Feem ntau faults thiab tiv thaiv txoj kev ntawm lub pob tw vuam tshuab

Lub taub qab vuam tshuab hauv pob tw vuam, vim tias qhov kawg hlau raug hlawv thaum cua sov, yog li qhov kawg tu yuav tsum tsis siab, tab sis kev tu cov khoom siv thiab vuam kev sib cuag saum npoo thiab cov pob tw vuam yog tib yam, yog li cov khoom siv yuav muaj. qee qhov kev ua tsis tiav me me vim yog lwm yam.
Feem ntau faults thiab tiv thaiv txoj kev:
1. Dislocation: Qhov laj thawj tuaj yeem yog qhov vuam tsis sib haum lossis qaij thaum lub sijhawm sib dhos, qhov vuam vuam yog overheating, thiab qhov ntev txuas ntxiv yog qhov loj heev. Lub rigidity ntawm lub vuam tshuab tsis loj txaus, thiab lwm yam, lub ntsiab tiv thaiv kev ntsuas yog los txhim kho lub rigidity ntawm cov cuab yeej, txo qhov ncua ntev thiab tsim nyog txwv lub Upper forging nyiaj, thiab qhov tso cai yuam kev ntawm dislocation yog feem ntau tsawg dua. 0.1mm lossis 0.5mm thickness.
2, tawg: qhov ua rau tej zaum yuav nyob rau hauv lub vuam ntawm high carbon steel thiab tsawg carbon steel quenching nyiam, yuav siv tau rau preheat, tom qab tshav kub thiab raws sij hawm annealing ntsuas los tiv thaiv.
3, tsis ua hauj lwm los ntawm vuam: qhov ua rau tej zaum yuav yog hais tias qhov kub ntawm lub interface ua ntej lub forging sab saum toj yog tsawg heev, lub sab saum toj forging nyiaj pub tsawg heev, lub sab saum toj forging siab thiab sab saum toj forging ceev yog tsawg, thiab tsis ua hauj lwm rau welding. los ntawm yog tshwm sim los ntawm cov hlau ntau dhau lawm, kev tiv thaiv kev ntsuas yog siv cov txheej txheem kev sib tsoo pob tw uas tsim nyog.
4, qhov chaw dawb: qhov tsis xws luag ntawm vuam ntawm qhov tawg ntawm cov radial grey dawb uas twb muaj lawm, qhov kev tsis zoo no yog qhov nyias nyias, tsis yooj yim pom nyob rau hauv metallographic sib tsoo zaj duab xis, hauv electron microscope tsom pom, qhov chaw dawb yog ntau rhiab heev rau txias dabtsi yog khoov, tab sis qhov cuam tshuam ntawm tensile lub zog me me, tuaj yeem raug tshem tawm los ntawm kev ntsuas nrawm thiab txaus forging.
Butt welding tshuab kuj tuaj yeem ua ke nrog lwm cov khoom siv automation kom ua tiav tag nrho automation ntawm taub qab vuam tshuab.
