Lub tshuab ua hlau muaj xws li cov tshuab sintering, coking thiab moj tej tawg rauv thiab lawv cov khoom siv ntxiv. Qhov kev faib ua feem ntawm cov ntaub ntawv hauv ob sab phlu maj mam hloov los ntawm cov khoom zoo li mus rau unshaped refractories linings tau maj mam nce nyob rau hauv xyoo tas los no.
Txoj siv sintering tshuab ignition rauv sivrefractory plasticsthiab high-aluminiumrefractory castables, thiab tseem tuaj yeem ua rau hauv prefabricated qhov chaw nrog phosphate refractory castables rau hoisting siv. Siv cov corundum castables rau cov khoom siv hluav taws xob thiab sab saum toj ntawm lub qhov cub, thiab siv cov khoom siv insulating castables los yog refractory fibers li linings rau qhov chaw ntawm lub cub tawg nrog kev ua haujlwm zoo.
1. Kev puas tsuaj rau lub qhov cub tuaj yeem kho nrog cov tshuaj tsuag
Lub tshav kub rwb thaiv tsev txheej thiab npog txheej ntawm lub coke cub ru tsev yog cam khwb cia on-site nrog refractory castables. Thaum lub taub hau cub tawg puas lawm, nws tuaj yeem kho nrog cov tshuaj tsuag. Tsis tas li ntawd, cov khoom siv coke qhuav quenching kuj siv hnyav lossis lub teeb refractory castables. Lub qhov rooj rauv tau hloov los ntawm hnyav castables mus rau semi-heavy castables. Vim hais tias lub qhov rooj cub tawg nquag qhib, hnyav castables hnyav dhau thiab tsis tsim nyog rau kev siv ntawm qhov chaw, hloov mus rau semi-heavy castables txo qhov hnyav thiab tseem ua tiav cov nyhuv thermal rwb thaiv tsev.
2. Cov khoom siv refractory tsis zoo li cas yog siv?
Lub qhov cub tawg yog ua los ntawm prefabricated blocks ua los ntawm qis-cement thiab high-aluminium castables rau hoisting thiab masonry siv. Nws tuaj yeem tsim los ntawm cov khoom siv cob-bonded aluminium-carbon unburned cib. Cov phab ntsa dej txias ntawm cov qhov cub tawg loj yog tsim los ntawm silicon carbide castables. Lub qhov cub hauv qab cushion thiab cov pob qij txha nyob ib puag ncig yog ua los ntawm cov cement castables qis thiab silicon carbide fillers. Thaum lub qhov cub hauv ob sab phlu puas lawm, refractory pressed av nkos thiab refractory spray xim yog siv los kho nws. Lub filling nruab nrab ntawm lub cub tawg hearth thiab lub cub tawg phab ntsa yog ntim nrog dej tsis muaj av nkos thiab yog txhaj nyob rau hauv ob kauj ruam. Nyob rau hauv xyoo tas los no, kuj tseem muaj cov tshuaj tsuag txheej ncaj qha nrog silica sol, uas tuaj yeem txau ncaj qha thiab siv los ua cov ntaub. Qhov no yog ib tug tshiab technology. Txawm tias tsis muaj ntau manufacturers siv nws, cov nyhuv yog zoo heev.
Blast furnace tapholes feem ntau yog thaiv nrog bulk anhydrous av nplaum kom ruaj khov tapping thiab du qhib ntawm lub taphole. Lub qhov cub tawg kais dej trench yog tsim los ntawm cov hlau taw tes castables, lub ntsiab trench castables, qis cement castables rau thawj txheej, lwm qhov chaw yog tsim los ntawm tus kheej-flowing refractory castables thiab tsis-ci castables, thiab cov seem trench yog tsim nrog tsis muaj ci. ramming cov ntaub ntawv. Ramming kev tsim kho.
3. Qhov nruab nrab thiab me me kub moj tej tawg qhov cub hauv ob sab phlu unshaped refractories
Nyob rau hauv xyoo tas los no, me me thiab nruab nrab-qhov loj me me kub moj tej tawg rauv linings thiab kub moj tej tawg qhov cub burners tau tsim nrog prefabricated blocks ntawm refractory castables los yog cam khwb cia rau ntawm qhov chaw. Lub dome kuj tseem tuaj yeem raug cam khwb cia nrog corundum castables los ua ib txoj hauv kev ua haujlwm. Ntxiv mus, kev kho kuj tseem tuaj yeem nqa tawm sab nraum lub qhov cub hluav taws xob nrog corundum castable.
Lub cub tawg lub cev ntawm lub cub tawg kub loj yog kab nrog lub plhaub ntawm lub cub tawg. Koj tuaj yeem pleev xim pleev xim nrog 1.0 Bicarbonate. Lub dome kuj tseem tuaj yeem txau nrog txheej txheej ntawm cov kua qaub-resistant tshuaj pleev xim los ua ib qho hauv ob sab phlu los tiv thaiv kev nkag mus thiab yaig ntawm lub plhaub ntawm lub tshuab hluav taws xob los ntawm sulfur-muaj flue gas.
Tsis tas li ntawd, lub tshuab hluav taws xob kub kub tawg ib puag ncig thiab cov kav dej, cov kav dej cua, cov cua kub cua kub thiab lwm qhov chaw tsis tau ua ntej ua ntej nrog ntau hom khoom siv pob zeb liab hauv xyoo tas los no. Kev tsim khoom yog teeb meem, thiab kev tsim kho yog teeb meem ntau dua. Refractory castables ntxiv nrog andalusite yog siv. Tag nrho cov nyhuv pouring kuj zoo heev. Ntxiv mus, thaum lub sij hawm kho thaum muaj xwm ceev, kub patching tuaj yeem ua ncaj qha yam tsis muaj ncua sij hawm tsim kho. Lub torpedo tso tsheb hlau luam thiab hlau sib tov rauv yog ib feem los yog tag nrho ua los ntawm castables, thiab refractory sprays yog siv los kho.
