Q345D ubushyuhe buke bwihanganira ibyuma byujuje ubuziranenge
Ibikoresho byiza byuzuye, gusudira, ubukonje nubushyuhe bwo gukora no kurwanya ruswa, hamwe nubushyuhe buke bwo hasi
Amato, amashyiga, ibikoresho byumuvuduko, ibigega byo kubikamo amavuta, ibiraro, ibikoresho bya sitasiyo, imashini zizamura nogutwara nibindi bikoresho byubatswe hamwe nuburemere bwinshi
18nb yishe ibyuma birimo Nb, bifite imitungo isa na 14MnNb, ikoreshwa cyane cyane kuri crane, blowers, imashini za chimique, nibindi
09mncupti ikirere cyangirika kwangirika kwicyuma gifite ingaruka nziza zubushyuhe bwo hasi, gusudira hamwe nubukonje nubushyuhe bukora. Ikoreshwa cyane cyane muburyo bwimashini zose ahantu h’imvura n’imvura hamwe n’ibidukikije byangiza
12mnv ibyuma byubushyuhe buke hamwe nubushyuhe bwakazi bwa - 70 ℃ bikoreshwa cyane mubice byimiterere yimashini zikonjesha zikora mubushyuhe buke
14MnNb ifite imiterere isa nicyuma cya 18nb kandi ikoreshwa cyane mubyombo nibindi bice byubatswe hamwe nubushyuhe bwakazi bwa - 20-450 ℃
16Mn ifite imiterere myiza yubukanishi, ubushyuhe buke, imikorere ya kashe ikonje, imikorere yo gusudira hamwe na mashini. Ikoreshwa cyane mubucukuzi, ubwikorezi, inganda zimiti nizindi mashini
Imiterere ya 16mnre isa nicyuma cya 16Mn, ingaruka zikomeye hamwe nubukonje bukonje buruta 16Mn, kandi intego ni kimwe nicyuma cya 16Mn
Q345D umuyoboro wibyuma nikimwe mubikoresho byumuyoboro wibyuma.
Q345D umuyoboro w'icyuma
Q345D umuyoboro w'icyuma
Q345A, Q345B, Q345C, Q345D na Q345E ni amanota meza. Ziyongera kuva kuri a kugeza kuri e, cyane cyane bitewe nubudasa bwubushyuhe bwingaruka ziterwa nibintu bitandukanye bigize mikorobe nka fosifore na sulfure, ibyo bikaba bigaragaza itandukaniro ryubushyuhe bwingaruka hamwe nubukanishi bwibikoresho bya chimique.
Q345A, nta ngaruka; Q345B, 20 ° ingaruka zubushyuhe busanzwe; Q345C, Impamyabumenyi 0; Q345D, ni - Impamyabumenyi 20; Q345E ni - Ingaruka ya dogere 40. Ku bushyuhe butandukanye bwubushyuhe, ingaruka zingaruka nazo ziratandukanye.
Q imbaraga zumusaruro ntabwo ziri munsi ya 345mp, kandi urwego rwubuziranenge rwerekana ko rurimo ibintu byanduye (karubone, manganese, silikoni, sulfure na fosifore). Nubunini bwumwanda (element) mubyuma. Nyuma yaho A, B, C na D, ntigabanye ibirimo umwanda
Q345A irimo fosifore na sulferi munsi cyangwa ihwanye na 0.045%
Q345B irimo fosifore na sulferi munsi cyangwa ihwanye na 0.040%
Q345C irimo fosifore na sulferi munsi cyangwa ihwanye na 0.035%
Q345D irimo fosifore na sulferi munsi cyangwa ihwanye na 0.030%
Q345E irimo fosifore na sulferi munsi cyangwa ihwanye na 0.025%
Uko umwanda wa fosifore na sulfure byinshi mubyuma, niko ingaruka mbi zikomeye
Q345A -
Q345B Akv ntabwo ari munsi ya 34 kuri 20 ℃
Kuri Q345C 0 ℃, Akv ntishobora kuba munsi ya 34
Q345D - Akv itari munsi ya 34 kuri 20 ℃
Kuri Q345E - 40 ℃, Akv ntabwo iri munsi ya 27
Impamvu yanyuma nuko igabanuka rya P na s mubyuma biteza imbere kunoza ubukana bwingaruka kubushyuhe buke. Imwe ni imiti ya Q345 indi ni imashini ya Q345.
