The basic common sense offerrochrome:
Pakati, pasi uye micro carbonferrochromeinowanzo gadzirwa ne silicochrome alloy, chromite uye lime seyakagadzirwa.Yakanatswa uye yakasvibiswa nechoto chemagetsi che1500 ~ 6000 kV A uye inoshandiswa nepamusoro-soro yemoto slag (CaO/SiO2 ndeye 1.6 ~ 1.8) .microcarbon ferrochromeinogadzirwawo nenzira inopisa yekusanganisa pamwero mukuru.Mafuro maviri emagetsi anoshandiswa pakugadzira, imwe yekunyungudutsa silicon chrome alloy uye imwe yekunyungudutsa slag inoumbwa ne chrome ore uye lime.Kunatsa kunopatsanurwa kuita nhanho mbiri mumatangi maviri. : (1) Mushure mekunge slag kubva muchoto che slag yaiswa mutangi yekutanga, iyo silicon chromium alloy iyo yakatanga desiliconized inowedzerwa mune rimwe tangi.Nekuda kwekuwanda kwakawandisa kweoxidizing agent mu slag uye yakakwana desiliconization, micro-carbon ferrochrome ine isingasviki 0.8% silicon uye yakaderera se0.02% kabhoni inogona kuwanikwa.② Mushure meiyo slag (ine inenge 15% Cr2O3) mushure kuita mutangi rekutanga kunoendeswa kune yechipiri tangi, iyo silicon chromium alloy (ine 45% silicon) yakagadzirirwa musilicon chromium yemagetsi vira inopisa mukati me slag.Mushure mekuita, iyo silicon chromium alloy (ine 25% silicon) iyo yakatanga desilicated inowanikwa uye inowedzerwa mutangi rekutanga kuti iwedzere kupera.Iyo slag ine isingasviki 2 ~ 3% Cr2O3 inogona kuraswa.
Iyo yepakati uye yakaderera kabhoni ferrochrome inonatswa neokisijeni nzira yekufuridza.Liquid kabhoni ferrochrome inoshandiswa seyakagadzirwa zvinhu.Irimu shoma shoma uye fluorite inowedzerwa mudziva rakanyungudutswa kuita slag panguva yekuvhuvhuta, uye silicon chromium alloy kana ferrosilicate inowedzerwa isati yabviswa simbi kuti iwanezve chromium mu slag. .
Vacuum solid-state decarburization process yakakwenenzverwa, nekukuya kwakanaka kweyakakwira kabhoni ferrochrome seyakabikwa, iyo yakanaka kukuya yeyakakwira kabhoni ferrochrome, chikamu cheiyo oxidizing yekugocha seyakaokisisa uye girazi remvura kana zvimwe zvinonamira, bhora rekumanikidza, mushure mekudzika kwekushisa kuoma, mota mhando vacuum choto, iyo vacuum degree iri 0.5 ~ 10 mm hg, tembiricha ye1300 ~ 1400 ℃ kudziyisa kudzikiswa pasi pe35 ~ 50 maawa, Microcarbon ferrochrome ine isingasviki 0.03% kabhoni kana kunyange isingasviki 0.01% kabhoni inogona kuwanikwa.
Bulk verification sampling: kana batch iri pasi pematani gumi, masampuli asingasviki gumi anofanira kutorwa zvisina tsarukano kubva kuzvikamu zvakasiyana; zvikamu zvakasiyana;Apo batch iri kupfuura matani makumi matatu, masampuli asingasviki makumi matatu anofanirwa kutorwa zvisina tsarukano kubva kuzvikamu zvakasiyana.Sample imwe neimwe huremu hunofanira kunge hwakaenzana, lumpiness yayo haisi pasi pe20*20mm.Sampling amount shall not be less. kupfuura 0.03% yemujenya.Masampuli ose anotorwa anofanira kutyorwa kusvika pasi pe10mm uye akakamurwa kusvika ku1-2kg.Mushure mekusanganisa, ivo vanofanirwa kukamurwa kuita zvikamu zviviri zvakaenzana, imwe yekugadzirira sampuli uye imwe yekuchengeta.
Mumamiriro ezvinhu akajairwa, ndeyekutarisa zvirimo muchromium, zvichiteverwa nezviri mucarbon assay, chromium yemukati mumamiriro ezvinhu akajairwa inofanira kunge iri mu60% ± 0.5.
