Nzira yekuvaka yakakwirira alumina zvidhinha?

High-alumina zvidhinha zvidhinha zvakakamurwa kuva zvikamu zvina maererano nehukuru hwezvidhinha zvibatanidza uye dhigirii yehutano hwekushanda. Chikamu uye saizi yezvidhinha majoini zvakateerana: Ⅰ ≤0.5mm; Ⅱ ≤1mm; Ⅲ ≤2mm; Ⅳ ≤3mm. Madhaka emoto anofanira kunge akazara mumatope emajoini ezvidhinha, uye majoini ezvidhinha emukati uye kunze kwezvikamu zvepamusoro uye zvepasi zvinofanira kuzununguka.

Nheyo dzinotevera dzinofanirwa kuteedzerwa pakugadzira dhaka refractory pakukanya zvidhinha.

2.1 Usati wagadzira zvidhinha, zvakasiyana-siyana zvinofuratira slurries zvinofanirwa kufanoedzwa uye zvakafanovakwa kuti zvione nguva yekubatanidza, nguva yekutanga yekuisa, kuenderana uye kushandiswa kwemvura kwemhando dzakasiyana siyana.

2.2 Zvishandiso zvakasiyana zvinofanirwa kushandiswa kugadzira madhaka akasiyana uye kucheneswa nenguva.

2.3 Mvura yakachena inofanira kushandiswa pakugadzira madhaka akasiyana-siyana, huwandu hwemvura hunofanira kuyerwa nemazvo, uye kusanganiswa kunofanira kuva yunifomu, uye kushandiswa sezvinodiwa. Iyo hydraulic uye mhepo-inoomesa dhaka iyo yakagadzirwa haifanirwe kushandiswa nemvura, uye ivhu rakaiswa pakutanga harifanirwe kushandiswa.

2.4 Paunenge uchigadzira dhaka rakasungwa phosphate, ita shuwa nguva yakatarwa yekuteya, uye gadzirisa paunenge uchiishandisa. Madhaka akagadzirwa haafaniri kunyungudutswa nemvura pasina. Nekuda kwekuora kwayo, madhaka aya haafanire kunge akanangana negoko resimbi.

Nzvimbo yacho inofanira kunyatsoongororwa uye kucheneswa kusati kwavakwa zvidhinha.

Pamberi pekugadzira zvidhinha kuvakwa, mutsara unofanirwa kuiswa kunze, uye ukuru uye kukwirira kwechikamu chimwe nechimwe chemasoni chinofanira kuongororwa maererano nemifananidzo yekugadzira.

Izvo zvinodikanwa zvekukanya zvidhinha ndezvi: zvidhinha zvakasimba uye zvidhinha, majoini ezvidhinha akatwasuka, denderedzwa remuchinjiko, zvidhinha zvekiyi, nzvimbo yakanaka, hapana kudonhedza uye kudonhedza, uye masonry anofanirwa kuchengetwa akati sandara uye akatwasuka. Zvidhinha zvepamusoro-aluminium zvinofanirwa kuiswa mumajoini akadzika. Madhaka ari mumajoini ezvidhinha zvemasonry anofanira kunge akazara uye nzvimbo yacho inofanira kubatanidzwa.

Kurongeka kwekushandiswa kwemhando dzakasiyana-siyana dzepamusoro alumina zvidhinha inoshandiswa maererano neurongwa hwekugadzira. Paunenge uchiisa zvidhinha zvidhinha, kuzara kwedope remoto kunodiwa kusvika kupfuura 95%, uye majoini ezvidhinha epamusoro anofanira kubatanidzwa nehutu hwepakutanga, asi dhaka rakawandisa pamusoro pezvidhinha rinoputika rinofanira kubviswa nenguva.

Pakuisa zvidhinha, midziyo inochinjika senge sando dzemapuranga, sando dzerabha kana sando dzepurasitiki dzakaoma dzinofanira kushandiswa. Sando dzesimbi hadzifanirwe kushandiswa, zvidhinha hazvifanirwe kuchekwa pamadziro, uye masonry haafanirwe kurohwa kana kugadziriswa mushure mekunge madhaka akaoma.

