Qhov tsis xws thiab Countermeasures ntawm loj forgings: Uneven microstructure thiab cov khoom

Loj forgings, vim lawv qhov loj me, ntau cov txheej txheem, lub voj voog ntev, tsis sib xws hauv cov txheej txheem, thiab ntau yam tsis ruaj khov, feem ntau ua rau muaj qhov tsis sib xws hauv microstructure, yog li lawv tsis tuaj yeem xeem dhau cov khoom siv cuab yeej ntsuas, tshuaj xyuas metallographic thiab tsis- kev puas tsuaj nrhiav pom.

Vim muaj kev sib cais ntawm cov tshuaj muaj pes tsawg leeg, suav nrog tsub zuj zuj thiab ntau yam pore defects nyob rau hauv lub ingot;
Thaum cua sov, qhov kub hloov maj mam, qhov kev faib tawm tsis sib npaug, qhov kev ntxhov siab sab hauv yog loj, qhov tsis xws luag yog ntau;
Kub kub thiab lub sij hawm ntev forging, kev nyuaj siab hauv zos thiab lub zos deformation, yas ntws raws li txoj cai, degree ntawm compaction, deformation faib yog txawv heev;
Thaum lub sij hawm txias, cov txheej txheem diffusion yog qeeb, cov ntaub so ntswg transformation yog complex thiab cov kev ntxhov siab ntxiv yog loj.
Tag nrho cov saum toj no tej zaum yuav ua rau inhomogeneity loj ntawm cov ntaub so ntswg kev ua tau zoo thiab unqualified zoo.
Kev ntsuas los txhim kho qhov sib xws ntawmloj forgings:
1. Txais siv tshuab smelting siab heev los txhim kho qhov zoo ntawm cov hlau ingot;
2. Txais kev tswj forging, tswj cov tshuab cua txias, txhim kho cov txheej txheem thev naus laus zis, thiab txhim kho cov txheej txheem thiab kev lag luam ntawm loj forging ntau lawm.
