Kev ceev faj rau kev ua haujlwm nyab xeeb ntawm hlau melting rauv

1. Kev npaj ua ntej qhib lub qhov cub

(1) Tshawb xyuas qhov cub hauv ob sab phlu. Thaum lub thickness ntawm lub cub tawg (tsis suav asbestos phaj) tsawg dua 65-80 hli tom qab hnav, lub qhov cub yuav tsum tau kho;

(2) Tshawb xyuas cov kab nrib pleb. Cov kab nrib pleb saum 3 hli yuav tsum tau ntim nrog cov khoom siv hauv cov khoom siv rau kev kho;

(3) xyuas kom meej tias cov dej txias tsis thaiv.

2. Noj cov lus qhia

Tom qab muab tso rau hauv lub cub tawg, xyuas seb lub cub tawg puas tau muab tso rau hauv qab ntawm lub cub tawg;

Tsis txhob cia cov dej ntub dej hauv qhov chaw kawg, tom qab muab cov nqi qhuav, muab cov khoom ntub tso rau saum nws, thiab siv txoj kev ziab los ntawm cov cua sov hauv qhov cub kom evaporate cov dej ua ntej furnaceization;

Chips yuav tsum tau muab tso rau ntawm cov hlau molten tshuav tom qab tapping kom ntau li ntau tau. Tus nqi ntawm cov tswv yim ntawm ib lub sij hawm tsawg tshaj li ib feem kaum ntawm qhov cub, thiab nws yuav tsum sib npaug;

(4) Tsis txhob ntxiv tubular lossis hollow nqi. Qhov no yog vim qhov nthuav dav ntawm huab cua, uas tej zaum yuav muaj kev phom sij ntawm kev tawg;

(5) Txawm li cas los xij, muab tso rau hauv cov yaj tom ntej ua ntej tus nqi kawg yuav yaj.

(6) Yog tias koj siv tus nqi nrog ntau xeb thiab xuab zeb, lossis ntxiv cov nqi txias ntau dhau ntawm ib zaug, “txhim kho” yooj yim tshwm sim, thiab cov kua theem yuav tsum tau soj ntsuam ntau zaus kom tsis txhob “bridging”, qhov qis dua. molten hlau yuav overheat, ua rau lub hauv ob sab phlu Lub corrosion, txawm to ntawm molten hlau.

3. Kev tswj ntawm molten hlau kub hauv cov hlau melting rauv

Qhov kub ntawm tapping yuav tsum tsis txhob tshaj tus nqi yuav tsum tau. Siab kub molten hlau heev txo lub neej ntawm lub cub tawg hauv ob sab phlu. Raws li cov kua qaub rau hauv ob sab phlu nce mus txog 1500 ° C, nws yog nqa tawm sai heev, thiab cov muaj pes tsawg leeg ntawm cov hlau molten kuj hloov. Cov roj carbon ntsiab lus kub hnyiab thiab cov ntsiab lus silicon nce.
