Kodi Mumadziwa Kugwiritsa Ntchito Silicon-manganese Alloy?

Manganese ndi silicon ndiye zinthu zazikulu zomwe zimagwiritsidwa ntchito muzitsulo za carbon. Manganese ndi imodzi mwazinthu zochotseratu zinthu zomwe zimawononga chitsulo popanga zitsulo. Pafupifupi mitundu yonse yazitsulo imafuna manganese kuti iwonongeke. Chifukwa mankhwala okosijeni opangidwa pamene manganese amagwiritsidwa ntchito pochotsa mpweya amakhala ndi malo otsika osungunuka ndipo ndi osavuta kuyandama; manganese amathanso kuonjezera mphamvu ya deoxidation ya deoxidizers amphamvu monga silicon ndi aluminiyamu. Zitsulo zonse zamafakitale zimayenera kuwonjezera pang'ono manganese ngati desulfurizer kuti chitsulo chiwotche, chopukutira ndi njira zina popanda kusweka. Manganese ndi chinthu chofunikira kwambiri cha alloying mumitundu yosiyanasiyana yazitsulo, ndipo zoposa 15% zimawonjezeredwa kuzitsulo za alloy. manganese kuti awonjezere mphamvu zamapangidwe achitsulo.

Ndilo gawo lofunikira kwambiri la alloying mu chitsulo cha nkhumba ndi chitsulo cha carbon pambuyo pa manganese. Pakupanga zitsulo, silicon imagwiritsidwa ntchito makamaka ngati deoxidizer yachitsulo chosungunuka kapena ngati chowonjezera cha aloyi kuti iwonjezere mphamvu yachitsulo ndikuwongolera zinthu zake. Silicon ndi sing'anga yabwino yojambula, yomwe imatha kusintha kaboni muchitsulo choponyedwa kukhala mpweya waulere wa graphiti. Silikoni imatha kuwonjezeredwa ku chitsulo chokhazikika cha imvi ndi chitsulo cha ductile mpaka 4%. Kuchuluka kwa manganese ndi silicon kumawonjezeredwa kuzitsulo zosungunula monga ferroalloys: ferromanganese, silicon-manganese ndi ferrosilicon.

Silicon-manganese alloy ndi aloyi wachitsulo wopangidwa ndi silicon, manganese, chitsulo, carbon, ndi pang'ono zinthu zina. Ndizitsulo zachitsulo zomwe zimagwiritsidwa ntchito mosiyanasiyana komanso zotulutsa zazikulu. Silicon ndi manganese mu silicon-manganese alloy ali ndi mgwirizano wamphamvu ndi mpweya, ndipo amagwiritsidwa ntchito posungunula. Tinthu tating'onoting'ono tomwe timapangidwa ndi silicon-manganese alloy deoxidation muzitsulo ndi zazikulu, zosavuta kuyandama, ndipo zimakhala ndi malo otsika osungunuka. Ngati silicon kapena manganese amagwiritsidwa ntchito pochotsa mpweya pansi pazikhalidwe zomwezo, kutayika kwa moto kudzakhala kwakukulu kwambiri kuposa silicon-manganese alloy, chifukwa silicon-manganese alloy imagwiritsidwa ntchito popanga zitsulo. Amagwiritsidwa ntchito kwambiri m'makampani azitsulo ndipo asanduka deoxidizer wofunikira komanso chowonjezera cha aloyi mumakampani azitsulo. Silikomanganese ingagwiritsidwenso ntchito ngati chochepetsera popanga ferromanganese ya carbon low-carbon ferromanganese ndi kupanga manganese zitsulo ndi njira ya electrosilicothermal.

Zizindikiro za alloy silicon-manganese zimagawidwa mu 6517 ndi 6014. Zomwe zili mu silicon 6517 ndi 17-19 ndi manganese 65-68; silicon zomwe zili mu 6014 ndi 14-16 ndi manganese ndi 60-63. Mpweya wawo wa carbon ndi wocheperapo 2.5%. , phosphorous ndi osachepera 0.3%, sulfure ndi zosakwana 0.05%.
