Kuongororwa kwekushandiswa kwepetroleum coke / carburizer

Mukuita kunyungudutsa kwesimbi uye zvigadzirwa zvesimbi, kunyunguduka kwekabhoni element musimbi yakanyungudutswa kunowanzo wedzera nekuda kwezvinhu zvakaita sekunyungudusa nguva uye nguva yakareba yekupisa, zvichikonzera kuti iyo kabhoni yemukati musimbi yakanyungudutswa haikwanise kusvika kune iyo theoretical kukosha inotarisirwa. kunatsa.

Kuti ugadzire huwandu hwekabhoni yakarasika mukunyungudutsa kwesimbi nesimbi, zvinhu zvine kabhoni zvakawedzerwa zvinonzi carburizer.
Petroleum coking agent inogona kushandiswa mukukanda grey cast iron, iyo kabhoni yemukati inowanzo 96 ~ 99%.

Kune akawanda marudzi ecarburizing agent zviwanikwa, carburizing agent vagadziri maitiro ekugadzira zvakare akasiyana, kune huni kabhoni, marasha kabhoni, coke, graphite, nezvimwe.
Yemhando yepamusoro carburizer kazhinji inoreva iyo graphitized carburizer, pasi pemamiriro ekushisa kwepamusoro, kurongeka kwekabhoni maatomu anoratidza microscopic morphology yegraphite.
Graphitization inogona kuderedza zvirimo zvetsvina mucarburizer, kuwedzera kabhoni yecarburizer uye kuderedza iyo sulfur yemukati.

Kune akawanda marudzi e carburizer, uye iyo mhando index ye carburizer yunifomu. Iyi inotevera ndiyo nzira yekusiyanisa kunaka kwe carburizer:

1. Mvura yemvura: Mvura ye carburizer inofanira kunge yakaderera sezvinobvira, uye mvura inofanira kuva isingasviki 1%.

2. Ash content: Ash index ye carburizer inofanira kunge yakaderera sezvinobvira. Iyo madota emukati ye calcined petroleum coke carburizer yakadzikira, ingangoita 0.5 ~ 1%.

3, volatilization: volatilization ndiyo isingashande chikamu checarburizer, volatilization inoenderana necalcination kana coke tembiricha yecarburizer uye maitiro ekurapa, yakanyatsogadziriswa carburizer volatilization iri pazasi 0.5%.

4. Fixed carbon: Iyo yakagadziriswa kabhoni yecarburizer ndiyo inonyanya kubatsira chikamu checarburizer, iyo yakakwirira iyo carbon value, zviri nani.
Zvinoenderana neyakagadziriswa kabhoni index kukosha kweiyo carburizer, iyo carburizer inogona kukamurwa kuita mamakisi akasiyana, senge 95%, 98.5%, 99%, nezvimwe.

5. Sulfur content: Sulfur content ye carburizer chinhu chakakosha chinokuvadza, uye kuderedza kukosha, zviri nani. Iyo sulfur yemukati me carburizer zvinoenderana neiyo sulfur yemukati ye carburizer mbishi zvinhu uye calcining tembiricha.
