Ngaba uyazazi usetyenziso lweSilicon-manganese Alloy?

I-Manganese kunye ne-silicon zezona zinto zisetyenziswa kwi-carbon steel. I-Manganese yenye yezona zinto zikhupha ii-deoxidizers kwinkqubo yokwenza intsimbi. Phantse zonke iintlobo zentsimbi zifuna i-manganese ye-deoxidation. Ngenxa yokuba imveliso ye-oksijini eyenziwa xa i-manganese isetyenziselwa i-deoxidation inomlinganiselo ophantsi wokunyibilika kwaye kulula ukudada; I-manganese inokunyusa impembelelo ye-deoxidation yee-deoxidizers ezinamandla ezifana ne-silicon kunye ne-aluminium. Zonke iintsimbi zoshishino kufuneka zongeze inani elincinci le-manganese njenge-desulfurizer ukwenzela ukuba insimbi ishushu igoqwe, ifakwe kunye nezinye iinkqubo ngaphandle kokuphulwa. I-Manganese iyinto ebalulekileyo yokudibanisa kwiintlobo zentsimbi ezahlukeneyo, kwaye ngaphezu kwe-15% yongezwa kwiintsimbi ze-alloy. yemanganese ukunyusa ukomelela kolwakhiwo lwentsimbi.

Yeyona nto ibaluleke kakhulu kwintsimbi yehagu kunye nentsimbi yekhabhoni emva kwemanganese. Kwimveliso yensimbi, i-silicon isetyenziswa kakhulu njenge-deoxidizer yensimbi etyhidiweyo okanye njenge-alloy additive yokwandisa amandla ensimbi kunye nokuphucula iimpawu zayo. I-silicon iphinde ibe yindawo esebenzayo ye-graphitizing, enokuthi iguqule ikhabhoni kwintsimbi ephosiweyo ibe yikhabhoni yegrafu yasimahla. I-silicon inokongezwa kwi-iron ye-grey cast kunye ne-ductile iron ukuya kwi-4%. Inani elikhulu le-manganese kunye ne-silicon yongezwa kwintsimbi etyhidiweyo ngendlela ye-ferroalloys: i-ferromanganese, i-silicon-manganese kunye ne-ferrosilicon.

I-silicon-manganese alloy yi-alloy yensimbi eyenziwe nge-silicon, i-manganese, isinyithi, i-carbon, kunye nenani elincinci lezinye izinto. Yintsimbi yentsimbi enoluhlu olubanzi lokusetyenziswa kunye nemveliso enkulu. I-silicon kunye ne-manganese kwi-silicon-manganese alloy inobudlelwane obuqinileyo ne-oxygen, kwaye isetyenziselwa ukunyibilikisa. Iincinci ze-deoxidized eziveliswa yi-silicon-manganese alloy deoxidation kwintsimbi zikhulu, kulula ukudada, kwaye zineendawo eziphantsi zokunyibilika. Ukuba i-silicon okanye i-manganese isetyenziselwa i-deoxidation phantsi kweemeko ezifanayo, izinga lelahleko elivuthayo liya kuba liphezulu kakhulu kune-silicon-manganese alloy, kuba i-silicon-manganese alloy isetyenziselwa ukwenza insimbi. Isetyenziswa kakhulu kwishishini lentsimbi kwaye iye yaba yi-deoxidizer eyimfuneko kunye ne-alloy additive kushishino lwentsimbi. I-Silikomanganese inokusetyenziswa njenge-arhente yokunciphisa ukuveliswa kwe-ferromanganese ephantsi kwekhabhoni kunye nokuveliswa kwe-metal manganese nge-electrosilicothermal method.

Iimpawu ze-silicon-manganese alloy zihlulwe zibe yi-6517 kunye ne-6014. Umxholo we-silicon we-6517 ngu-17-19 kunye nomxholo we-manganese ngu-65-68; umxholo we-silicon we-6014 ngu-14-16 kunye nomxholo we-manganese ngu-60-63. Umxholo wabo wekhabhoni ungaphantsi kwe-2.5%. , i-phosphorus ingaphantsi kwe-0.3%, isulfure ingaphantsi kwe-0.05%.
