Kune akawanda marudzi ezvishandiso zvinoramba zvichishandiswa mumahovhoni ecoke, uye chimwe nechimwe chine mamiriro ayo ekushandisa uye zvinodiwa zvekuita. Aya anotevera ndiwo anowanzo shandiswa refractory zvinhu mumahovheni ecoke uye maitiro avo ekudzivirira:
1. Inowanzo shandiswa refractory zvinhu muhovheni yecoke
Silicon zvidhinha
Zvimiro: yakakwirira tembiricha kuramba (pamusoro 1650 ℃), asidhi ngura kuramba, uye zvakanaka kupisa kugadzikana.
Chishandiso: Inonyanya kushandiswa munzvimbo dzinopisa zvakanyanya senge kamuri yekupisa, carbonization chamber, uye choto chepamusoro checoke oven.
Zvekungwaririra:
Zvidhinha zveSilicon zvinowanzoita shanduko yekristaro pazasi 600 ℃, zvichikonzera shanduko yevhoriyamu, saka zvinofanirwa kudzivirirwa munzvimbo dzakaderera-tembiricha.
Panguva yekuvaka, zvidhinha zvidhinha zvinofanira kunyatsodzorwa kudzivirira kuwedzera kwezvidhinha zvidhinha pakupisa kukuru.
High-alumina zvidhinha
Zvimiro: yakakwira refractoriness (pamusoro 1750 ℃), yakanaka yekupisa kuvhundutsa kuramba, uye yakasimba corrosion kuramba.
Kushandisa: Inoshandiswa mumadziro echoto, pasi pechoto, kamuri yekuchengetedza kupisa uye zvimwe zvikamu zvehovheni yekoke.
Zvekungwaririra:
High-alumina zvidhinha zvine simba rekudzivirira kune alkaline corrosion uye inoda kudzivirira zvakananga kusangana nealkaline zvinhu.
Panguva yekuvaka, kutarisirwa kunofanira kubhadharwa pakuomeswa uye kubikwa kwemuviri wezvidhina kudzivirira kuputika.
Moto Clay zvidhinha
Zvimiro: kunaka kwekudzivirira kupisa, mutengo wakaderera, wakanaka kupisa kutyisa kuramba.
Kushandisa: inoshandiswa munzvimbo dzakaderera-kupisa senge flue yevheni yecoke uye chikamu chepasi chekamuri yekuchengetedza kupisa.
Notes:
Iyo refractoriness yezvidhinha yevhu yakaderera uye haina kukodzera nzvimbo dzepamusoro-tembiricha.
Chenjerera kune hunyoro-uchapupu kudzivirira kurasikirwa kwesimba mushure mekutora mvura.
Magnesium zvidhinha
Zvimiro: high refractoriness uye yakasimba kuramba kune alkaline erosion.
Kushandisa: inoshandiswa pasi uye muchoto checoke oven uye zvimwe zvikamu zvinosangana nealkaline zvinhu.
Notes:
Magnesium zvidhinha zviri nyore kutora mvura uye zvinoda kuchengetedzwa zvakanaka kudzivirira hunyoro.
Iyo yekupisa yekuwedzera coefficient ye magnesium zvidhinha yakakura, uye kutarisisa kunofanirwa kubhadharwa kumatambudziko ekuvhundutsa kwekupisa.
Silicon carbide zvidhinha
Zvimiro: yakakwira yekupisa conductivity, kupfeka kuramba, uye yakanakisa kupisa kutyisa kuramba.
Kushandisa: inoshandiswa mumusuwo wechoto, chivharo chevira, kupisa uye zvimwe zvikamu zvehovheni yecoke zvinoda kukurumidza kupisa kupisa.
Notes:
Silicon carbide zvidhinha zvinodhura uye zvinoda kusarudzwa zvine musoro.
Dzivisa kusangana neakasimba oxidizing magasi kudzivirira oxidation.
Refractory castables
Zvimiro: kuvakwa kuri nyore, kutendeseka kwakanaka, uye yakanakisa thermal shock resistance.
Chishandiso: Inoshandiswa kugadzirisa coke oven, yakaoma chimiro zvikamu uye yakakosha kukanda.
