Kia mōhio ki te rauemi

Ngā Whakarōpūtanga Rauemi Noa

Ngā tono matua i te mākete Ko te kani matao e aro ana ki te mākete pereti whakarewa.

E toru ngā wāhanga matua o ngā pereti whakarewa:

Whakarōpūtanga mā te rauemi:

1. ngā rauemi whakapaipai whakarewa rino
2. ngā rauemi whakapaipai konganuku kore-ferrous
3. ngā rauemi whakapaipai whakarewa motuhake

Pango Kongakonga

Ko ngā rauemi whakarewa rino e whakamahia ana i roto i te hangarau ko te rino maka me te maitai, he koranu i hangaia mai i te rino me te waro hei huānga matua.

He aha ngā rauemi ka taea te tapahi e ngā hua kani matao?

Te nuinga e whakamahia ana mō ngā rauemi maitai waro-waenga, waro-tiketike me te waro-iti

Ko te maitai waro e pā ana ki ngā koranu rino-waro he iti iho i te 2.11% te ihirangi waro.

E ai ki te nui o te waro, ka taea te wehewehe kia:

He rino waro iti (0.1~0.25%)

Te maitai waro waenga (0.25~0.6%)

Te maitai waro teitei (0.6~1.7%)

1. Rino Ngāwari

E mōhiotia ana ko te maitai ngawari, he maitai waro iti, kei waenganui i te 0.10% ki te 0.25% te nui o te waro, ā, he ngāwari ki te tango i ngā momo tukatuka pērā i te hanga, te whakarewa me te tapahi. He maha ngā wā ka whakamahia hei hanga mekameka, rivet, pūtu, toki, me ētahi atu.

Ngā momo maitai ngawari

Rino koki, rino hongere, kurupae-I, paipa rino, rīpene rino, pereti rino rānei.

Te tūranga o te maitai waro iti

Whakamahia hei hanga i ngā momo wāhanga hanga whare, ipu, pouaka, oumu, mīhini ahuwhenua, me ētahi atu. Ka hurihia te maitai waro-iti kounga teitei hei pereti angiangi hei hanga hua hōhonu pēnei i ngā kāpata motuka me ngā taupoki miihini; ka hurihia hoki hei pae, ā, ka whakamahia hei hanga i ngā wāhanga mīhini he iti te kaha e hiahiatia ana. Ko te maitai waro-iti te tikanga kāore e whakamahanatia i mua i te whakamahinga.

Ko ngā mea he nui ake te ihirangi waro i te 0.15% ka whakawarohia, ka whakakīia rānei ki te cyanide, ā, ka whakamahia mō ngā wāhanga pēnei i ngā pou, ngā pū, ngā sprocket me ētahi atu wāhanga e hiahia ana ki ngā pāmahana mata teitei me te ātete pai ki te kakahu.

He iti noa te whakamahinga o te maitai ngawari nā te iti o tōna kaha. Mā te whakanui tika i te nui o te manganese i roto i te maitai waro me te tāpiri i ngā iti o te vanadium, te titanium, te niobium me ētahi atu huānga whakarewa ka tino whakapai ake i te kaha o te maitai. Mēnā ka whakaitihia te nui o te waro i roto i te maitai, ā, ka tāpirihia he iti o te konumohe, he iti o ngā huānga hanga boron me te carbide, ka taea te whiwhi i tētahi rōpū bainite waro tino iti e kaha ana, ā, e mau tonu ana te kirihou me te pakari.

1.2. Maitai waro waenga

He maitai waro me te ihirangi waro o te 0.25% ~ 0.60%.

He maha ngā hua tae atu ki te maitai kua patua, te maitai kua patua-haurua, te maitai kohuatia me ētahi atu.

Haunga te waro, he iti iho pea te waro kei roto (0.70%~1.20%).

E ai ki te kounga o te hua, ka wehea kia rua ngā maitai hanganga waro noa me ngā maitai hanganga waro kounga teitei.

He pai te mahi tukatuka wera me te tapahi, engari he ngoikore te mahi whakarewa. He teitei ake te kaha me te pakeke i te maitai waro-iti, engari he iti iho te kirihou me te pakari i te maitai waro-iti. Ka taea te whakamahi tika i ngā rauemi hurihuri wera me ngā rauemi kume matao me te kore e whakamahanatia, ka taea rānei te whakamahi i muri i te whakamahanatia.

He pai ngā āhuatanga ā-pūkaha o te maitai waro waenga i muri i te tinei me te whakamahana. Ko te pakeketanga teitei rawa atu ka taea te whakatutuki ko te HRC55 (HB538), ā, ko te σb ko te 600~1100MPa. Nō reira, i roto i ngā whakamahinga maha me ngā taumata kaha waenga, ko te maitai waro waenga te mea e whakamahia whānuitia ana. Haunga te whakamahinga hei rauemi hanga, e whakamahia whānuitia ana hoki i roto i te hanga i ngā wāhanga ā-pūkaha.

