Lub qhov rooj rauv tsuas qhib tau thaum qhov kub ntawm lub tshuab nqus tsev kho cua sov cov khoom poob rau 200 degree lossis qis dua

Lub qhov rooj rauv tsuas qhib tau thaum qhov kub ntawm lub tshuab nqus tsev kho cua sov cov khoom poob rau 200 degree lossis qis dua

Thaum siv, qhov cub kub ntawm lub thawv-hom tiv thaiv rauv yuav tsum tsis txhob siab tshaj qhov kub siab, tsis txhob hlawv hluav taws xob, thiab txwv tsis pub txhaj ntau cov kua thiab cov hlau molten rau hauv lub qhov cub.

Tom qab ob peb lub voj voog ntawm cua sov, lub refractory ntawm lub cub hluav taws xob yuav tawg. Cov kab nrib pleb no tshwm sim los ntawm kev nthuav dav thermal thiab tsis cuam tshuam rau qhov zoo ntawm lub tshuab hluav taws xob.

Siv ceev faj thaum siv lub thawv-hom qhov cub kom tiv thaiv tsis ua haujlwm ntawm kev tswj tus kheej thiab ua rau muaj kev sib tsoo, thiab tsis txhob siv lub qhov cub tiv thaiv thaum lawv tsis muaj sijhawm hmo ntuj.

Tom qab siv lub thawv rauv, tua lub hwj chim thiab cia qhov kub thiab txias poob lawm. Tsis txhob qhib qhov cub qhov rooj tam sim ntawd, yog tias muaj qhov xav tau ceev, qhib qhov sib txawv me me ua ntej kom txo qhov kub kom lub qhov cub tsis dheev txias, tawg thiab tawg. Tsuas yog qhib lub qhov cub thaum qhov kub thiab txias yog 200 degree lossis qis dua.

Tsis tas yuav tsum tau sib sau ua ke silicon carbide rods thaum lub tshuab nqus tsev kho cua sov hloov pauv txoj kev sib txuas

Rau cov silicon carbide pas nrig hom rauv, yog tias cov silicon carbide qws pom tias puas lawm, nws yuav tsum tau hloov nrog ib tug tshiab silicon carbide pas nrig nrog rau qhov opposite specification thiab zoo sib xws cov nqi. Thaum hloov, ua ntej tshem tawm ob kawg ntawm lub hau npog thiab cov silicon carbide qws chuck, thiab tom qab ntawd tshem tawm cov silicon carbide qws puas. Txij li cov pas nrig silicon carbide yooj yim tawg, yuav tsum tau saib xyuas thaum lub sijhawm teeb tsa. Qhov chaw ntawm lub cub tawg ntawm ob qhov kawg yuav tsum sib npaug, thiab lub chuck yuav tsum Tighten kom nws nyob rau hauv kev sib cuag zoo nrog silicon carbide pas nrig.

Yog hais tias lub chuck yog oxidized hnyav, nws yuav tsum tau hloov nrog ib tug tshiab. Qhov khoob ntawm cov cuab yeej qhov ntawm ob qhov kawg ntawm silicon carbon pas nrig yog thaiv nrog cov hlua asbestos. Lub qhov cub kub yuav tsum tsis txhob siab tshaj qhov siab tshaj plaws ua haujlwm kub ntawm 1350 degree. Lub silicon carbon V-blender pas nrig tau tso cai ua haujlwm tsis tu ncua rau 4 teev ntawm qhov kub qis tshaj plaws. Tom qab lub tshuab hluav taws xob tau siv rau lub sijhawm ntev, yog tias lub tshuab hluav taws xob hloov hluav taws xob tau hloov kho clockwise mus rau qhov siab tshaj plaws, cov cua sov tam sim no tseem tsis tuaj yeem nce mus. Tus nqi ntxiv ntawm lub tshuab sau ntawv me me yog nyob deb, thiab lub zog cua sov yuav tsum tsis tuaj yeem ua tiav, uas piav qhia tias cov pas nrig silicon carbide tau muaj hnub nyoog.

Lub muffle rauv tsis tas yuav tsum tau nruab nrog silicon carbide rods thaum hloov txoj kev sib txuas, tsuas yog txoj kev sib txuas yuav tsum tau hloov, thiab tom qab hloov txoj kev sib txuas, xyuam xim rau kev hloov kho cua sov lub zog hloov khawm maj mam thaum siv lub cub tawg, thiab cov nqi hluav taws xob tam sim no yuav tsum tsis pub tshaj tus nqi ntxiv.
