Refractory Castables For Cement Rotary Kiln

Refractory Castables For Cement Rotary Kiln

1. Simbi faibha yakasimbisa refractory castables ye simende kil
Simbi fiber yakasimbiswa inokandwa inonyanya kuunza kupisa-inodzivirira Stainless simbi faibha mukati mechinhu, kuitira kuti zvinhu zvive nesimba repamusoro uye nekupisa kwekusagadzikana kwekushisa, nekudaro zvichiwedzera kusakara uye hupenyu hwebasa rezvinhu. Izvo zvinhu zvinonyanya kushandiswa kune yakakwirira-tembiricha inodzivirira kupfeka-inodzivirira zvikamu senge honi muromo, muromo wekudya, kupfeka-inodzivirira pier uye magetsi ekudyara boiler lining.

2. Low simende refractory castables for simende kil
Yakaderera simende refractory castables inonyanya kusanganisira yakakwirira-alumina, mullite uye corundum refractory castables. Iyi nhevedzano yezvigadzirwa ine hunhu hwekusimba kwepamusoro, anti-scouring, kupfeka kuramba uye kuita kwakanakisa. Panguva imwecheteyo, zvinyorwa zvinogona kugadzirwa mukukurumidza-kubika kuputika-proof castables zvinoenderana nemushandisi nguva yekubheka zvinodiwa.

3. High-simba alkali-resistant castables for simende kil
High-simba alkali-resistant castables vane kurwisa kwakanaka kwekukukurwa nemagasi ealkaline uye slag, uye vane hupenyu hurefu hwebasa. Ichi chinyorwa chinonyanya kushandiswa kuvhavha yegonhi remoto, mafivha ekuora, preheater masisitimu, manejimendi masisitimu, nezvimwewo uye mamwe mabikisheni emaindasitiri.

Nzira yekuvaka yepamusoro-aluminium yakaderera-simende inokandwa ye rotary kiln lining
Kuvakwa kwepamusoro-aluminium yakaderera-simende inokandwa yerotary kiln lining inoda kutarisisa kune anotevera maitiro mashanu:

1. Kutsunga kwemajoini ekuwedzera
Kubva pane zvakaitika kare zvekushandisa high-aluminium low-cement castables, majoini ekuwedzera chinhu chinokosha chinokanganisa hupenyu hwebasa re rotary kiln castable linings. Iwo majoini ekuwedzera panguva yekudururwa kweiyo rotary kiln linings inotemwa sezvinotevera:

(1) Circumferential majoini: 5m zvikamu, 20mm aluminium silicate fiber inonzwa iri sandwiched pakati pezvinokandwa, uye mafiber akaumbwa mushure mekuwedzera kuti avhare kushushikana kwekuwedzera.

(2) Majoini akafuratira: Mitsetse mitatu yega yega inokandwa inoiswa sandwich ne 100mm yakadzika plywood mukati memukati circumferential gwara, uye mubatanidzwa unosiiwa kumagumo ekushanda, kwehuwandu hwematanho matanhatu.

(3) Panguva yekudira, mapini makumi maviri neshanu emhepo anoshandiswa paskweya mita kuburitsa imwe huwandu hwekushushikana kwekuwedzera uku uchipedza honi.

2. Kutsunga kwekushisa kwekuvaka
Iyo yakakodzera tembiricha yekuvaka yepamusoro-aluminium yakaderera-simende castables ndeye 10 ~ 30 ℃. Kana iyo ambient tembiricha yakadzikira, matanho anotevera anofanira kutorwa:

(1) Vhara nharaunda yekuvaka yakatenderedza, wedzera zvivakwa zvekudziisa, uye kudzivirira zvakanyanya kutonhora.

(2) Shandisa mvura inopisa pa35-50 ℃ (yakatemerwa neiyo-saiti yekudurura bvunzo vibration) kusanganisa izvo zvinhu.

