Mitundu ya Bell Furnaces

Mwachidule:
Ng'anjo zamtundu wa Bell zimagwiritsidwa ntchito kwambiri pakuwotcha kowala komanso kutentha, motero ndi ng'anjo zapakatikati zomwe zimatentha mosiyanasiyana. Kutentha kumakhala pakati pa 650 ndi 1100 ℃ makamaka, ndipo kumasintha ndi nthawi yotchulidwa mu makina otentha. Kutengera kutsitsa kwa ng'anjo zamtundu wa belu, pali mitundu iwiri: ng'anjo yamtundu wa belu lalikulu ndi ng'anjo yozungulira yamtundu wa belu. Kutentha kwa ng'anjo zamtundu wa belu nthawi zambiri kumakhala gasi, kutsatiridwa ndi magetsi ndi mafuta opepuka. Nthawi zambiri, ng'anjo zamtundu wa belu zimakhala ndi magawo atatu: chivundikiro chakunja, chophimba chamkati, ndi chitofu. The kuyaka chipangizo zambiri anapereka pa kunja chivundikiro insulated ndi matenthedwe wosanjikiza, pamene workpieces anayikidwa mu mkati chivundikirocho Kutentha ndi kuzirala.

Ng'anjo zamtundu wa Bell zimakhala ndi mpweya wabwino, kutentha pang'ono, komanso kutentha kwambiri. Komanso, safuna chitseko cha ng'anjo kapena makina onyamulira ndi njira zina zosiyanasiyana zotumizira, motero amapulumutsa ndalama ndipo amagwiritsidwa ntchito kwambiri m'ng'anjo zochizira kutentha kwa zida zogwirira ntchito.
Zofunikira ziwiri zofunika kwambiri pazida zomangira ng'anjo ndi kulemera kopepuka komanso kugwiritsa ntchito mphamvu zotchingira zotenthetsera.

Mavuto wamba ndi chikhalidwe opepuka refractonjerwa ry kapena opepuka kuponyera Stzopangira zikuphatikizapo:

1. Zipangizo zotsutsa zomwe zimakhala ndi mphamvu yokoka yaikulu (nthawi zambiri njerwa zopepuka zopepuka zimakhala ndi mphamvu yokoka ya 600KG / m3 kapena kuposerapo; zotayira zopepuka zimakhala ndi 1000 KG / m3 kapena kupitilira apo) zimafuna katundu wambiri pamapangidwe achitsulo a chivundikiro cha ng'anjo, kotero zonse zomwe zimagwiritsidwa ntchito ndi zitsulo zopangira zitsulo ndikuwonjezera ndalama zomanga ng'anjo.

2. Chivundikiro chakunja chambiri chimakhudza mphamvu yokweza komanso malo apansi amisonkhano yopanga.

3. Ng'anjo yamtundu wa belu imagwira ntchito pakatentha mosiyanasiyana, ndipo njerwa zopepuka zowoneka bwino kapena zopepuka zopepuka zimakhala ndi kutentha kwakukulu kwapadera, kutenthetsa kwambiri, komanso kugwiritsa ntchito mphamvu zambiri.

Komabe, CCEWOOL refractory fiber fiber imakhala ndi kutsika kwamafuta, kusungirako kutentha pang'ono, komanso kachulukidwe kakang'ono ka voliyumu, zomwe ndizifukwa zazikulu zogwiritsira ntchito kwambiri pazovundikira. Makhalidwe ake ndi awa:

1. Kutentha kosiyanasiyana kogwira ntchito ndi mitundu yosiyanasiyana yofunsira
Ndi chitukuko cha CCEWOOL ceramic CHIKWANGWANI kupanga ndi luso, CCEWOOL ceramic CHIKWANGWANI mankhwala akwaniritsa serialization ndi functionalization. Pankhani ya kutentha, zinthuzo zimatha kukwaniritsa zofunikira za kutentha kosiyanasiyana kuyambira 600 ℃ mpaka 1500 ℃. Pankhani ya morphology, mankhwalawa apanga pang'onopang'ono mitundu yosiyanasiyana yazinthu zachiwiri kapena zozama zopangira kuchokera ku thonje lachikhalidwe, mabulangete, zinthu zomveka kupita ku ma modules a fiber, matabwa, zigawo zooneka bwino, mapepala, nsalu za fiber ndi zina zotero. Amatha kukwaniritsa zofunikira za ng'anjo zamafakitale zopangira zida za ceramic m'mafakitale osiyanasiyana.
2. Kachulukidwe kakang'ono ka voliyumu:
Kachulukidwe wa zinthu za ceramic fiber nthawi zambiri ndi 96 ~ 160kg/m3, pafupifupi 1/3 ya njerwa zopepuka ndi 1/5 ya zopepuka zotayira. Kwa ng'anjo yopangidwa kumene, kugwiritsa ntchito zinthu za ceramic fiber sikungapulumutse zitsulo zokha, komanso kumapangitsanso kutsitsa / kutsitsa ndi kuyendetsa mosavuta, kupititsa patsogolo luso la ng'anjo ya mafakitale.
3. Kutentha kochepa komanso kusungirako kutentha:
Poyerekeza ndi njerwa zomangira ndi njerwa zotsekereza, mphamvu ya zinthu za ceramic fiber ndizotsika kwambiri, pafupifupi 1/14-1/13 ya njerwa zomangira ndi 1/7-1/6 ya njerwa zotsekereza. Kwa ng'anjo yamtundu wa belu yomwe imagwiritsidwa ntchito nthawi ndi nthawi, mafuta ambiri osakhudzana ndi kupanga amatha kupulumutsidwa.
4. Kumanga kosavuta, nthawi yochepa
Monga mabulangete a ceramic fiber ndi ma modules ali ndi elasticity yabwino, kuchuluka kwa kuponderezana kumatha kuneneratu, ndipo palibe chifukwa chosiya zolumikizira zowonjezera pakumanga. Chotsatira chake, ntchito yomangayi ndi yosavuta komanso yosavuta, yomwe imatha kumalizidwa ndi antchito aluso nthawi zonse.
5. Ntchito popanda uvuni
Potengera ulusi wazitsulo zonse, ng'anjo zimatha kutenthedwa msanga ndi kutentha kwa ndondomeko ngati sizikuletsedwa ndi zigawo zina zachitsulo, zomwe zimathandizira kwambiri kugwiritsa ntchito bwino ng'anjo za mafakitale ndi kuchepetsa kugwiritsira ntchito mafuta osagwirizana ndi kupanga.
6. Otsika kwambiri matenthedwe madutsidwe
Ceramic CHIKWANGWANI ndi kuphatikiza ulusi ndi awiri a 3-5um, choncho ali otsika kwambiri matenthedwe madutsidwe. Mwachitsanzo, pamene bulangeti ya aluminiyamu ya fiber yokhala ndi kachulukidwe ka 128kg/m3 ikafika pa 1000 ℃ potentha kwambiri, kutentha kwake kumangokhala 0.22 (W/MK).
7. Kukhazikika kwamankhwala komanso kukana kukokoloka kwa mpweya:
Ulusi wa Ceramic ukhoza kungowonongeka mu phosphoric acid, hydrofluoric acid, ndi alkali yotentha, ndipo imakhala yokhazikika kuzinthu zina zowononga. Kuphatikiza apo, ma module a ceramic fiber amapangidwa ndikupinda mosalekeza mabulangete a ceramic fiber pamlingo wina woponderezedwa. Pambuyo pothandizidwa, kukana kukokoloka kwa mphepo kumatha kufika 30m/s.
