phosphorus hlau FeP16
Thaum lub sij hawm tsim cov hlau, ferric phosphorus yog tsim los ntawm cov khoom lag luam. Nws yog skimmed tawm sab saum toj ntawm slag thaum lub sij hawm tus npua hlau conversion txheej txheem. Cov txheej txheem ntawm Bessemer, tseem hu ua Thomas txheej txheem, yog ib qho ntawm thawj txheej txheem los ua qhov kev hloov pauv no. Yog tias xav tau, cov hlau tuaj yeem ua kom nkig ntau dua los ntawm kev khaws cov nqi sib txawv ntawm ferrophosphorus hauv cov txheej txheem.
Ferrophosphorus yog cov hlau alloy uas muaj hlau thiab phosphorus. Cov ntsiab lus phosphorus txiav txim siab qhov zoo ntawm cov khoom, xws li ntawm 23% mus rau 32%.
Ferrophosphorusyog ib qho khoom los ntawm cov txheej txheem steelmaking thiab yog qhov tshwm sim ntawm kev hloov pauv ntawm npua hlau, uas tau muab tshem tawm los ntawm sab uas tuaj rau hauv kev sib cuag nrog cov slag tsim nyob rau hauv cov txheej txheem. Nws kuj tseem muaj nyob hauv cov khoom lag luam hauv phosphorus.
Kev siv hlau phosphorus tsis yog ib qho tsis ntev los no. Hloov chaw, nws tau siv los ua cov khoom sib xyaw hauv cov hmoov metallurgy txij li xyoo 1939. Sintered steel yog alloyed nrog phosphorus hlau, es tsis yog unalloyed sintered steel, kom muaj zog. Raws li kev tsim kho tshiab ntawm cov hlau phosphorus hmoov, sintered steel tuaj yeem muaj qhov zoo ductility thiab siab zog.
Cov hlau tshiab nrog cov khoom zoo tuaj yeem tsim los ntawm kev ntxiv ferrophosphorus rau cov hlau alloys. Thaum hlau phosphorus ntxiv rau cov hlau, nws tiv thaiv cov hlau los ntawm oxidizing thiab xeb.
Kev siv Ferrophosphate:
Qhov kev sib xyaw ntawm hlau thiab phosphorus no muaj ntau yam kev siv, xws li:
Kev tsim cov phosphorus castings
Ferrophosphate yog siv nyob rau hauv kev tsim cov high-strength low-alloy tshwj xeeb steels (HSLA)
Ferrophosphorus tuaj yeem siv ua deoxidizer hauv hlau
Hlau phosphorus yog siv los ua cov khoom siv desiccant.
Ferrophosphorus ua ib feem ntawm high-strength low-alloy steel
Ferrophosphorus ua raws li lub cev qhuav dej kom tshem tawm cov dej thaum tsim cov hlau
