Kuwunika kwa kugwiritsa ntchito mafuta a petroleum coke/carburizer

Carburizing wothandizira ndiye chigawo chachikulu cha kaboni, ntchito yake ndikubisa.
Pakusungunula zinthu zachitsulo ndi zitsulo, kusungunuka kwa zinthu za kaboni muchitsulo chosungunuka nthawi zambiri kumawonjezeka chifukwa cha zinthu monga nthawi yosungunula komanso nthawi yayitali yotentha, zomwe zimapangitsa kuti mpweya wa chitsulo muchitsulo sungathe kufika pamtengo woyerekeza womwe ukuyembekezeka. kuyenga.
Pofuna kupanga kuchuluka kwa mpweya wotayika posungunula chitsulo ndi chitsulo, zinthu zomwe zimakhala ndi carbon zimatchedwa carburizer.
Petroleum coking wothandizira angagwiritsidwe ntchito poponya imvi kuponyedwa chitsulo, mpweya zili zambiri 96 ~ 99%.

Pali mitundu yambiri ya zida zopangira carburizing, njira yopanga opanga ma carburizing ndi yosiyana, pali kaboni wamatabwa, kaboni wamalasha, coke, graphite, ndi zina zambiri.
Carburizer yapamwamba nthawi zambiri imatanthawuza graphitized carburizer, pansi pa kutentha kwambiri, makonzedwe a maatomu a carbon amasonyeza microscopic morphology ya graphite.
Graphitization imatha kuchepetsa zonyansa mu carburizer, kuonjezera mpweya wa carburizer ndikuchepetsa sulfure.

Pali mitundu yambiri ya carburizer, ndipo mtundu wa carburizer ndi yunifolomu.Nayi njira yosiyanitsira mtundu wa carburizer:

1. Madzi amadzi: Madzi a carburizer ayenera kukhala otsika kwambiri, ndipo madzi ayenera kukhala osachepera 1%.

2. Phulusa: Mndandanda wa phulusa la carburizer uyenera kukhala wotsika momwe ungathere.Phulusa la calcined petroleum coke carburizer ndilochepa, pafupifupi 0.5-1%.

3, volatilization: volatilization ndi gawo losagwira ntchito la carburizer, volatilization imadalira kuwerengetsa kapena kutentha kwa coke kwa carburizer ndi njira yochizira, kukonzedwa bwino kwa carburizer volatilization kuli pansi pa 0.5%.

4. Mpweya wokhazikika: Mpweya wokhazikika wa carburizer ndi gawo lothandiza kwambiri la carburizer, kukwera kwa carbon, kuli bwino.
Malinga ndi mtengo wokhazikika wa carbon index wa carburizer, carburizer imatha kugawidwa m'makalasi osiyanasiyana, monga 95%, 98.5%, 99%, ndi zina.

5. Sulfure yopezeka mu carburizer ndi chinthu chofunikira kwambiri chovulaza, ndipo mtengo wake ukakhala wotsika, umakhala wabwinoko.Sulfure zili mu carburizer zimatengera sulfure zomwe zili mu carburizer yaiwisi ndi kutentha kwa calcining.
