Lub luag haujlwm tseem ceeb ntawm alumina hmoov hauv cov ntaub ntawv refractory

Cov neeg uas tau ua hauj lwm hauv refractory Rhiav paub hais tias qhov kev lag luam no yog ntau picky txog cov ntaub ntawv tshaj li alchemy rauv ntawm Taishang Laojun - qhov kub thiab txias yuav tsum muaj peev xwm tiv taus lub roasting ntawm 2000 ℃, thiab cov kua qaub thiab alkali corrosion yuav tsum muaj peev xwm tiv taus kev cai raus dej ntawm aqua regia. Yog tias koj xav hais tias cov khoom twg tuaj yeem ruaj khov zoo li tus dev qub hauv qhov kev xeem "ntev ntuj raug txim" no,alumina hmoovyog qhov kev xaiv zoo tshaj plaws. Cov hmoov dawb no zoo li qub, tab sis nws yog "hexagonal warrior" hauv kev lag luam refractory. Niaj hnub no, cia peb saib yog vim li cas nws thiaj tuaj yeem muab tso rau hauv qhov cub ua haujlwm.

Ⅰ. "Hardcore cwj pwm" nrog tag nrho cov txuj ci ntsiab lus 139

Lub peev xwm ntawmalumina hmoovpib nrog nws "peb axes". Ua ntej ntawm tag nrho cov, lub melting point ntawm cov khoom no yog siab li 2050 ℃, uas yog ntau resistant rau hlawv tshaj Sun Wukong lub golden hoop. Zhang, tus tswv ntawm lub cub tawg tawg ntawm cov nroj tsuag hlau hauv Shandong, ib zaug hais tias: "Qhov kub hauv peb lub cub tawg tau nce mus txog 1800 ℃, tab sis cov alumina cib tseem tsis hloov pauv. Lawv muaj zog dua qhov cub hluav taws xob hluav taws xob ntawm Chav Ua Noj Vajtswv!"

Kev ruaj ntseg tshuaj yog qhov tshwj xeeb dua. Cov sulfuric acid cia tso tsheb hlau luam ntawm Ningbo Chemical Plant yog coated nrog alumina txheej, thiab txawm tias ib tug ripple tsis tshwm sim tom qab soaked nyob rau hauv concentrated acid nrog ib tug pH nqi ntawm 1 rau ib nrab xyoo. Tus kws tshuaj ntsuam xyuas Wang tau khav theeb nrog tus qauv: "Nrog rau qhov kev tiv thaiv corrosion no, txawm tias Taishang Laojun yuav tau muab ib lub npib Suav!

Lub slag yaig tsis kam yog qhov txaus ntshai tshaj. Tom qab cov hlwb electrolytic ntawm ib pawg kev lag luam txhuas hauv Henan tau hloov nrog alumina-raws li cov ntaub ntawv refractory, lawv lub neej kev pabcuam tau nce ncaj qha los ntawm 3 lub hlis mus rau 2 xyoos. Tus thawj coj ntawm lub rooj cob qhia Li suav nrog luam yeeb hauv nws lub qhov ncauj: "Cov nqi kho mob tau txais txiaj ntsig txaus los hloov cov tshuab cua txias hauv nruab nrab rau tag nrho lub Hoobkas!"

II. "Master of Form" nrog 72 kev hloov pauv 267

Thaum alumina hmoov ua si "Metamorphosis", txawm Monkey King yuav tsum hu nws Master. Nano-alumina hmoov, lub tshuab dub, tuaj yeem ua rau lub zog ntawm cov ntaub ntawv refractory nyuaj dua li cov pob zeb uas muaj zog. Cov ntaub ntawv los ntawm lub chaw soj nstuam hauv Shenzhen qhia tias ntxiv 5% nano-alumina tuaj yeem ua ob npaug ntawm cov khoom siv thiab txo qhov kub ntawm sintering los ntawm 200 ℃. Tus kws tshawb fawb Xiao Liu thawb nws lub tsom iav thiab hais tias: "Nws zoo li kev txhaj tshuaj super serum rau hauv cov khoom siv!"

Active aluminayog siv ntau dua. Lub Hoobkas refractory nyob rau hauv Jiangsu siv nws los sib tov castables, thiab cov fluidity yog zoo li mis nyuj tshuaj yej. Tsis txhob hais txog cov dej yog txiav los ntawm 30%, qhov ntom ntawm cov khoom tiav yog ze rau lub qhov dub. Tus Xib Hwb Lao Zhao tau khav theeb nrog lub tshuab ntsuas hluav taws xob: "Cov qauv no yog tuab heev uas txawm tias ntsaum yuav poob yog tias lawv nkag mus!"