Zvakakosha kunyatsosarudza zvidhinha. Zvidhinha zvezvinhu zvakasiyana-siyana uye marudzi akasiyana-siyana zvinofanira kuparadzaniswa zvakasimba, uye zvidhinha zvehutano hwakafanana uye rudzi zvinofanira kusarudzwa nehurefu hwakafanana.

Ukobvu hweplate yesimbi yakabatana inoshandiswa kuomesa-kuisa kazhinji 1 kusvika 1.2mm, uye inodiwa kuti ive yakati sandara, isina kutsemuka, isina kumonyoroka, uye isina maburrs. Upamhi hwe slab imwe neimwe inofanira kunge iri pasi pehupamhi hwezvidhinha ne 10mm. Iyo ndiro yesimbi haifaniri kudarika rutivi rwezvidhinha panguva yekugadzira, uye chiitiko chesimbi kurira uye bhiriji hazvizoitiki. Ndiro imwe chete yesimbi inobvumirwa mumusono wega wega. Nhete dzesimbi dzesimbi dzekugadzirisa dzinofanira kushandiswa zvishoma sezvinobvira. Kadhibhodhi inoshandiswa pakuwedzera majoini inofanira kuiswa maererano nekugadzirwa.

Paunenge uchivhara zvidhinha, zvidhinha zvakadzika zvinofanira kushandiswa kuvhara zvidhinha, uye kugadzirisa kwakanaka kunofanira kuitwa. Migwagwa yezvidhinha iri padyo inofanira kudzedzereka ne1 kusvika ku2 zvidhinha. Izvo zvinorambidzwa zvachose kukiya zvidhinha zvine castable chete, asi castables inogona kushandiswa kugadzirisa yekupedzisira kukiya zvidhinha.

Matambudziko anotevera anowanzo fanirwa kudziviswa kana uchivaka moto usingadziviriri uye kupisa-inodzivirira linings.

11.1 Dislocation: kureva, kusaenzana pakati pematanho nemabhuroko.

11.2 Oblique: Kureva kuti, haina kufuratira munzira yakachinjika.

11.3 Zvisina kuenzana grey seams: ndiko kuti, hupamhi hwegrey seams hwakasiyana, hunogona kugadziriswa nekusarudza zvidhinha zvakakodzera.

11.4 Kukwira: ndiko kuti, chiitiko chekusaenzana nguva dzose pamusoro pemadziro anotarisana, izvo zvinofanira kudzorwa mukati me1mm.

11.5 Kuparadzaniswa kubva pakati: ndiko kuti, mhete yezvidhinha haina kupindirana negoko mune arc-shaped masonry.

11.6 Kusonanidzazve: ndiko kuti, nyuchi dzepamusoro nedzepasi dzedota dzakaiswa pamusoro, uye musono mumwe chete wedota unobvumirwa pakati pezvikamu zviviri.

11.7 Kuburikidza nemusono: ndiko kuti, grey seams yemukati nekunze yakakomberedzwa yakakomberedzwa inosanganiswa, uye kunyange ganda rinoratidzwa, risingabvumirwi.

11.8 Kuzaruka: majoini edhaka muruzhowa rwakakombama madiki mukati uye makuru kunze.

11.9 Void: ndiko kuti, dhaka harina kuzara pakati pematanho, pakati pezvidhinha uye pakati pehoko, uye hazvibvumirwi mumucheka wemidziyo isingazununguki.

11.10 Majoini ane mvere: majoini ezvidhina haana kukochekera nekupusika, uye madziro haana kuchena.

11.11 Snaking: kureva, seams refu, denderedzwa seams kana horizontal seams haana kutwasuka, asi wavy.

11.12 Masonry bulge: Inokonzerwa nekushandurwa kwemidziyo, uye nzvimbo yakakodzera yemidziyo inofanirwa kukwenenzverwa panguva yekugadzira. Kana iyo kaviri-layer lining inovakwa, iyo insulation layer inogona kushandiswa kuenzanisa.

