Tempered iav puas tuaj yeem tawg tshwm sim? Tej zaum ntau tus neeg yuav xav tias coj txawv txawv, tempered iav nws tus kheej tawg yog dab tsi? Self-explosion ntawm tempered iav yog hais txog qhov tshwm sim ntawm tsis siv neeg tawg ntawm tempered iav tsis ncaj qha mechanical sab nraud quab yuam. Dab tsi yog qhov ua rau tus kheej tawg ntawm tempered iav? Muaj ntau ntau qhov laj thawj rau kev detonation ntawm tus kheej, uas tuaj yeem ua tiav raws li hauv qab no:
1. Muaj pob zeb, impurities thiab npuas hauv iav: impurities hauv iav yog qhov tsis muaj zog ntawm
tempered iav thiab kuj qhov kev ntxhov siab concentration point. Tshwj xeeb tshaj yog yog lub pob zeb nyob rau hauv lub
tensile stress zone ntawm tempered iav, nws yog ib qho tseem ceeb uas ua rau tawg.
2.Ib iav muaj cov nickel sulfide crystals. Tus kheej tawg ntawm tempered iav yog tshwm sim los ntawm cov
hloov theem transformation ntim ntawm nickel sulphide crystals.
3. Qhov tsis xws luag xws li khawb, blasting qhib thiab sib sib zog nqus tawg npoo yog yooj yim los ntawm imp
roper ua los yog ua haujlwm ntawm iav nto, uas yuav ua rau muaj kev ntxhov siab
concentration lossis self-explosion ntawm tempered iav.
4. Qhov tsis sib xws ntawm kev ntxhov siab, offset lossis kev ntxhov siab ntau dhau hauv cov iav toughened.
Feem ntau hais lus, qhov ua rau thiab cov xwm txheej ntawm tus kheej tawg hauv cov txheej txheem iav tempering
Feem ntau ntawm lawv yog 3 thiab 4, feem ntau yog lawv tus kheej tawg tom qab iav tawm hauv Hoobkas hauv rooj plaub 1 thiab
2, thiab feem ntau ntawm lawv yog cov ntaub ntawv 1 tom qab kev teeb tsa iav tiav.
Yuav ua li cas txheeb xyuas tus kheej tawg ntawm tempered iav?
Qhov txawv ntawm tempered self-explosion thiab cuam tshuam puas ntawm tempered iav yog feem ntau
vim qhov txawv ntawm "pib taw tes". Feem ntau, qhov pib taw tes ntawm tempered iav nws tus kheej tawg yog nyob rau hauv qhov chaw
ntawm iav. Nyob rau hauv nruab nrab ntawm qhov pib taw tes, muaj ib tug ntshiab npauj npaim zoo li
fragment, feem ntau hu ua "butterfly spot".
