Rau cam khwb cia hlau los yog foundry kev lag luam ntawm hluav taws xob rauv smelting, kev siv uas tsis muaj leej faj, tsis muaj nitrogen, siab nqus tus nqi carburizer yog lub hauv paus ntawm carburizing tshuab.
Graphitized petroleum coke recarburizer yog cov chaw tsim khoom tseem ceeb ntawm Liaoning, Tianjin, Shandong thiab lwm yam.
Liaohe oilfield yog thaj chaw tsim cov roj av uas tsis muaj leej faj nyob hauv lub ntiaj teb, thiab cov roj av graphitized coke muaj cov sulfur thiab nitrogen tsawg tshaj plaws.
Lub porosity ntawm recarburizer kuj tseem ua lub luag haujlwm tseem ceeb hauv cov nyhuv ntawm recarburizer thiab qhov nqus ntawm recarburizer.
Los ntawm cov txheej txheem tsim khoom, lub qhov hws ntawm cov roj coke recarburizer tau qhib tag nrho, kom qhov chaw tshwj xeeb ntawm cov recarburizer tau ua kom tiav, cov khoom muaj super permeability, tuaj yeem yaj sai sai hauv cov hlau molten, thiaj li ua kom qhov nqus tau zoo tshaj plaws thiab carburizing efficiency.
Raws li kev siv sib txawv ntawm cov khoom siv recarburizer, cov khoom siv sib txawv, muaj ntau yam khoom siv raw thiab cov txheej txheem ntau lawm, xws li ntoo carbon, coal carbon, coke, graphite, thiab lwm yam, uas muaj ntau yam me me, ntau yam.
Tus neeg saib xyuas zoo carburizing feem ntau yog hais txog graphitization carburizing tus neeg saib xyuas.
Kev npaj ntawm carbon atoms ntawm qhov kub thiab txias yog teem rau hauv daim ntawv microscopic graphite, yog li nws yog hu ua graphitization.
Graphitization tuaj yeem txo cov ntsiab lus ntawm impurities hauv carburizing tus neeg sawv cev, nce cov ntsiab lus carbon ntawm carburizing tus neeg sawv cev, txo cov ntsiab lus ntawm cov sulfur.
Kev siv cov carburizing cov neeg ua haujlwm hauv castings tuaj yeem ua rau kom cov khoom seem, txo cov npua hlau los yog tsis siv npua hlau.
Nyob rau hauv lub cub hluav taws xob smelting ntawm txoj kev pub mis, yuav tsum koom nrog carburizer thiab seem steel thiab lwm yam khoom xyaw, thiab tuaj yeem xaiv cov tshuaj me me ntxiv rau saum npoo ntawm cov hlau molten, tab sis yuav tsum tsis txhob muaj ntau cov khoom noj rau hauv cov hlau molten, txhawm rau tiv thaiv ntau dhau. oxidation, carbon ntsiab lus ntawm castings, casting carbon ntsiab lus tsis pom tseeb, raws li qhov piv ntawm lwm yam raw khoom thiab cov ntsiab lus carbon los txiav txim tus nqi ntawm recarburizer.
Ntau hom cam khwb cia hlau, raws li qhov yuav tsum tau xaiv ntau hom recarburizer.
Cov yam ntxwv ntawm recarburizer nws tus kheej yog qhov kev xaiv ntawm cov ntaub ntawv ntshiab graphitized uas muaj cov pa roj carbon monoxide, txhawm rau txo cov impurities ntau dhau ntawm npua hlau, qhov kev xaiv tsim nyog ntawm recarburizer tuaj yeem txo cov nqi ntawm cov castings.
Carburizing tus neeg sawv cev yog tsim rau induction rauv smelting, tab sis nws cov kev siv tshwj xeeb sib txawv raws li kev xav tau.
Tus neeg sawv cev carburizing siv nyob rau hauv nruab nrab zaus hluav taws xob rauv smelting tuaj yeem muab ntxiv rau nruab nrab thiab qis ntawm lub cub hluav taws xob raws li qhov sib piv lossis cov pa roj carbon sib npaug, thiab tus nqi rov qab tuaj yeem ncav cuag ntau dua 95%.
Yog tias cov pa roj carbon ntau tsis txaus los kho cov ntsiab lus carbon, thawj zaug ntxuav cov slag hauv qhov cub, thiab tom qab ntawd ntxiv cov carburizer, los ntawm cov cua sov molten hlau, electromagnetic stirring los yog dag nplawm kom yaj thiab nqus cov pa, qhov rov qab tuaj yeem ncav cuag li 90. %.
Yog tias siv cov txheej txheem recarburizer qis, uas yog, tus nqi tsuas yog melts ib feem ntawm cov hlau molten, thiab cov hlau molten kub tsawg, tag nrho cov recarburizer yuav muab ntxiv rau cov hlau molten tib lub sij hawm, thaum cov khoom them nqi yuav yuav tsum nias rau hauv lub molten hlau, tiv thaiv nws raug rau saum npoo ntawm molten hlau.
Los ntawm txoj kev no, carburization ntawm molten hlau tuaj yeem ncav cuag ntau dua 1.0%.
Petroleum coke recarburizer tuaj yeem siv rau casting grey cam khwb cia hlau.
Cov muaj pes tsawg leeg feem ntau yog carbon: 96-99%;
S0.3-0.7%.
Feem ntau siv hauv steelmaking, grey cam khwb cia hlau, nres ncoo, cored hlau, thiab lwm yam.
Henan Liugong Graphite Co., Ltd., calcined petroleum coke recarburizer graphitization recarburizer chaw tsim tshuaj paus, los qhia koj calcined petroleum coke yog calcined roj av coke recarburizer, lub hom phiaj yog tsuas yog tshem tawm impurities, thiab calcined roj av coke recarburizer graphit recarburizer graphitization rau hauv sulfurization. , dej thiab volatients.
