Kho qhov chaw kuaj hluav taws xob rauv tsis ua hauj lwm

 

Lub cev cua sov yuav ua kom mos, o, poob, poob thiab sib tshooj ua ntej, thiab tom qab ntawd fuse (melt) tom qab lub cev cua sov ua haujlwm ntev. Txhawm rau ua kom lub cub tawg hlau muaj qee lub zog ntawm qhov kub thiab txias thiab tiv thaiv softening, vau los yog sagging, qhov loj ntawm lub cub tawg hlau yuav tsum tau tsim ua ntej, xws li kauv kuj xaim, thiab yuav tsum tau them nyiaj mloog mus rau txoj kab uas hla. alloy lub caij, lub suab thiab lub suab txoj kab uas hla ntawm lub kauv. Lub cev cua sov yuav tsum tau muab ntsia ze rau ntawm lub qhov cub hauv ob sab phlu, thiab yuav tsum tau muab tso rau hauv lub cib, tawm hauv qhov chaw kom zoo rau kev nthuav dav. Txoj hauj lwm ntawm tus nuv me me yuav tsum tsim nyog, feem ntau 400 ~ 600mm, thiab nws tuaj yeem ruaj khov los tiv thaiv nws los ntawm kev poob. Tsis tas li ntawd, txhawm rau tiv thaiv kev sib cuag ntawm cov hluav taws xob hauv hluav taws xob, spacers yuav tsum tau siv. Nws tuaj yeem siv los cais cov hlau tsis kam ua los ntawm cov ntaub ntawv kub resistant xws li 95 porcelain los tiv thaiv kev sib tshooj. Tshwj xeeb, kev hloov pauv ntawm cov txheej cib thiab txheej hauv qhov cub (thaum tsim lub cub tawg, feem ntau yog 50mm qhov sib txawv ntawm cov cib thiab cov phab ntsa pem hauv ntej thiab nram qab rau kev tig thiab kev teeb tsa ntawm cov hlau tsis kam), uas yuav tsum yog. pre-padded nrog ceramic chips los yog lub cub hluav taws xob xaim Muab tso rau ntawm lub plooj (porcelain raj yuav tsum tau thawb rau saum). Cov cua kub kub tsis tuaj yeem siv lub ntiaj teb diatomaceous cib saws muab tso rau hauv nruab nrab ntawm lub tshuab hluav taws xob. Vim hais tias diatomaceous lub ntiaj teb cib tsis zoo nyob rau hauv tshav kub tsis kam, lawv tsuas yog siv tau qis dua 900 degree, thiab lawv yooj yim rau yaj thiab deteriorate nyob rau hauv high-temperature furnaces.

 

Rau lub cub hluav taws xob hlau uas zoo li poob qis, xyuas seb qhov sib txuas me me ntawm lub tshuab hluav taws xob puas ua haujlwm (qhov sib txuas ntawm cov hlua hluav taws xob yuav tsum tau ua kom ruaj khov, nias, ntsaws, thiab tsis xoob), thiab lub tshuab hluav taws xob tuaj yeem hloov tau. gas vuam los yog taws ci. Mos, tom qab ntawd rov ua dua nws cov duab qub thiab qhov loj me, thiab muab lub raj plooj (porcelain tube) tso rau hauv lub tshuab hluav taws xob hluav taws xob (ib lub mandrel tuaj yeem hnav hauv cov plooj (porcelain tube)), thiab lwm yam. Yog tias ob lub plooj (porcelain) siv tib lub sijhawm, qhov kawg ntawm cov porcelain hlab. yuav tsum nyob ze ua ke.

 

Lub cev cua sov tuaj yeem ncaj qha welded los kho cov kev sib tsoo dav dav. Rau qhov tawg loj heev, tsis tuaj yeem ncaj, thiab qhov chaw overburned hauv cheeb tsam raug puas tsuaj loj, txoj kev hloov ib feem tuaj yeem siv tau. Nws tsis yog qhov tsim nyog los khawb tag nrho cov teeb vim yog ib feem tsis ua haujlwm. Cov khoom siv, txoj kab uas hla, suab thiab qhov ntev ntawm cov hlau tsis kam rau kev kho vuam yuav tsum ua raws li cov kev cai qub. Cov xaim kho tshiab tshiab yuav tsum tsis txhob muaj qhov tsis xws luag xws li tawg thiab xeb, thiab yuav tsum yog tuab tuab. Thaum siv cov hlau tsis zoo qub, cov hlau tsis zoo yuav tsum tsis txhob muaj qhov tsis sib xws, oxidation corrosion, tawg deformation, aging thiab brittleness.