3. Kusanganisa
Sarudza huwandu hwekusanganiswa panguva imwe zvichienderana nekugona kwemusanganisi. Mushure mekunge huwandu hwekusanganiswa hwatemerwa, wedzera iyo yekukanda zvinhu mubhegi uye diki pasuru yekuwedzera mubhegi mumusanganisi panguva imwe chete. Kutanga tanga musanganisi kuti uome-sanganisa kwemaminetsi maviri-3, wobva wawedzera 4/5 yemvura yakayerwa kutanga, simbisa kwemaminetsi maviri-3, uye wobva waona yasara 1/5 yemvura maererano nekupenya kwedhaka. . Mushure mekusanganisa zvizere, kudururwa kwebvunzo kunoitwa, uye huwandu hwemvura hwakawedzerwa hunotarwa pamwe chete nekudengenyeka uye slurry mamiriro. Mushure mekunge huwandu hwemvura yakawedzerwa hunotarwa, hunofanira kunyatsodzorwa. Ndichiri kuona kuti slurry inogona kuzunguzika, semvura shoma sezvinobvira inofanirwa kuwedzerwa (iyo inotaridzirwa mvura yekuwedzera huwandu hweiyo inokandwa i5.5% -6.2%).

4. Kuvaka
Nguva yekuvaka ye-high-aluminium low-cement castable inenge maminitsi makumi matatu. Zvinhu zvakasvibiswa kana kuti zvakasvibiswa hazvigoni kusanganiswa nemvura uye zvinofanira kuraswa. Shandisa tsvimbo inozunguza kubvunda kuti uwane slurry compaction. Chimuti chinozunguzika chinofanirwa kuchengetedzwa kudzivirira kuti spare rod isabatike kana chitanda chinozunguzika chatadza kushanda.
Kuvakwa kwezvinhu zvinokandwa kunofanirwa kuitwa mumitsetse pamwe neaxis yehuni inotenderera. Pamberi pekudururwa kwega kwega, nzvimbo yekuvaka inofanira kucheneswa uye hapana guruva, welding slag uye mamwe marara anofanira kusiiwa. Panguva imwecheteyo, tarisa kana iyo welding yeanchor uye yepamusoro asphalt pendi kurapwa iripo. Kana zvisina kudaro, matanho ekugadzirisa anofanira kutorwa.
Mukugadzira mitsetse, kuvakwa kwemuviri wekukanda mitsetse kunofanirwa kudururwa pachena kubva pamuswe wechoto kuenda kumusoro wechoto pazasi pechoto. Kutsigirwa kwe template kunofanira kuitwa pakati peanchor uye ndiro yesimbi. Ndiro yesimbi nechibatiso chakanyatsonamirwa nematanda emapuranga. Iyo yekutsigira formwork kureba ndeye 220mm, yakafara 620mm, kureba ndeye 4-5m, uye kona yepakati i22.5 °.
Kuvakwa kwechipiri chekukanda muviri kunofanirwa kuitwa mushure mekunge tambo yagadziriswa uye mold yabviswa. Kune rumwe rutivi, arc-shaped template inoshandiswa kuvhara kukanda kubva mumoto wemoto kusvika kumuswe wemoto. Zvimwe zvacho zvakafanana.
Kana iyo yekukanda ichizunguzika, dhaka rakasanganiswa rinofanira kuiswa muforoma yevhiri pairi kubvunda. Iyo nguva yekudengenyeka inofanirwa kudzorwa kuitira kuti pasave nemabhuru akajeka pamusoro pemuviri wekukanda. Nguva yekugadzira inofanirwa kutariswa neambient tembiricha yenzvimbo yekuvaka. Izvo zvinodikanwa kuve nechokwadi chekuti kudhirowa kunoitwa mushure mekunge iyo yekukanda yaiswa pakupedzisira uye ine rimwe simba.

5. Baking of lining
Unhu hwekubheka hwehuni hwe rotary hunokanganisa zvakananga hupenyu hwebasa rekugadzira. Muchiitiko chekubika chekare, nekuda kwekushayikwa kweruzivo rwakakura uye nzira dzakanaka, nzira yekupinza mafuta anorema ekupisa yakashandiswa mukudzika-kupisa, kwepakati-kupisa uye kupisa kwepamusoro-kupisa. Tembiricha yaive yakaoma kudzora: kana tembiricha inoda kudzorwa pasi pe150 ℃, mafuta anorema haasi nyore kupisa; kana tembiricha yakakwira kupfuura 150 ℃, kumhanya kwekupisa kunokurumidza, uye kugovera tembiricha muchoto hakuna kuenzana. Tembiricha yembambo panopiswa mafuta anorema ingangoita 350 ~ 500 ℃ yakakwirira, nepo tembiricha yezvimwe zvikamu zvakaderera. Nenzira iyi, iyo lining iri nyore kuputika (iyo yapfuura castable lining yakaputika panguva yekubika kubika), inokanganisa hupenyu hwebasa rembambo.
