Muaj nuj nqi ntawm Nodularizing Agent thiab Nodularizing Elements hauv Ductile Iron Production
Cov ntsiab lus qhia: Txawm hais tias muaj ntau hom nodulizers hauv tsev thiab txawv teb chaws, tsis tshua muaj magnesium alloys tam sim no siv nyob rau hauv peb lub teb chaws.Tam sim no peb tsuas yog tham txog lub luag haujlwm ntawm hom alloy no thiab nws cov ntsiab lus nodulizer.
Lub luag haujlwm ntawm spheroidizing ntsiab
Cov ntsiab lus hu ua spheroidizing hais txog cov ntsiab lus uas tuaj yeem txhawb nqa spheroidization ntawm graphite, tsim lossis nce graphite spheroids.Spheroidized cov ntsiab lus feem ntau muaj cov khoom nram qab no: (1) Muaj ib lossis ob lub valence electrons ntawm lub plhaub sab nraud ntawm lub caij, thiab 8 electrons ntawm lub plhaub thib ob.Cov qauv hluav taws xob no ua rau lub caij muaj kev sib raug zoo nrog cov sulfur, oxygen thiab carbon, uas qhia txog kev ruaj ntseg ntawm cov khoom thiab tuaj yeem txo cov sulfur thiab oxygen hauv dej.(2) Lub solubility ntawm cov ntsiab lus nyob rau hauv molten hlau yog tsawg, thiab muaj ib tug tseem ceeb nyiam sib cais thaum lub sij hawm solidification.(3) Txawm hais tias nws muaj qee qhov kev sib raug zoo nrog cov pa roj carbon, nws cov solubility hauv graphite lattice yog tsawg.Raws li cov yam ntxwv saum toj no, Mg, Ce, Y, thiab Ca yog cov khoom siv hluav taws xob zoo.
Configuration ntawm spheroidizing ntsiab thiab hom spheroidizing tus neeg sawv cev
Magnesium, lub ntiaj teb tsis tshua muaj thiab calcium tam sim no tau lees paub tias muaj peev xwm txhawb nqa graphite spheroidization, tab sis yuav ua li cas npaj thiab siv lawv ua ke nrog kev tsim khoom tiag tiag, tsis yog tsuas yog lub peev xwm spheroidizing ntawm nodulizer, tab sis kuj yooj yim npaj hauv ntau lawm, kev lag luam. raw cov ntaub ntawv, Yooj yim ntawm kev siv tau dhau los ua lub hauv paus ntsiab lus ntawm kev tsim thiab siv nodulizers.
