Cov txheej txheem nodular cast iron casting yog siv cov txheej txheem nodular casting, nodular cast iron kuj tuaj yeem nyiam hlau, los ntawm cov txheej txheem xws li kev kho cua sov kom txhim kho kev ua tau zoo. Nodular cast iron hauv kev tsim cov hlau molten hauv cov txheej txheem ntawm graphite spheroid, tab sis kuj vim yog spherical graphite, yog li ntawd nodular cast iron muaj ntau yam zoo. Cov koob me me hauv qab no ntawm Furuite graphite qhia txog yuav ua li cas spherical graphite tsim:
Cov duab ntawm graphite spherical
Cov txheej txheem graphite kheej kheej muaj ob theem, thawj zaug yog graphite nucleation, hlau yaj thaum yaj ua kua, muaj ntau yam tsis yog hlau thiab qee yam tsis huv thaum ua luam dej, sib tsoo, thiab thaum kawg yuav sib sau ua ke los ua graphite pob nucleus. Tom qab graphite nucleates, ntau cov carbon atoms pib sib sau ua ke rau saum graphite core. Thaum ntau thiab ntau cov carbon atoms sib sau ua ke, lawv thaum kawg ua spherical. Qhov no yog txheej txheem thib ob ntawm graphite kheej kheej. Yog li ntawd, kom tau txais graphite kheej kheej hauv txheej txheem casting, kev tswj hwm graphite hauv txheej txheem kev loj hlob yog qhov tseem ceeb heev.
Kev tshawb fawb txog Furuite graphite pom tias spherical graphite muaj peev xwm them thiab tso tawm siab thiab electrochemical stability, yog ib qho khoom siv lithium roj teeb anode zoo tagnrho thiab ib qho khoom siv capacitor tseem ceeb, nrog rau kev ua tau zoo-rau-tus nqi piv. Tib lub sijhawm, nws muaj kev ua hluav taws xob zoo heev thiab kev ruaj ntseg tshuaj lom neeg, kev them thiab tso tawm siab, lub neej ntev, kev tiv thaiv ib puag ncig ntsuab.
