Daim ntawv coils - nplooj ntawv, strips, ntawv xov hlau - profiles, puag ncig, tiaj tus, square
Kev ua haujlwm thiab kev kho cua sov: Nws yog ib qho nyuaj-rau-cov khoom siv hauv kev ua haujlwm ntawm cov tshuab ua haujlwm.
Preheating: Qhov saum npoo ntawm lub workpiece yuav tsum tau ntxuav ua ntej cua sov thiab thaum lub sij hawm cua sov txheej txheem kom huv si nto. Yog tias qhov cua sov ib puag ncig muaj leej faj, phosphorus, txhuas, lossis lwm yam hlau uas tsis tshua muaj melting point, cov hlau yuav nkig. Cov impurities tuaj ntawm cov xim pleev xim, chalk, lubricants, dej, roj, thiab lwm yam. Cov ntsiab lus ntawm cov roj sulfur yuav tsum tsawg. Piv txwv li, cov ntsiab lus impurity ntawm cov roj av liquefied roj av thiab cov nkev ntuj yuav tsum tsawg tshaj li {{0}}.1%, cov ntsiab lus sulfur ntawm lub nroog roj yuav tsum tsawg dua 0.25g/m3, thiab sulfur cov ntsiab lus ntawm liquefied roj av yuav tsum tsawg tshaj li 0.5%.
Lub tshuab hluav taws xob cua sov yuav tsum muaj lub peev xwm tswj tau qhov kub thiab txias, cov roj cua hauv lub tshuab hluav taws xob yuav tsum yog nruab nrab lossis tsis muaj zog alkaline, thiab kev hloov pauv hauv cationic chemistry thiab txo cov khoom ntawm cov khoom siv hluav taws xob yuav tsum zam.
Kev ua haujlwm kub: Qhov tsim nyog kub ua haujlwm kub ntawm cov hlau yog 1120-900 degree, thiab txoj kev ua kom txias tuaj yeem yog dej quenching lossis lwm txoj kev ua kom txias sai. Annealing yuav tsum tau nqa tawm nyob rau hauv lub sij hawm tom qab thermal ua kom pom kev ua tau zoo. Thaum lub sij hawm thermal ua, cov khoom yuav tsum tau rhuab mus rau lub sab sauv txwv ntawm ua kub. Txhawm rau kom ua tiav plasticity thaum ua tiav, qhov kawg ua haujlwm kub thaum lub deformation mus txog 20% yuav tsum tsis txhob qis dua 960 degree.
Kev Ua Haujlwm Txias: Kev ua haujlwm txias yuav tsum tau ua tom qab kev kho kom zoo. Kev ua haujlwm hardening yog siab dua li ntawm austenitic stainless hlau, yog li cov cuab yeej ua haujlwm yuav tsum tau hloov kho raws li, thiab yuav tsum muaj cov txheej txheem annealing nruab nrab thaum ua haujlwm txias.
Nickel270 yog cov khoom tseem ceeb heev. Txawm hais tias tus nqi kuj yog siab heev, nws cov kev ua tau zoo thiab kev siv ntau yam ua rau nws ua tus thawj coj hauv kev lag luam high-end alloy khoom. Vim nws purity thiab zoo, Nickel 270 yog siv nyob rau hauv kev kho mob, khoom noj khoom haus thiab kev siv roj av. Hauv cov khoom siv kho mob, nws yog siv los tsim cov khoom zoo xws li cov pob qij txha, kev kho hniav thiab cov cuab yeej phais. Hauv kev ua zaub mov, npib tsib xee 270 yog siv los ua cov cuab yeej ua haujlwm kub kub thiab kub-kub ci racks. Hauv kev lag luam roj av, Nickel 270 yog siv los tsim cov khoom siv tiv thaiv nyob rau hauv qhov chaw corrosive thiab kub kub.
Nyob rau hauv luv luv, nrog rau txoj kev loj hlob ntawm science thiab technology thiab kev loj hlob ntawm kev lag luam, high-temperature alloys kuj tseem niaj hnub tsim thiab upgraded. Tam sim no, cov kws tshawb fawb tab tom tsim cov txheej txheem kub kub tshiab los txhim kho lawv cov khoom siv kho tshuab thiab cov khoom ua haujlwm, thiab tshawb nrhiav lawv cov ntawv thov hauv ntau thaj chaw. Nyob rau hauv lub neej yav tom ntej, high-temperature alloys yuav txuas ntxiv siv lawv cov cim zoo thiab dhau los ua ib qho ntawm cov neeg sawv cev tseem ceeb hauv kev ua haujlwm siab.
