Khoom Description
Ferro silicon 72 feem ntau yog tsim los ntawm silicon thiab hlau nrog cov ntsiab lus siab silicon, uas ua rau nws muaj cov khoom tshwj xeeb. Ua ntej tshaj plaws, ferro silicon 72 muaj kev ua haujlwm zoo deoxidation, uas tuaj yeem tshem tawm cov pa oxygen los ntawm cov hlau molten thiab txhim kho cov hlau zoo. Tsis tas li ntawd, ferro silicon 72 muaj thermal stability thiab tshuaj lom neeg ruaj khov, thiab nws tuaj yeem tswj tau qhov kev ua haujlwm ruaj khov hauv qhov chaw ua haujlwm hnyav. Raws li cov khoom siv tseem ceeb, ferro silicon 72 yog dav siv hauv metallurgy, tshuaj lom neeg kev lag luam, tshuab thiab lwm yam lag luam.
Ferro silicon 72 plays lub luag haujlwm tseem ceeb hauv kev lag luam metallurgical. Ua ntej, ua tus deoxidizer, nws tuaj yeem tshem tawm cov pa oxygen los ntawm cov hlau molten. Oxygen yog ib qho teeb meem nyob rau hauv cov hlau, uas yuav ua rau kom lub brittleness thiab txo cov neeg kho tshuab zog ntawm hlau. Ferro silicon 72 reacts nrog oxygen nyob rau hauv molten steel los tsim oxides insoluble nyob rau hauv molten steel, thiaj li mus tshem tawm lawv los ntawm molten hlau thiab txhim kho cov zoo thiab kev ua tau zoo ntawm hlau. Tsis tas li ntawd, ferro silicon 72 tuaj yeem hnov mob nrog lwm yam impurity nyob rau hauv molten steel xws li sulfur thiab phosphorus los tsim cov tebchaw ruaj khov, yog li ntxiv purifying molten steel. Los ntawm kev ntxiv ferro silicon 72, peb tuaj yeem txhim kho qhov purity ntawm cov hlau thiab txhim kho nws cov txheej txheem thiab corrosion kuj.
Ferro silicon 72 kuj tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam foundry. Nws tuaj yeem siv los ua inoculant los txhawb lub spheroidization ntawm cam khwb cia hlau. Ductile hlau muaj cov cuab yeej zoo heev thiab kev tiv thaiv corrosion thiab nws yog dav siv hauv tsheb, tshuab thiab lwm yam. Qhov sib ntxiv ntawm ferro silicon 72 tuaj yeem txhim kho qhov spheroidization tus nqi ntawm cam khwb cia hlau thiab txhim kho nws cov microstructure thiab cov khoom. Nyob rau tib lub sijhawm, ferro silicon 72 tuaj yeem kho cov nplej ntawm cam khwb cia hlau thiab txhim kho nws qhov ntom thiab lub zog. Qhov no yuav pab tau kom txo tau qhov tsis xws luag xws li shrinkage kab noj hniav thiab cua qhov, thiab txhim kho qhov zoo thiab kev ntseeg siab ntawm castings.
