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