cov ntaub ntawv hais txog silicon calcium manganese
Cov ntsiab lus dav dav ntawm silicon-calcium-manganese yog: silicon 40-50, calcium 12-18, manganese 12-18, phosphorus, sulfur thiab lwm yam uas tsis tuaj yeem zam tsis pub tsawg dua lossis sib npaug ntawm cov lej 0 .20; Cov Nyiaj Txiag Hlau yog qhov tsim muaj ntawm cov khoom siv silicon-calysing ntawm cov yam ntxwv muaj zog, thiab cov hlau uas tau txais zoo, thiab yog tus smelting low-alloy high-strength steel, tshwj xeeb tshaj yog rau smelting tiremeridianand steel hlau hlua thiab lwm yam khoom siv tawv tawv rau qhov zoo tshaj plaws deoxidation thiab desulfurization ntawm alloy additive, tib lub sij hawm, silicon-calcium manganese muab ib qho zoo tagnrho alloy additive rau refining ntawm txhuas-dawb deoxidized molten hlau.
Silicon-calcium-manganese tuaj yeem ib nrab kov yeej tus nqi deoxidation qeeb los ntawm deoxidation ntawm calcium-silicon alloys, thiab cov txiaj ntsig tau txais yog me me spherical inclusions uas tsis yooj yim kom tshem tawm ntawm cov hlau molten, thiab siv ntau dua hauv kev kho deoxidation. ntawm refined steel.
Lub molten steel kho los ntawm silicon-calcium-manganese tsis tsuas yog muaj fluidity zoo, tab sis kuj zoo txo cov teeb meem uas yuav tshwm sim nyob rau hauv nruam casting, xws li tsis zoo nozzle thiab txawm blockage, thiab txhim kho qhov huv si ntawm cov khoom kawg.Machinability, ductility thiab cuam tshuam lub zog.
Cov yam ntxwv ntawm silicon calcium manganese
Lub luag haujlwm tseem ceeb ntawm silicon-calcium-manganese yog deoxidizers, ua kom sov thiab inoculants. Nws yog siv rau deoxidation thiab ua kom sov hauv kev lag luam steelmaking. Silicon hauv silicon-calcium-manganese composite deoxidation, calcium muaj affinity zoo rau oxygen. Lub affinity ntawm calcium rau sulfur kuj loj heev, thiab cov khoom deoxidation thiab desulfurization yog yooj yim rau ntab thiab tshem tawm, uas txhim kho cov khoom ntawm hlau thiab txhim kho lub toughness thiab cuam tshuam ntawm hlau. Manganese tuaj yeem nce manganese cov ntsiab lus hauv cov hlau molten thiab txo cov nyiaj ntawm silicon-manganese alloys. Yog li ntawd, silicon-calcium-manganese composite deoxidizer yog ib qho zoo tagnrho deoxidizer nrog ob qho tib si deoxidation thiab manganese li hauv kev lag luam steelmaking.
Lub deoxidation ntawm molten steel yog ib feem tseem ceeb ntawm steelmaking ntau lawm. Cov pa txhuas uas muaj deoxidizers xws li hlau txhuas, Ferro-silicon, silicon, txhuas, barium, thiab lwm yam., nws cov nqi feem ntau siab dua. Txhuas muaj cov pa oxygen absorber deoxidation, thiab nws cov khoom deoxidation feem ntau suav nrog AL2O3, uas ua rau muaj kev phom sij rau cov hlau tsis zoo thiab yooj yim ua rau nodulation ntawm qhov hluav taws xob. Txhawm rau kov yeej qhov tsis txaus ntawm AL deoxidation thiab txo tus nqi ntawm deoxidizer, silicon-calcium-manganese composite deoxidizer tuaj yeem siv rau hauv cov txheej txheem smelting xws li hluav taws xob rauv --- LF furnaces thiab converters.
Thaum smelting steel, silicon-calcium-manganese muaj txiaj ntsig zoo rau kev txhim kho cov hlau zoo; Hauv smelting ntawm cov qib hlau zoo tib yam, kev siv hluavtaws deoxidizer tuaj yeem txhim kho kev huv ntawm cov hlau, thiab txo tus nqi ntawm deoxidation thiab desulfurization. Cov khoom no yog suav tias yog ib qho zoo tshaj plaws deoxidation thiab desulfurization lwm yam khoom los ntawm Hubei Hlau thiab Steel Cog, Tuam Tshoj Railway Steel Zeb, Ma Hlau thiab Hlau thiab lwm yam steel mills txhua xyoo puag ncig.
