Cov khoom siv rau cov pob tawb kho cua sov tuaj yeem sib txawv, nyob ntawm cov ntawv thov tshwj xeeb thiab cov kev xav tau. Cov khoom siv hluav taws xob zoo tshaj plaws feem ntau siv rau cov pob tawb kho cua sov xws li Inconel, Incoloy, Hastelloy, Nichrome, thiab Tungsten. Cov ntaub ntawv no raug xaiv rau lawv lub peev xwm los tiv taus qhov kub thiab txias (900 ~ 1200 degree) yam tsis muaj deformation thiab tuav ruaj khov muaj peev xwm.
Ntxiv nrog rau cov khoom siv hlau, graphite kuj tseem siv los ua cov khoom siv raw rau cov pob tawb kho cua sov. Ob leeg hlau thiab graphite cov ntaub ntawv muaj cov yam ntxwv ntawm kev siv lub sij hawm ntev kub tsis muaj deformation thiab ruaj khov bearing muaj peev xwm. Lawv yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv lub tshuab nqus tsev sintering furnaces, lub tshuab nqus tsev brazing furnaces, nqus quenching furnaces, thiab lwm yam tshuab nqus tsev kho cua sov industries.
Kev xaiv ntawm cov khoom siv rau lub pob tawb kho cua sov yog nyob ntawm cov yam ntxwv xws li cov txheej txheem kho cua sov (xws li, annealing, normalizing, tempering, nitriding, carburizing), cov khoom siv kho tshuab (xws li, tensile zog, yield point), thiab lub qhov cub tshwj xeeb. hom thiab tsim.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov pob tawb kho cua sov yuav tsum tau hloov ib ntus vim qhov chaw huab cua tsis zoo uas lawv tau raug mus tas li. Nyob rau tib lub sijhawm, pob tawb yuav muaj kev cuam tshuam, sib tw, thiab sagging los ntawm cua sov thiab quenching, qhia tias lawv tau nyob ze rau qhov kawg ntawm lawv lub neej. Qhov nruab nrab, ib lub pob tawb tuaj yeem nyob qhov twg los ntawm rau lub hlis mus rau ob xyoos.
Txhawm rau kom ntev lub neej ntawm cov pob tawb kho cua sov, cov ntaub ntawv ductile wrought tuaj yeem raug txiav txim siab. Cov ntaub ntawv no muaj kev tiv thaiv ntau dua rau thermal qaug zog thiab tuaj yeem pab lub neej ntev ntawm pob tawb. Thaum kawg, kev xaiv cov khoom siv rau lub pob tawb kho cua sov yuav tsum ua raws li cov kev cai tshwj xeeb ntawm cov txheej txheem kho cua sov thiab qhov xav tau lifespan ntawm lub pob tawb.
