Icyuma Q195, Q235, itandukaniro riri hagati y'ibikoresho?

Ni irihe tandukaniro riri hagati ya Q195, Q215, Q235, Q255 na Q275 mu bijyanye n'ibikoresho?

Ibyuma by’ubwubatsi bya karuboni ni byo byuma bikoreshwa cyane, umubare munini w’ibyuma bikunze kuzungurutswa mu byuma, mu buryo bw’imiterere n’imiterere, muri rusange ntibikenewe gukoreshwa mu buryo butaziguye hakoreshejwe ubushyuhe, ahanini mu buryo rusange no mu buhanga.

Q195, Q215, Q235, Q255 na Q275, n'ibindi, uko bikurikirana, bigaragaza urwego rw'icyuma, urwego rw'icyuma n'uhagarariye ingingo y'umusaruro w'inyuguti (Q), agaciro k'ingingo y'umusaruro, ubwiza, ubwiza n'ibindi bimenyetso (A, B, C, D) by'uburyo bwo gukuraho ogisijeni mu mwuka n'ibindi bice bine by'imiterere ikurikiranye. Kuva ku miterere y'imiti, urwego rworoheje rw'icyuma Q195, Q215, Q235, Q255 na Q275 runini, uko ingano ya karuboni irushaho kuba nyinshi, ingano ya manganese, niko imiterere yayo irushaho gukomera. Imiterere ya mekanike ivuye ku ngingo, ingano zavuzwe haruguru zigaragaza ko ubunini ≤ 16mm bw'ingingo y'umusaruro w'icyuma. Ingufu zayo zo gukurura zari: 315-430, 335-450, 375-500, 410-550, 490-630 (obN/mm2); qi uburebure bwayo bwari: 33, 31, 26, 24, 20 (0.5%). Kubwibyo, mugihe cyo kugeza ibyuma ku bakiriya, abakiriya bagomba kwibutswa kugura ibikoresho bitandukanye by'ibyuma hakurikijwe ibikoresho bikenewe, kugira ngo bitagira ingaruka ku bwiza bw'ibicuruzwa.

 

Ni irihe tandukaniro riri hagati y'ibikoresho bya Q235A na Q235B?

Q235A na Q235B byombi ni icyuma cya karuboni. Mu gipimo cy’igihugu cya GB700-88, itandukaniro ry’ibikoresho bya Q235A na Q235B ahanini riri mu gipimo cya karuboni mu cyuma, ibikoresho bya karuboni bya Q235A biri hagati ya 0.14-0.22 ﹪; ibikoresho bya Q235B ntibikora ikizamini cy’ingaruka, ahubwo akenshi bikora ikizamini cy’ingaruka z’ubushyuhe, V-notch. Mu buryo bunyuranye, imiterere y’icyuma cya Q235B ni myiza cyane kuruta icyuma cya Q235A. Muri rusange, uruganda rw’icyuma ruri mu miterere yarangiye mbere yo kuva mu ruganda rushyirwa ku cyapa cy’indangamuntu. Abakoresha bashobora kumenya niba ibikoresho ari Q235A, Q235B, cyangwa ibindi bikoresho biri ku cyapa cy’indangamuntu.

 

Amanota y'icyuma yo mu Buyapani ni SPHC, SPHD, n'ibindi. Bisobanura iki?

Ibyuma byo mu Buyapani (series JIS) by’ibyuma bisanzwe by’ubwubatsi ahanini bigizwe n’ibice bitatu: igice cya mbere kigaragaza ibikoresho, nka: S (Icyuma) bivuga icyuma, F (Ferrum) bivuga icyuma. Igice cya kabiri cy’imiterere itandukanye, ubwoko, ikoreshwa, nka P (isahani) iyo sahani, T (tube), K (kogu) icyo gikoresho. Igice cya gatatu cy’imibare y’imbonerahamwe, muri rusange imbaraga nke zo gukurura. Nka: ss400 - iya mbere s icyuma (Icyuma), iya kabiri s imiterere (Structuree), 400 ku mbaraga zo hasi za 400Mpa icyuma gisanzwe cy’ubwubatsi. Muri byo: sphc ---- incamake ya mbere ya Ssteel Steel, P ku isahani Pate incamake, H ku bushyuhe Incamake y’ubushyuhe, Incamake y’ubucuruzi, yose yerekana ko umurongo rusange w’icyuma ushyushye n’icyuma.

 

SPHD----- yerekana urupapuro rw'icyuma gishyushye n'umurongo wo gukandagiraho.

SPHE------ yerekana impapuro z'icyuma zishyushye n'imirongo yo gushushanya mu buryo bwimbitse.

SPCC------ yerekana urupapuro rw'icyuma cya karuboni gikonje n'umurongo wo gukoreshwa muri rusange, bingana n'urwego rw'Ubushinwa Q195-215A. Inyuguti ya gatatu C ni incamake ya Konje, isabwa kugira ngo hamenyekane neza ikizamini cyo gukurura ku mpera y'urwego hamwe na T kuri SPCCT.

SPCD------ yerekana icyuma gikonje cya karuboni n'icyuma gikoreshwa mu gukubita, bingana n'icyuma cyo mu rwego rwo hejuru cya karuboni cyo mu Bushinwa 08AL (13237).

SPCE------ yerekana urupapuro rw'icyuma cya karuboni gikonje n'umurongo wo gushushanya mu buryo bwimbitse, bingana n'icyuma cyo gukubita cya China 08AL (5213). Kugira ngo urebe ko kidakora neza, ongeramo N kuri SPCEN mu mpera y'urwego.

Urupapuro rw'icyuma cya karuboni gikonje n'imiterere yarwo, imiterere ya A, isanzwe ishyushye kuri S, 1/8 ikomeye kuri 8, 1/4 ikomeye kuri 4, 1/2 ikomeye kuri 2.

Kode yo kurangiza ubuso: nta gusoza kwa D, gusoza kwa B. Nka SPCCT-SD yerekana urupapuro rwa karuboni rukonje rukonje rukonje rukoreshwa muri rusange. Hanyuma SPCCT-SB yerekana urupapuro rwa karuboni rukonje rukonje rukonje rukonje rufite ubushobozi bwo kwemeza imikorere ya mekanike.
