Ibyuma byo guhinga bishyushye bya 60Si2Mn, ibyuma bikomeye byo guhinga ku butaka bwumutse, ibyuma bizunguruka byo guhinga ubutaka bukomeye n'imisozi y'ubutayu, ibikoresho by'imashini z'ubuhinzi.

Ibisobanuro bigufi:

Ibyuma byo guhinga bikozwe mu cyuma kidapfa kwangirika, gifite inkombe ikoreshwa mu bushyuhe kugira ngo gikomere cyane. Bikwiriye guhinga ubutaka buto, ubutaka buto, n'ubutaka bukomeye. Imiterere yabyo yihariye imeze nk'umusenyi igabanya neza ibizinga by'ubutaka n'imizi y'ibyatsi, bigagabanya ikoreshwa ry'ibikomoka ku binyabiziga n'amavuta. Bihuye n'ibikoresho bitandukanye byo guhinga n'imashini zo guhinga, biroroshye gushyiraho kandi binoza cyane umuvuduko wo gusenya ubutaka n'imikorere myiza, bigatuma biba ibikoresho biramba byo gutunganya no gutegura ubutaka bw'ubuhinzi.

Ibisobanuro birambuye ku gicuruzwa

Ibirango by'ibicuruzwa

Iki gicuruzwa ni icyuma gikomeye cyo guhinga (kizwi kandi nk'icyuma cyo gukuraho ubutaka) cyagenewe ubuhinzi bw'ubuhinzi. Nk'igikoresho cy'ingenzi gikoreshwa n'abakora ubuhinzi n'amatarakiteri, gikoreshwa cyane cyane mu gutunganya ubutaka bw'ubuhinzi, gutunganya ubutayu, gutema ibyatsi, no gutunganya imiyoboro y'amazi. Cyagenewe by'umwihariko guhangana n'ibidukikije bigoye kandi bikomeye by'ubutaka, bigatuma kiba amahitamo meza yo kunoza imiterere y'ubutaka no kongera imikorere myiza y'ubuhinzi.

Iki gicuruzwa gikubiyemo amahame y’imiterere n’imiterere y’ubuhanga mu miterere yacyo, cyane cyane gifite imiterere isa na C n’iy’L. Urushinge ruragororotse kandi rufite ubushobozi bwo gukomera cyane. Igice cy’urushinge kigizwe n’ibice bibiri: umugozi n’umutwe w’urushinge.

Umukoki w'icyuma: Ufite imyobo ibiri ihamye yo gufatanya neza n'imashini z'ubuhinzi, bigatuma zigumana umutekano kandi ntizihinduke mu gihe cy'akazi kenshi.

Umutwe w'Intambi: Ukoresha uburyo bwo gupfunyika bumeze nk'uruziga, harimo ibyuma byo gupfunyika imbere n'ibyo gupfunyika ku mpande. Intambi yayo yihariye yo gupfunyika (hafi 119°-120°) n'uburebure bwayo bigabanya imbaraga zo guhangana n'ubutaka iyo buciwe, bigatuma ubutaka buvunika neza kandi bugakomeza gukora neza.

Kugira ngo habeho ibyifuzo byo kudakora neza no kudasaza, umubiri w'icyuma ukozwe mu byuma bikomeye nka 60Si2Mn, 60Si2MnA, na 28MnSiB.

Nyuma yo gushyushya cyane (guhindura igice cya martensitic), ubukana rusange bw'icyo gicuruzwa bugenzurwa hagati ya HRC 42 na 48, bigatuma icyuma kidacika cyangwa ngo gipfuke vuba iyo gikubiswe cyane. Byongeye kandi, amwe mu mamoderi afite agapira gashyushye gashongesha icyuma ku buso bw'icyuma, kadatuma gusa icyuma kidapfa gusa ariko kandi gafite n'akazi ko "kwikosora"—ni ukuvuga ko gakomeza ubukana bw'inkombe y'icyuma mu gihe cyo gukoresha, kagabanya ikoreshwa ry'amashanyarazi kandi kagatuma ingufu zigabanuka.

Iki gicuruzwa gikoreshwa cyane na traktori nini n'iziciriritse, kandi kibereye cyane cyane mu kuvugurura ubutaka, gutema ibyatsi bishaje, no gutera imihanda mu bibaya, mu misozi miremire no mu misozi yoroheje. Gishobora gusenya neza ubutaka butose, kongera imyenge y'ubutaka, no gutanga ahantu ho gutera imbuto hafunguye kandi hahumeka neza kugira ngo hatererwe ibihingwa nyuma yaho.
