Recarburizer: CPC Calcined Petroleum Coke ya Cast Iron

Kufotokozera Kwachidule:

Calcined Petroleum Coke ndi chinthu chofunikira kwambiri popanga aluminiyamu. Imapangidwa poika petroleum coke yaiwisi "yobiriwira" yapamwamba kwambiri m'ma uvuni ozungulira, komwe imatenthedwa kutentha kwa madigiri 1200 mpaka 1350 C (2192 mpaka 2460 F). Kutentha kwakukulu kumachotsa chinyezi chochulukirapo, kuchotsa ma hydrocarbon onse otsala ndikusintha kapangidwe ka kristalo ka coke, zomwe zimapangitsa kuti ikhale yolimba kwambiri pamagetsi. Mu maola ochepa, calcined petroleum coke imaziziritsidwa kuyambira madigiri 1350 C mpaka madigiri 200 C, pomwe imatha kusungidwa bwino ndikusamutsidwa kupita kumalo osungiramo zinthu kapena kuyikidwa mwachindunji m'mabotolo otumizira, magalimoto akuluakulu, magalimoto a sitima, mabwato kapena zombo.

Coke ya petroleum yokhala ndi calcium ili ndi kapangidwe kofanana ndi siponji komwe kamagwira ntchito yofunika kwambiri popanga ma anode. Ma pores ake amalola zinthu zomangira kuti zilowe mkati mwa tinthu ta coke ndikupanga chipika cholimba cha carbon, chomwe opanga aluminiyamu amayendetsa magetsi m'miphika yawo yosungunulira. Pakapita nthawi, ma anode amamwetsedwa, pafupifupi matani 40 a coke ya petroleum yokhala ndi calcium pa matani 100 aliwonse a aluminiyamu opangidwa. Pakadali pano, palibe cholowa m'malo mwa calcium petroleum coke popanga ndi kugwiritsa ntchito ma anode a aluminiyamu osungunulira.
