ibisobanuro ku bicuruzwa

Amabati yicyuma muri rusange ni ijambo rusange kumpapuro zidafite ingese hamwe nimpapuro zirwanya aside. Mu ntangiriro z'iki kinyejana, iterambere ry'ibyuma bitagira umwanda ryashyizeho urufatiro rukomeye rw'ibikoresho na tekiniki mu iterambere ry'inganda zigezweho n'iterambere ry'ubumenyi n'ikoranabuhanga. Hariho ubwoko bwinshi bwibyuma bidafite ibyuma bifite ibyuma bitandukanye, kandi byagiye bigenda byiyongera mubyiciro byinshi mubikorwa byiterambere. Ukurikije imiterere y’umuryango, igabanyijemo ibyiciro bine: icyuma cya austenitike kitagira ibyuma, icyapa cya Martens kitagira ibyuma (harimo imvura igwa ibyuma bidafite ibyuma), icyuma cya ferritic, na austenite wongeyeho icyuma cya ferrite duplex.

Ibikoresho nyamukuru bigize imiti cyangwa ibintu bimwe na bimwe biranga icyuma cyashyizwe mubyuma bya chrome bitagira ibyuma, icyuma cya chrome nikel icyuma, icyuma cya chrome nikel molybdenum icyuma kidafite ibyuma na plaque nkeya ya karuboni, icyuma kinini cya molybdenum, icyuma kinini nibindi bisa. Ukurikije ibiranga imikorere no gushyira mu byiciro ibyapa, bigabanyijemo amata ya acide ya nitric irwanya ibyuma, ibyuma bya acide sulfurike irwanya ibyuma, ibyuma byerekana ibyuma bitagira umwanda, ibyuma byangirika byangirika, ibyuma bikomeye bitagira ibyuma, nibindi. .Byashyizwe mubikorwa ukurikije ibimenyetso biranga isahani yicyuma, igabanijwemo ubushyuhe buke buke bwicyuma, icyuma kitagira magnetiki icyuma, gukata kubusa ibyuma, ibyuma bya plastiki bitagira umuyonga nibindi.

Uburyo bukoreshwa muburyo bwo gutondekanya ibyiciro bushyirwa mubikorwa ukurikije imiterere yimiterere yicyuma hamwe nibigize imiti yibyuma hamwe no guhuza byombi. Mubisanzwe, igabanyijemo icyuma cya martensite, icyuma cya ferritic, icyuma cya feritike, icyuma cya austenitike kitagira ibyuma, icyuma cya duplex kitagira ibyuma hamwe n’imvura igwa icyuma kidafite ibyuma, cyangwa igabanyijemo ibyiciro bibiri: icyuma cya chrome kitagira ibyuma na nikel. Byakoreshejwe henshi Porogaramu zisanzwe: guhanahana ubushyuhe kumashini n'ibikoresho byo gukora impapuro, ibikoresho bya mashini, ibikoresho byo gusiga amarangi, ibikoresho byo gutunganya firime, imiyoboro, ibikoresho byo hanze yinyubako mu turere two ku nkombe, nibindi.

Isahani idafite ibyuma ifite ubuso bworoshye, plastike ndende, ubukana nimbaraga za mashini, kandi irwanya ruswa na acide, gaze ya alkaline, ibisubizo nibindi bitangazamakuru. Nicyuma kivanze kidashobora kubora byoroshye, ariko ntabwo kirimo ingese rwose.

Ibiranga ibicuruzwa

Kurwanya ruswa
Urupapuro rw'icyuma rudafite ingese rufite ubushobozi bwo guhangana na ruswa rusa na nichrome idahindagurika 304. Gushyushya igihe kirekire mubushyuhe bwa karubide ya chromium birashobora kugira ingaruka kuri alloy 321 na 347 mubitangazamakuru byangiza. Ahanini ikoreshwa mubushyuhe bwo hejuru, ubushyuhe bwo hejuru busaba gukangurira cyane ibikoresho kugirango wirinde kwangirika hagati yubushyuhe buke.

Kurwanya ubushyuhe bwinshi
Ibyuma bitagira umwanda bifite ubushyuhe bwo hejuru bwa okiside, ariko igipimo cya okiside kigira ingaruka kubintu bisanzwe nkibidukikije byagaragaye hamwe na morphologie yibicuruzwa.

Imiterere yumubiri
Coefficient yubushyuhe bwuzuye bwicyuma biterwa nibindi bintu, hiyongereyeho ubushyuhe bwumuriro wicyuma. Mubihe byinshi, coefficente yubushyuhe bwa firime, igipimo nicyuma cyubuso. Ibyuma bitagira umwanda bituma isuku igira isuku kandi ikagira isuku, bityo ubushyuhe bwayo bukaba bwiza kuruta ibindi byuma bifite ubushyuhe bwinshi. Liaocheng Suntory Icyuma kitagira ibyuma bitanga ibipimo bya tekiniki kumasahani yicyuma. Ibyuma bifite imbaraga nyinshi zidafite ibyuma bifite imbaraga zo kurwanya ruswa, kunama gutunganijwe hamwe no gukomera kwa site, hamwe nibikorwa byiza byo gushiraho kashe kubice byasuditswe. By'umwihariko, irimo C: 0,02% cyangwa munsi yayo, N: 0,02% cyangwa munsi yayo, Cr: 11% cyangwa irenga kandi munsi ya 17%, hamwe nibikwiye bya Si, Mn, P, S, Al, Ni, kandi bihaza 12 Mo 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 ≤ CN ≤ 0.030 icyuma kidafite ingese gishyuha kugeza 850 ~ 1250 ° C , hanyuma bigakorwa kuri 1 ° C / s Ubuvuzi bwo hejuru hejuru yo gukonjesha igipimo. Rero, irashobora kuba imiterere irimo martensite ifite agace kangana na 12% cyangwa irenga, imbaraga nyinshi za 730 MPa cyangwa zirenga, kurwanya ruswa, kunanirwa gukora, hamwe nicyuma gikomeye cyane kitagira umuyonga cyiza muri zone yibasiwe nubushyuhe. gukomera. Ukoresheje Mo, B, nibindi, ibikoresho byo gukora byamakuru byigice cyasuditswe birashobora kunozwa kuburyo budasanzwe.

Umuriro wa ogisijeni wongeyeho gaze ntishobora guca ibyuma bitagira umwanda kuko ibyuma bitagira umwanda ntabwo byoroshye okiside.
