Kodi kusiyana pakati pa Q195, Q215, Q235, Q255 ndi Q275 ndi kotani pankhani ya zinthu?
Chitsulo chopangidwa ndi kaboni ndiye chitsulo chomwe chimagwiritsidwa ntchito kwambiri, chiwerengero chachikulu cha chitsulo chomwe nthawi zambiri chimakulungidwa kukhala chitsulo, ma profiles ndi ma profiles, nthawi zambiri sichiyenera kugwiritsidwa ntchito mwachindunji ndi kutentha, makamaka pakupanga ndi ukadaulo.
Q195, Q215, Q235, Q255 ndi Q275, ndi zina zotero, motsatana, zimasonyeza mtundu wa chitsulo, mtundu wa chitsulo ndi woimira mfundo yophukira ya chilembo (Q), mtengo wa mfundo yophukira, mtundu, khalidwe ndi zizindikiro zina (A, B, C, D) njira yochotsera okosijeni ndi zina zotero pazigawo zinayi za kapangidwe kotsatizana. Kuchokera ku kapangidwe ka mankhwala, mitundu ya chitsulo chofatsa yamitundu ... qi kutalika kwake kunali: 33, 31, 26, 24, 20 (0.5%). Chifukwa chake, popereka chitsulo kwa makasitomala, makasitomala ayenera kukumbutsidwa kugula zipangizo zosiyanasiyana zachitsulo malinga ndi zipangizo zomwe zimafunikira, kuti asakhudze ubwino wa chinthucho.
Kodi kusiyana pakati pa zinthu za Q235A ndi Q235B ndi kotani?
Q235A ndi Q235B zonse ndi chitsulo cha kaboni. Mu muyezo wa dziko lonse wa GB700-88, kusiyana kwa zinthu za Q235A ndi Q235B makamaka kumakhala mu kuchuluka kwa kaboni mu chitsulo, zinthu za Q235A zomwe zili mu kaboni mu 0.14-0.22 ﹪ pakati; Q235B sizimayesa kukhudzidwa, koma nthawi zambiri zimayesa kukhudzidwa ndi kutentha, V-notch. Poyerekeza, mawonekedwe a makina a chitsulo cha Q235B ndi abwino kwambiri kuposa chitsulo cha Q235A. Kawirikawiri, mphero yachitsulo yomwe ili mu ma profiles omalizidwa asanachoke ku fakitale imalembedwa pa mbale yozindikiritsa. Ogwiritsa ntchito amatha kudziwa ngati zinthuzo ndi Q235A, Q235B, kapena zinthu zina pa mbale yozindikiritsa.
Magiredi achitsulo aku Japan ndi SPHC, SPHD, ndi zina zotero. Kodi amatanthauza chiyani?
Chitsulo cha ku Japan (JIS series) cha chitsulo chokhazikika chimakhala ndi magawo atatu: gawo loyamba limasonyeza zinthu, monga: S (Chitsulo) amatanthauza chitsulo, F (Ferrum) amatanthauza chitsulo. Gawo lachiwiri la mawonekedwe osiyanasiyana, mitundu, ntchito, monga P (mbale) mbale, T (chubu), K (kogu) chida. Gawo lachitatu la makhalidwe a tebulo la nambala, nthawi zambiri mphamvu yocheperako yomangika. Monga: ss400 - yoyamba s kuti chitsulo (Chitsulo), yachiwiri s kuti "kapangidwe" (Structuree), 400 ya mphamvu yotsika ya chitsulo chokhazikika cha 400Mpa. Pakati pawo: sphc ---- choyamba Ssteel Steel chidule, P ya mbale Pate chidule, H ya kutentha Kutentha chidule, Kufotokozera zamalonda, zonse zimasonyeza kuti mzere wonse wotentha ndi chitsulo.
SPHD----- ikutanthauza pepala lachitsulo lotenthedwa ndi mzere wopondereza.
SPHE------- ikutanthauza mapepala achitsulo otenthedwa ndi zingwe zojambulira mozama.
SPCC------ imatanthauza pepala lachitsulo la kaboni lozungulira lozizira ndi mzere wogwiritsidwa ntchito wamba, wofanana ndi giredi ya China Q195-215A. Chilembo chachitatu C ndi chidule cha Cold, chomwe chikufunika kuti kutsimikizidwe kuti mayeso omangika kumapeto kwa giredi kuphatikiza T ya SPCCT akuchitika.
SPCD------ imasonyeza chitsulo chozizira cha kaboni ndi mzere wachitsulo chobowola, chofanana ndi chitsulo chapamwamba cha kaboni cha China 08AL (13237).
SPCE------ imasonyeza pepala lachitsulo chozizira chozungulira ndi mzere wojambulira mozama, wofanana ndi chitsulo chobowola cha China 08AL (5213). Kuti muwonetsetse kuti sichikugwira ntchito, onjezani N ku SPCEN kumapeto kwa giredi.
Chitsulo chozizira cha kaboni chopindidwa ndi chizindikiro cha mzere, chokhazikika pa A, chokhazikika pa S, 1/8 cholimba pa 8, 1/4 cholimba pa 4, 1/2 cholimba pa 2.
Khodi yomaliza pamwamba: palibe kutsirizitsa kowala kwa D, ndipo kutsirizitsa kowala kwa B. Monga SPCCT-SD imasonyeza pepala la kaboni lozizira lokhazikika, lopanda kutsirizitsa kowala kuti ligwiritsidwe ntchito nthawi zonse. Kenako SPCCT-SB imasonyeza pepala la kaboni lokhazikika, lomalizidwa bwino, lozizira lokhala ndi mphamvu zotsimikizika zamakina.
Nthawi yotumizira: Juni-24-2024
