Stainless hlau (cov neeg nyiam tsuas yog "stainless hlau") yog tshwj xeeb cov hlau-carbon hlau, uas yog qhov nrov tshaj plaws ntawm txhua hom hlau. Qhov zoo ntawm stainless hlau - zoo tiv thaiv corrosion, nto smoothness, tu cev, lub zog, manufacturability. Tab sis nws tshwm sim hais tias hom hlau tsis ua tiav, thiab nws yuav tsim nyog los txuas nws.
Nws yog qhov tsim nyog
Qee qhov kev tsim nyog rau kev ua haujlwm nrog vuam tshuab kom tus txheej txheem no ua tau sai sai, muaj txiaj ntsig thiab tsis muaj kev phom sij rau ib tus neeg
Cov Lus Qhia
Kauj ruam 1
Ua noj stainless hlau siv tus ntsia hlau thiab ncaj, tab sis tsis yog ib qho yooj yim, tab sis qhov txuas ntxaws nrog txhawm chim. Cov kev ib txwm yuav tsis ua haujlwm kiag li, vim nrog nws cov txheej txheem yuav mus nyuaj thiab tig mus ua kev tsim txom tsis tu ncua, yog li yuav tsum tseg koj cov leeg thiab coj qhov koj xav tau. Tsis tas li, rau vuam tsis xeb hlau, koj yuav xav tau cov xaim hluav taws xob tshwj xeeb, zoo dua yog qhov zoo, tsis li ntawd tag nrho cov txheej txheem yuav puas. Nws tseem tuaj yeem yog cov electrodes dub, tab sis qhov no, teeb meem nrog tus nqaws tuaj yeem tshwm sim. Zoo dua los ua noj khov hlau nrog argon. Yog tias koj tsis muaj cov cuab yeej siv rau qhov kev xaiv no, tom qab ntawd mus rau kauj ruam 2.
Kauj ruam 2
Weld nyob rau hauv lub xeev preheated ntawm qhov kub ntawm txog 2000 degrees, ua tib zoo xyuas kom paub tseeb tias cov cua kub ntawm cov hlau tsis xeb thaum vuam yog tsawg heev. Yog tias peb sib piv, tom qab ntawd qhov txiaj ntsig tau ntxiv yog tau nrog hluav taws xob arc dua nrog roj vuam. Tom qab ua haujlwm tiav, tso cov cua kub txuas rau 7200-7800 degrees thiab tom qab ntawd txias kom sai. Yog tias koj tsis muaj cov cuab yeej siv rau qhov kev xaiv no, tom qab ntawd mus rau kauj ruam 3.
Kauj ruam 3
Ua noj stainless hlau ntawm kev kub ceev thiab ceev ceev heev, uas feem ntau tuaj yeem ua tiav los ntawm txias lossis tooj liab thiab weld cov ntaub qhwv. Yav dhau los, cov khoom yuav tsum raug "tawv tawv" 1050-1150 degrees, ua raws li kev txias sai. Yog tias koj tsis muaj cov cuab yeej siv rau qhov kev xaiv no, ces mus rau qib 4.
Kauj ruam 4
Preheat stainless hlau rau 2500-3500 degrees ua ntej vuam. Qhov no yuav zam qhov pom ntawm tawg thiab tawg ntawm welded pob qij txha. Siv cov austenitic steel ua cov ntawv electrodes, uas ua rau cov ntawv xa tawm nruj. Qhov tseem ceeb tshaj plaws yog ua txhua yam kom zoo, ntsuas thiab ntsuas, thiab tom qab ntawd qhov tshwm sim ntawm qhov tsis raug thiab qhov ua tsis tiav thaum vuam yuav tsawg heev.
