Khoom Description
Alloy cored hlau yog ib hom vuam consumable uas tau siv dav hauv kev lag luam vuam. Nws yog steel hlau coated nrog alloying ntsiab uas ntxiv rau lub pas dej ua ke thaum vuam. Lub alloy cored hlau cov ntsiab lus tuaj yeem ua raws li cov kev xav tau tshwj xeeb ntawm kev siv vuam sib txawv. Hauv tsab xov xwm no, peb yuav tham txog cov txiaj ntsig ntawm customizing alloy cored hlau cov ntsiab lus thiab cov yam uas yuav tsum tau xav txog thaum ua li ntawd.
Customizing alloy cored hlau cov ntsiab lus muaj ntau yam zoo. Ua ntej, nws tso cai rau cov welders kom ua tiav cov khoom xav tau ntawm cov khoom sib txuas. Cov ntsiab lus alloying hauv cored hlau tuaj yeem txhim kho lub zog, ductility, thiab toughness ntawm cov hlau vuam. Piv txwv li, ntxiv manganese rau cov hlau cored tuaj yeem ua rau lub zog thiab hardness ntawm vuam, thaum ntxiv npib tsib xee tuaj yeem txhim kho nws qhov tawv thiab corrosion kuj.
Thib ob, customizing cov alloy cored hlau cov ntsiab lus tuaj yeem txhim kho qhov weldability ntawm lub hauv paus hlau. Lub hauv paus hlau yuav muaj qee qhov kev txwv ntawm cov khoom siv hlau uas tuaj yeem siv tau vim nws cov tshuaj muaj pes tsawg leeg. Piv txwv li, cov hlau tsis tshua muaj carbon steel hlau yuav xav tau cov hlau cored nrog cov ntsiab lus carbon tsawg kom tsis txhob muaj teeb meem xws li porosity lossis tawg.
Thib peb, customized alloy cored hlau cov ntsiab lus tuaj yeem txo qhov kev xav tau ntawm kev kho cua sov tom qab vuam. Qee cov ntsiab lus alloying, xws li molybdenum, tuaj yeem txhim kho qhov kub ntawm lub zog ntawm cov hlau vuam, txo qhov kev pheej hmoo ntawm distortion los yog tawg thaum lub caij txias. Qhov no tuaj yeem tshem tawm qhov xav tau ntawm kev siv nyiaj kim thiab siv sijhawm ntev tom qab kev kho cua sov, uas tuaj yeem txuag sijhawm thiab nyiaj txiag.
Thaum customizing alloy cored hlau cov ntsiab lus, ntau yam yuav tsum tau muab coj los xav. Ua ntej, cov tshuaj muaj pes tsawg leeg ntawm lub hauv paus hlau yuav tsum tau soj ntsuam los txiav txim siab cov ntsiab lus alloying tau sib xws nrog nws. Cov tshuaj ntsuam xyuas ntawm lub hauv paus hlau kuj tuaj yeem pab xaiv qhov tsim nyog cored hlau txoj kab uas hla thiab muaj pes tsawg leeg.
Qhov thib ob, cov txheej txheem vuam tsis zoo, xws li vuam tam sim no, qhov hluav taws xob, thiab kev mus los ceev, yuav tsum tau txiav txim siab thaum xaiv cov hlau cored. Lub cored hlau yuav tsum muaj peev xwm muab qhov ruaj khov arc thiab zoo weld nkag mus rau hauv cov txheej txheem muab.
Thib peb, yuav tsum tau txiav txim siab cov khoom siv kho tshuab ntawm cov vuam sib txuas. Cov ntsiab lus ntawm cov hlau cored hlau yuav tsum raug xaiv los muab cov khoom xav tau xws li lub zog tensile, hardness, toughness, los yog qaug zog.
Plaub, hom kev thov vuam yuav tsum raug txiav txim siab. Kev siv vuam sib txawv muaj cov kev xav tau sib txawv rau kev sib koom ua ke, xws li hom kev thauj khoom, kev ua haujlwm kub, lossis ib puag ncig. Lub cored hlau yuav tsum raug xaiv los muab kev ua tau zoo tshaj plaws hauv daim ntawv thov.
Hauv kev xaus, customizing alloy cored hlau cov ntsiab lus yog cov txheej txheem tseem ceeb rau kev txhim kho qhov zoo thiab kev ua tau zoo ntawm cov pob qij txha welded. Nws tso cai rau welders los txiav cov alloying ntsiab nyob rau hauv lub cored hlau kom tau raws li cov kev xav tau tshwj xeeb ntawm kev siv vuam sib txawv. Txawm li cas los xij, ntau yam yuav tsum tau xav txog thaum ua li ntawd, xws li tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau hauv paus, cov txheej txheem vuam, cov cuab yeej siv tau zoo, thiab hom kev thov vuam. Los ntawm kev noj cov khoom no rau hauv kev xav, cov welders tuaj yeem xyuas kom lawv xaiv qhov zoo tshaj plaws alloy cored hlau rau lawv cov kev xav tau vuam.