11.13 Mixed slurry: Kushandiswa kusina kunaka kweslurry hakubvumirwi.

Iyo inodzivirira moto uye inodzivirira kupisa-inopisa inosanganiswa lining yezvigadzirwa zvemasoni ichavakwa muzvikamu uye zvikamu, uye inorambidzwa zvachose kuvaka neyakasanganiswa-layer dhaka. Iyo masonry heat insulation lining inofanirawo kuzadzwa negrout. Paunosangana nemakomba uye riveting uye welding zvikamu, zvidhinha kana mahwendefa zvinofanira kugadziriswa, uye mapundu anofanira kuzadzwa nematope. Kugadzira zvisina tsarukano, kusiya maburi pese pese kana kusashandisa madhaka kunorambidzwa. Muchitsiko chekudzivirira kwekushisa, zvidhinha zvepamusoro-aluminium zvinofanira kushandiswa pakugadzira pasi pezvidhinha zve anchor, seri kwearch-foot zvidhinha, zvakapoteredza maburi uye kusangana nekuwedzera.

Majoini ekuwedzera mune yakakwirira-alumina zvidhinha lining inofanira kuiswa maererano nekugadzirwa uye haifaniri kusiiwa. Upamhi hwemajoini ekuwedzera haafanire kuve nekushivirira kwakashata, hapana marara akaoma anofanira kusiiwa mumajoini, uye majoini anofanirwa kuzadzwa nerefractory fibers kuti adzivise chiitiko chekuzara uye kusava nechinhu. Kazhinji, hapana chikonzero chekuwedzera majoini mu thermal insulation layer.

Iyo lining yezvikamu zvakakosha uye zvikamu zvine maumbirwo akaoma zvinofanirwa kunge zvakafanogadzikwa kutanga. Kune linings ane zvimiro zvakanyanya kuomarara uye yakakura kugadzirisa vhoriyamu yezvidhinha, funga kuchinja kune zvinokandwa linings.

Idzo dzakafumurwa simbi dzakasiiwa mumadziro ezvidhinha, kusanganisira bhodhi rinotsigira zvidhinha, bhodhi rekuchengeta zvidhinha, nezvimwewo, zvichanamwa nezvidhinha zvine chimiro chakasarudzika, zvinokandwa kana mafiibha anopokana, uye hazvizoratidzirwe zvakananga kune inopisa gasi panguva. use.

Anchor zvidhinha zvidhinha zvekugadzira zvemasonry, izvo zvinofanira kuchengetwa maererano nemitemo yekugadzira uye haifaniri kusiyiwa. Hapana zvidhinha zvakatsemuka zvinosungirirwa zvinofanirwa kushandiswa kutenderedza maburi anorembera. Zvikorekedzo zvesimbi zvinofanira kuiswa pasi uye kurembera zvakasimba. Makomba ekurembera uye zvikorekedzo hazvigone kubatika, gomba rakasara rinogona kuzadzwa nerefractory fiber.

Paunenge uchivaka zvidhinha zvekuvhara, zvidhinha zvakabatanidzwa uye zvidhinha zvakakombama, kana zvidhinha zvepakutanga zvisingakwanisi kuzadzisa zvinodiwa zvekuvhara, zvidhinha zvinofanira kupedzwa nechidhinha chechidhinha panzvimbo yezvidhinha zvakagadzirwa nemaoko. Ukuru hwezvidhinha zvakagadziriswa: zvidhinha zvekuvhara hazvifaniri kunge zvisingasviki 70% yezvidhinha zvepakutanga; muzvidhinha zvakabatana uye zvidhinha zvakakombama, hazvifanirwe kunge zvisingasviki 1/2 yezvidhinha zvepakutanga. Inofanira kukiyiwa nezvidhinha zvepakutanga. Nzvimbo yekushanda yezvidhinha inorambidzwa zvachose kubva pakugadzirisa. Iyo yekugadzirisa nzvimbo yezvidhinha haifaniri kutarisana nechoto, nzvimbo yekushanda kana kuwedzera.
