Txuj kev txhim kho Cov naj npawb ntsej muag Coj Bolts yog qhov tseem ceeb hauv lub neej txhua hnub thiab kev tsim khoom. Siab Riveting Ntsuas Ntu Cov Kev Ceev Bolts tseem muaj lub npe hu ua mov nplej. Qee qhov chaw muaj cov haujlwm tseem ceeb hauv kev lag luam. Tsuav yog muaj kev lag luam hauv lub ntiaj teb, qhov tseem ceeb ntawm cov fasteners tseem ceeb heev.
Txheem cov pob ntawm cov txiv kab nuv ntses Ntsuas Bolts nquag siv cov khoom siv raws li lub zog ntawm cov txiv ntseej ntsia liaj thawm bolts siv ntau cov ntaub ntawv, qhov tam sim no tus qauv ntawm lub khw tsuas yog carbon hlau, stainless hlau, tooj liab peb cov ntaub ntawv. Cov xov tooj me me nram qab no yuav qhia rau koj txog cov khoom siv raw cov ntaub qhwv raw, thiab cia siab tias yuav pab tau txhua tus.
Carbon steel yog ib qho hlau-hlau alloy nrog cov ntsiab lus qis WC ntawm tsawg tshaj 2.11%. Kuj hu ua carbon steel. Nws feem ntau muaj ib qho me me ntawm silicon, manganese, sulfur thiab phosphorus. Feem ntau cov pa hlau, lub siab dua cov ntsiab lus ntawm lub cev, qhov ntau dua qhov nyuaj thiab siab zog zog, tab sis qhov qis dua qhov yas.
(1) Carbon steel tau muab faib ua peb pawg raws li lub hom phiaj: carbon cov hlau, cov pa roj carbon thiab cov cav ntoo ua dawb. Carbon steel hlau faib ua ob hom: tshuab steel thiab tshuab ua los ua hlau.
(2) Raws li lub smelting txoj kev, nws yuav muab faib ua qhib hearth hlau thiab converter hlau;
(3) Kev Deoxidation txoj kev yuav muab faib ua lub pob hlau (F), tua cov hlau (Z), ib nrab ntawm cov hlau kheej (b) thiab tshwj xeeb raug tua steel (TZ);
(4) Carbon steel tau muab cais ua cov pa carbon tsawg (WC ≤ 0.25%), nruab nrab carbon steel (WC 0.25% -0.6%) thiab cov pa carbon ntau (WC> 0.6%) ntawd cov ntsiab lus carbon;
(5) Raws li qhov zoo ntawm cov hlau, carbon cov hlau yuav muab faib ua ntau hom carbon (ntau dua phosphorus thiab sulfur cov ntsiab lus), cov pa roj carbon tsawg (qis phosphorus thiab sulfur cov ntsiab lus) thiab high-grade hlau (qis phosphorus thiab sulfur cov ntsiab lus ). ) thiab hwm qib steel.
Carbon steel: Peb paub qhov txawv ntawm cov cua uas qis, cov pa roj carbon nrab thiab cov pa loj, thiab cov hlau hlau los ntawm carbon cov ntsiab lus hauv cov hlau.
1. Qis tshaj carbon steel C% ≤ 0.25% Domestically paub li A3 hlau. Yeej paub tias txawv teb chaws li 1008,1015,1018,1022 thiab hais txog. Nws yog tsuas yog siv rau cov khoom uas tsis muaj kev tsis txaus siab xws li 4.8 bolts, 4 ceev, thiab me me screws. (Faj seeb: Lub tshuab drilling yog ua los ntawm 1022 khoom)
Txiv Ntseej Kem Screws Feem ntau siv 1008 1006 nyoos khoom, SAE1008 yog lub koom haum American American Automotive Engineers, 10 nruab nrab Mn tsawg tshaj li 1%, thiab 08 yog cov ntsiab lus ntawm cov pa roj carbon; qhov sib txawv ntawm qhov sib txawv ntawm 1008 thiab 1006 yog qhov txawv hauv cov ntsiab lus. SAE yog lub tebchaws United States Steel Numbering.
Raws li cov ntsiab lus ntawm cov lus nug uas twb muaj lawm, lub ntsiab sib txawv ntawm cov tshuaj chemical ntawm 1006 thiab 1008 yog:
a. Cov ntsiab lus carbon-carbon tsis yog: 1006 nrog C tsawg tshaj 0.08 thiab 1008 tsawg dua 0.10
b. Cov tsis muaj manganese (Mn) cov ntsiab lus: 1006 nrog Mn tsawg dua 0.45 thiab 1008 tsawg dua 0.50
2. Nruab nrab carbon steel 0.25% <> ≤ 0.45% Domestically hu ua No. 35, No. 45 steel, txawv teb chaws feem ntau hu ua 1035, CH38F, 1039, 40ACR thiab hais txog. Feem ntau yog siv rau qib 8 qib, 8.8 bolts, thiab 8.8 qib ntawm cov khoom hexagonal.
3, siab carbon steel C%> 0.45%. Lub khw tsis tshua siv.
4, hlau hlau: Cov pa roj carbon alloy ntsiab ntxiv rau kom qee yam tshwj xeeb ntawm cov hlau: 35,40 chromium molybdenum, SCM435, 10B38.
