Recarburizerpopanga zitsulo zokhala ndi recarburizer (zopangira zitsulo zachitsulo za People's Republic of China, YB/T 192-2001 zitsulo zopangidwa ndi recarburizer) ndi chitsulo choponyedwa ndi recarburizer, ndi zinthu zina zowonjezera zimathandizanso pakubwezeretsanso, monga ma brake pad okhala ndi zowonjezera, monga friction materials.Recarburizer ndi yakunja zitsulo, ironmaking recarburizer yaiwisi.High quality recarburizer ndi chowonjezera chothandizira pakupanga zitsulo zapamwamba kwambiri.

Kugwiritsa ntchito carbon agent:

Mu smelting ndondomeko, chifukwa batching zosayenera kapena kulipiritsa ndi mochulukira decarburization ndi zifukwa zina, nthawi zina chifukwa zitsulo mpweya okhutira sanali kukwaniritsa zofunika za nthawi pachimake, ndiye kwa madzi zitsulo carburization.Kawiri ntchito carburizing wothandizila carburizing nkhumba chitsulo, elekitirodi. ufa, petroleum coke powder, makala ufa ndi coke powder.Converter smelting medium and high carbon steel, kugwiritsa ntchito mafuta a petroleum coke okhala ndi zonyansa zochepa monga carburizing agent.Zofunika za recarburizer pa top blown converter steelmaking ndi carbon yokhazikika, yotsika phulusa. , volatiles, sulfure, phosphorous, nayitrogeni ndi zonyansa zina, zouma, zoyera, ndi zolimbitsa tinthu tating'onoting'ono.

Gulu lokhazikika la kaboni limagawidwa kukhala:

w(C)>96%, zinthu zosakhazikika ≤1.0%, W (S)≤0.5%, W (chinyezi)≤0.55%, kukula kwa tinthu 1 mpaka 5mm.

Ngati tinthu kukula bwino kwambiri, n'zosavuta kuwotcha.Ngati ndi coarse kwambiri, imayandama pamwamba pa chitsulo chosungunula ndipo sichapafupi kutengeka ndi chitsulo chosungunula.Pa kukula kwa tinthu tating'onoting'ono ta ng'anjo mu 0.2-6mm, chitsulo ndi kukula kwachitsulo chakuda mu 1.4-9.5mm , mkulu mpweya zitsulo kumafuna otsika nayitrogeni, tinthu kukula 0.5-5mm, ndi zina zofunika zenizeni malinga ndi ng'anjo smelting workpiece mtundu ndi zina zotero tsatanetsatane wa chiweruzo yeniyeni ndi kusankha.

1, njira yolowera m'ng'anjo:

Recarburizer ndi yoyenera kusungunuka mu ng'anjo yolowera, koma kugwiritsa ntchito kwake sikufanana malinga ndi zofunikira za ndondomekoyi.

(1) kugwiritsa ntchito recarburizer mu sing'anga pafupipafupi ng'anjo yamagetsi yosungunula, malinga ndi chiŵerengero kapena zofunikira zofanana ndi mpweya ndi zinthu zomwe zimawonjezeredwa kumunsi kwa ng'anjo yamagetsi, kuchira kumatha kufika kupitirira 95%;

(2) ngati kusowa kwa mpweya kusintha, khumi ndi awiri ukonde ng'anjo slag, kuphatikiza carburant, ndi kukweza kutentha kwa chitsulo chosungunula, kapena yokumba alekitiramu woyambitsa kupasuka mpweya mayamwidwe, mlingo kuchira ndi mozungulira 90%, ngati otsika kutentha. carbonization ndondomeko, kusungunula ng'anjo kutentha gawo chabe la madzi chitsulo chosungunuka pansi pa kutentha otsika, onse recarburizer kamodzi mu chitsulo chamadzimadzi, Pa nthawi yomweyo, ndi kukanikizidwa mu chitsulo chosungunula ndi mlandu olimba kuti asachite. kuvumbulutsa pamwamba pa chitsulo chosungunuka.Mwa njira iyi, carburization ya chitsulo chamadzimadzi imatha kufika kupitirira 1.0%.

2, kunja kwa ng'anjo carburizing:

(1) kupopera ufa wa graphite m’thumba

Pogwiritsa ntchito ufa wa graphite ngati recarburizer, voliyumu ya jekeseni ndi 40kg / t, ndipo mpweya wa chitsulo chamadzimadzi ukuyembekezeka kuwonjezeka kuchoka pa 2% mpaka 3%. 1299 ℃ . ndi CO kuchepetsa mpweya kuti apititse patsogolo mphamvu ya carburization.

(2) kugwiritsa ntchito recarburizer pamene chitsulo

100-300 zolinga za graphite ufa carburizer akhoza kuikidwa mu thumba, kapena ku thanki chitsulo ndi otaya mu, pambuyo madzi chitsulo mokwanira anawitsidwa, mmene ndingathere kupasuka mayamwidwe mpweya, mlingo kuchira mpweya ndi za 50% .

Amagwiritsidwa ntchito poponya, chitsulo choponyedwa, chitsulo chosungunula, choponyedwa chidzakhala ndi chofunikira pa carbon, carburant monga momwe dzina lake limatanthawuzira ndikuwonjezera mpweya wa carbon mu chitsulo chamadzimadzi, ndipo, mwachitsanzo, amagwiritsidwa ntchito posungunula ng'anjo yamoto kwa chitsulo cha nkhumba, zidutswa. chitsulo, kubwerera ku ng'anjo yamoto, chitsulo cha carbon chili chokwera, koma mtengo wogula zinthu zowonongeka ndi wokwera kwambiri, kotero onjezani zotsalira, kuchepetsa kuchuluka kwa chitsulo choponyedwa, Kuwonjezera kwa recarburizer kungachepetse mtengo woponyera pamlingo wina.
