Installation Techniques rau Silicon Molybdenum Qws ntawm Hluav Taws Kub Kub Tube:

1. Vertical suspension ntawm silicon molybdenum pas nrig

Kev teeb tsa ntsug ntawm U-puab silicon molybdenum rods raug tshem tawm ntawm lub qhov cub sab saum toj yog qhov zoo tagnrho. Rau qhov cub hluav taws xob nrog lub qhov cub kub siab tshaj 1500 degree, nws raug nquahu kom siv txoj kev teeb tsa ntsug. Thaum ua haujlwm kub, cov khoom yuav muaj elongation thiab me ntsis deformation. Yog li ntawd, nws raug nquahu kom tswj hwm qhov kev ncua deb kom tsis txhob overheating ntawm lub cua sov caij thiab kev sib tsoo ntawm lub qhov cub phab ntsa.

Lub khob hliav qab txuas cov cua sov kawg thiab qhov txias kawg yog nthuav tawm hauv lub qhov cub, nrog rau qhov nrug deb ntawm 25-30mm los ntawm lub qhov cub sab saum toj. Kev sib txuas ntawm qhov kawg txias (nrog rau cov khoom siv ntawm cov cua sov) yuav tsum raug nthuav tawm tsawg kawg yog 75 hli sab nraum lub qhov cub. Qhov dav dav ntawm lub tshuab hluav taws xob cua sov hauv lub tshuab hluav taws xob yuav tsum tsis txhob tsawg dua qhov nruab nrab ntawm qhov hluav taws xob cua sov.

2. Kab rov tav installation ntawm silicon theem pas nrig

Rau cov hluav taws xob furnaces uas muaj qhov kub ntawm lub cub tawg, cov cua sov tuaj yeem ntsia tau rau hauv kab rov tav thiab kab rov tav. Thaum cua sov, qhov kub kawg ntawm silicon molybdenum pas nrig yuav tsum tuaj yeem nthuav tawm dawb, thiab kev txhawb nqa yuav tsum tau muab rau ntawm qhov qis ntawm qhov kub kawg. Silicone refractory khoom uas muaj qhov ntom ntau dua 2.5 g / cm3 thiab cov ntsiab lus hlau tsawg dua 1% tuaj yeem siv. Qhov kub ntawm qhov kub kawg ntawm kab rov tav mounted hluav taws xob rhaub yuav tsum tsis pub tshaj 1600 degree, thiab qhov kub ntawm qhov cub tawg yuav tsum yog 1500 degree. Yog tias qhov kub thiab txias siab dhau lawm, cov silica zaj duab xis ntawm qhov kub kawg saum npoo reacts nrog cov khoom siv refractory thiab khi ua ke. Thaum lub caij txias, tiv thaiv cov hluav taws xob cua sov los ntawm kev cog lus dawb thiab ua rau cov cua sov ua kom puas.

Silicon molybdenum pas nrig hluav taws xob cua sov lub caij yog lub siab kub resistant cua sov caij ua los ntawm molybdenum disilicide. Thaum siv nyob rau hauv qhov kub-kub oxidation cua, lub ci thiab ntom quartz (SIO2) iav zaj duab xis yog tsim rau saum npoo, uas tuaj yeem tiv thaiv txheej sab hauv ntawm silicon molybdenum pas nrig los ntawm oxidation. Kev ua haujlwm ntawm silicon molybdenum pas nrig hluav taws xob cua sov cov ntsiab lus nce nrog qhov nce ntawm qhov kub thiab txias. Thaum qhov kub thiab txias tsis tu ncua, tus nqi kuj tseem ruaj khov. Thaum qhov kub thiab txias, qhov kev tiv thaiv ntawm lub caij tuaj yeem tsis quav ntsej, thiab qhov kev tiv thaiv tsis hloov nrog qhov ntev ntawm kev siv. Cov khoom siv hluav taws xob tshiab thiab qub tuaj yeem sib xyaw rau kev siv.