Kev sib xyaw ua ke ntawm micro-hmoov ntawm qhov sib txawv particle qhov ntau thiab tsawg yog qhov tsis meej. Ib lub koom haum tshawb fawb hauv Changchun pom tias cov thermal shock tsis kam ncaj qha los ntawm kev sib xyaw 1μm thiab 5μm alumina hmoov hauv qhov piv "3: 7". Cov khoom loj tuaj yeem tiv taus kev puas tsuaj, cov khoom me me tuaj yeem ua rau qhov khoob, thiab kev sib xyaw ua ke yog invulnerable! "

Ⅲ. "Highlight moments" ntawm qhov chaw sib ntaus sib tua 4910

Hauv cov hlau thiab hlau metallurgical lub voj voog, alumina hmoov yog "cov khoom siv hluav taws xob tiv thaiv hluav taws xob". Tom qab lub qhov hluav taws xob tawg qhov hluav taws xob ditch ntawm cov nroj tsuag steel hauv Hebei Xeev tau tso siab rau cov alumina-based castables, nws lub neej kev pabcuam tau nce los ntawm 200 rau 800 rauv. Lao Zhou, ib tug neeg ua hauj lwm rau lub cub tawg, patted lub cub tawg thiab luag: "Tam sim no lub cub tawg yog ruaj dua kuv lub siab cooker!"

Kev lag luam petrochemical tau mus txog qhov siab tshiab. Tom qab lub catalytic cracking unit ntawm lub refinery nyob rau hauv Qingdao tau hloov nrog alumina hnav-resistant hauv ob sab phlu, lub sij hawm txij nkawm tau ncua ntawm 3 lub hlis mus rau 1 xyoo. Tus thawj tswj khoom siv Lao Ma yws nrog rab phom vuam: "Tam sim no kuv tsis ua haujlwm dhau los ntxuav cov cuab yeej txhua hnub, thiab kuv cov nyiaj tau los yuav luag tag!"

Ⅳ. "Arms haiv neeg" ntawm thev naus laus zis hloov kho 2610

Tam sim no ua si nrog alumina hmoov, qhov tseem ceeb ntawm "nano-theem tswj". Ib lub chaw kuaj mob hauv Beijing tau tsim "atomic dispersion" thev naus laus zis, uas ua rau kev ua haujlwm ntawm alumina hmoov ntau dua li cov tub ntxhais hluas. Lub sintering kub yog txo mus rau 300 ℃, thiab lub zog noj yog ncaj qha txiav nyob rau hauv ib nrab. Tus kws tshawb fawb Lao Wang tau khav tias: "Tam sim no kev tua lub cub zoo li ci ci, thiab kev tswj qhov kub thiab txias yog qhov tseeb dua li kuv qhov cub!"

Txoj kev ua si nrog cov ntaub ntawv sib xyaw yog qhov zoo siab dua. Ib lub tuam txhab hauv Xi'an muab cov hmoov alumina nrog silicon carbide los tsim cov cib refractory uas yog ob qho tib si tiv taus thermal shock thiab yaig. Tus Xib Hwb Lao Zhou tau tuav nws lub taub hau thaum kov lub workpiece tshiab: "Lub tshuab tam sim no tau tshem tag nrho cov hauj lwm ntawm Lu Ban!"

Los ntawm alchemy rauv ntawm Taishang Laojun mus rau lub melting rauv ntawm niaj hnub kev lag luam, alumina hmoov tau ua pov thawj nrog lub zog: koj txiv ntxawm yog koj txiv ntxawm! Cov pawg ntawm cov hmoov dawb no tau poked lub qhov nyob rau hauv kev ua tau zoo qab nthab ntawm cov ntaub ntawv refractory. Cov tswv hauv kev lag luam txhua tus hais tias tsis muaj alumina hmoov, cov ntaub ntawv refractory yuav tsum tau rov qab 30 xyoo. Yog tias qhov kev hloov no txuas ntxiv mus, txawm tias qhov cub barbecue yuav tsum tau siv aerospace-qib refractory coatings ib hnub - tom qab tag nrho, leej twg tsis xav kom lawv lub qhov cub barbecue nyob rau tib theem li cov nroj tsuag steel.tawg rauv?
