Icyuma Q195, Q235, itandukaniro ryibikoresho?

Ni irihe tandukaniro riri hagati ya Q195, Q215, Q235, Q255 na Q275 ukurikije ibikoresho?

Ibyuma byubaka Carbone nicyuma gikoreshwa cyane, umubare munini ukunze kuzunguruka mubyuma, imyirondoro hamwe numwirondoro, mubisanzwe ntabwo ukeneye gukoreshwa nubushyuhe butaziguye, cyane cyane mubikorwa rusange nubuhanga.

Q195, Q215, Q. , B, C, D) uburyo bwa deoxygeneation yibimenyetso nibindi bice bine bigize urutonde. Uhereye ku bigize imiti, ibyiciro byoroheje byoroheje Q195, Q215, Q235, Q255 na Q275 amanota manini, uko karuboni nyinshi, ibirimo manganese, niko plastike ihagaze neza. Ibikoresho bya mashini uhereye kumanota, amanota yavuzwe haruguru yerekana ko ubunini ≤ 16mm yumusaruro wibyuma. Imbaraga zacyo zikomeye ni: 315-430, 335-450, 375-500, 410-550, 490-630 (obN / mm2); qi kurambura kwayo byari: 33, 31, 26, 24, 20 (0.5%). Kubwibyo, mugihe cyo kumenyekanisha ibyuma kubakiriya, abakiriya bagomba kwibutswa kugura ibikoresho bitandukanye byibyuma ukurikije ibikoresho bisabwa, kugirango bitagira ingaruka kumiterere yibicuruzwa.

 

Ni irihe tandukaniro riri hagati ya Q235A na Q235B?

Q235A na Q235B byombi ni ibyuma bya karubone. Mubipimo ngenderwaho byigihugu GB700-88, Q235A na Q235B gutandukanya ibintu biri mubintu bya karuboni yibyuma, ibikoresho bya Q235A yibikoresho bya karubone muri 0.14-0.22 ﹪ hagati; Q235B ibikoresho ntabwo ikora ikizamini cyingaruka, ariko akenshi ikora ikizamini cyingaruka zubushyuhe, V-notch. Ugereranije, imiterere yubukorikori bwibikoresho Q235B nibyiza cyane kuruta ibyuma Q235A. Muri rusange, uruganda rukora ibyuma mumwirondoro yarangiye mbere yo kuva muruganda rushyirwa ku cyapa kibaranga. Abakoresha barashobora kumenya niba ibikoresho ari Q235A, Q235B, cyangwa ibindi bikoresho kuri plaque.

 

Ibyiciro by'ibyuma byabayapani ni SPHC, SPHD, nibindi.

Ibyuma byabayapani (JIS series) amanota yicyuma gisanzwe cyubatswe ahanini kigizwe nibice bitatu: igice cya mbere cyerekana ibikoresho, nka: S (Icyuma) bisobanura ibyuma, F (Ferrum) bisobanura icyuma. Igice cya kabiri cyimiterere itandukanye, ubwoko, ikoresha, nka P (isahani) isahani, T (tube), K (kogu) icyo gikoresho. Igice cya gatatu cyimbonerahamwe iranga umubare, muri rusange imbaraga ntoya. Nka: ss400 - s yambere icyuma (Ssteel), icya kabiri s "imiterere" (Imiterere), 400 kumurongo wo hasi wa 400Mpa ibyuma bisanzwe byubatswe. Muri byo: sphc ---- icyambere cya Ssteel Steel, P kubisahani Pate ahinnye, H kubushuhe Ubushuhe Ubushuhe, Amagambo ahinnye yubucuruzi, byose byerekana ko muri rusange umurongo ushyushye hamwe nicyuma.

 

SPHD ----- yerekana urupapuro rushyushye ruzengurutse urupapuro hamwe na kashe yo gushiraho kashe.

SPHE ------ isobanura impapuro zishyushye zishyushye hamwe nimirongo yo gushushanya byimbitse.

SPCC ------ isobanura impapuro zikonje za karubone zikonje hamwe nimirongo ikoreshwa muri rusange, bihwanye nu Bushinwa Q195-215A. Inyuguti ya gatatu C ni impfunyapfunyo ya Cold, isabwa kugirango ikizamini cya tensile kirangire amanota wongeyeho T kuri SPCCT.

SPCD ------ yerekana ibyuma bikonje bya karuboni bikonje hamwe nicyuma cyo gukubita, bihwanye nu Bushinwa 08AL (13237) ibyuma byujuje ubuziranenge bwa karubone.

SPCE ------ yerekana impapuro zikonje za karubone zikonje kandi zishushanya gushushanya cyane, bihwanye n'Ubushinwa 08AL (5213) gukubita ibyuma. Kugirango udakora, ongera N kuri SPCEN urangije amanota.

Ubukonje bukonje bwa karubone urupapuro no kwerekana izina, imiterere ya A, isanzwe ihindagurika kuri S, 1/8 igoye kuri 8, 1/4 gikomeye kuri 4, 1/2 gikomeye kuri 2.

Kurangiza kode yubuso: nta gloss irangiza kuri D, gloss irangiza kuri B. Nka SPCCT-SD yerekana ubushyuhe busanzwe, nta gloss irangiza imbeho ikonje ya karubone kugirango ikoreshwe muri rusange. Noneho SPCCT-SB yerekana ubushyuhe busanzwe, bwarangiye neza, ubukonje buzengurutse urupapuro rwa karubone hamwe nibikoresho byemewe.
