Bell-mhando Furnaces

Muchidimbu
Mabhero emhando yeBell anonyanya kushandiswa kupenya uye kupisa kurapwa, saka iwo anopindirana akasiyana-tembiricha mavira. Tembiricha inogara iri pakati pe650 ne1100 ℃ kazhinji, uye inoshanduka nenguva yakatsanangurwa mukudziya system. Zvichienderana nekurodha kwemabhero emhando yehuni, kune marudzi maviri: sikweya bhero-mhando yevira uye yeraundi bhero-mhando yevira. Iko kupisa kunopisa kwemabhero-mhando yevira kazhinji gasi, inoteverwa nemagetsi nemafuta akareruka. Kazhinji, bhero-mhando yevira ine zvikamu zvitatu: chivharo chekunze, chivharo chemukati, uye chitofu. Chishandiso chekupisa chinowanzoiswa pachivharo chekunze chakavharidzirwa nehuturu hwekupisa, nepo ma workpiece anoiswa muvharo yemukati yekudziya uye kutonhora.

Masimbi emhando yeBell ane kusimba kwemweya kwakanaka, kurasikirwa nekupisa kwakaderera, uye kunyatsoshanda kwemafuta. Zvakare, ivo havadi musuwo wechoto kana nzira yekusimudza uye mamwe akasiyana emakanika ekutapurirana michina, saka vanochengetedza mari uye anoshandiswa zvakanyanya mumoto wekupisa wekupisa wezvishandiso.
Zviviri zvinonyanya kukosha zvemidziyo yekubikira yevira uremu huremu uye kushanda nesimba kwemavhavha ekudziya.

Matambudziko akajairika ane yechinyakare lightweight refractory zvidhinha kana lightweight castable Structures dzinosanganisira:

1. Refractory zvinhu zvine yakakura chaiyo giravhiti (kazhinji anogara akareruka refractory zvidhinha zvine chaiyo giravhiti ye600KG/m3 kana kupfuura; lightweight castable ine 1000 KG/m3 kana kupfuura) inoda mutoro wakakura pane chimiro chesimbi chechivharo chechoto, saka zvese kudyiwa kwesimbi chimiro uye kuisirwa kwekuvaka muchoto kunowedzera.

2. Chifukidziro chekunze chakakura chinokanganisa simba rekusimudza uye nzvimbo yepasi yemashopu ekugadzira.

3. Iyo bhero-mhando yevira inoshandiswa panguva dzakasiyana-siyana tembiricha, uye zvidhinha zvinoreruka kana zvinokandwa zvinokandwa zvine hombe chaiyo yekupisa, yakakwirira yekupisa conductivity, uye simba guru rekushandisa.

Nekudaro, CCEWOOL refractory fiber zvigadzirwa zvine yakaderera yekupisa conductivity, yakaderera kupisa kwekuchengetedza, uye yakaderera vhoriyamu density, zvinova zvikonzero zvakakosha zvekushandisa kwavo kwakakura mumavharo ekudziya. Maitiro acho ndeaya anotevera:

1. Yakakura yekushanda tembiricha siyana uye akasiyana mafomu ekushandisa
Nekuvandudzwa kweCCEWOOL ceramic fiber kugadzira uye tekinoroji, CCEWOOL ceramic fiber zvigadzirwa zvakawana serialization uye kushanda. Panyaya yetembiricha, zvigadzirwa zvinogona kusangana nezvinodiwa zvetembiricha dzakasiyana kubva pa600 ℃ kusvika 1500 ℃. Panyaya ye morphology, zvigadzirwa zvishoma nezvishoma zvakagadzira zvakasiyana-siyana zvechipiri zvekugadzirisa kana zvakadzika zvigadzirwa zvekugadzira kubva kukotoni yechinyakare, magumbeze, anonzwa zvigadzirwa kune fiber modules, mabhodhi, akakosha-akaumbwa zvikamu, mapepa, fiber machira zvichingodaro. Ivo vanogona kuzadzisa zvizere zvinodikanwa zvemaindasitiri evira zveceramic fiber zvigadzirwa mumaindasitiri akasiyana.
2. Diki volume density:
Huwandu hwehuwandu hwezvigadzirwa zveceramic fiber zvinowanzoita 96 ~ 160kg/m3, inenge 1/3 yezvidhinha zvisingaremi uye 1/5 yezvakareruka zvinokandwa. Nokuda kwechoto chichangobva kugadzirwa, kushandiswa kwezvigadzirwa zveceramic fiber hazvigoni kuchengetedza simbi chete, asiwo kuita kuti kurodha / kurodha uye kutakura zviri nyore, zvichiita kuti kufambira mberi mune tekinoroji yechoto.
3. Kupisa kudiki uye kuchengetedza kupisa:
Zvichienzaniswa nezvidhinha zvinoramba uye zvidhinha zvekudzivirira, simba rezvigadzirwa zveceramic fiber rakaderera zvikuru, inenge 1/14-1/13 yezvidhinha zvinoramba uye 1/7-1/6 yezvidhinha zvekudzivirira. Kune iyo inopindirana inoshandiswa bhero-mhando yevira, huwandu hwakawanda hwehusina kugadzirwa-hune chekuita nemafuta hunogona kuchengetedzwa.
4. Kuvaka nyore, nguva pfupi
Sezvo ceramic fiber magumbeze uye ma module ane yakanakisa elasticity, huwandu hwekumanikidza hunogona kufanotaurwa, uye hapana chikonzero chekusiya majoini ekuwedzera panguva yekuvaka. Somugumisiro, chivakwa chacho chiri nyore uye chiri nyore, chinogona kupedzwa nevashandi venguva dzose vane unyanzvi.
5. Kushanda pasina ovheni
Nekugamuchira iyo yakazara-fiber lining, mavira anogona kukurumidza kupisa kune tembiricha yemaitiro kana asina kuganhurirwa nezvimwe zvikamu zvesimbi, izvo zvinovandudza zvakanyanya kushandiswa kunoshanda kwehuni dzemaindasitiri uye kuderedza kusiri kwekugadzira-kwakanangana nekushandiswa kwemafuta.
6. Kunyanya kuderera kwekushisa conductivity
Ceramic fiber isanganiswa yemafiber ane dhayamita ye3-5um, saka ine yakaderera kwazvo yekupisa conductivity. Semuenzaniso, kana yakakwira-aluminum fiber gumbeze ine density ye128kg/m3 inosvika 1000 ℃ pakupisa kwepamusoro, kupisa kwayo kwekutamisa coefficient ingori 0.22 (W/MK).
7. Kugadzikana kwakanaka kwemakemikari uye kuramba kukukurwa kwemhepo:
Ceramic fiber inogona kungobviswa mu phosphoric acid, hydrofluoric acid, uye inopisa alkali, uye yakagadzikana kune mamwe ma media anoparadza. Uye zvakare, iyo ceramic fiber modules inogadzirwa nekuramba ichipeta ceramic fiber magumbeze pane imwe compression ratio. Mushure mekurapwa kwepamusoro, mhepo inodzivirira kuvhuvhuta inogona kusvika 30m/s.
