Fa'idodin Ayyukan Magnesia Carbon Bricks

Amfanin tubalin carbon magnesia sune:juriya ga yashwar slag da kyakkyawan juriya na thermal shock. A da, rashin amfanin tubalin MgO-Cr2O3 da tubalin dolomite shi ne cewa sun shafe abubuwan da suka shafi slag, wanda ke haifar da zubewar tsari, wanda ke haifar da lalacewa da wuri. Ta ƙara graphite, tubalin magnesia carbon ya kawar da wannan gazawar. Halinsa shi ne cewa slag kawai yana shiga cikin farfajiyar aiki, don haka Layer na amsawa An tsare shi zuwa saman aiki, tsarin yana da ƙarancin peeling da kuma tsawon rayuwar sabis.

Yanzu, ban da kwalta na gargajiya da bulogin magnesia carbon da aka haɗa da resin (ciki har da tubalin magnesia da aka yi da mai da aka kora),bulo-bulo na magnesia da ake sayarwa a kasuwa sun hada da:

(1) Magnesia carbon tubalin da aka yi da magnesia dauke da 96% ~ 97% MgO da graphite 94% ~ 95% C;

(2) Magnesia carbon tubalin da aka yi da magnesia dauke da 97.5% ~ 98.5% MgO da graphite 96% ~ 97% C;

(3) Magnesia carbon tubalin da aka yi da magnesia dauke da 98.5% ~ 99% MgO da 98% ~ C graphite.

Dangane da abun ciki na carbon, tubalin magnesia carbon an raba su zuwa:

(I) tubalin magnesia mai ciki da aka kora (abincin carbon da bai wuce 2%) ba;

(2) tubalin magnesia masu haɗakar da carbon (abincin carbon ƙasa da 7%);

(3) Roba resin bonded magnesia carbon tubalin (abincin carbon ne 8% ~ 20%, har zuwa 25% a cikin 'yan lokuta). Ana ƙara Antioxidants sau da yawa zuwa bulo na bulo na magnesia na bulo (abin da ke cikin carbon shine 8% zuwa 20%).

Magnesia carbon tubalin ana samar da ta hada high-tsarki MgO yashi tare da scaly graphite, carbon baki, da dai sauransu The masana'antu tsari hada da wadannan matakai: albarkatun kasa crushing, nunawa, grading, hadawa bisa ga kayan dabara zane da samfurin saitin yi, bisa ga Haɗuwa Zazzaɓin nau'in wakili yana ɗagawa zuwa kusa da 100 ~ 200 ℃, kuma ana cuɗe shi tare da ɗaure don samun abin da ake kira MgO-C laka. (Garin jiki kore). Abun laka na MgO-C ta ​​amfani da guduro na roba (mafi yawan guduro phenolic) an ƙera shi cikin yanayin sanyi; kayan laka na MgO-C da aka haɗe da kwalta (mai zafi zuwa yanayin ruwa) an ƙera su a cikin yanayin zafi (kusan 100 ° C) yana samuwa. Dangane da girman tsari da buƙatun aiki na samfuran MgO-C, kayan aikin injin girgiza, kayan gyare-gyaren gyare-gyare, ƙwanƙwasa, matsi na isostatic, matsi mai zafi, kayan dumama, da kayan aikin ramming ana iya amfani da su don aiwatar da kayan laka na MgO-C. zuwa ga manufa siffar. An sanya jikin MgO-C da aka kafa a cikin kiln a 700 ~ 1200 ° C don maganin zafi don canza wakili mai ɗaure zuwa carbon (wannan tsari ana kiransa carbonization). Don ƙara yawan tubalin magnesia carbon carbon da ƙarfafa haɗin gwiwa, ana iya amfani da filaye masu kama da masu ɗaure don zubar da tubalin.

A zamanin yau, guduro roba (musamman resin phenolic) galibi ana amfani da shi azaman mai ɗaure tubalin magnesia carbon.Yin amfani da tubalin tubalin magnesia na roba na roba yana da fa'idodi masu zuwa:

(1) Abubuwan muhalli suna ba da damar sarrafawa da samar da waɗannan samfuran;

(2) Tsarin samar da samfurori a ƙarƙashin yanayin yanayin sanyi yana adana makamashi;

(3) Ana iya sarrafa samfurin a ƙarƙashin yanayin rashin warkewa;

(4) Idan aka kwatanta da mai ɗaure kwalta, babu wani lokaci na filastik;

(5) Ƙara yawan abun ciki na carbon (ƙarin graphite ko bituminous coal) na iya inganta juriya na lalacewa da juriya.
