Pereti maitai 12L14: he māngai tino pai mō te maitai tapahi kore mahi teitei
I roto i te ao hanga ahumahi hou, ka pā tika te mahi a te maitai ki te kounga me te whai huatanga o te whakaputa hua. Hei maitai hanganga tapahi kore mahi teitei, kua waiho te pereti maitai 12L14 hei whiringa pai mō ngā mīhini tika, ngā wāhanga motuka, ngā taputapu hiko me ētahi atu ahumahi nā tōna hanganga matū ahurei me ōna āhuatanga tukatuka pai rawa atu.
1. Te hanganga matū: te kaupapa matua o te mahi tino pai
Ko te mahi motuhake o te pereti maitai 12L14 i ahu mai i tōna hanganga matū i ata hangaia. Ko te nui o te waro e tino whakahaeretia ana i te ≤0.15%, e whakarite ana i te pakari me te ngāwari o te rauemi; ko te nui ake o te konupora (0.85 – 1.15%) ka whakarei ake i te kaha me te ātete ki te kakahu; ā, ko te nui o te silicon he ≤0.10%, e whakaiti ana i te pokanoa o ngā poke ki te mahi. Hei tāpiri, ko te tāpiri o te whākawa (0.04 – 0.09%) me te whanariki (0.26 – 0.35%) ka whakapai ake i te mahi tapahi; ko te tāpiri o te mata (0.15 – 0.35%) ka whakaiti ake i te ātete tapahi, ka māmā ake te pakaru o ngā maramara, ā, ka whakapai ake i te pai o te tukatuka me te roa o te ora o te taputapu.
II. Ngā painga mahi: me te whai whakaaro ki te tukatuka me te tono
1. He tino pai te mahi tapahi: Ka taea te kī ko te pereti maitai 12L14 he "hoa pai mō te tukatuka miihini". He iti ake i te 30% te ātete tapahi i te maitai noa. Ka taea e ia te tapahi tere me te tukatuka whāngai nui. He pai te mahi i runga i ngā mīhini hurihuri aunoa, ngā taputapu mīhini CNC me ētahi atu taputapu, ka whakapoto i te huringa tukatuka me te whakaiti i ngā utu whakaputa.
2. Kounga mata pai: Ka taea e te whakaotinga mata o te pereti maitai 12L14 kua tukatukahia te eke ki te Ra0.8-1.6μm. Kāore e hiahiatia he maimoatanga whakakanapa uaua i muri mai. Ka taea te whakahaere tika i te whakakikorua hiko, te rehu me ētahi atu tukanga maimoatanga mata, e kore e whakarite noa i te āhua o te hua, engari ka whakapai ake hoki i te pai o te whakaputa.
3. Ngā āhuatanga ā-pūmau: Ko te kaha kume o te pereti maitai kei roto i te awhe 380-460MPa, ko te roanga he 20-40%, ko te whakahekenga whakawhiti-wāhanga he 35-60%, ā, he pakeke taurite (āhua huri-wera 121HB, āhua huri-matao 163HB). Ka taea e ia te pupuri i ngā āhuatanga ā-pūmau i raro i ngā āhuatanga mahi rerekē, ā, ka tutuki i ngā hiahia whakamahinga o ngā horopaki rerekē.
4. Te tiaki taiao me te haumaru: Ko te pereti maitai 12L14 e tino whai ana i ngā paerewa tiaki taiao o te ao, kua paahitia te tiwhikete taiao SGS a te EU me te tiwhikete taiao a Huiterangi, kāore he matū kino pēnei i te mata me te mercury, ā, e hangai ana ki te ia whanaketanga o te hanga matomato hou.
III. Ngā Whakatakotoranga me ngā Paerewa: Whakahāngai ki ngā hiahia maha
He whānuitia ngā whakaritenga mō te pereti maitai 12L14. Ko te matotoru o te pereti maitai hurihuri wera he 1-180mm, ko te matotoru o te pereti maitai hurihuri matao he 0.1-4.0mm, ko te whānui tikanga he 1220mm, ā, ko te roa he 2440mm, ka taea te whakarite kia rite ki ngā hiahia o te kiritaki. Mō ngā paerewa, e rite ana ki ngā paerewa o te ao pēnei i te AISI 12L14 i te United States, SUM24L i roto i te JIS G4804 i Hapani, me te 10SPb20 (1.0722) i roto i te DIN EN 10087 i Tiamana, e whakarite ana i te maha o ngā hua ka taea te whakamahi me te whakawhiti i te mākete o te ao.
IV. Ngā mara tono: Te whakamana i te whakapai ake i ngā ahumahi
1. Te hanga waka: e whakamahia ana hei hanga i ngā wāhanga tino tika pērā i ngā pou taputapu pouaka miihini, ngā whare weronga wahie, ngā whāriki pūoko, me ētahi atu, hei whakarite i te whakahaere pai o ngā pūnaha hiko waka me ngā pūnaha whakahaere hiko.
2. Ngā taputapu hiko me ngā taputapu tika: Koinei te rauemi pai mō te hanga hua tino tika pērā i ngā taputapu mataaratanga, ngā taputapu pokanga hauora, me ngā tīwiri whakatikatika taputapu whatu, hei āwhina i ngā taputapu hiko me ngā taputapu tika kia iti ake te hanga me te tino tika.
3. Te hanga miihini: He mahi nui tāna i roto i te hanga i ngā wāhanga pēnei i ngā matua takirere waipēhi, ngā pupuri whāriki, me ngā pine hono o ngā taputapu aunoa, ā, ka whakapai ake i te pumau me te roa o ngā taputapu miihini.
4. Ngā mea e hiahiatia ana i ia rā me ngā taonga kaihoko: E whakamahia whānuitia ana i roto i ngā taputapu tāonga papai, ngā raka, ngā hua hiko iti-toru me ētahi atu hua, me te whakaaro ki te mahi me te ataahua.
Hei maitai kounga teitei e whakauru ana i te mahi teitei, te tukatuka ngāwari, me te tiaki taiao, kei te akiaki te pereti maitai 12L14 i te umanga hanga hou kia neke ki te whai huatanga teitei, te tika, me te matomato me ōna painga ahurei, ā, kua noho hei pou tokomanawa nui mō te maha o ngā umanga ki te whakatutuki i ngā putanga hangarau me te auahatanga hua.
