Kev sib xyaw ntawm cov hluav taws xob rau hluav taws xob yog txheeb xyuas los ntawm ob qho tib si sab hauv thiab sab nraud:

Kev sib xyaw ntawm cov hluav taws xob rau hluav taws xob yog txheeb xyuas los ntawm ob qho tib si sab hauv thiab sab nraud:

1. Cov kab hluav taws xob sab saud txuas nrog tsis raug, ua rau muaj qhov nce ntawm tam sim no, lub zog ntau dhau, thiab kub hnyiab.

2. Cov hlau tsis kam yog grounded mus rau muffle tau thiab ib nrab melted.

3. Qhov chaw thauj khoom ntawm cov hlau tsis kam yog loj heev.

4. Cov khoom siv hluav taws xob tiv thaiv yog cov khoom tsis zoo. Thaum lub sij hawm ib txwm siv ntawm lub cub hluav taws xob, vim qhov tsis sib xws ntawm cov hluav taws xob hluav taws xob hluav taws xob los yog lub sij hawm ntev ruaj khov hauv zos overheating thaum siv, oxidation hauv zos yog tshwm sim, uas ua rau muaj qhov tsis kam ntawm qhov no, ua rau muaj kev nce ntxiv hauv zos voltage poob thiab kub. mus rau hauv lub voj voog vicious. Thaum lub sij hawm tsuas yog melting, vim nyob ze ze ntawm ob kawg ntawm lub cub tawg hluav taws xob xaim tom qab melting thiab conductive nyhuv ntawm melted oxide ntawm hluav taws xob cub hluav taws xob hlau, tsim ib tug arc yuav instantly tsim ib tug ntau dua kub, melting ib co. ntawm cov refractory cib ntawm cov hluav taws xob rauv phaj.

Raws li cov xwm txheej saum toj no, peb lub tuam txhab qhia tias cov chaw tsim khoom siv hluav taws xob yuav cov khoom siv hluav taws xob zoo rau cov khoom siv hluav taws xob, uas yog ib txoj hauv kev zoo los ua kom muaj kev pab cuam lub neej thiab kev nyab xeeb. Tsis tas li ntawd, lub qhov cub zoo yog lub sijhawm ua haujlwm rau lub qhov cub tsim nyog rau kev kho cua sov ntawm cov pas nrig thiab cov ncej ntev. Cov qauv ntawm lub qhov cub zoo yog qhov cub lub cev yog qhov sib sib zog nqus cylindrical, thiab cov khoom ua haujlwm tau muab tso rau hauv lub qhov cub los ntawm ib lub crane rau cua sov. Cov roj siv feem ntau yog roj thiab roj roj. Thaum hluav taws xob siv los ua qhov cua sov, nws yog hu ua lub tshuab hluav taws xob zoo. Zoo hom furnaces yog feem ntau ntsia hauv qab lub rooj cob qhia pem teb theem, nrog rau saum toj los yog ib nrab ntawm cov pem teb theem. Cov npe ntawm qhov cub zoo muaj xws li: yuam convection zoo hom rauv, ntuj convection zoo hom rauv, zoo hom roj carburizing rauv, thiab lwm yam.

Cov khoom cua sov ntawm lub qhov cub zoo yuav muaj qhov muag muag, nthuav dav, ntog, thawj zaug sib tsoo thiab sib tshooj, thiab tom qab ntawd fusing (melting) thaum lub sijhawm ua haujlwm ntev. Cov kev daws teeb meem tseem ceeb rau qhov teeb meem no yog:

Ua ntej, txhawm rau tiv thaiv kev sib cuag ntawm cov hluav taws xob hauv hluav taws xob, cov ntaub ntawv cais tawm yuav tsum muab tso rau

Nyias rwb thaiv tsev cov xov hlau ua los ntawm cov ntaub ntawv kub-resistant xws li 95 plooj (porcelain) tuaj yeem siv los tiv thaiv kev sib tshooj. Tshwj xeeb tshaj yog nyob rau ntawm qhov kev hloov pauv ntawm cov txheej cib hauv qhov cub (thaum tso lub qhov cub, qhov sib txawv ntawm 50mm feem ntau yog sab laug ntawm cov cib thiab cov phab ntsa hauv pem hauv ntej thiab nram qab kawg rau kev tig thiab kev teeb tsa ntawm cov hlau tsis kam), cov vuas ceramic yuav tsum ua ntej. padded los yog lub cub hluav taws xob hlau yuav tsum tau them nrog lub raj ceramic (lub raj ceramic yuav tsum raug thawb mus rau qhov kawg). Cov cua kub kub tsis tuaj yeem siv cov nyias nyias ntawm diatomaceous earth bricks sawn nyob rau hauv nruab nrab ntawm lub cub tawg hlau. Vim tias tsis muaj cua sov tsis zoo ntawm diatomaceous lub ntiaj teb cib, lawv tsuas yog siv tau qis dua 900 degree thiab nws yooj yim rau kev tawg thiab deterioration nyob rau hauv kub kub furnaces.

Thib ob, txhawm rau tiv thaiv cov hlau hauv cub hluav taws xob los ntawm softening, collapsing, los yog sagging, kom nws muaj qee lub zog ntawm qhov kub thiab txias.

Ua ntej, nws yog ib qho tsim nyog los tsim cov qauv qhov ntev ntawm lub tshuab hluav taws xob, xws li cov xaim hluav taws xob tsis zoo, thiab xyuam xim rau txoj kab uas hla, suab, thiab suab ntawm cov khoom siv hlau. Kev teeb tsa ntawm cov cua sov yuav tsum nyob ze rau ntawm lub qhov cub hauv ob sab phlu, thiab nws yuav tsum tau muab tso rau ntawm lub cib, nrog rau qhov tsim nyog nthuav dav sab laug. Txoj hauj lwm ntawm tus nuv me me yuav tsum tsim nyog, feem ntau yog ib qho ntawm 400mm thiab 600mm, thiab nws yuav tsum tau muab khi kom ruaj khov kom tsis txhob pw.

Thib peb, cov kab hluav taws xob hluav taws xob nrog lub ntsej muag tawg

Xyuas seb qhov sib txuas me me ntawm lub tshuab hluav taws xob puas ua haujlwm zoo (lub qhov cub sib txuas rau kev txhim kho cov kab hluav taws xob yuav tsum tau ua kom ruaj khov, nias, ntsaws, thiab tsis xoob), thiab siv cov roj vuam lossis hluav taws xob ci los ua kom lub qhov cub hluav taws xob ua ntej rov qab kho nws. thawj cov duab thiab qhov loj me, nrog rau threading lub raj plooj (porcelain tube) tuaj yeem muab tso rau hauv lub plooj (porcelain tube) hauv qhov cub hluav taws xob. Yog tias ob lub plooj (porcelain) siv tib lub sijhawm, qhov kawg ntawm cov hlab plooj (porcelain) yuav tsum tau nruj nreem nias.
