/4 ka paʻakikī he 4, 1/2 ka paʻakikī ʻo 2, piha ka paʻakikī. 1. Ka helu hoʻoponopono o ka ʻili: D no ka ʻōwili ʻana i ka pau ʻana, B no ka ʻōwili ʻana o ka ʻālohilohi.

No ka laʻana, hōʻike ʻia ʻo SPCC-SD i kahi maʻamau i hoʻopaʻa ʻia a hoʻopaʻa ʻia, hoʻopau matte i ʻōwili ʻia ma ke kumu maʻamau.

ʻO kekahi laʻana ʻo SPCCT-SB, ʻo ia hoʻi ka hoʻopau ʻana i ka maʻamau a me ka hoʻomaʻamaʻa ʻana, ka hana ʻālohilohi, a me nā pepa kalapona i ʻōwili ʻia i ke anuanu e koi ana i nā waiwai mechanical.

ʻO kahi laʻana ʻē aʻe ʻo SPCC-1D, ʻo ia hoʻi ka paʻa paʻa paʻa paʻa i hoʻopau ʻia i ka pepa kila kalapona i ʻōwili ʻia.

ʻO ke ʻano o ka haʻi ʻana o nā māka kila no nā hale mechanical ʻo ia: S + carbon content + letter code (C, CK), kahi i hōʻike ʻia ai ka ʻike kalapona e ka waiwai waena * 100, ʻo ka leka C ke kalapona, a ʻo ka huapalapala K ke kila carburizing. . No ka laʻana, loaʻa i ka carbon knot coil S20C kahi maʻi kalapona o 0.18-0.23%.

ʻO ka manaʻo maʻamau o Kina GB

Māhele maʻamau i:

Q195, Q215, Q235, Q255, Q275, etc.

ʻO Q ka huaʻōlelo mua o ka pinyin Pākē o ka huaʻōlelo "Qu" ma ka helu o ke kila, a ʻo 195, 215, etc.

Ma ke ʻano o ka haku mele ʻana, nā māka kila kalapona haʻahaʻa:

ʻOi aku ka nui o nā māka o Q195, Q215, Q235, Q255, a me Q275, ʻoi aku ka kiʻekiʻe o ka ʻike kalapona a me ka ʻike manganese, a ʻoi aku ka paʻa o ka plasticity.

2. ʻO ka hoʻolauna pōkole o ka ʻili kila wela (ke kala keʻokeʻo)

Hana ʻia ia me ka ʻili kila wela a i ʻole ka ʻili ʻili anuanu ma ke ʻano he substrate ma o ke kaʻina hana galvanizing wela wela, hiki ke pale i ka ʻili o ka pā kila lahilahi a me ke kaula kila mai ka ʻino a me ka ʻōpala.

Hāʻawi ʻia ka pepa galvanized hot-dip ma ke ʻano he pā pālahalaha ʻehā ma ke ʻoki ʻoki; ua hoʻolako ʻia ka wili wela wela e like me ka ʻōwili ma ka wili ʻana.

Ma muli o nā ʻokoʻa like ʻole i hoʻohana ʻia, hiki ke hoʻokaʻawale ʻia nā ʻāpana kila wela wela i loko o nā coils galvanized sheet hot-rolled a me nā coils galvanized sheet coils, i hoʻohana nui ʻia i ke kūkulu ʻana, nā mea hana home, nā kaʻa, nā ipu, ka halihali a ʻoihana hale. ʻOi aku ka maikaʻi o ke kūkulu hale kila, ka hana kaʻa, ka hana ʻana i ka puka aniani a me nā ʻoihana ʻē aʻe.

1. ʻO nā hiʻohiʻona o ka pale kila wela wela

ʻO ke kūpaʻa corrosion ikaika, maikaʻi ka maikaʻi o ka ʻili, maikaʻi no ka hana hohonu, ʻoihana a me ka hana, etc.

2. Hoʻohālikelike a me nā hōʻailona o nā pale kila galvanized wela

E like me ka hana hana, ua mahele ia i: kumu nui (PT), mechanical interlocking (JY), hohonu kiʻi (SC), super deep drawing aging (CS), and structure (JG);

E like me ke kaumaha o ka papa zinc: ua māhele ʻia ka ʻili o ka zinc maʻemaʻe i: 100/100 (ʻo ke kaumaha o ka papa zinc ma lalo o 100g/m2),

120/120, 200/200, 275/275, 350/350, 450/450, 600/600;

Ua māhele ʻia ka ʻili o ka zinc-hao i: 90/90

(ʻO ke kaumaha o ka zinc-iron alloy layer ma lalo o 90g / m2), 100/100, 120/120, 180/180;

Wahi a ka ʻili o ka ʻili, ua māhele ʻia i: spangle maʻamau Z, spangle liʻiliʻi X, spangle maʻemaʻe GZ, zinc-iron alloy XT;

Ma muli o ka maikaʻi o ka ili, ua māheleʻia i: Group I (I), Group II (II);

Ma muli o ka pololei o ka dimensional, ua māhele ʻia i: ka pololei kiʻekiʻe A, ka pololei maʻamau B;

Wahi a ka mālama ʻana i ka ʻili, ua māhele ʻia i: chromic acid passivation L, oiling Y, chromic acid passivation me ka ʻaila LY.

Pepa kila kila o Taishan Industrial Development Group:

ʻO Taishan Industrial Development Group Phase II hot-dip galvanizing

Hoʻokumu ʻia ka lua o ka lua o ka galvanizing wela o Taishan Industrial Development Group e ka hoʻomau mau ʻana o ke kila anuanu a ʻōwili wela paha ma Unit 2030, a hoʻohana ʻia no nā kumu maʻamau a i ʻole nā ​​​​hana hoʻolālā.

ʻO ka laulā o ka lako no ka lua o ka pae o ka wela wela: mānoanoa (0.3-0.3), ākea (800-1830), lōʻihi (pā 1000-6000, coil i loko anawaena 610) i mm.

Hoʻokaʻawale ʻia ka lua o ka lua e like me ke ʻano o ka ʻili: Z ʻo ia ka spangle maʻamau, N ʻo ia ka zero spangle, X ʻo ia ka spangle liʻiliʻi, a ʻo G ke ʻano o ka spangle maʻemaʻe.

Hoʻokaʻawale ʻia ka papa lua o ka galvanizing wela e like me ka mālama ʻana i ka ʻili: L ʻo ia ka chromic acid passivation, Y ʻo ia ka ʻaila, LY ʻo ia ka chromic acid passivation + oiling.
ʻO ka mea nui e hōʻemi a pale paha i ka ʻōpala keʻokeʻo i ka wā o ka lawe ʻana a i ʻole ka mālama ʻana.
