Ironmaking Blast Furnaces uye Hot-blast Furnaces

Nhanganyaya kune yekutanga insulation chimiro cheanoputika furnaces uye inopisa-kuputika mavira:

Iyo blast furnace imhando yemidziyo inopisa ine chimiro chakaoma. Ndiyo midziyo mikuru yekugadzira simbi uye ine mabhenefiti ekubuda kukuru, kugadzirwa kwakanyanya, uye mutengo wakaderera.
Sezvo tembiricha yekushanda yechikamu chimwe nechimwe chechoto chinoputika chakanyanya, uye chikamu chimwe nechimwe chinoiswa pasi pemagetsi, senge kukweshera uye kukanganiswa kwechaji inodonha, mazhinji eanopisa-pamusoro-soro refractories anoshandisa CCEFIRE yakakwirira tembiricha yemwenje zvidhinha zvinouya nekunyorovesa kwakanyanya pasi pemutoro uye yakanaka high-temp mechanical simba.
Seimwe yemidziyo mikuru yekuwedzera kweiyo blast furnace, hot blast furnace inopa kupisa-kupisa kunopisa kumhepo inoputika kuburikidza nekushandisa kupisa kubva mumoto wefurnace gas combustion uye kupisa kwekuchinja kwechidhinha lattice. Sezvo chikamu chega chega chine maitiro ekupisa kwegasi, kukukurwa kweguruva rinounzwa negasi, uye kupiswa kwegasi rinopisa, zvinopisa zvinopisa pamusoro zvinowanzosarudza CCEFIRE zvidhinha zvinodzivirira chiedza, kongiri isingapise kupisa, zvidhinha zvevhu, uye zvimwe zvinhu zvine simba remuchina.
Kuti uve nechokwadi chakazara chekupisa kwekushisa kwechigadziko chechoto, kutevedzera misimboti yekusarudza tekinoroji yakavimbika, inodhura uye inonzwisisika zvinhu, iyo lining yebasa rinopisa pamusoro pechoto chinoputika uye moto wayo unopisa unopisa unowanzo sarudza zvinhu zvekudzivirira zvine yakaderera thermal conductivity uye kuita kwakanaka kwekudzivirira.
Imwe nzira yechinyakare ndeyekusarudza calcium silicate board zvigadzirwa, zvine iyi chaiyo yekupisa yekupisa chimiro: iyo yakakwirira-aruminiyamu chiedza zvidhinha + silica-calcium mabhodhi maumbirwo ane thermal insulation ukobvu hunosvika 1000mm.

Ichi chinopisa chinopisa chimiro chine zvinotevera kukanganisa mukushandisa:

A. Thermal insulation zvinhu zvine hombe tembiricha conductivity uye urombo kupisa kwemafuta mhedzisiro.
B. Mabhodhi esilicon-calcium anoshandiswa kuseri kwelining layer anogona kuputsika nyore, kuumba maburi mushure mekutyoka, uye kukonzera kurasikirwa kwekupisa.
C. Kurasikirwa kukuru kwekuchengetedza kupisa, zvichiita kuti simba riparare.
D. Mabhodhi e calcium silicate ane mvura yakasimba, ari nyore kuputsika, uye anoita zvisina kunaka mukuvaka.
E. Tembiricha yekushandisa yecalcium silicate board yakadzikira pa600℃
Izvo zvinopisa zvekudzivirira zvishandiswa zvinoshandiswa muchoto chinoputika uye choto chayo chinopisa chinopisa chinoda kuve nekuita kwakanaka kwekushisa kwekushisa. Kunyange zvazvo kupisa kwekushisa kwe calcium silicate board kwakaderera kudarika kwezvidhinha zvinoramba uye kushandiswa kwekushisa kwekushisa kwakagadziridzwa, nekuda kwehurefu hwemuviri wechoto uye madhayamita makuru echoto, calcium silicate boards inoputika nyore nyore panguva yekuvaka nekuda kwebrittleness yavo, zvichiita kuti kusakwana kwemashure kuvhare kwekuvhara uye kusagutsikana kwekugadzirisa. Naizvozvo, kuitira kuti uwedzere kuvandudza kupisa kwemafuta ekudzivirira kwemetalurgical blast furnaces uye hot blast furnaces, CCEWOOL ceramic fiber zvigadzirwa (zvidhinha / mapuranga) zvave zvinhu zvakanakira kuvharisa pazviri.

Kuongororwa kweceramic fiberboards 'tekiniki maitiro:

CCEWOOL ceramic fiberboards inotora yakakwirira-mhando AL2O3 + SiO2 = 97-99% faibha semidziyo yakabikwa, yakasanganiswa neinorganic binders semuviri mukuru uye yakakwirira-temp mafirita uye ekuwedzera. Iwo anoumbwa nekukurudzira uye kupuruzira uye vacuum suction filtration. Mushure mekunge zvigadzirwa zvaomeswa, zvinogadziriswa kuburikidza neakatevedzana ezvishandiso zvemachining kuti apedze maitiro ekugadzirisa, sekucheka, kukuya, uye kuchera kuti ive nechokwadi chekuti mashandiro echigadzirwa uye kurongeka kuri padanho rinotungamira repasirese. Iwo makuru ehunyanzvi maficha anosanganisira:
a. Yakakwirira kemikari kuchena: ine 97-99% yakakwirira-tembiricha oxides yakadai seAl2O3 uye SiO2, iyo inovimbisa kupisa kupisa kwezvigadzirwa. CCEWOOL ceramic fiberboards haingogone chete kutsiva calcium silicate mapuranga sechoto madziro emadziro, asi zvakare kushandiswa zvakananga pane inopisa pamusoro pemadziro echoto kuti vashongedze yakanakisa mhepo inodzivirira kukukurwa.
b. Low thermal conductivity uye yakanaka thermal insulation effects: Nekuti chigadzirwa ichi CCEWOOL ceramic fiber chigadzirwa chakagadzirwa neakakosha inoenderera mberi kugadzirwa, ine kuita zvirinani pane zvechinyakare diatomaceous pasi zvidhinha, calcium silicate board uye mamwe ma composite silicate anotsigira zvinhu mukudzika kwayo kupisa conductivity, zvirinani kuchengetedza kupisa mhedzisiro, uye yakakosha kuchengetedza simba.
c. Simba repamusoro uye riri nyore kushandisa: Zvigadzirwa zvine high compressive uye flexural simba uye hazvisi-brittle zvinhu, saka zvinozadzisa zvizere zvinodiwa zvezvakaoma kumashure lining materials. Iwo anogona kushandiswa mune chero mapurojekiti ekudzivirira ane simba rakawanda rinodiwa, kutsiva kumashure ekumisa zvinhu zvemagumbeze kana zvekunzwa. Zvichakadaro, iyo yakagadziriswa CCEWOOL ceramic fiberboards ine chaiyo geometric dimensions uye inogona kutemwa nekugadziriswa pamadiro. Kuvaka kwacho kuri nyore kwazvo, kunogadzirisa matambudziko ebrittleness, fragility uye yakakwirira yekuvaka kukuvadzwa mwero we calcium silicate board. Vanopfupisa zvikuru nguva yekuvaka uye kuderedza mari yekuvaka.
Muchidimbu, iyo CCEWOOL ceramic fiberboards inogadzirwa nevacuum kuumba haingove neakanakisa emuchina zvivakwa uye chaiwo geometric dimensions, asi zvakare inochengetedza yakanakisa hunhu hwefibrous heat insulation zvinhu. Vanogona kutsiva calcium silicate board uye kuiswa kune insulation minda inoda kuomarara uye kuzvitsigira uye kuramba moto.
