Ferro silicon (FeSi), ib qho tseem ceeb ferroalloy muaj xws li hlau thiab silicon, ua ib yam khoom tseem ceeb nyob rau hauv ntau yam kev lag luam, nrog steelmaking thiab casting sawv raws li nws cov thawj daim ntawv thov teb. Nws cov tshuaj muaj pes tsawg leeg ncaj qha dictates nws lub cev thiab cov khoom siv tshuaj, yog li cuam tshuam nws qhov tsim nyog rau ntau hom kev lag luam.
Core Chemical Composition ntawm Ferro Silicon
1.1 Cov ntsiab lus tseem ceeb
Raws li cov hlau alloy (Fe) thiab silicon (Si), ferro silicon cov ntsiab lus silicon yog qhov tseem ceeb tshaj plaws ntawm nws qib thiab kev ua haujlwm. Cov ntsiab lus silicon feem ntau yog li ntawm 15% mus rau 90%, nrog rau kev hloov pauv raws li cov kev xav tau tshwj xeeb. Hlau, raws li lub hauv paus ntsiab lus, tso nyiaj rau feem ntau ntawm cov seem muaj pes tsawg leeg, ua kom cov hlau ruaj khov thiab sib haum nrog lwm cov ntaub ntawv metallurgical.
1.2 Cov ntsiab lus taug qab
Ntxiv rau cov hlau thiab silicon, ferro silicon feem ntau muaj cov kab me me, suav nrog txhuas (Al), calcium (Ca), carbon (C), phosphorus (P), thiab sulfur (S). Cov ntsiab lus no, txawm hais tias tam sim no nyob rau hauv qhov tsawg kawg nkaus, ua rau muaj kev cuam tshuam tseem ceeb ntawm kev ua haujlwm ntawm alloy:
Aluminium & Calcium:
Txhim khu lub peev xwm deoxidizing thiab desulfurizing ntawm ferro silicon. Nyob rau hauv steelmaking, lawv pab tshem tawm pliaj oxygen thiab sulfur los ntawm molten steel, txhim kho cov hlau purity, mechanical zog, thiab corrosion kuj.
Cov pa roj carbon:
Nws cov ntsiab lus yog tswj nruj me ntsis, vim tias cov pa roj carbon ntau dhau tuaj yeem cuam tshuam rau qhov zoo ntawm cov khoom qis -carbon lossis ultra- qis- carbon steel khoom.
Phosphorus & Sulfur:
Feem ntau suav hais tias yog teeb meem impurities. Lawv cov concentration yog txwv rau qib qis (feem ntau qis dua 0.05% rau txhua tus) hauv siab - zoo ferro silicon, vim tias lawv tuaj yeem txo cov ductility thiab toughness ntawm hlau yog tias muaj ntau dhau.
1.3 Cov khoom tseem ceeb sib raug zoo nrog kev sib xyaw
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm ferro silicon ncaj qha tsim nws cov khoom tseem ceeb, nrog rau cov ntsiab lus silicon yog qhov tseem ceeb tshaj plaws:
Melting Point:
Cov ntsiab lus silicon siab dua sib raug rau qhov qis dua. Piv txwv li, 75% ferro silicon muaj qhov qis qis dua li 45% ferro silicon, ua kom nws yaj sai sai thiab sib xyaw nrog cov hlau molten thaum lub sij hawm steelmaking, yog li txhim kho kev tsim khoom.
Deoxidizing / Desulfurizing Peev Xwm:
Kev sib xyaw ua ke ntawm silicon, aluminium, thiab calcium txiav txim siab qhov peev xwm no. Cov qib nrog cov ntsiab lus nruab nrab mus rau siab silicon (piv txwv li, 72% thiab 75%) ua ke nrog cov kab ke tsim nyog yog nyiam rau deoxidation thiab desulfurization hauv steel ntau lawm.
Hom Ferro Silicon Qib & Lawv daim ntawv thov
