Silicon carbide thermocouple tube nchebe
Atụmatụ
● Njikwa okpomọkụ nke aluminum a wụrụ awụ bụ njikọ dị mkpa na ụlọ ọrụ nhazi nke aluminom, ya mere ntụkwasị obi nke ngwaọrụ na-achọpụta okpomọkụ dị mkpa karịsịa. A na-eji seramiiki silicon nitride SG-28 mee ihe n'oge dị iche iche dị ka tube nchebe thermocouple.
● N'ihi arụmọrụ ya dị elu nke ọma, ndụ ọrụ nkịtị nwere ike iru ihe karịrị otu afọ.
● E jiri ya tụnyere ígwè nkedo, graphite, carbon nitrogen na ihe ndị ọzọ, silicon nitride agaghị emebi site na aluminom gbazere, nke na-eme ka o doo anya na izi ezi na nghọta nke ịlele okpomọkụ aluminum.
● Silicon nitride ceramics nwere obere wettability na aluminom a wụrụ awụ, na-ebelata mkpa ọ dị maka mmezi oge niile.
● Tupu echichi, lelee nchichi nke nkwonkwo igwe anaghị agba nchara na skru nke igbe nkwụsị.
● Maka ihe nchekwa, ngwaahịa a ga-ekpo ọkụ karịa 400C tupu ejiri ya.
● Iji mee ka ndụ ọrụ nke ngwaahịa ahụ dịkwuo ogologo, a na-atụ aro ka ị na-ehicha ma na-edozi elu mgbe niile kwa ụbọchị 30-40.
Atụmatụ:
Nnukwu okpomọkụ na-eguzogide: Igwe mkpuchi mkpuchi silicon carbide nke a na-agbanye n'ike nwere ike ịrụ ọrụ ruo 2800 ° F (1550 ° C), na-eme ka ha dabara maka ọtụtụ ngwa mmepụta ihe na-ekpo ọkụ.
Mkpuchi glaze dị n'elu: A na-ekpuchi mpụta ya na silicon carbide glaze pụrụ iche nke na-ebelata porosity ma na-ebelata mpaghara mmeghachi omume na ọla gbazere, si otú ahụ na-agbatị ndụ ọrụ nke tube nchebe.
Nguzogide corrosion na nguzogide ujo: tube nchebe nwere ezigbo nguzogide corrosion, ọkachasị mgbe enwere kọntaktị na aluminom gbazere, zinc na ọla ndị ọzọ, ma nwee ike iguzogide mbibi slag nke ọma. Tụkwasị na nke ahụ, nkwụsi ike ọkụ ọkụ ya dị mma na-eme ka nkwụsi ike nhazi n'oge mgbanwe okpomọkụ ngwa ngwa.
Obere porosity: The porosity bụ naanị 8% na njupụta dị elu, nke na-eme ka nguzogide ya na corrosion kemịkal na ike arụ ọrụ.
Nkọwa dị iche iche: A na-enweta ya n'ogologo dị iche iche (12 "ruo 48") na dayameta (2.0" OD), enwere ike ịkwado ya na 1/2" ma ọ bụ 3/4" NPT threaded njikọ iji gboo mkpa nrụnye akụrụngwa dị iche iche.
Ngwa:
Usoro ịgbaze Aluminom: Isostatically pressed silicon carbide protection tube dị nnọọ mma maka ojiji na aluminom gbazee, yana mgbochi oxidation na ihe ndị dị elu nke okpomọkụ na-agbatị ndụ ọrụ nke thermocouple nke ọma.
Igwe ọkụ ụlọ ọrụ dị elu: N'ime ọkụ ọkụ dị elu ma ọ bụ gburugburu gas na-emebi emebi, tubes mkpuchi silicon carbide nke isostatic na-enye nchebe ogologo oge iji hụ na arụ ọrụ a pụrụ ịdabere na ya nke thermocouples na gburugburu ebe siri ike.
Uru ngwaahịa:
Gbatịa ndụ thermocouple ma belata ugboro nnọchi
Ọkachamara thermal conductivity, melite nha nha okpomọkụ
Ike n'ibu pụtara ìhè, nguzogide nrụgide na nguzogide eyi
Ọnụ ego mmezi dị ala, kwesịrị ekwesị maka ịrụ ọrụ ogologo oge dị elu nke okpomọkụ
Isostatic silicon carbide thermocouple tubes nchebe bụ ezigbo nhọrọ maka nleba ọnọdụ okpomọkụ nke ụlọ ọrụ ọgbara ọhụrụ n'ihi ọmarịcha arụmọrụ na ịdịte aka ha. A na-eji ha eme ihe na mpaghara okpomọkụ dị elu dị ka nkedo, metallurgy, ceramics, na mmepụta iko.
