ASTM A210 Icyiciro C. (ASME SA210 Icyiciro C..
Icyiciro C gifite imiterere yubukanishi, gifite imbaraga zingana na 485 MPa nimbaraga zitanga 275. MPa.Iyi mitungo, hamwe nibigize imiti ikwiye, bituma imiyoboro ya ASTM A210 Grade C ikwiranye neza nogukoresha mubushyuhe bwinshi kandi hejuru- ibidukikije byumuvuduko kandi ushoboye guhangana ningutu ziterwa nigikorwa cyo guteka.
Imiyoboro igomba gukorwa nuburyo butagira ikidodo kandi igomba kuba ishyushye cyangwa yarangije ubukonje.
Hasi nimbonerahamwe yerekana uburyo bwo gukora imiyoboro ikonje ikonje:
None ni irihe tandukaniro riri hagati yicyuma gishyushye kandi gikonje-cyuzuye cyuma kandi udahitamo ute?
BishyushyeUmuyoboro w'icyuma udafite icyuma ni umuyoboro w'icyuma uzunguruka cyangwa ugatoborwa ku bushyuhe bwo hejuru hamwe n'ibindi bikorwa hanyuma ugakonjeshwa neza n'ubushyuhe bw'icyumba.Imiyoboro y'ibyuma muri iyi leta ubusanzwe ifite ubukana bwiza nimbaraga zimwe, ariko ubwiza bwubuso ntibushobora kuba bwiza nkimiyoboro yicyuma irangiye ikonje kuko inzira yo gutunganya ubushyuhe irashobora gutuma okiside cyangwa decarburizasi yubuso bwicyuma.
Ubukonje burangiyeUmuyoboro w'icyuma udafite icyerekezo bivuga gutunganya bwa nyuma umuyoboro wibyuma ushushanya ubukonje, kuzunguruka gukonje, nibindi bikorwa mubushyuhe bwicyumba.Umuyoboro wicyuma ukonje ufite ubukonje buhanitse, hamwe nubuziranenge bwubuso, kandi kubera ko gutunganya ubukonje bishobora kongera imbaraga nubukomezi bwumuyoboro wibyuma, imiterere yubukanishi bwumuyoboro wicyuma ukonje ukunze kuba mwiza kuruta iy'icyuma gishyushye kirangiye. .Nyamara, umubare munini wibibazo bisigaye bishobora kubyara imbere mu cyuma mugihe gikonje, bigomba gukurwaho no kuvura ubushyuhe nyuma.
Umuyoboro ushyushye wicyuma ntusaba kuvura ubushyuhe.
Imiyoboro ikonje ikonje igomba kuba subcritical annealed, yegeranye rwose, cyangwa ubushyuhe busanzwe buvurwa nyuma yubukonje bwa nyuma.

Ikizamini cya Flattening
Amosozi cyangwa kumeneka bibaho kumwanya wa 12 og 6 kumyanya yo mu cyiciro cya C gifite ubunini bwa 2.375 muri.
Ibisabwa byihariye birashobora kuboneka muriASTM A450, ingingo ya 19.
Ikizamini cyo gutwika
Ibisabwa byihariye birashobora kuboneka muri ASTM A450, ingingo ya 21.
Gukomera
Icyiciro C: 89 HRBW (Rockwell) cyangwa 179 HBW (Brinell).
Buri muyoboro wibyuma ugomba gukorerwa hydrostatike yumuvuduko cyangwa ikizamini cyamashanyarazi kidasenya.
Hydrostatike yumuvuduko wibizamini bisabwa bijyanye na ASTM 450, ingingo ya 24.
Ibisabwa bidashobora gusenya amashanyarazi bijyanye nubushakashatsi bisabwa bijyanye na ASTM 450, ingingo ya 26.
Gukora ibikorwa birakenewe kubiteke kugirango tumenye neza ko imiyoboro yujuje ibyifuzo bya sisitemu yo guteka.
Iyo byinjijwe muri boiler, tebes igomba guhagarara kwaguka no kwerekanwa iterekanye ibice cyangwa inenge.Iyo ikoreshejwe neza, imiyoboro ya superheater igomba guhagarara yose.gusudira.n'ibikorwa byo kunama bikenewe mubisabwa udatezimbere inenge.
Botop Steel nicyuma cyiza cyane cyo gusudira cyuma cya karubone ikora kandi ikanatanga ibicuruzwa biva mubushinwa, kandi ikanabika ibyuma bidafite ibyuma, biguha umuyoboro wicyuma cyiza, gisanzwe, kandi gihiganwa.
Niba ukeneye, nyamuneka twandikire, abanyamwuga, kumurongo wa serivisi yawe!
