Rollers raug khoov, sib txhuam, kev cuam tshuam, thiab lwm yam teebmeem thaum lub sij hawm dov, uas feem ntau ua rau tev thiab hnav ntawm cov yob nto. Yog li ntawd, qhov yob nto feem ntau yuav tsum muaj lub zog siab, hardness, hnav tsis kam, thiab qaug zog txwv. Cov khoom saum npoo no tsis yog tsuas yog cuam tshuam nrog cov khoom ntawm cov yob tab sis kuj rau cov txheej txheem kho saum npoo ntawm yob. Cov txheej txheem kho saum npoo ntawm cov yob feem ntau suav nrog tag nrho cov txheej txheem quenching ntawm yob, induction cua sov quenching txheej txheem, txheej txheem surfacing, thermal spraying txheej txheem, thermal spraying txheej txheem, thiab laser deg kev hloov kho txheej txheem. Peb lub tuam txhab tuaj yeem muab tungsten rollers ntawm ntau yam duab thiab ntau thiab tsawg. Yog tias koj xav tau xaj, koj tuaj yeem tiv tauj peb ntawm email.
1. Tag nrho cov txheej txheem quenching
Integral quenching yog kom sov tag nrho cov yob mus rau austenitizing kub rau quenching, thiab nyob rau tib lub sij hawm, lub caj dab yob yog tiv thaiv los ntawm rwb thaiv tsev cov ntaub ntawv los xyuas kom meej tias nws tuav zoo toughness. Tag nrho cov txheej txheem quenching yuav ua rau muaj kev ntxhov siab nyob rau hauv cov yob nto, ua rau cov yob muaj qhov tsis zoo ntawm cov txheej txheem ntiav ntiav, cov matrix tsis muaj zog, thiab kev sib tsoo tsis zoo.
2. Induction cua sov quenching txheej txheem
Cov txheej txheem cua sov induction quenching siv lub high-frequency AC magnetic teb kom sov lub yob ob zaug nyob rau hauv succession kom lub yob nto yog sai rhuab mus rau saum toj no qhov tseem ceeb kub, thiab ces txias sai sai kom tau martensite.
3. Overlay vuam txheej txheem
Tom qab lub yob puas lawm, nws nto yuav tsum tau kho. Overlay welding yog ib txoj kev kho uas feem ntau siv, uas yog yaj cov hlau los ntawm hluav taws xob vuam los yog roj vuam thiab muab tso rau ntawm qhov chaw yob. Txawm hais tias cov txheej txheem vuam txheej txheem tuaj yeem ua kom ntseeg tau qhov hnav tsis kam ntawm cov yob, tag nrho cov txheej txheem nyuaj heev, cov khoom tsim tau qis, thiab cov kev cai rau cov neeg ua haujlwm siab. Nyob rau tib lub sijhawm, cov yob yuav tsim cov pores, tawg, slag inclusions, thiab lwm yam teeb meem thaum lub sij hawm overlay vuam.
4. Thermal txau txheej txheem
Cov txheej txheem thermal txau yog txau cov molten lossis semi-molten txau cov khoom siv rau ntawm cov menyuam yaus ntawm kev kub ceev los tsim cov micro-metallurgical bonding lossis mechanical bonding txheej. Vim tias qhov sib txuas tsis tshua muaj zog ntawm cov txheej thiab cov substrate, feem ntau yog kev sib txuas ntawm cov khoom siv sib txuas, cov txheej txheem muaj qhov khoob thiab qhov seem seem, uas ua rau lub zog thiab kev ua haujlwm ntawm cov menyuam tsis zoo.
5. Thermal txau txheej txheem
Thermal spraying txheej txheem yog raws li cov txheej txheem thermal spraying. Cov tshuaj tsuag txheej yog remelted dua los ua kom cov tshuaj tsuag txheej thiab cov khoom siv substrate nto mus txog lub xeev molten, thiab tom qab ntawd cov txheej txheem sib khi ua kom nruj dua metallurgical txuas ntxiv. Thermal spraying tuaj yeem suav tau tias yog kev sib xyaw ua ke ntawm cov hlau txau thiab hlau ntog. Nws overcomes lub shortcomings ntawm tsawg bonding zog thiab tsawg hardness ntawm thermal spraying txheej. Nyob rau tib lub sijhawm, vim yog siv cov hmoov hlau alloy, cov txheej txheej txau muaj cov khoom tshwj xeeb, uas tsis muaj nyob rau hauv dav dav.
6. Laser nto kev hloov kho txheej txheem
Laser reinforcing yog irradiate cov menyuam nrog ib tug high-density, high-power laser beam kom lub nto kub ntawm cov menyuam instantly, yog li ua rau lub nto lub koom haum ntawm cov menyuam yuav tsum tau hloov. Yog li ntawd, nws muaj cov txiaj ntsig zoo xws li kev tswj tsis siv neeg siab qhov tseeb ntawm thaj chaw kho cua sov, cov qauv ua kom zoo heev ntawm thaj chaw ntxiv dag zog, me me thermal deformation ntawm lub workpiece, thiab siv cov taw tes ua lossis kab scanning ua kom tau txais kev txiav txim siab. ntxiv dag zog rau saum npoo nrog tib softness thiab hardness, lub zog thiab toughness.
