Ngā Pūrongo - Te "tino whānui" i roto i te Pereti Maitai Waro

Ko te pereti maitai waro tētahi o ngā momo rauemi maitai taketake. He rino tōna pūtake, ko te ihirangi waro kei waenga i te 0.0218%-2.11% (paerewa ahumahi), ā, kāore he nui, he iti rānei o ngā huānga whakarewa kei roto. E ai ki te ihirangi waro, ka taea te wehewehe ki:
maitai waro iti(C≤0.25%): he pakari pai, he ngāwari ki te tukatuka, nō tēnei kāwai te Q235;
maitai waro waenga(0.25%
Te maitai waro teitei(C>0.6%): tino pakeke, ā, he tino pakarukaru.

Te maitai waro Q235: te whakamāramatanga me ngā tawhā matua (paerewa GB/T 700-2006)

Te hanganga	C	Si	Mn	P	S
Ihirangi	≤0.22%	≤0.35%	≤1.4%	≤0.045%	≤0.045%

Ngā āhuatanga miihini:
Kaha whakaputa: ≥235MPa (matotoru ≤16mm)
Kaha kume: 375-500MPa
Te roa: ≥26% (te matotoru ≤16mm)

Rauemi me te Mahi

Rauemi:Ko ngā rauemi noa ko:GR.B, X42, X46, X52, X56, X60, X65, X70, me ētahi atu

Ngā Āhuatanga Mahi
Te Kaha TeiteiKa taea te tu atu i te pēhanga teitei e puta mai ana i ngā wai pēnei i te hinu me te hau māori i te wā e kawe ana.
Teitei o te PakariEhara i te mea ngāwari te pakaru ina pāngia e te pānga o waho, e ngā huringa whenua rānei, kia noho haumaru ai te mahi a te paipa.
Ātete Pai ki te WaikuraE ai ki ngā taiao whakamahinga me ngā momo pāpāho rerekē, mā te whiriwhiri i ngā rauemi me ngā tikanga maimoatanga mata e tika ana ka taea te ātete i te waikura me te whakaroa i te roa o te ora o te paipa.

Ngā Āhuatanga o te "toa hexagonal" o Q235

Mahi Tukatuka Tino Pai
Āheitanga whakarewaKāore e hiahiatia he whakamahana mua, he pai mō te whakarewa pewa, te whakarewa hau me ētahi atu tukanga (pēnei i te whakarewa hanganga maitai o te whare);
Te Āhua Matao: Ka taea te piko me te tā (hei tauira: te anga pouaka tohatoha, te paipa hau);
Te āheinga ki te mīhiniMahi pumau i raro i te tapahi tere-iti (tukatuka wāhanga mīhini).
Taurite Ā-Mīhini Whānui

Kaha vs Pakari: Ka whakaarohia e te kaha whakaputa 235MPa te ātete ki te pikaunga me te ātete pānga (ki te whakataurite ki te 195MPa o Q195);
Te Āheinga o te Maimoatanga MataHe māmā ki te whakakanapa me te rehu peita (pērā i ngā ārai, ngā kīra maitai māmā).
Te Whai Huatanga Ōhanga Tino Pai
Ko te utu he 15%-20% te iti iho i tērā o te maitai kaha-teitei iti-koranu (pērā i te Q345), e tika ana mō te tono tauine nui.
Teitei o te Paerewatanga
Matotoru noa: 3-50mm (he rawaka te taonga, he whakaiti i te huringa whakaritenga);
Ngā paerewa whakatinanatanga: GB/T 700 (ā-rohe), ASTM A36 (ōrite ā-ao).

Hokona me te Whakamahi i te "Aratohu Ārai"

Te Tāutuhi Kounga:
Āhuakāore he ngatata, he koha, he kopa (paerewa āhua pereti GB/T 709);
PūtāhuiTirohia te hanganga, ngā āhuatanga hangarau me te pūrongo kitenga hapa (me kimi hapa UT mō ngā wāhanga hanganga nui).
Rautaki ārai-waikura:
rotopeita ārai-waikura (pērā i te peita mata whero) + paninga o runga;
Waho: te whakapūmau wera-tuku (paninga ≥85μm) te paninga rehu waro-hauora rānei.
Tuhipoka Whakarewa:
Kōwhiringa tokotoko whakarewaraupapa E43 (pērā i te J422);
Pereti angiangi(≤6mm): kāore e hiahiatia he whakamahanatanga, he pereti matotoru (>20mm): whakamahanatia ki te 100-150℃ hei ārai i ngā pakaru.
