Yuav Ua Li Cas Paub Qhov Zoo Ntawm Graphite Recarburizer Rau Casting

Peb tsuas yog saib cov degree ntawm graphitization. Ib tug zoo graphite recarburizer muaj ntau tshaj {{0}}% graphite carbon. Yog tias qhov ntsuas kub ntawm qhov graphite splitter no siab tshaj 2700 degrees, cov ntsiab lus sulfur yog 0.02-0.05%, cov ntsiab lus nitrogen yog 100-200PPM, thiab tus nqi yog 7000-9000 yuan ib ton. Graphite recarburizer nrog calcination kub ntawm 2000-2700 degrees tseem hu ua semi-graphitized recarburizer, cov ntsiab lus sulfur yog 0.1-0.5, nitrogen yog 300-800ppm, thiab tus nqi yog {{13 }} yuan.

Qhov zoo ntawm graphite recarburizer rau casting yog tus yuam sij rau kev ntxiv cov hlau seem rau lub cub hluav taws xob rau melting grey hlau, thiab tus nqi txiav txim siab tias ntau lub Hoobkas siv pheej yig graphite recarburizer rau casting, tab sis qee zaum pom muaj ntau yam teeb meem zoo, nrog rau qhov tsis xws luag thaum lub sij hawm. nws siv. Rau qhov zoo tib yam grey cam khwb cia hlau, thaum cov pa roj carbon thiab silicon cov ntsiab lus siab, lub pore tsis xws luag tsis pom tseeb, tab sis nyob rau hauv high-zoo grey cam khwb cia hlau nrog tsawg carbon thiab silicon ntsiab lus, lub reflection yog pom tseeb, thiab lub pore defects nyob rau hauv lub castings yog. loj.

Rau ductile hlau castings, lub porosity defect tsis pom tseeb. Magnesium thiab tsawg ntiaj teb yuav tsum muaj cov nyhuv degassing muaj zog, tab sis cov porosity tsis xws luag kuj tshwm sim los ntawm qee lub sijhawm. Cov txiaj ntsig ntawm qib qis graphite recarburizer ntawm cov khoom siv hlau yog kwv yees feem ntau yog cov sulfur thiab lwm yam impurities uas cuam tshuam rau lub roundness ntawm graphite npas thiab cov tsos ntawm ib qho anomalous matrix. Nws zoo nkaus li tias cov nroj tsuag no tam sim no siv cov qib qis graphite recarburizer rau casting, muab tag nrho cov nqi (suav nrog cov khoom poob). Qhov no yog unprofitable tiag tiag.

Qhov taw qhia tseem ceeb rau kev sib piv qhov zoo ntawm graphitized recarburizer yog cov ntsiab lus nitrogen. Qhov sib txawv ntawm qhov zoo thiab qhov tsis zoo graphitization yog pom tseeb. Qhov kub thiab lub sij hawm ntawm calcination txiav txim siab qhov degree ntawm graphitization. Tsis tiav graphitized carburizing tshuab muaj cov ntsiab lus sulfur thiab siab nitrogen cov ntsiab lus. Ib txhia hu nws ib tug semi-graphitized recarburizer. Piv nrog rau tus nqi ntawm tag nrho graphite recarburizer, uas yog 7, 000 lossis 8, 000 yuan, tus nqi ntawm ib nrab graphite coke recarburizer yog pheej yig ntawm 3, 000 lossis 4, 000 yuan.
