Lebenkii chrome ee hooseeya ee lebenka chrome ee dabka sibidhka iyo lebenkii chrome magnesia

Lebenkii chrome ee Magnesia waa badeecooyin dib -u -celin leh magnesium oxide (MgO) iyo chromium trioxide (Cr2O3) oo ah qaybaha ugu muhiimsan, iyo periclase iyo spinel oo ah qaybaha macdanta ugu weyn. Lebenka noocan ah wuxuu leeyahay dib -u -celin sare, xoog heerkulka sare, iska caabin adag oo ku wajahan nabaad -guurka alkaline, xasilloonida kuleylka ee aadka u fiican, iyo la -qabsiga qaarkood ee aagga aashitada. Alaabta ceeriin ee ugu weyn ee samaynta lebenkii magnesia-chrome waa magnesia iyo chromite. Nadiifnimada alaabta ceeriin ee magnesia waa inay ahaataa mid aad u saraysa. Shuruudaha loogu talagalay halabuurka kiimikada ee chromite waa: Cr2O3: 30 ~ 45%, CaO: ≤1.0 ~ 1.5%.

Lebenkii chrome Magnesium waxaa inta badan loo adeegsadaa warshadaha biraha, sida dhisidda dusha sare ee foornada dabka, dhalooyinka foornada korontada, foornooyinka wax lagu nadiifiyo ee ka baxsan foornada iyo foorno kala duwan oo biraha aan dhalaalayn ah. Qaybta heerkulka sare ee derbiga foornada ee foornada korontada ee aadka u sarraysa waxay ka samaysan tahay leben ka samaysan fusnesia-chrome, aagga nabaad-guurka sare ee foornada sifeynta ee ka baxsan foornada waxaa laga sameeyay walxo macmal ah, aag-nabaad-guurka sare ee foornada dhalaalaysa biraha aan birta ahayn wuxuu ka samaysan yahay leben la isku qurxiyey oo magnesia-chrome ah iyo walxo macmal ah. Ka samaysan lebenkii chrome magnesia. Intaa waxaa dheer, lebenkii magnesia-chrome ayaa sidoo kale loo adeegsadaa aagga gubanaya ee shumacyada rotary sibidhka iyo dib-u-soo-saarayaasha dhalooyinka.

Astaamaha jirka iyo kiimikada ee lebenkii chrome ee hooseeya ee lebenka chrome iyo lebenkii chrome magnesia chrome ee tooska ugu xirnaa ee loo isticmaalay dabka sibidhka waa sida soo socota:

La xidhiidha halabuurka iyo wax -qabadka labadan nooc ee lebenkii, warshadaha iyo qodobbada kala duwan waa in fiiro gaar ah loo yeesho ku dhaqanka adeegsiga shooladda sibidhka.

1. Dahaarka lebenka

Si toos ah loogu daro lebenyada magnesia-chrome ee ka hooseeya 1500, isbeddelka xariiqa ayaa gaari kara +0.2% -0.8%. Waxaa ku jira taarikada birta ah ama dhoobada dib -u -ceshada wareegga lebenka si ay u nuugaan qalabkan wadajirka ah ee la ballaariyay, sidaa darteed habka nadiifinta nadiifka ah ee aan lahayn taargada birta ama dhoobada dabka lama isticmaali karo. , Iyo lebenkii chromium -ka ee magnesia chrome waxaa la siiyaa barkin kartoon, kan dambe oo dhumucdiisuna tahay 2mm

2. Weelka dubista

Lebenkii magnesia-chrome ee sida tooska ah ugu xidhan waxay aad ugu nugul yihiin culayska gudaha ee dahaarka lebenka ee ay keento kululaynta iyo qalooca jidhka dabka, sidaas darteed waxaa loo baahan yahay in si adag loo xakameeyo.
Lebenkii magnesia-chrome ee sida tooska ah ugu xirnaa waxaa ku jira chromium aad u badan, waxay leeyihiin iska caabin hooseysa daxalka alkali ee jawiga oksaydhka, iyo xidhmooyinka isku xidhka ee wejiga chromium-ka ku jira ayaa burburay. Lebenku waa wax sahlan in waxyeello loo geysto oo deegaanka u horseeda wasakh halis ah.

3. U adkaysiga yareynta jawiga

Falcelin isku mid ah ayaa ka dhacda labada nooc ee lebenka jawiga yaraynaya, taas oo burburisa wejiga isku xidhka aakhirkana keenta burbur ku yimaada lebenkii. Isku xidhka tooska ah ee lebenka magnesia-chrome ayaa si aad ah u saamayn doona.

4. Saameyn ku yeelashada samayska maqaarka kilyaha

Lakab hodan ku ah C4AF ayaa la abuuri doonaa inta u dhexeysa karammium-ka hooseeya iyo dahaarka lebenka ee magnesia-chrome iyo clinker-ka, sidaa darteed wax-qabadka maqaarka kilyaha ayaa ka fiican. Waxqabadka maqaarka dabka si toos ah loogu daray lebenka magnesia-chrome way ku kala duwan yihiin halabuurka lebenka. Mar haddii maqaarka diirku caadi yahay Marka samayska iyo dayactirku fiicnaadaan, heerkulka dusha lebenka hoostiisa ee maqaarku aad buu hoos ugu dhacaa, aadna muhiim uma aha in si toos ah laysugu daro faa’iidooyinka xoogga kuleylka sare ee lebenka chrome magnesia.
Hadda wuxuu soo baxay leben yar oo chrome magnesia-chrome ah, leben khaas ah oo aan chrome lahayn, awoodda wax-soo-saarka ilaa 6000-10000T / h ee mashiinka PC-ga, heerkulka sare iyo iska-caabbinta naxdinta kuleylka ayaa aad muhiim u ah, waxay soo saareen caaro u dhiganta Spar oo ay weheliso daahirsanaanta sare ee aan lahayn chromium-magnesium gaar ah ayaa inta badan loo adeegsadaa aagga kala-guurka ee kilyaha sibidhka.
