Ferrosilicontuaj yeem nce qhov kub ntawm cov hlau molten thaum lub sij hawm ua cov txheej txheem steel.
Txoj haujlwm no muaj ntau yam txiaj ntsig tseem ceeb
Txhawb kev sib cais ntawm cov ntsiab lus alloy:Qhov kub thiab txias yuav pab ua kom cov solubility ntawm cov hlau alloy (xws li chromium, npib tsib xee, thiab lwm yam), ua rau cov hlau alloy no sib npaug sib npaug hauv cov hlau molten, txhim kho kev ua haujlwm thiab zoo ntawm cov hlau alloy.
Txhim kho fluidity thiab pourability:High-temperature molten steel muaj qis viscosity thiab deg nro, uas ua rau cov hlau molten yooj yim rau ntws thiab nchuav, uas yog qhov zoo kom tau txais cov khoom zoo thiab ruaj khov.
Txo solidification shrinkage kab noj hniav thiab shrinkage porosity:Kub kub pab txo cov solidification shrinkage ntawm molten steel thaum lub sij hawm solidification txheej txheem, yog li txo qhov kev pheej hmoo ntawm shrinkage kab noj hniav thiab shrinkage porosity nyob rau hauv castings thiab txhim kho kev ncaj ncees thiab ceev ntawm castings.
Txo kev siv hluav taws xob:Rau qee qhov, nce qhov kub ntawm cov hlau molten tuaj yeem txo cov kev siv hluav taws xob rov qab thiab txuag cov nqi hluav taws xob.
Nyob rau hauv luv luv, los ntawm kev ua kom kub ntawm molten steel, solubility ntawm alloy ntsiab yuav tsum tau txhim kho thaum lub sij hawm lub steelmaking txheej txheem, lub fluidity thiab pourability ntawm molten hlau yuav optimized, qhov tshwm sim ntawm casting defects yuav txo tau, lub zog yuav txuag tau, thiab ntau lawm efficiency thiab cov khoom zoo tuaj yeem txhim kho.
