Mavira emhando yebhero

Pfupiso:
Mafuro emhando yebell anonyanya kushandiswa pakupisa nekupisa, saka anodziya zvakasiyana-siyana panguva nenguva. Kupisa kunogara pakati pe650 ne1100 ℃ kazhinji, uye kunochinja nenguva yakatarwa musystem yekupisa. Zvichibva pakuiswa kwefuro remhando yebell, kune mhando mbiri: furnace yemhando yebell ine sikweya uye furnace yemhando yebell yakatenderera. Manyuko ekupisa emafuro emhando yebell anonyanya kuve gasi, achiteverwa nemagetsi nemafuta mashoma. Kazhinji, mafuro emhando yebell ane zvikamu zvitatu: chifukidziro chekunze, chifukidziro chemukati, uye chitofu. Mudziyo wekupisa unowanzoiswa pachifukidziro chekunze chakadzivirirwa nethermal layer, nepo maworkpiece achiiswa muchifukidziro chemukati kuti chidziye uye chitonhodze.

Maovheni emhando yebell ane mhepo yakasimba, haapise kupisa zvakanyanya, uye haadi kupisa kwakanyanya. Uyezve, haadi gonhi reovheni kana nzira yekusimudza uye dzimwe nzira dzakasiyana-siyana dzekutumira michina, saka anochengetedza mari uye anoshandiswa zvakanyanya mumaovheni ekupisa ezvishandiso zvebasa.
Zvinhu zviviri zvinonyanya kukosha pakugadzira jira remuchoto huremu hushoma uye kushanda zvakanaka kwesimba rezvivharo zvekupisa.

Matambudziko akajairika ne refracto yechinyakare ine huremu hwakarerukazvidhinha zveRy kana st inoreruka inokandwazvivakwa zvinosanganisira:

1. Zvinhu zvinoramba simba zvine simba guru rekukweva (zvidhinha zvinoramba simba rekare rinosvika 600KG/m3 kana kupfuura; zvinoramba simba rekare rinosvika 1000 KG/m3 kana kupfuura) zvinoda mutoro mukuru pachimiro chesimbi chechoto, saka kushandiswa kwechimiro chesimbi pamwe nekudyara mari mukuvaka choto kunowedzera.

2. Chifukidziro chekunze chakakura chinokanganisa kugona kwekusimudza uye nzvimbo yepasi pemashopu ekugadzira.

3. Choto chemhando yebhero chinoshandiswa pakupisa kwakasiyana-siyana, uye zvidhinha zvidiki zvinoramba kupenya kana kuti zvinokwanisa kupiswa zvine simba guru rekupisa, zvinokwanisa kupisa zvakanyanya, uye zvinoshandisa simba rakawanda.

Zvisinei, zvigadzirwa zveCCEWOOL refractory fiber zvine conductivity yakaderera yekupisa, kuchengetedza kupisa kwakaderera, uye huwandu hwakaderera hwevhoriyamu, izvo zviri zvikonzero zvikuru zvekushandiswa kwazvo mumachira ekupisa. Hunhu hwazvo ndehunotevera:

1. Tembiricha yakakura uye mafomu akasiyana-siyana ekushandisa
Nekuvandudzwa kwekugadzirwa kweCCEWOOL ceramic fiber uye tekinoroji, zvigadzirwa zveCCEWOOL ceramic fiber zvakawana serialization uye functionalization. Panyaya yekupisa, zvigadzirwa zvinogona kusangana nezvinodiwa zvetembiricha dzakasiyana kubva pa600 ℃ kusvika 1500 ℃. Panyaya yemaumbirwo, zvigadzirwa zvakagadzira zvishoma nezvishoma mhando dzakasiyana dzezvigadzirwa zvekugadzirisa kana zvekugadzirisa zvakadzama kubva padonje rechinyakare, magumbeze, zvigadzirwa zvefelt kusvika kumamodule efiber, mabhodhi, zvikamu zvakaumbwa zvakasiyana, bepa, machira efiber nezvimwewo. Zvinogona kusangana zvizere nezvinodiwa zvemaindasitiri ezvigadzirwa zveceramic fiber mumaindasitiri akasiyana-siyana.
2. Kuwanda kwevhoriyamu diki:
Huwandu hwezvinhu zvakagadzirwa nefiber yeceramic hunowanzova 96 ~ 160kg/m3, inova chikamu chimwe chete kubva muzvitatu zvezvidhinha zvakareruka uye chikamu chimwe chete kubva muzvishanu zvezvidhinha zvinoreruka zvinokandwa. Kune choto chitsva chakagadzirwa, kushandiswa kwefiber yeceramic hakungogone kuchengetedza simbi chete, asiwo kunoita kuti kurodha/kuburitsa zvinhu uye kutakurwa zvive nyore, zvichikurudzira kufambira mberi kwetekinoroji yechoto cheindasitiri.
3. Kukwanisa kupisa kudiki uye kuchengetera kupisa:
Zvichienzaniswa nezvidhinha zvinoramba kushanda uye zvinodzivirira kupisa, kugona kwezvigadzirwa zve ceramic fiber kwakaderera zvikuru, inenge 1/14-1/13 yezvidhinha zvinodzivirira kupisa uye 1/7-1/6 yezvidhinha zvinodzivirira kupisa. Kune vira remhando yebhero rinoitwa nguva nenguva, huwandu hwakawanda hwemafuta hunoshandiswa hunogona kuchengetedzwa.
4. Kuvaka kuri nyore, kwenguva pfupi
Sezvo magumbeze eceramic fiber nemamodules aine kutwasuka kwakanaka, huwandu hwekudzvanywa hunogona kufanotaurwa, uye hapana chikonzero chekusiya majoini ekuwedzera panguva yekuvaka. Nekuda kweizvozvo, kuvaka kuri nyore uye kunogona kuitwa nevashandi vane hunyanzvi.
5. Kushanda pasina ovheni
Nekushandisa jira rakazara nefiber, maovheni anogona kukurumidza kupiswa kusvika patembiricha yekushanda kana asina kuganhurirwa nezvimwe zvikamu zvesimbi, izvo zvinovandudza zvikuru kushandiswa kwakanaka kwemaovheni emaindasitiri uye zvinoderedza kushandiswa kwemafuta kusingasanganisirwe nekugadzira.
6. Kupisa kwakaderera zvakanyanya
Ceramic fiber musanganiswa wefibers ine dhayamita ye3-5um, saka ine thermal conductivity yakaderera. Semuenzaniso, kana jira re fiber realuminium rakakwirira rine density ye128kg/m3 rasvika 1000℃ panzvimbo inopisa, coefficient yayo yekufambisa kupisa inongova 0.22(W/MK) chete.
7. Kugadzikana kwakanaka kwemakemikari uye kuramba kukanganiswa nekukukurwa kwemhepo:
Ceramic fiber inogona kungobviswa mu phosphoric acid, hydrofluoric acid, uye hot alkali chete, uye inogara yakagadzikana kune dzimwe nzira dzinoparadza. Pamusoro pezvo, ceramic fiber modules inogadzirwa nekupeta magumbeze e ceramic fiber nguva dzose pane imwe compression ratio. Mushure mekunge pamusoro pagadziriswa, resistance yemhepo inogona kusvika 30m/s.
