Yuav ua li cas kho cov hlau tsis kam ntawm lub thawv hom tsis kam rauv?

Rau cov xov hlau uas muaj sagging, nws yog ib qho tsim nyog yuav tsum tau xyuas seb qhov sib txuas ntawm cov hlau puas nyob rau hauv ib txwm muaj, thiab cov txheej txheem ci tuaj yeem hloov tau los ntawm cov roj welding lossis vuam txee. Cia nws soften thiab rov qab mus rau nws qhov loj me thiab zoo li qub, thiab cia nws poob rau hauv lub thawv-hom tsis kam rau hluav taws xob xaim los hnav cov porcelain raj.
Yog tias ob lub raj plooj (porcelain) siv tib lub sijhawm, qhov kawg ntawm cov kav dej porcelain yuav tsum raug kaw. Yog hais tias cov hlau tsis kam nyob rau hauv lub thawv-hom qhov cub tawg, nws tuaj yeem welded ncaj qha. Rau qhov chaw uas tawg loj heev thiab tsis tuaj yeem ncaj nraim, thiab cov khoom uas yog ib nrab overheated thiab puas lawm, cov kev hloov pauv tuaj yeem siv tau.
Vim qhov tsis ua hauj lwm ntawm lub qhov cub hluav taws xob ntawm lub thawv-hom qhov cub, cov ntaub ntawv, txoj kab uas hla, suab, ntev thiab lwm yam ntawm kev kho vuam hlau yuav tsum tau ua raws li cov kev cai qub. Cov hlau tsis muaj zog ntawm lub thawv hloov tshiab-hom hluav taws xob yuav tsum tsis txhob muaj qhov tsis zoo ntawm cov kab nrib pleb, corrosion, thiab lwm yam, thiab yuav tsum tuab thiab zoo ib yam.
Thaum siv cov hlau tsis zoo qub, cov hlau tsis muaj zog yuav tsum tsis txhob pom qhov tsis sib xws, oxidation corrosion, tawg deformation, laus, brittleness, thiab lwm yam, thiab yuav tsum tsis muaj oxidation loj thiab corrosion ntawm cov qub sucker pas nrig.

Kev kho cua sov txheej txheem tom qab vuam

2.Txo qhov hardness ntawm tshav kub-cuam tshuam cheeb tsam.
3. Txhim kho pob txha toughness.
4. Txhim kho kev qaug zog.
5.Rov qab thiab ua kom lub zog tawm los txo qis hauv kev sib sau txias.
6. Txhim kho lub peev xwm los tiv thaiv kev ntxhov siab corrosion
7. Txuas ntxiv tso cov pa phem nyob rau hauv cov hlau ntawm cov hlua hluav taws xob, tshwj xeeb tshaj yog hydrogen, thiaj li ua tau zoo kom tsis txhob ncua qhov tshwm sim ntawm cov kab nrib pleb.
