Graphite Crucible Melting Kub nrog Spout

Graphite crucible melting kub nrog spout yog cov cuab yeej tseem ceeb rau ntau yam kev lag luam uas koom nrog cov ntawv thov kub. Cov crucibles no yog tsim los ntawm cov khoom siv graphite zoo, ua rau lawv ruaj khov thiab ruaj khov, ua kom ntseeg tau kev ua tau zoo, thiab ua tau zoo rau cov kev lag luam sib txawv.
Graphite crucible melting kub nrog spout yog dav siv nyob rau hauv kev lag luam kub thiab hniav nyiaj hniav kub raws li lawv zoo tagnrho rau melting thiab casting ntau yam hlau thiab alloys, xws li kub, nyiaj, platinum, thiab tooj liab. Lawv kuj tau muab rau hauv kev lag luam kho hniav rau melting hniav alloys thiab ceramics. Melting kub graphite crucibles tau dhau los ua cov cuab yeej siv dav hauv kev lag luam foundry, uas lawv tau siv los yaj thiab cam khwb cia hlau thiab hlau.
Sib nrug los ntawm lawv cov kev siv dav hauv ntau qhov kev lag luam uas tau hais los saum toj no, cov crucibles no tseem pom cov ntawv thov hauv cov chaw soj nstuam uas ua cov kev ntsuas kub kub, kev tshawb fawb tshuaj, thiab tsim cov ntaub ntawv tshiab. Vim tias lawv muaj peev xwm tiv taus qhov kub thiab txias, lawv zoo tagnrho rau kev tshuaj xyuas cov ntaub ntawv thiab tsim cov ntawv thov tshiab.

Crucible cua sov hloov mus qeeb
1. Ua tsis tau preheat thiab ci lub lauj kaub qab zib raws li cov txheej txheem txheej txheem;
2. Slag accumulation adheres rau sab hauv phab ntsa ntawm lub crucible;
3. Lub crucible tau mus txog qhov kawg ntawm nws lub neej ua haujlwm

Oxidation ceev heev
1. Kev ua haujlwm tsis tu ncua thaum lub sijhawm hoisting lossis txav tau ua rau muaj kev puas tsuaj rau txheej glaze;
2. Nyob rau hauv lub qhov hluav taws xob tiv thaiv, tsis muaj cov xaim hluav taws xob los yog cov hlua khi rau saum lossis hauv qab ntawm lub crucible;
3. Nyob rau hauv lub cub tawg, lub qhov ncauj ntawm lub crucible tsis muaj nplaim taws los thaiv cov pa oxygen thiab raug ncaj qha rau huab cua;
4. Nyob rau hauv lub cub tawg, cov nplaim hluav taws ncaj qha cuam tshuam rau hauv qab ntawm lub crucible;
5. Qhov kub ua haujlwm siab dhau lawm.

Ntws rau hauv nruab nrab lossis hauv qab
1. Thaum lub hauv paus tsis siv:
2. Lub crucible tsis zoo ntsia thiab yuav tsum tau muab tso rau hauv nruab nrab ntawm lub cub tawg lub cev thiab khaws qib nrog lub hauv paus;
3. Muaj slag txuam los yog residual molten hlau nyob rau hauv lub crucible;
4. Cov khoom siv hlau ntxiv tag nrho, lossis cov hlau ingot muab tso rau hauv kab rov tav lossis diagonally hauv lub crucible;
5. Kev puas tsuaj rau tib neeg thaum lub sijhawm ua haujlwm;
6. Muaj qhov sib txawv ntawm qhov kub thiab txias hauv lub tshuab ua kom sov.

Lub crucible tawg
1. Cov khoom siv graphite crucible tsis muaj cov khoom uas tuaj yeem ua rau tawg, yog li qhov tawg ntawm lub crucible yog feem ntau tshwm sim los ntawm cov khoom ua kom ntub dej lossis cua sov sai heev;
2. Lub graphite crucible tau ua kom ntub thiab qhov kub thiab txias nce ceev heev thaum cua sov;
3. Cov khoom siv hlau ntxiv thaum ua haujlwm tsis qhuav tag;
4. Qhov kub nce ceev heev thaum lub sij hawm preheating.

Crucible corrosion
1. Ntxiv flux thaum lub crucible yog npliag los yog cov hlau tsis yaj tag;
2. Kev siv dej ntau dhau;
3. Qee qhov fluxes yog corrosive heev;
4. Cov roj siv muaj cov khoom corrosive;
5. Lub sij hawm ntev ua haujlwm tsis zoo ntawm qhov kub thiab txias yuav ua rau melting ntawm crucible glaze txheej zoo li corrosion.

Qhov ncauj rupture
1. Muaj cov slag tuab heev ntawm lub qhov ncauj ntawm lub crucible, los yog muaj slag tsub zuj zuj nyob rau hauv qhov sib txawv ntawm lub qhov ncauj thiab lub cub tawg lub nplhaib;
2. Lub qhov ncauj ntawm lub crucible yog oxidized sai heev;
3. Cov khoom noj khoom haus hits lub qhov ncauj ntau zaus;
4. Lub qhov ncauj yog nyob rau hauv kev sib cuag nrog hlau nrog loj tshav kub hloov coefficients xws li hlau.
