Don nemo irin wannan nau'in sikelin graphite anti-oxidation gashi, dole ne mu fara samun wasu halaye irin su juriya mai ƙarfi, ƙarancin ƙarfi, kyakkyawan aikin rigakafin lalata, ƙarfin anti-oxidation mai ƙarfi da ƙarfi mai ƙarfi. Editan mai zuwa na Furuite Graphite yana raba hanyar hana graphite oxidized a babban zafin jiki:
1. Materials da tururi matsa lamba kasa da 0.1333MPa (1650 ℃) da kuma mai kyau m Properties aka soma.
2. Zaɓi kayan aikin gilashin da ya dace da buƙatun aikin a matsayin abin rufewa da kai, kuma ya sa ya zama abin rufewa mai fashewa a cikin zafin jiki na aiki.
3. Bisa ga canjin aiki na daidaitattun makamashi na kyauta na amsawa tare da oxygen tare da zafin jiki, a zafin jiki na karfe (1650-1750 ℃), zaɓi kayan da ke da alaƙa da oxygen fiye da carbon-oxygen, kama oxygen na farko, kuma oxidize kansu don kare kariya. flake graphite. Ƙarar sabon lokaci da aka samar bayan iskar oxygen ya fi girma fiye da na farkon lokaci, wanda ke taimakawa wajen toshe tashar watsawa na ciki na oxygen kuma ya samar da shingen oxidation.
4. A aiki zafin jiki, shi zai iya sha babban adadin inclusions kamar AL2O3, SiO2, Fe2O3 a narkakkar karfe, da kuma amsa da kanta zuwa sinter, sabõda haka, daban-daban inclusions daga narkakkar karfe hankali shiga shafi.
