"Hand-shredded steel" tau qhia ob peb zaug, yog li txhua tus yuav tsum paub txog nws. Niaj hnub no cia peb saib cov tswv cuab tshiab ntawm tsev neeg hlau - "Cicada Wing Steel" (tseem hu ua "5G Steel"), uas yog nyias li cicada tis thiab lub teeb zoo li daim iav!
Tsis ntev los no, qhov kev hloov kho tshiab cuv npe nkag ntawm University of Science thiab Technology Beijing tau nthuav tawm: siv hlau ua ntawv! Lub cev tseem ceeb ntawm daim ntawv ceeb toom nkag yog ua los ntawm "Cicada's Wing Steel" uas yog nyias li cicada lub tis, lub teeb zoo li daim iav, tawv li hlau, thiab hloov tau zoo li ntoo thuv.

Lub thickness ntawm "Cicada Wing Steel" tuaj yeem ua nyias li 0.07mm. Nws yog tsuas yog siv rau 5G hauv paus chaw nres tsheb teeb liab receivers, teeb liab kis tau tus mob lim, integrated circuit boards, thiab lwm yam., kuj hu ua 5G steel.
Qhov tseeb, qhov no tsis yog nws thawj qhov tsos. Thaum lub caij 2022 Beijing Winter Olympics, "Cicada Wing Steel" tau hloov pauv mus rau lub caij ntuj no Olympic ntawv tshaj tawm. 15 cov duab ua kis las thiab 15 lub cim kev ua kis las ntawm Beijing Lub caij ntuj no Olympic mascot Bing Dundun tau nthuav tawm nyob rau hauv qhov nyuaj-tempered "cicada tis steel", sau cov "Song of Ice and Fire".

"Cicada Wing Steel" cov khoom yog nrov heev nyob rau hauv cov kab lis kev cai thiab muaj tswv yim teb. Thaum Lub Kaum Hli 16, 2022, Tuam Tshoj Post tau tshaj tawm lub teb chaws version ntawm "Cicada Wing Steel" xa ntawv rau "Twentieth National Congress of the Communist Party of China". Daim ntawv tshaj tawm yog ua los ntawm cov khoom siv high-tech "Cicada's Wing Steel" uas tsim los ntawm Shougang Jingtang Company. Lub Great Phab Ntsa ntawm qhov chaw tshaj tawm ntawm "Cicada's Wing Steel" daim ntawv tshaj tawm tau txais kev siv tshuab hollowing. Lub Great Wall lub pob tshab steel thev naus laus zis tau sib xyaw ua ke nrog daim duab, qhia txog "Great Wall of Steel".

"Cicada Wing Steel" belongs rau cov hlau rau 5G khoom tsim los ntawm Shougang Jingtang Company. Lub thickness ntau yog 0.07 ~ 0.15mm, uas tsuas yog sib npaug rau txoj kab uas hla ntawm cov plaub hau. Nws yog ib qho tseem ceeb heev rau steel purity, mechanical zog, thickness raug, phaj puab thiab nto. Cov kev cai zoo yog nruj heev. "Thin" thiab "glossy" yog cov yam ntxwv ntawm cov khoom no, thiab lawv kuj yog cov teeb meem hauv kev tsim khoom. Nrog ntau tshaj 300 cov txheej txheem me me thiab ntau txhiab lub ntsiab lus tswj tau zoo, Jingtang Company tau ua tiav cov teeb meem zoo tshaj plaws nrog nws cov peev txheej tsim muaj zog thiab kev tswj hwm qib. Muaj ntau lub fwj thiab lub cev tsis muaj zog xws li kev tswj xyuas kev ua haujlwm siab ntawm cov khoom me me hauv cov lus qhia nyias, kev kub ceev thiab ruaj khov strip threading thiab flatness tswj tshuab ntawm ultra-thin acid nruam dov nrog sib txawv thickness, thiab theem nrab txias dov tshuab ntawm ultra-nyias specifications nrog ib tug loj nam piv.

"Nws yog qhov nyuaj heev los txo qhov tuab ntawm txawm tias {{0}}.01 hli thiab yuav tsum muaj kev sib koom tes ntawm txhua qhov chaw tsim khoom." Mo Zhiying, tus kws tshaj lij ntawm Shougang Metal Materials, muaj kev nkag siab tob txog qhov no. Nyob rau hauv cov txheej txheem steelmaking, cov pa roj carbon thiab oxygen cov ntsiab lus ntawm tag nrho cov rauv ntawm Shougang Jingtang Steelmaking Converter (ib qho tseem ceeb qhia rau kev ntsuas qhov huv si ntawm molten steel) tau mus txog lub thoob ntiaj teb ua theem, thiab nws tau xub tsim cov slabs dawb huv nrog ib tug tuab ntawm 230. mm thiab dav ntawm 1 meter. Nyob rau hauv cov txheej txheem kub dov thiab txias dov, lub slab maj mam ua thinner thaum muaj ntau yam dov thiab annealing txheej txheem. Thaum Lub Ob Hlis 2022, lub thickness ntawm Shougang's "Cicada Wing Steel" tau ua tiav txo qis mus rau qhov tshwj xeeb ultra-nyias ntawm 0.07 hli, kos ib theem tshiab ntawm Shougang Jingtang cov khoom tsim khoom siab kawg.
