Te tohu i ngā mīhini horoi papatahi

"Me tohu ngā mīhini horoi papatahi?" "Kāore?"

"E hiahiatia ana e rātou?"……

I tēnei rā ka kōrero mātou mō tēnei take ki a koutou, tera pea he tokomaha o te umanga ka whakaaro"Xiaowan ā, he ahua kore ngaio koe ……".

E mōhio ana tātou katoa, ko ngā mīhini horoi papatahi hei hononga whakapiri he mea nui te urunga, ā, he mea nui tēnei ki te whakanui ake i te horahanga pa, me te whakamarara i te pēhanga pa. Ko te nuinga o ngā mīhini horoi papatahi e whakamahia ana i roto i te huihuinga ahumahi kāore he tohu pērā i te mea kei te pikitia i raro nei.

Nā, he aha ngā take ka tohua ai ngā mīhini horoi papatahi?

(1) Me karo te whare whakaputa i te whakaranu rauemi

Mō te tukanga whakaputa o te whakakikoruatanga rīpene whaiti, ka whakamahia ngā mīhini horoi papatahi hei tohu i te mata o te mīhini horoi papatahi kia kore ai e puta he momo rauemi rerekē, kia kore ai e puta he raruraru rauemi i roto i te tukanga whakaputa, i te tukanga whakawhiti rānei, ā, he tikanga whakahaere tukanga tēnei. Hei tauira, ko te"304"kei roto i te pikitia e whai ake nei, arā, ko te rauemi A2 te mea e whakamahia ana mō te mīhini horoi papatahi. Mena ka hangaia e te kaihanga he mīhini horoi papatahi o te whakatakotoranga ōrite i roto i te rauemi 316 i te wā kotahi, ka taea te tohu i te mīhini horoi ki"316"or "A4".

He mea noa tēnei tohu o te tautuhi rauemi i roto i ngā mīhini horoi papatahi kowiri tira, ko te take he mea noa i muri i te hanga o ngā hua kowiri tira i muri i te horoinga me te whakakorenga, ā, mai i te āhua mā kanapa, kāore e taea te wehewehe i te rauemi.

He mārama te rauemi i runga i te mata o te kowiri tira, ā, ka taea e ngā mīhini horoi papatahi te karo i te tukanga whakaputa, huihuinga rānei o ngā rauemi whakauru.

(2) ngā whakaritenga paerewa

Ko ētahi paerewa hua e tohu ana i ngā whakaritenga mō ngā mīhini horoi papatahi kua tohua, hei tauira, te paerewa"EN", "EN", "EN", "EN", "EN"me"EN".

Hei tauira, ko te paerewa"EN 14399-5 (GB / T 32076.5) hononga hanganga pūmau kaha-teitei kua utaina i mua Wāhanga 5: ngā horoi papatahi"me tohu ngā mīhini horoi papatahi kua tineia, kua whakamaroketia hoki ki te kōpiko, e whakaaturia ana i raro nei:

Hei tauira, ko te paerewa"Ngā Horoi Rino Whakapakeke ASTM F436"e tohu ana me tohu ngā mīhini horoi papatahi e whai ana i tēnei paerewa ki te"F436"tohu, e whakaaturia ana i raro nei:

Ka taea te whakatakoto i ngā mīhini horoi papatahi kua tohua, kāore rānei i tohua ki te paerewa?

Ki te titiro ki ngā paerewa hua o nāianei, kāore i te mārama te tautuhi i ngā paerewa mō ngā mīhini horoi papatahi mēnā me tākaro te tohu.

Paerewa ISO 898-3:2018 (ngā āhuatanga ā-pūkaha o ngā whakapiri – ngā horoi papatahi) Ko te paerewa te whakatinanatanga o ngā whakaritenga mahi mō ngā horoi papatahi rauemi maitai waro, maitai koranu i te tau 2018, ā, i roto i te upoko 9.2 mō te tohu horoi papatahi i whakamāramahia ngā whakaritenga.

Ko te tohu mō te horoi papatahi kei te whakaaro o te kaihanga, kei te whakaaetanga rānei i waenga i te tuku me te tono.

Kaua ngā mīhini horoi papatahi e tohua ki ngā reta whakaara. Kāore i te tūtohutia te tohu kōpiko nā te mea ka taea te whakarerekē i te whanaungatanga kaha taipana-piri o te hononga pūtu-nati, te hanga rānei i ngā kukū ahotea ka pakaru pea te mīhini horoi.

E whakaatu ana ngā kōrero e rua i runga ake nei, ehara i te mea me tohu ngā mīhini horoi papatahi, ā, kei te kaiwhakarato te whakatau, te whiriwhiri rānei mēnā me tohu i mua i te tono. Kāore i te tūtohutia kia tohua te mata o ngā mīhini horoi papatahi ki ngā tohu whakairo, ki ngā tohu kōpiko rānei.

Me whakamātau te tohu kōpiko o te mata horoi papatahi o te kowiri tira austenitic ka huri i te hononga taipana-kaha honohono pūtu – nati. He mea tino pono, nā te iti o te pakeke o te kowiri tira austenitic, kāore te tohu kōpiko e arahi ki te kukū o te ahotea i roto i te horoi, e kore hoki e pakaru te horoi.
