Hauv kev lag luam xws li kev tsim cov khoom siv thiab kev ua hlau,pom hniav blanksyog cov khoom tseem ceeb uas txiav txim siab txiav efficiency thiab kev pab lub neej. Tuam Tshoj tus saw hniav dawb paug lag luam loj yuav tsum tshaj 9.3 billion yuan nyob rau hauv 2025, nrog rau kev thov rau siab -kawg cov khoom loj hlob los ntawm ntau tshaj 14% txhua xyoo. Lub sophistication ntawm cov txheej txheem ntau lawm ncaj qha dictates cov khoom sib tw. Niaj hnub no, peb yuav rhuav tshem tag nrho cov txheej txheem ntawm sawb blanks los ntawmsiab - zoo steel phajrausiab - cov khoom tiav tiav, nthuav qhia cov txuj ci paub- ua li cas tom qab lawv.
1. Kauj Ruam 1: Siab - Cov Hlau Hlau - Qhov "Code" ntawm qhov tsis zoo
Pom hniav dawb cov ntaub ntawv nyoos yog deb ntawm cov hlau zoo tib yam; lawv yogtshwj xeeb siab- cov cuab yeej carbon steel / siab- ceev steel(qee qhov siab- cov khoom siv kawg siv cov khoom siv hmoov metallurgy). High- zoo steel daim hlau yuav tsum tau raws li:
- Thickness kam rau ua Tsawg dua los yog sib npaug rau ± 0.02mm
- Tsis muaj oxide txheej lossis impurities ntawm qhov chaw
- Uniform internal qauv (kom tsis txhob deformation thaum lub sij hawm tom qab kev kho cua sov)
Kev lag luam Trend: Xyoo 2025, kev thov rau ultra-thickness sawb blanks (thickness Tsawg dua los yog sib npaug rau 1.2mm) yog loj hlob ntawm 21.4%, yuav tsum tau stricter phaj precision.
2. Laser Txiav: "Contour Sculptor" rau millimeter -Level Precision
Tsoos txiav yooj yim ua rau steel phaj thermal deformation, thaumlaser txiavNws yog ib qho tseem ceeb kom ua tiav high precision:
- Ua ntej txiav rau hauv daim phiaj ncig nrog qhov chaw nruab nrab (3 hli machining nyiaj tshwj tseg)
- Qhov thib ob txiav los ua cov hniav, suab -damping slots, thiab expansion grooves
- Ib txhij tshem tawm oxide nplai thiab burrs, tswj qhov roughness hauv qab Ra1.6
Qhov zoo: Piv rau hlau txiav, laser txiav yog 30% ntau npaum, nrog roundness yuam kev tsawg dua los yog sib npaug rau 0.05mm (ua tau raws li kev xav tau kev ua tiav).
3. Quenching + Tempering: "Core Magic" uas txiav txim siab hardness thiab toughness
Kev kho cua sov yog "tus ntsuj plig txheej txheem" ntawm kev pom cov hniav dawb paug, suav txog 70% ntawm cov nqi tsim khoom:
- Quenching: Tuav ntawm 820℃rau 20 feeb, ces quench nyob rau hauv 300℃molten ntsev rau 5 vib nas this kom ceev ceev hardness mus rau ntau tshaj 55HRC
- Siab Leveling: Nias nrog daim hlau ntawm chav tsev kub rau 150 vib nas this, tswj flatness Tsawg dua los yog sib npaug rau 0.03mm
- Secondary TemperingTuav ntawm 480℃rau 30 feeb kom tso tawm qhov kev ntxhov siab, nrog qhov kawg hardness ruaj khov ntawm 48 ± 1HRC
Kev Txhim Kho Kev Txhim Kho: Cov txheej txheem "ob npaug- dawb paug stacking ib lub cub tawg" ua kom cov cua sov zoo sib xws, ua kom muaj kev ntxhov siab ntau ntxiv los ntawm 40%.
4. Precision Sib Tsoo + Kev Tshuaj Xyuas: Kev ruaj ntseg "Qhov Kawg Precision Checkpoint"
- Inner Hole Precision Sib Tsoo: Cov txheej txheem mounting qhov nrog sab hauv cylindrical grinders, ua tiav IT6-theem aperture precision kom tsis txhob teeb tsa eccentricity
- Dynamic Balance Testing: Eccentricity yuav tsum
- Kev soj ntsuam Flatness: Roj zaj duab xis optometry xyuas kom tag nrho nto 贴合, nrog yuam kev <0.03mm
Kev hloov pauv ntse: Hauv xyoo 2025, ntau dua 45% ntawm cov lag luam siv cov kev tshuaj ntsuam xyuas ntse, txhawb cov txiaj ntsig ntau dua 96%.
5. 2025 Siab-High Trends rau Saw Blade Blanks
Kev lag luam tam sim no hloov kho mus rausiab- cov ntaub ntawv kawg, kev tsim khoom ntse, thiab cov xwm txheej tshwj xeeb:
Cov ntaub ntawv: Nanocrystalline reinforced steel thiab carbon fiber composite blanks tau dhau los ua ntau dua
Cov txheej txheem: AI- kho kom zoo thaum tshav kub kub nkhaus txo kev siv zog los ntawm 19.4%
Daim ntaub ntawv: Cua fais fab/photovoltaic sectors pom surged thov rau loj - txoj kab uas hla (Ntau tshaj los yog sib npaug rau 1000mm), siab -rigidity blanks