Notes:
Nhamba yemvura yakawedzerwa panguva yekuvaka inofanira kunyatsodzorwa kuti irege kukanganisa simba.
Kupisa kunofanirwa kusimudzwa zvishoma nezvishoma panguva yekubheka kudzivirira kutsemuka.
Refractory fiber
Zvimiro: huremu huremu, yakanaka yekudzivirira kwemafuta, uye yakanakisa kupisa kutyisa kuramba.
Kushandisa: Inoshandiswa kune insulation layer yecoke oveni kuderedza kupisa.
Notes:
Refractory fibers haidziviriri kune mechanical kukanganisa uye inoda kudzivirirwa kubva kune kunze kwekukuvara.
Shrinkage inogona kuitika pasi penguva yakareba yekupisa uye inoda kuongororwa nguva dzose.
Corundum zvidhinha
Zvimiro: yakanyanyisa kurefractoriness (pamusoro pe1800 ° C) uye yakasimba yekudzivirira kwemarara.
Kushandisa: Inoshandiswa munzvimbo dzepamusoro-tembiricha uye dzakakura-kukukurwa kwemaovheni ecoke, senge dzakatenderedza zvinopisa.
Zvekungwaririra:
Corundum zvidhinha zvinodhura uye zvinoda kusarudzwa zvine musoro.
Nyatsoteerera kune compactness yezvidhinha majoini panguva yekuvaka.
2. Kuchengetedza kwekushandiswa kwecoke oven refractory materials
Kusarudzwa kwezvinhu
Sarudza refractory zvinhu zvine musoro zvichienderana nekupisa kwezvikamu zvakasiyana zvehovheni yecoke, corrosive media (acidic kana alkaline) uye mechanical load.
Dzivisa kushandisa yakaderera-tembiricha refractory zvinhu munzvimbo yepamusoro-tembiricha kudzivirira kutadza kwezvinhu.
Kuvaka mhando
Nyatsodzora saizi yezvidhinha majoini uye shandisa yakakodzera refractory dhaka kuti uve nechokwadi chekuwanda kwemasonry.
Kune refractory castables, kuvaka kunofanirwa kuitwa zvinoenderana nereshiyo kudzivirira yakawandisa mvura yekuwedzera inokanganisa simba.
Oven kubika kushanda
Mahovhoni ecoke achangobva kuvakwa kana kugadzirwa anoda kubikwa. Tembiricha inofanira kusimudzwa zvishoma nezvishoma panguva yekubika kudzivirira kutsemuka kana kusvuura zvinhu zvinoramba nekuda kwekushanduka kwekushisa kamwe kamwe.
Kuchengetedza kwezuva nezuva
Gara uchitarisa kupfeka, kukukurwa uye kuputika kwecoke oven refractory zvinhu uye uzvigadzirise nenguva.
Dzivisa kunyanya-tembiricha kushanda kwecoke oveni kudzivirira kukuvadzwa kusati kwasvika kune zvinhu zvinoramba.
Kuchengeta uye kuchengetedza
Refractory zvinhu zvinofanira kuchengetwa munzvimbo yakaoma kudzivirira unyoro (kunyanya magnesia zvidhinha uye refractory castables).
Refractory zvinhu zvezvinhu zvakasiyana zvinofanirwa kuchengetwa zvakasiyana kudzivirira kuvhiringidzika.
Summary
Izvo zvinowanzo shandiswa zvekuramba zvidhinha mumaovheni ecoke zvinosanganisira silika zvidhinha, yakakwirira alumina zvidhinha, zvidhinha zvevhu, magnesia zvidhinha, silicon carbide zvidhinha, refractory castables, refractory fibers uye corundum zvidhinha. Paunenge uchishandisa, zvinhu zvinofanirwa kusarudzwa zvinoenderana nemamiriro chaiwo ekushanda, uye kutarisisa kunofanirwa kubhadharwa kumhando yekuvaka, kushanda kweovheni uye kugadzirisa kwezuva nezuva kuti uwedzere hupenyu hwebasa recoke oven.
