Pereti Kākahu Bi-whakarewa me te NM400: He aha te rerekētanga, ā, ko tēhea te mea hei whiriwhiri?

I roto i ngā ahumahi e mau tonu ana te riri o te pakū—te keri, te sima, te maitai, te whakahaere papatipu—he mea nui te whiriwhiri i te pereti kakahu tika. Ko ētahi o ngā kōwhiringa e whakaarohia whānuitia ana ko te NM400 mengā pereti kakahu whakakikorua chromium carbide bimetallic(e kiia ana ko ngā pereti CCO). Ahakoa e tapaina ana ēnei e rua he "ātete-mau", he rerekē rawa atu rāua i roto i te tukanga hanga, te whanonga i roto i te ratonga, me ngā tono mahi tino pai.

Te Hanganga: Te Rino Koranu me te Hangarau Whakakikorua Whakapiripiri

He pereti maitai koranu kotahi te NM400—kua hangaia ngā āhuatanga ātete-kakahu ki roto i te pereti katoa i te wā e whakarewahia ana, e whakamahanahia ana hoki. Ko te pakeketanga (~400 HB) ka puta mai i tētahi hanganga martensitic kua whakapakeketia i hangaia mā te tinei me te whakapakeke.

He rerekē,ngā pereti kakahu bimetallicka hangaia mā te whakapiri i tētahi paparanga konukōmiuma-tiketike ki runga i tētahi turanga maitai ngawari mā te whakamahi i te whakarewatanga pewa-tuwhera, pewa-uru rānei. Ka hangaia he hanganga paparanga-rua kei reira te paparanga paparanga o runga he kukū matotoru o ngā warowaiha Cr7C3, e tuku ana i te pakeketanga o te mata tae atu ki te HRC 58-65.

Ka tīmata te rerekētanga o te hanganga i te taumata whakanao, ka hua ake he tino rerekētanga o te mahi ā-marae.

Whakataurite Hanganga: Rino Kotahi-Wāhanga me te Paparanga Mahi

 He aha i roa ake ai te ora o ngā pereti CCO

● Hoahoa Paparanga mō te Roa o te Ora

Me ngā whirihoranga whakaritenga pēnei i te 3+3mm, 4+6mm, tae atu ki te 6+8mm (turanga + paparanga),Ngā pereti CCOko te mata anake e patua ana, ko te pereti turanga ia e tautoko ana i te hanganga i muri i te paunga o te paparanga kakahu. Ka kakahuria ōritetia te NM400—kia pau te mata, me whakakapi katoa te pereti.

● Ngāwari o te Whakatika me te Tiaki

He māmā ake te tukatuka i ngā pereti NM400 mā te whakamahi i ngā tikanga whakarewa me te piko paerewa. Ka taea te whakatika i ētahi pereti kakahu me ngā wāhanga kakahu rua-whakarewa, pērā i ngā roera, ngā niho kuru, me ngā waru, mā te whakahou i te paparanga kakahu, kia roa ake ai te ora o ngā wāhi tino nui me te kore e hiahiatia he whakakapinga katoa.

Āhea te Whakamahi i ia Mea: Te Taurite i ngā Rauemi ki te Whakamahinga

Kōwhiria te NM400 ina:

E hiahiatia ana te ātete pānga teitei

Kāore te taiao kakahu i te tino kino

He mea nui te ngāwari o te hanga me te hanga

Kōwhiria te Pereti CCO Bimetallic ina:

Te aro atu ki ngā taumata tiketike o te pahekeheke (hei tauira,ngā arai paraikete, ngā pekepeke, ngā awhiowhio)

Ko te roa o te ora ratonga he kaupapa matua mō te utu

Ngā Whakaaro Whakamutunga: Te Mahi i tua atu i te Pakari

Kāore te pakeketanga anake e whakatau i te roa o te mau. He mea nui ake ngā tikanga hanga, te hanganga iti, me te rautaki paparanga i ngā wā maha. Koia te take ka taea e ngā pereti mau whakakikorua chromium carbide te whakaputa i te uara huringa ora pai ake i raro i ngā tikanga tika.

I te wā e whiriwhiri ana i waenga i te NM400 me te pereti ātete-mau bimetallic, whakaarohia:

Tō taumata pakū

Taiao pānga

Ngā utu mō te wā kore mahi

Ngā āheinga hanga

Mā te iti o te panonitanga ki ngā rauemi kua whiriwhiria, ka rerekē pea te mahi me te utu katoa o te mana whakahaere.
