Daim ntawv thov ntawm cov menyuam tuag kos duab thev naus laus zis hauv kev tsim cov niobium zirconium alloy hlau

Roller die drawing technology yog ib qho kev txhim kho sai thiab ua tau zoo tshiab kos duab thev naus laus zis nyob rau hauv xyoo tas los no, uas muaj qhov tshwj xeeb zoo piv rau cov duab kos duab. Lub ntsiab lus ntawm cov menyuam tuag daim duab yog los hloov cov zawv zawg kev sib txhuam ntawm cov khoom thiab cov tuag L thaum lub sij hawm tsau tuag kos duab rau hauv cov dov kev sib txhuam ntawm lub zoo lubricated bearing, yog li ntawd zoo heev txo cov kev sib txhuam quab yuam. Tebchaws Asmeskas tau siv cov tshuab tuag rau kev tsim khoom hauv xyoo 1960, thiab tam sim no siv rau kev tsim cov tooj liab, txhuas thiab nws cov alloys, stainless hlau, thiab kub-kub alloys. Lub teb chaws Yelemees kuj tseem siv cov tshuab tuag rau kev kos cov txhuas, tooj liab, thiab nyuaj rau deform alloys. Cov qub Soviet Union tau txuas nrog qhov tseem ceeb rau cov menyuam tuag kev kos duab thev naus laus zis, tshwj tsis yog rau kev txhim kho kev hloov pauv tsis siv neeg tuag L nrog kev hloov kho tsis siv neeg. Ntxiv nrog rau cov khoom siv rau cov menyuam pwm rau qhov chaw, ib lub pwm rau cov menyuam nrog kev txhawb nqa rollers kuj tau tsim, Thaum ua kom lub zog ntawm cov ncej, nws kuj txhim kho qhov tseeb ntawm cov khoom. Tam sim no, muaj cov lus ceeb toom nyob rau hauv Suav teb tias yob tuag tshuab yog siv rau zus tau tej cov titanium thiab titanium alloy hlau. Lub koom haum Northwest Nonferrous Hlau Tshawb Fawb tau ua tiav cov khoom siv yob tuag kos duab los ntawm Russia mus rau kev tsim cov titanium thiab titanium alloy hlau. Txawm li cas los xij, tam sim no tsis muaj cov ntaub ntawv qhia txog daim ntawv thov ntawm yob tuag kos duab thev naus laus zis hauv kev tsim cov niobium zirconium alloy hlau Niobium zirconium alloy hlau yog tshwj xeeb tshaj yog tsim rau kev tsim khoom ntawm high-pressure sodium teeb vim nws kub tsis kam, corrosion kuj, thiab kev ua haujlwm txias ua haujlwm zoo, tshwj xeeb tshaj yog vim nws cov coefficient ntawm thermal expansion ntawm qhov kub thiab txias zoo ib yam li cov khoom siv ceramic. Niobium zirconium alloy muaj qis zog thiab zoo plasticity, thiab cov tsoos tsau tuag txias ua cov txheej txheem feem ntau yog siv. Niobium zirconium hlau yog kos siv qhov tuag tas, thiab qhov chaw ua ntej ntawm cov hlau yuav tsum tau ua ua ntej kos duab. Lub thiaj li hu ua pretreatment yog cov khoom tsim ntawm lub lubricating tiv thaiv zaj duab xis nyob rau saum npoo ntawm niobium zirconium alloy hlau los xyuas kom meej ib txwm kos duab ntawm cov hlau, uas yog cov txheej txheem tshuaj. Qhov no yog vim hais tias niobium zirconium alloy muaj qhov siab "Adhesion", yog tias tsis kho ua ntej, cov khoom siv lo lo ntxhuav yuav ua raws li qhov chaw sab hauv ntawm qhov chaw ruaj khov ntawm qhov ruaj khov tuag thaum lub sij hawm kos duab, qhov thiaj li hu ua "sticking pwm" yog tsim, thiab nyob rau hauv cov xwm txheej hnyav, cov hlau yuav tawg vim pwm scraping, ua rau nws tsis tuaj yeem ua cov duab kos. Yog li ntawd, tsis muaj qhov chaw ua ntej, qhov kev teeb tsa ruaj khov ntawm niobium zirconium hlau tsis tuaj yeem nqa tawm.
