Fasteners, bearings, gears, springs, pwm thiab tuag yog qhov tseem ceeb ntawm kev tsim khoom, uas cuam tshuam ncaj qha rau qhov zoo thiab kev ntseeg siab ntawm cov tshuab. Hlau thiab hlau cov ntaub ntawv yog cov khoom siv hauv paus rau kev tsim cov khoom siv hauv paus, tam sim no, cov khoom tsim tawm txhua xyoo ntawm cov hlau rau cov khoom siv hauv Suav teb yog kwv yees li 24 lab tonnes, uas yog ib qho loj ntawm ntau yam khoom tshwj xeeb steel. Fasteners, bearings, gears, springs, pwm thiab lwm yam kev pab cuam ib puag ncig yog txawv, qhov zoo ntawm cov khoom yuav tsum tau kuj txawv. Nws tuaj yeem hais tau tias qhov zoo ntawm cov hlau siv hauv cov khoom siv hauv paus txiav txim siab txog qib ntawm cov tshuab tsim khoom, tab sis kuj yog sawv cev rau kev txhim kho tag nrho ntawm cov yam ntxwv tshwj xeeb steel thiab qib.
Fasteners yog hu ua ' mov ntawm kev lag luam', yog daim ntawv thov loj tshaj plaws ntawm cov khoom siv hauv paus. 2023, Tuam Tshoj tus fasteners nrog steel muaj li 12.5 lab tonnes. Hlau rau fasteners npog yuav luag txhua hom hlau, feem ntau suav nrog cov hlau taub hau txias, hlau alloy steel, stainless hlau, cov hlau tsis muaj cua sov, thiab lwm yam., tus qauv lub zog nyob rau hauv thaj tsam ntawm 400 MPa ~ 1200 MPa. Fasteners feem ntau yog tsim los siv cov txheej txheem txias taub hau, uas yuav tsum tau cov hlau kom muaj cov khoom txias txias zoo. Nyob ntawm daim ntawv thov scenario, steel rau fasteners kuj yuav tsum tau tiv taus qaug zog puas tsuaj, ncua kev puas tsuaj, corrosion, siab thiab tsis kub.
Kev sib tw nqi qis rau cov fasteners tau ua rau MnB steel los hloov CrMo steel hauv ntau qhov ntau. Tam sim no, Tuam Tshoj tus qauv (GB/T 3098.1-2010) nyob rau hauv cov fasteners ntawm qib siab tshaj 12.9, mechanical lightweight yuav tsum ntawm 14.9 thiab siab tshaj lub zog fasteners, ntxiv rau cov txheej txheem ntau lawm yuav tsum tau daws, tab sis kuj tseem tsom rau kev ncua kev puas tsuaj thiab qaug zog thiab lwm yam teeb meem.
