Ko te tukanga mīti me te tukanga pāmahana teitei ka whakamahia ki nga waahi maha. Hei tauira, ko te tukanga maimoatanga wera he tukanga e whakamahana ana i nga taonga whakarewa, i o raatau hua ranei ki te pāmahana e hiahiatia ana, ka whakamatao i te tere me te tikanga kua tohua, ka huri i o raatau hanganga o roto, ka whiwhi i nga mahi e hiahiatia ana. Ko tenei momo tukanga e whakamahia ana i roto i te maha o nga waahi tukatuka hua ahumahi, engari me pehea te wera o te rakau piston? He aha ona tikanga maimoatanga wera? Ko te whakautu a Yantai Shunfa Component Pneumatic Co., Ltd.
Ko te kaupapa o te whakamaarama me te whakamaarama ko te whakarite kia mau nga taonga miihini matawhānui o te rakau piston e rite ana ki te kaha, te pakeke, te kirihou, me te pakari. Ko te hanganga o roto ko te sorbite riterite me te pai, kua rite mo te tiini mata o muri mai. Ko te roa o te rakau piston cylinder roa he 3800-4200 me te diameter o te Φ 90- Φ 110mm, no reira ka mau ona taputapu whakamahana i te oumu whakawera momo pai 150KW, he 600KW ranei i whakatarewa tonu te oumu whakawera whakawera, me te pāmahana e whakahaerehia ana i roto i nga rohe e rua: me raro. Tawhā tukanga maimoatanga wera: E wha ngongo e iri i roto i te oumu kotahi i roto i te oumu momo pai, ki te pāmahana whakawera tinei o 830 ± 10 ℃. I muri i te pupuri mo te 160 meneti, ka tineia nga ngongo i nga wa e rua, me nga ngongo e rua ka tineia ia wa. Ka whakamahia te wai whakamatao whakamatao ki te whakamatao i nga ngongo, ka oho ki runga, ki raro i te wa e tineia ana kia pai ake ai te whakamatao. Ka whakamatao ki te 100 ℃ (ka puta te mamaoa o nga rakau engari karekau e mirumiru), ka rere te wai ki roto i te oumu whakamahana momo puna hei whakamahana.
Kia wha nga ngongo ka whakamahana i te 550 ± 10 ℃ i te wa kotahi, ka pupuri mo te 190 meneti, ka whakamahana i mua i te whakamatao o te wai. I muri i te tukanga o runga tineia me te tempering maimoatanga, te mahi iu, a ka rere ke te pakeke i waenganui i 210-255HBS. He nui ano te rereketanga o te pakeke i waenga i nga waahanga o runga, o waenga, o raro o te rakau piston kotahi. A, i etahi wa he whakamahana takitahi me te pakeke kore, te kaha iti ranei e hiahia ana ki te whakatikatika. He nui te ahua o te whakaheke, ka piki ake te uaua o te whakatikatika me te tukatuka miihini. Na te ngoikore o te kaha o te 45 maitai, ko te hanganga o roto e kitea ana e te metallography ehara i te mea kotahi me te riterite te tempered sorbite, engari he nui te nui o te sorbite kore utu kei roto i tona pokapū, me etahi waahanga he whatunga o te sorbite me te hanganga Widmann.
Hei whakaoti i nga raruraru i runga ake nei, ka whakamahia e matou he whakamaarama maimoatanga wera tonu me te oumu whakamahana mo te whakamahana me te whakamahana, me te 2 ngongo kua whakauruhia mo ia ngongo. I muri i te whakamahana me te whakamahana, ka tineia te oumu, ka mahia kia kotahi te ngongo mo ia paati kia pai ai te whakamahana. Ki te whakaaro ko te pāmahana Ac3 o te 45 maitai ko te 770-780 ℃, hei whakamahine i te witi me te whakaiti i te deformation i te mea ka taea, ka tango matou i te 790 ± 10 ℃ te tukanga tiini intercritical ki te whakamahine i te witi austenite, me te whiwhi pai me te rite te kihu Flat. martensite i muri i te tinei, kia pai ake ai te kaha me te uaua o te rakau piston. Hei whakaiti ake i te whakarereketanga me te whakapai ake i te riterite whakamahana o te otinga tinei, i tapirihia e matou te 5% -10% nga taapiri tiini ki te wai pai. I te wa o te tinei, i whakamahia ano e matou he papu wai huri hei tohe i te wairewa whakamatao kia rere mo te whakamatao. Kei te wera tonu te whakamahana ki te 550 ± 10 ℃, me te rite tonu o te rangi tinei i mua. I muri i te whakamahana, ka whakamataohia e te wai kia kore ai e puta mai te ahua tuarua o te pakarutanga o te whakamahana. I muri i te whakapai ake o te tukanga i runga ake nei, he rite te hanganga o roto me te pai o te sorbite, me te tangohanga o te ferrite nui, reticular ranei me te hanganga Widmann, ka puta he kakahu me te pakari me te kaha.
