Daim ntawv thov: spheroidizing hlau / inoculation hlau / spheroidizing cored hlau / casting steelmaking.
Cov txheej txheem ntim: kab rov tav thiab ntsug, lub cable tuaj yeem muab faib ua kais sab hauv thiab sab nraud.
Khoom Description
Calcium silicon cored hlau muaj cov calcium silicon alloy core thiab cov hlau sab nraud. Cov txheej txheem tseem ceeb yog calcium silicon alloy hmoov, uas yog cov hmoov nplej uas muaj cov khoom siv silicon thiab calcium thiab muaj cov deoxidation zoo thiab desulfurization zog. Lub plhaub sab nrauv yog ua los ntawm cov hlau los yog lwm yam khoom siv hlau los qhwv thiab tiv thaiv cov core alloy hmoov. Calcium silicon cored hlau feem ntau muaj cov qauv linear, nrog rau ntau qhov chaw thaiv kev tsim los ntawm cov ntaub ntawv hlau txheej txheem nyob rau ntawm qhov ntev ntawm lub cev hlau. Cov ntu thaiv no yog ua los ntawm cov hmoov hlau uas tsis muaj dej noo thiab tsis muaj kuab paug rau cov hlau, thiab siv los tiv thaiv cov tub ntxhais hlau cov hmoov tsis txhob ntub thiab paug thaum khaws cia thiab kev thauj mus los. Nyob rau tib lub sijhawm, cov qauv kev tiv thaiv tsis tu ncua yog muab rau sab nrauv ntawm lub plhaub kom muaj kev sib txhuam ntawm cov khoom noj khoom haus thiab cov tawv nqaij ntawm cored hlau, kom ntseeg tau tias cov hlau cored tuaj yeem ua tau zoo rau hauv cov hlau molten. lub crystallizer.
Lub ntsiab kev lag luam siv calcium silicon cored hlau yog concentrated nyob rau hauv lub tshav pob ntawm steel smelting. Cov khoom siv silicon thiab calcium hauv calcium silicon cored hlau yog cov deoxidizers zoo. Nyob rau hauv cov txheej txheem steelmaking, calcium silicon cored hlau tuaj yeem hnov mob sai sai nrog oxygen hauv cov hlau molten los tsim silicon oxide thiab calcium oxide, yog li txo cov pa oxygen hauv cov hlau molten thiab txhim kho cov purity thiab zoo ntawm cov hlau. Cov ntsiab lus calcium hauv calcium silicon cored hlau muaj cov nyhuv desulfurization. Calcium reacts nrog sulfur los tsim calcium sulfide, uas muaj ib tug tsawg melting point thiab yog ib qho yooj yim mus tshem tawm los ntawm molten steel, li no txo cov sulfur ntsiab lus nyob rau hauv molten steel. Sulfur yog ib qho teeb meem hauv cov hlau uas yuav txo tau cov khoom siv dag zog thiab corrosion tsis kam ntawm hlau. Yog li ntawd, cov nyhuv desulfurization ntawm calcium silicon cored hlau yog qhov tseem ceeb rau kev txhim kho cov hlau zoo. Qhov sib ntxiv ntawm calcium silicon cored hlau tuaj yeem hloov pauv morphology thiab kev faib tawm ntawm kev suav nrog hauv cov hlau. Los ntawm kev tswj cov nyiaj thiab lub sij hawm ntxiv ntawm calcium silicon cored hlau, cov inclusions nyob rau hauv steel yuav ua tau me me thiab dispersed, yog li txhim kho cov neeg kho tshuab zog thiab kev ua tau zoo ntawm steel.
Cov khoom silicon nyob rau hauv calcium silicon cored hlau pab txhim kho lub fluidity ntawm cov hlau molten. Thaum lub sij hawm nruam casting txheej txheem, zoo molten steel fluidity pab kom txo tau qhov tsis xws luag nyob rau hauv lub ingot thiab txhim kho qhov zoo ntawm lub ingot. Cov ntsiab lus calcium nyob rau hauv calcium silicon cored hlau kuj tseem pab txo qis kev tsim cov kab nrib pleb hauv cov ingot. Cov ntsiab lus calcium tuaj yeem hnov mob nrog oxygen, sulfur thiab lwm yam hauv cov hlau molten los tsim cov ntsiab lus qis-melting. Cov tebchaw no tuaj yeem ua lub luag haujlwm lubricating thaum lub sij hawm solidification txheej txheem ntawm lub ingot, txo cov kev ntxhov siab nyob rau hauv lub ingot, thiab yog li txo qhov tshwm sim ntawm cov kab nrib pleb.