Ngā Momo Maitai Waro Waenga

40, 45 maitai, maitai whakamate, maitai whakamate-haurua, maitai kohua…

Te Tūranga o te Maitai Waro Waenga

Ko te maitai waro waenga e whakamahia ana mō te hanga i ngā wāhanga nekeneke kaha-teitei, pērā i ngā pēhi hau me ngā piston papu, ngā impeller tāpine mamaoa, ngā toki mīhini taumaha, ngā noke, ngā taputapu, me ētahi atu, ngā wāhanga ātete-kakahu mata, ngā toki porotaka, ngā taputapu mīhini, ngā miro, ngā roera, ngā taputapu papa, me ētahi atu.

1.3. Maitai waro teitei

E kiia ana he maitai taputapu, kei roto he waro mai i te 0.60% ki te 1.70%, ā, ka taea te whakapakeke me te whakamakuku.

He mea hanga ngā hama, ngā rākau, me ētahi atu ki te maitai me te ihirangi waro o te 0.75%; ko ngā taputapu tapahi pērā i ngā wiri, ngā taputapu keri, ngā riipene, me ētahi atu he mea hanga ki te maitai me te ihirangi waro o te 0.90% ki te 1.00%.

Ngā momo maitai waro teitei

50CrV4 maitai: He momo maitai tino pīngore, he kaha hoki, ko te nuinga he mea hanga mai i te waro, te chromium, te molybdenum me te vanadium me ētahi atu huānga. He maha ngā wā e whakamahia ana hei hanga puna me ngā taputapu hanga.

65Mn maitai: He maitai kaha, he pakari hoki tēnei, he mea hanga mai i te waro, te konupūmā me ētahi atu huānga. He maha ngā wā e whakamahia ana hei hanga puna, maripi me ngā wāhanga miihini.

75Cr1 maitai: He maitai taputapu waro-teitei, konupora-teitei, ko te nuinga he mea hanga mai i te waro, te konupora me ētahi atu huānga. He tino pakeke, he ātete hoki ki te kakahu, ā, e whakamahia ana hei hanga mata kani me ngā mea whakamatao.

Maitai C80: He momo maitai waro-teitei, he mea hanga te nuinga mai i ngā huānga pēnei i te waro me te konupora. He maha ngā wā ka whakamahia hei hanga i ngā wāhanga kaha-teitei pēnei i ngā mata kani, ngā pereti koiri me ngā puna.

Te Tūranga o te Rino Waro Teitei

Ko te maitai waro-teitei te mea e whakamahia nuitia ana mō

1. Ngā wāhanga waka
   E whakamahia ana te maitai waro-teitei ki te hanga i ngā wāhanga pēnei i ngā puna motuka me ngā pahu pēki hei whakapai ake i te haumaru me te mahi a te waka.
2. Ngā maripi me ngā mata
   He tino pakari, he tino kaha hoki te maitai waro-teitei, ā, e whakamahia ana hei hanga taputapu tapahi me ngā whakaurunga, hei whakapai ake i te pai o te tapahi me te whakaroa i te roa o te mahi.
3. Ngā taputapu hanga
   Ka taea te whakamahi i te maitai waro-tiketike ki te hanga i ngā matihao hanga, i ngā taputapu hanga matao, i ngā matihao wera, me ētahi atu, hei whakapai ake i te tika me te kaha o te hua kua oti.
4. Ngā wāhanga mīhini
   Ka taea te whakamahi i te maitai waro-tiketike ki te hanga i ngā wāhanga mīhini maha, pērā i ngā peera, ngā taputapu, ngā pokapū wira, me ētahi atu, hei whakapai ake i te pai o te mahi me te kaha ki te kawe kawenga.

(2) Te whakarōpūtanga mā te hanganga matū

Ka whakarōpūtia te maitai i runga i tōna hanganga matū, ā, ka taea te wehewehe ki te maitai waro me te maitai koranu.

2.1. Te maitai waro

He koranu rino-waro te maitai waro, ā, he 0.0218%~2.11% te nui o te waro. E kiia ana hoki ko te maitai waro. He iti noa iho te silicon, te manganese, te whanariki, me te phosphorus kei roto. I te nuinga o te wā, ko te nui ake o te waro i roto i te maitai waro, ko te nui ake o te pakeke me te kaha, engari ko te iti ake o te kirihou.

2.2. Rino koranu

Ka hangaia te maitai koranu mā te tāpiri i ētahi atu huānga koranu ki te maitai waro noa. E ai ki te nui o ngā huānga koranu ka tāpirihia, ka taea te wehewehe i te maitai koranu ki te maitai koranu iti (te tapeke o ngā huānga koranu ≤5%), te maitai koranu waenga (5%~10%) me te maitai koranu teitei (≥10%).

Me pēhea te whiriwhiri i te kani matao tika

Rauemi tapahi: He pai te kani matao maroke mō te tukatuka i te maitai koranu iti, te maitai waro reo me te iti, te rino maka, te maitai hanganga me ētahi atu wāhanga maitai he iti iho i te HRC40 te pakeke, inā koa ngā wāhanga maitai kua whakarerekētia.

Hei tauira, te maitai porowhita, te maitai koki, te maitai koki, te maitai hongere, te ngongo tapawhā, te kurupae-I, te konumohe, te paipa kowiri tira (me whakakapi he pepa kowiri tira motuhake ina tapahia te paipa kowiri tira)

Ngā ture whiriwhiri māmā

1. Tīpakohia te maha o ngā niho o te mata kani kia rite ki te whānui o te rauemi tapahi

2. Tīpakohia te raupapa mata kani kia rite ki te rauemi
