Ingabe Uyazi Ukusetshenziswa Kwe-Silicon-manganese Alloy?

I-Manganese ne-silicon yizakhi eziyinhloko ze-alloying ezisetshenziswa ku-carbon steel. I-Manganese ingenye yama-deoxidizers ayinhloko enqubweni yokwenza insimbi. Cishe zonke izinhlobo zensimbi zidinga i-manganese ukuze i-deoxidation. Ngoba umkhiqizo we-oksijini okhiqizwa lapho i-manganese isetshenziselwa i-deoxidation inephuzu eliphansi lokuncibilika futhi kulula ukuntanta; i-manganese ingaphinda ikhulise umphumela we-deoxidation wama-deoxidizer aqinile njenge-silicon ne-aluminium. Zonke izinsimbi zezimboni zidinga ukwengeza inani elincane le-manganese njenge-desulfurizer ukuze insimbi ikwazi ukushisa igoqelwe, i-forge nezinye izinqubo ngaphandle kokuphuka. I-Manganese iyisici esibalulekile sokuhlanganiswa kwensimbi ezinhlotsheni zensimbi ezihlukahlukene, futhi ngaphezu kuka-15% yengezwa ezinsimbi ze-alloy. we-manganese ukwandisa amandla esakhiwo sensimbi.

Kuyinto ebaluleke kakhulu i-alloying element ku-pig iron kanye ne-carbon steel ngemva kwe-manganese. Ekukhiqizeni insimbi, i-silicon isetshenziswa kakhulu njenge-deoxidizer yensimbi encibilikisiwe noma njengesengezo se-alloy ukwandisa amandla ensimbi futhi ithuthukise izakhiwo zayo. I-silicon iphinde ibe i-graphitizing medium esebenzayo, engaguqula ikhabhoni kunsimbi ephonswe ibe yikhabhoni ye-graphite yamahhala. I-silicon ingezwa ensimbi evamile empunga kanye ne-ductile iron ifike ku-4%. Inani elikhulu le-manganese ne-silicon yengezwa ensimbi encibilikisiwe ngendlela ye-ferroalloys: i-ferromanganese, i-silicon-manganese ne-ferrosilicon.

I-Silicon-manganese alloy iyingxube yensimbi eyakhiwe nge-silicon, manganese, iron, carbon, kanye nenani elincane lezinye izakhi. Kuyingxube yensimbi enezinhlobonhlobo zokusetshenziswa kanye nokukhipha okukhulu. I-silicon ne-manganese ku-silicon-manganese alloy anobudlelwane obuqinile nomoya-mpilo, futhi asetshenziselwa ukuncibilikisa. Izinhlayiya ezine-deoxidized ezikhiqizwa i-silicon-manganese alloy deoxidation ensimbi zinkulu, zintanta kalula, futhi zinamaphuzu aphansi ancibilikayo. Uma i-silicon noma i-manganese isetshenziselwa i-deoxidation ngaphansi kwezimo ezifanayo, izinga lokulahlekelwa okuvuthayo lizoba phezulu kakhulu kune-silicon-manganese alloy, ngoba i-silicon-manganese alloy isetshenziswa ekwenzeni insimbi. Isetshenziswa kabanzi embonini yensimbi futhi isiphenduke i-deoxidizer ebaluleke kakhulu kanye nesengezo se-alloy embonini yensimbi. I-Silikomanganese ingasetshenziswa futhi njenge-ejenti yokunciphisa ukukhiqizwa kwe-ferromanganese ephansi-carbon kanye nokukhiqizwa kwe-metallic manganese ngendlela ye-electrosilicothermal.

Izinkomba ze-silicon-manganese alloy zihlukaniswe zibe ngu-6517 no-6014. Okuqukethwe kwe-silicon ye-6517 yi-17-19 kanye nokuqukethwe kwe-manganese ngu-65-68; okuqukethwe kwe-silicon ka-6014 kungu-14-16 kanti okuqukethwe kwe-manganese kungu-60-63. Okuqukethwe kwawo kwekhabhoni kungaphansi kuka-2.5%. , i-phosphorus ingaphansi kuka-0.3%, isulfure ingaphansi kuka-0.05%.
