Furnace irin nau'in kararrawa

Bayani:
Furnace irin nau'in kararrawa ana amfani da su ne don kawar da zafi da zafi, don haka tanderu masu zafi daban-daban ne. Zazzabi yana tsayawa tsakanin 650 da 1100 ℃ galibi, kuma yana canzawa ta lokacin da aka ƙayyade a tsarin dumama. Dangane da lodi na murhun nau'in kararrawa, akwai nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan kararrawa guda biyu: tanderun nau'in kararrawa mai murabba'i da tanderun nau'in kararrawa. Tushen zafi na tanderun irin kararrawa galibi iskar gas ne, sai wutar lantarki da mai mai haske. Gabaɗaya, tanderun irin kararrawa sun ƙunshi sassa uku: murfin waje, murfin ciki, da murhu. Ana saita na'urar konewa yawanci akan murfin waje wanda aka keɓe tare da Layer na thermal, yayin da ana sanya kayan aikin a cikin murfin ciki don dumama da sanyaya.

Furnace irin nau'in kararrawa suna da kyakyawan matsewar iska, ƙarancin zafi, da ingantaccen yanayin zafi. Haka kuma, ba su bukatar wani tanderu kofa ko dagawa inji da sauran daban-daban inji watsa hanyoyin, don haka sun ceci halin kaka da aka yadu amfani a cikin zafi jiyya tanderu na workpieces.
Biyu mafi mahimmancin buƙatu don kayan rufin tanderun sune nauyi mai sauƙi da ƙarfin ƙarfin murfi na dumama.

Matsalolin gama gari tare da refracto mara nauyi na gargajiyary bulo ko ƙananan nauyi structures sun haɗa da:

1. Refractory kayan tare da babban musamman nauyi (gaba ɗaya na yau da kullum nauyi refractory tubalin da wani takamaiman nauyi na 600KG / m3 ko fiye; m castable yana da 1000 KG / m3 ko fiye) bukatar babban kaya a kan karfe tsarin na tanderun murfin, don haka duka da amfani da karfe tsarin da kuma zuba jari a cikin tanderun gina.

2. Ƙaƙƙarfan murfin waje mai girma yana rinjayar ƙarfin ɗagawa da filin bene na wuraren samar da kayan aiki.

3. An yi amfani da murhun nau'in kararrawa a yanayin zafi daban-daban, kuma bulogin haske ko simintin haske suna da ƙayyadaddun ƙarfin zafi, babban ƙarfin zafi, da kuma yawan amfani da makamashi.

Koyaya, samfuran fiber refractory CCEWOOL suna da ƙarancin ƙarancin zafin jiki, ƙarancin ajiya mai zafi, da ƙarancin girma, waɗanda sune mahimman dalilai na faɗuwar aikace-aikacen su a cikin murfin dumama. Siffofin sune kamar haka:

1. Faɗin zafin jiki na aiki da nau'ikan aikace-aikace daban-daban
Tare da ci gaban CCEWOOL yumbu fiber samar da fasaha, CCEWOOL yumbu fiber kayayyakin sun cimma serialization da kuma aiki. A cikin sharuddan zazzabi, da kayayyakin iya saduwa da bukatun daban-daban yanayin zafi jere daga 600 ℃ zuwa 1500 ℃. Dangane da ilimin halittar jiki, samfuran sannu a hankali sun haɓaka nau'ikan sarrafawa na sakandare daban-daban ko samfuran sarrafawa mai zurfi daga auduga na gargajiya, bargo, samfuran ji zuwa nau'ikan fiber, allon allo, sassa na musamman, takarda, fiber Textiles da sauransu. Suna iya cika buƙatun murhun masana'antu don samfuran fiber yumbu a masana'antu daban-daban.
2. Karamin girma mai yawa:
The girma yawa na yumbu fiber kayayyakin ne kullum 96 ~ 160kg/m3, wanda shi ne game da 1/3 na nauyi tubalin da 1/5 na hur refractory castable. Don sabon tanderun da aka tsara, yin amfani da kayan fiber yumbu ba zai iya ceton karfe kawai ba, har ma ya sa kaya / saukewa da sufuri da sauƙi, yana haifar da ci gaba a cikin fasahar tanderun masana'antu.
3. Ƙananan ƙarfin zafi da ajiyar zafi:
Idan aka kwatanta da tubalin da aka yi amfani da su da tubalin rufi, ƙarfin kayan fiber yumbura ya ragu sosai, game da 1 / 14-1 / 13 na tubalin da aka lalata da 1 / 7-1 / 6 na tubalin rufi. Don tanderun irin kararrawa da ke aiki ta ɗan lokaci, za a iya ajiye yawan adadin man da ba ya da alaƙa da samarwa.
4. Simple yi, gajeren lokaci
Kamar yadda yumbu fiber barguna da kayayyaki suna da kyakkyawan elasticity, adadin matsawa za a iya annabta, kuma babu buƙatar barin haɗin haɓaka yayin gini. A sakamakon haka, ginin yana da sauƙi kuma mai sauƙi, wanda za a iya kammala shi ta hanyar ƙwararrun ma'aikata na yau da kullum.
5. Aiki ba tare da tanda ba
Ta hanyar ɗaukar cikakken rufin fiber, murhun wuta za a iya mai da sauri zuwa zafin jiki idan ba a iyakance shi da sauran abubuwan ƙarfe ba, wanda ke haɓaka ingantaccen amfani da tanderun masana'antu kuma yana rage yawan amfani da mai da ba shi da alaƙa.
6. Ƙarƙashin ƙarancin thermal conductivity
Fiber yumbu hade ne na zaruruwa tare da diamita na 3-5um, don haka yana da ƙarancin ƙarancin zafi. Alal misali, a lokacin da high-aluminum fiber bargo tare da yawa na 128kg/m3 kai 1000 ℃ a zafi surface, da zafi canja wurin coefficient ne kawai 0.22 (W/MK).
7. Kyakkyawan kwanciyar hankali da juriya ga yashwar iska:
Za a iya lalata fiber yumbu a cikin phosphoric acid, hydrofluoric acid, da alkali mai zafi, kuma yana da kwanciyar hankali ga sauran kafofin watsa labarai masu lalata. Bugu da kari, yumbu fiber modules ana yin su ta hanyar ci gaba da naɗewa yumbu fiber barguna a wani matsi rabo. Bayan da aka bi da saman, juriya na zaizayar iska na iya kaiwa 30m/s.
