"Muaj ntau tus neeg nug tias, 'Dab tsi yoghlau puag ncig hlau"Lub hauv paus tseem ceeb yog 'kev txhawb zog raws li qhov xav tau'," tus thawj coj kev tshaj lij ntawm ZZ Group piav qhia. "Peb cov khoom S55C yog ib qho piv txwv zoo. Ua ib lub chaw tsim khoom siv hlau alloy, peb tsis tsuas yog muab cov qhov loj me - txij li 25mm txog 100mm thiab txawm tias cov lus qhia loj dua - tab sis kuj tseem muaj cov khoom siv daws teeb meem uas tsim rau cov neeg siv khoom siv (xws li kev tsim cov ncej muaj zog siab, iav lossis cov pas nrig txuas). Tshwj xeeb tshaj yog thaum cov neeg siv khoom xav tau cov pas nrig hlau caij nplooj ntoos hlav nrog ob qho tib si elasticity siab thiab kev tiv taus qaug zog, peb kuj tuaj yeem muab cov kev daws teeb meem hlau alloy sib xws."
Los ntawm ib lub zeem muag dav dua,kev tsim khoom ntawm cov hlau alloy round barr tuaj yeem suav hais tias yog ib ceg tshwj xeeb ntawm cov hlau sib xyaw ua ke, hais txog qhov siab elastic txwv thiab kev ua tau zoo tiv thaiv kev so. Nrog ntau tshaj plaub caug xyoo ntawm kev sib sau ua ke hauv kev lag luam hlau thiab kev ua cov hlau, ZZ Group muaj peev xwm txuas cov peev txheej hlau zoo nrog cov kev xav tau tsim khoom qis, kom ntseeg tau tias txawm tias nws yog S55C dav dav lossis tshwj xeebCov Tuav Round Spring Steel, lawv cov tshuaj lom neeg muaj pes tsawg leeg, microstructure thiab cov khoom siv kho tshuab tuaj yeem ua tau raws li cov qauv kev lag luam nruj.
Txij li thaum nws tau tsim tsa hauv Yangpu District, Shanghai thaum ntxov xyoo 1980s, ZZ Group tau loj hlob mus ua ib pawg lag luam loj uas muaj kev lag luam hlau, kev ua khoom thiab kev faib khoom, nrog rau kev nqis peev nyiaj txiag. Nrog rau peev txheej sau npe ntawm 200 lab RMB, nws tau dhau los ua ib lub tuam txhab ua lag luam hauv Suav teb cov khoom siv hlau. Pawg no tau txais txiaj ntsig nrog cov npe xws li "Ib puas Lub Tuam Txhab Txhim Kho Hauv Kev Lag Luam Hlau" thiab "100 Lub Tuam Txhab Ntiag Tug Zoo Tshaj Plaws hauv Shanghai", thiab nws lub koob npe nrov thiab kev muaj peev xwm xa khoom tau muab kev lees paub zoo rau kev muab khoom ruaj khov ntawm ntau yam khoom siv hlau sib xyaw rau cov neeg siv khoom thoob ntiaj teb.
"Peb lub luag haujlwm tsis yog tsuas yog kev lag luam xwb," tus neeg hais lus ntawm pawg neeg tau hais tias. "Raws li lub tuam txhab tsim khoom thiab cov neeg muab kev daws teeb meem ntawm cov hlau sib xyaw ua ke, peb cog lus tias yuav siv peb cov kev pabcuam kev tshaj lij los pab cov neeg siv khoom nkag siab txog cov khoom siv ntawm txhua yam los ntawm cov hlau sib xyaw ua ke, cov hlau carbon mus rau cov hlau caij nplooj ntoos hlav siab heev. Qhov no ua rau lawv xaiv tau cov khoom pheej yig tshaj plaws thiab thaum kawg txhim kho kev sib tw ntawm lawv cov khoom hauv kev ua lag luam."
Nrog rau kev loj hlob sai ntawm cov lag luam xws li kev tsim khoom siv siab thiab cov tsheb fais fab tshiab, qhov kev thov rau cov hlau sib xyaw ua ke zoo yuav txuas ntxiv mus ntxiv. ZZ Group tau hais tias nws yuav txuas ntxiv vam khom nws cov peev txheej muaj zog thiab cov peev xwm kev pabcuam los txhawb kev siv cov khoom siv hlau zoo hauv ntau qhov chaw lag luam.
