Gịnị bụferrochrome?
Ferrochrome (FeCr) bụ ihe alloy nke chromium na ígwè nwere n'etiti 50% na 70% chromium. Ihe karịrị 80% nke ụwa ferrochrome ka etinyere n'ọrụ na mmepụta nke igwe anaghị agba nchara.Dabere na ọdịnaya carbon, enwere ike kewaa ya na: Hnke carbon ferrochrome/HCFeCr (C: 4% -8%),chrome carbon ferro dị ọkara/MCFeCr(C:1%-4%),
Ferrochrome carbon dị ala/LCFeCr (C: 0.25% -0.5%),Micro carbon ferrochrome/MCFeCr:(C:0.03-0.15%).
Kedu uru ferrochrome dị?
1. Ferro chromenwere uru nke ịba ụba nguzogide oxidation ígwè na usoro nke nchara.
N'ime usoro nchara n'ime ferrochrome nwere ike ịbawanye nguzogide oxidation nke ígwè nke ọma, ihe chromium dị na ferrochrome nwere ike chebe ígwè ahụ nke ọma, nke mere na ọnụ ọgụgụ oxidation ya na-ebelata iji mee ka nkwụsị oxidation nke ígwè dịkwuo mma, nwere uru nke imeziwanye ọrụ ahụ. ndu Ízurẹlu;
2, Ịgbakwunye nha ferrochrome n'ime nchara a wụrụ awụ nwere uru nke ịkwalite nguzogide corrosion nke ígwè nke ọma.
N'ime usoro nchara, ịgbakwụnye ụfọdụ ferrochrome dịka ọdịnaya nke ihe dị na nchara a wụrụ awụ nwere ike imeziwanye nguzogide corrosion nke ígwè.Ihe chromium dị na ferrochrome nwere ike ijikọ nke ọma n'elu igwe iji nye mkpuchi mkpuchi, si otú ahụ nwee uru nke nguzogide corrosion.
3. Ferrochrome nwere uru nke na-emeziwanye ike nke ọma ma na-eyi nguzogide ígwè
Ugbu a, a na-etinyekarị usoro nchara na ferrochrome, isi ihe kpatara ya bụ n'ihi na ferrochrome nwere ike imeziwanye ike nke ọma ma na-eyi nguzogide ígwè, ihe chromium na ferrochrome adịghị mfe ijikọta ya na oxygen, ya mere ọ nwere ike imeziwanye ikike nke ígwè oxidation nke ọma. nguzogide, na mgbakwunye, ferrochrome nwekwara ike mee ka ihe ndị na-adịghị ọcha nchara dị ọcha iji melite ike nke ígwè.
Ngwa nke ferrochrome
① Ejiri na mmepụta nke igwe anaghị agba nchara ， Igwe anaghị agba nchara na-adabere na chromium maka ọdịdị ya na iguzogide corrosion.
② Dị ka ihe mgbakwunye alloy bụ isi na nchara
③ Dị ka oké mkpa mgbakwunye na usoro nke ala carbon ígwè agbaze
