Farantin Bakin Karfe Mai zafi
Ana buƙatar ya iya jure wa lalata oxalic acid, sulfuric acid iron sulfate, nitric acid, nitric acid hydrofluoric acid, sulfuric acid jan karfe sulfate, phosphoric acid, formic acid, acetic acid da sauran acid.Ana amfani da shi sosai a masana'antar sinadarai, abinci, magunguna, yin takarda, man fetur, makamashin atomic da sauran masana'antu, da kuma sassa daban-daban na gine-gine, kayan dafa abinci, kayan tebur, motoci da kayan aikin gida.Don tabbatar da cewa kayan aikin injiniya irin su ƙarfin samar da ƙarfi, ƙarfin ƙarfi, haɓakawa da taurin nau'ikan faranti na bakin ƙarfe daban-daban sun dace da buƙatun, faranti na ƙarfe dole ne a sha magani mai zafi kamar annealing, maganin maganin da kuma tsufa kafin bayarwa.
Bakin karfe farantin yana da santsi surface, high plasticity, tauri da inji ƙarfi, kuma shi ne resistant zuwa lalata acid, alkaline gas, bayani da sauran kafofin watsa labarai.Wani nau'in karfe ne wanda ba shi da sauƙin tsatsa, amma ba shi da cikakkiyar tsatsa.
Lalacewar juriya na bakin karfe ya dogara ne akan abun da ke ciki na gami (chromium, nickel, titanium, silicon, aluminum, da dai sauransu) da tsarin ciki.Chromium yana taka muhimmiyar rawa.Chromium yana da kwanciyar hankali na sinadarai, yana iya samar da fim mai wucewa akan saman karfe, ware karfe daga waje, kare farantin karfe daga hadawan abu da iskar shaka kuma yana haɓaka juriya na farantin karfe.Bayan an lalata fim ɗin wucewa, juriya na lalata yana raguwa.
Dangane da hanyar masana'anta, akwai nau'ikan mirgina mai zafi da sanyi mai sanyi, gami da farantin bakin ciki mai kauri na 0.5-4 mm da kauri farantin da kauri na 4.5-35 mm.
Dangane da halaye na tsarin ƙarfe na ƙarfe, ana iya raba shi zuwa nau'ikan 5: nau'in austenite, nau'in nau'in ferrite, nau'in ferrite, nau'in martensite da nau'in hazo.
High ƙarfi bakin karfe farantin da kyau kwarai lalata juriya, lankwasawa processability da taurin waldi sassa, kazalika da stamping processability na waldi sassa da masana'antu Hanyar.Musamman, bakin karfen da ke dauke da Si, Mn, P, s, Al da Ni tare da abun ciki mai dacewa kasa da 0.02% na C, kasa da 0.02% na N, fiye da 11% na Cr da kasa da 17%, da kuma saduwa da bukatun 12 ≤ Cr Mo 1.5si ≤ 17, 1 ≤ Ni 30 (cn) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3mo ≥ 16.0, 0.006 ≤ C n.0 zuwa 5 ≤ ~ 1250 ℃, sa'an nan kuma zafi magani za a za'ayi a wani sanyaya kudi fiye da 1 ℃ / s.Ta wannan hanya, zai iya zama babban ƙarfin bakin karfe farantin karfe tare da abun ciki na martensite fiye da 12% ta ƙarar, babban ƙarfin fiye da 730mpa, juriya na lalata da lankwasawa, da kyakkyawan ƙarfi na walƙiya zafi yankin da ya shafa.Ana iya inganta aikin hatimi na sassa masu waldadi ta hanyar sake amfani da Mo, B, da sauransu.
