Inkcazo

I-Silicon carbide igubu lokusila ithatha inkqubo yokubumba i-isostatic, ubuninzi be-3.09g / cm3, ubuninzi be-φ950mm, ubulukhuni beVickers 2550HV.

i-silicon carbide i-ceramic grinding barrel ekusetyenzisweni kwamandla kunye nokukhuselwa kokusingqongileyo Ukushisa okunengqiqo kwerhasi kwi-silicone carbide umbhobho wokusila we-ceramic unokusetyenziselwa ukuhlambulula igesi ngokuthe ngqo kwiqondo lokushisa eliphezulu. Xa kuthelekiswa nokuhlanjululwa kweqondo lokushisa eliqhelekileyo, ukusebenza kakuhle kwe-thermal kuye kwaphuculwa kakhulu. Ukusetyenziswa ngokuthe ngqo kwerhasi ecociweyo yobushushu obuphezulu kumbane wokuvelisa amandla eijini yerhasi kunokuphucula kakhulu ukusebenza kakuhle kobonelelo lwamandla, ukunciphisa ukukhutshwa kwezinto eziyingozi nokugcina amanzi.

I-silicon ye-carbide yokugaya i-barrel inzuzo

(1) Ukumelana nokushisa okuphezulu, i-coefficient encinci yokwandiswa kwe-thermal
I-silicon carbide yenziwa kumaqondo aphezulu. Kwezinye iimeko zokushisa okuphezulu, izinto ezifunekayo ukuba zibe namandla athile okusebenza, kwaye zihlangabezane nokuchaneka kokucubungula, kunye ne-silicon carbide ceramics inokufezekisa la manqaku mabini. Elona qondo liphezulu lokusetyenziswa kwesilicon carbide limalunga ne-800℃, kwaye iqondo lobushushu lentsimbi lingama-250℃ kuphela. Ngokubala ngokurhabaxa, umndilili wokwandiswa kwe-thermal coefficient ye-SIC yi-4.4×10-6/ C kuluhlu lwe-25 ~ 1400℃. I-coefficient yokwandisa i-thermal ye-SIC incinci kakhulu kunezinye i-abrasives kunye nezixhobo zokushisa eziphezulu. Ngokomzekelo, i-coefficient yokwandiswa kwe-thermal ye-corundum ingaba phezulu njenge (7 ~ 8) × 10-6 / ℃.

(2) Ukuhanjiswa kwe-thermal ephezulu
I-high conductivity ye-thermal ye-SIC yolunye uphawu olubalulekileyo lweempawu zayo zomzimba. I-thermal conductivity ye-silicon carbide iphezulu kakhulu kunezinye izinto eziphikisayo kunye ne-abrasives, malunga namaxesha angama-4 e-corundum. I-Silicon carbide yokwandisa i-thermal coefficient iphantsi, i-thermal conductivity ephezulu, eyenza iimveliso zayo kwinkqubo yokufudumeza kunye nokupholisa phantsi koxinzelelo oluncinci lwe-thermal, ekwayimveliso ye-silicon carbide ukuxhathisa ukothuka kwe-thermal sisizathu esilungileyo.

(3) Ukumelana nokubola
I-silicon carbide ngenxa yendawo yokunyibilika (iqondo lobushushu lokubola), inertia yekhemikhali kunye nokuxhathisa ukothuka kwe-thermal kuphezulu, ingasetyenziselwa iintlobo ngeentlobo zeemveliso ze-silicon carbide zeceramic, njengemveliso ye-ceramic yesithando sokugaya izixhobo, ipleyiti yesilingi kunye ne-sagger, i-zinc yokunyibilikisa kwimizi-mveliso ethe nkqo. i-cylinder distillation furnace enezitena ze-silicon carbide, i-aluminium ye-electrolytic cell linening, i-crucible, imathiriyeli encinci yeziko.

Isicelo sokumelana nokubola

I-1, iindawo ezityibilikayo (itywina lomatshini, ukuthwala impompo yeekhemikhali, ishaft)
2, izixhobo zokutyumza (umdidiyeli, ilitye lokusila lomoya, ilitye lokusila lesanti)
3.Izixhobo zokuvelisa izixhobo zeSemiconductor (iqonga le-XY, i-tray ye-MOCVD, i-ringinging ring, i-wafer chuck)
4. Amacandelo omatshini wokubumba (iinxalenye zomatshini wokubumba ikhamera yekhamera)
Amalungu ama-5 amelana nobushushu (umbhobho otshisayo, iinxalenye zomatshini wokuvavanya ubushushu obuphezulu, intsimbi enyibilikisiweyo yecrucible)
