Ngā Wāhi Mamae o te Whakakanapa i te Mold
E mōhio ana te hunga kua mahi i roto i te umanga pokepokea mō te neke atu i te tekau tau, ahakoa he māmā te whakakanapa, he tino uaua. He maha ngā kaihanga pokepokea e kite ana ko te tukanga whakakanapa te mea tino uaua - he roa te wā, he koretake ngā hua, ā, e whakawhirinaki ana ki te wheako o te tohunga hangarau. He pono rawa tēnei i nāianei, me te piki haere o te kanorau o ngā rauemi pokepokea, mai i te maitai P20 tuku iho ki te S136 pakeke-teitei, tae atu ki ngā rauemi carbide me te uku sima. He maha ngā wā ka hē ngā rauemi me ngā tukanga whakakanapa tuku iho. I kī mai te kaiwhakahaere awheawhe whakakanapa o tētahi wheketere pokepokea tika i Shenzhen ki ahau, "I mua, i whakamahia e mātou te boron carbide me te paura taimana, he pai te mahi, engari he nui rawa te utu; he maha ngā wheketere iti kāore i taea te utu. He ngawari te paura corundum noa ki te karawarawa, ā, i ētahi wā, i muri i te whakakanapa, i raro i ētahi āhuatanga rama, kei te mau tonu ngā tohu kohu."
Ngā "Ngā Āhuatanga Motuhake" o te Paura Iti Alumina Whakakotahi Ma
Te takepaura moroiti alumina kua hanumi māKo te tino pai o te mahi whakakanapa pokepokea ai e whakatauhia ana e tōna "hanganga ira". Ko tōna wāhanga matua ko te α-konumohe waikura, neke atu i te 99%. He aha te tikanga o tēnei parakore? Ko te tikanga he iti ake ngā poke, ā, he iti ake te tūponotanga ka puta he karawarawa tūpono i te wā e whakakanapahia ana. He rite ki te whakakanapa i te rakau ki te pepa kirikiri pai; ki te mea he iti noa ngā kirikiri matotoru kei roto i te pepa kirikiri, ka pakaru te mata. Ko tētahi atu painga o te parakore teitei ko te pakeke ōrite. Ko te pakeke Mohs o te alumina mā kua whakaranua he 9.0, tuarua ki te taimana me te silicon carbide, engari ko tōna painga kei roto i te ōritetanga o tōna pakeke. E mārama ana te hunga e whakakanapa ana ki te mea he koretake te pakeke o ngā matūriki whakakanapa, ka pau tuatahi ngā matūriki ngawari, ā, ka puta ake ngā matūriki pakeke, ka ngāwari te puta he karawarawa. He "ōrite" te mahi a te paura moroiti alumina mā kua whakaranua i tēnei whakaaro.
Te Matatau o te Āhua o te Matūriki
I te tau kua hipa, i toro atu ahau ki tētahi wheketere hanga paura moroiti alumina mā i Jiangsu, ā, i whakakitea mai e te kaiwhakahaere hangarau he whakaahua whakatairite i raro i te karu hikohiko: "Tirohia, koinei tepaura moroiti alumina kua hanumi mā "Ka hangaia e mātou; he āhua hexagonal te nuinga o ngā matūriki, he porowhita rānei, ā, kua āta rongoatia ngā taha kia porowhita. Ko te paura moroiti parauri kua whakaranua ki te alumina noa, he āhua koretake, he koi hoki ngā taha." He mea nui tēnei rerekētanga i roto i te whakakanapa pokepokea ai. Ahakoa he kaha te tapahi o ngā taha koi, he ngāwari ki te whakararuraru; ko ngā matūriki porowhita, i tetahi atu taha, he rite ki te "hurihuri me te huri" te mahi i te "tapahi", he tino pai mō te whakakanapa i ngā pokepokea ai e hiahia ana kia tino teitei te mata. He nui ake te kitea o ngā painga o ngā matūriki porowhita i te wā e whakakanapahia ana ngā wāhi uaua ki te tae atu pērā i ngā mata piko me ngā kokonga o roto.
Te Toi o te Whakahaere Rahi Matūriki
He tino pai te whakahaere i te rahi o te matūriki e te paura moroiti kōrunuma mā. He maha ngā wā ka kiia ngā mea whakakoi tuku iho he "2000 mata" he "3000 mata" rānei, engari ko te mea pono, ka taea te horapa o te rahi o te matūriki mai i te 1500 mata ki te 3500 mata. Heoi, ka taea e te paura moroiti kōrunuma mā kounga teitei te horapa o te rahi o te matūriki. Hei tauira, ko te hua kua tapaina ko W7 (he rite ki te 2500 mata) neke atu i te 95% o ōna matūriki kei roto i te awhe W6.5-W7.5.
He aha te hiranga o te tohatoha whāiti o te rahi o te matūriki mō te whakakanapa pokepokea ai? Whakaarohia te tātari raihi me te tātari; ki te ōrite te rahi o ngā pata raihi, he maeneene te tukanga tātari; ki te rerekē te rahi, ka ārai ngā pata iti i ngā kōhao tātari. E pā ana te kaupapa kotahi ki te whakakanapa. Mā te paura iti me te rahi ōrite o te matūriki ka whakarite kia rite te tapahi i te wā o te whakakanapa, ka ārai i ngā āhuatanga e nui rawa te whakakanapa o ētahi wāhi, ko ētahi kāore i te tino whakakanapa.
Te Mahi i roto i ngā Whakamahinga Whaihua
I mua, e 35 hāora te roa o te whakakanapa i roto i tētahi kamupene i Guangzhou e hanga ana i ngā pokepoke mōkihi whakapaipai hei whakakanapa i tētahi huinga pokepoke ngongo rīpene ngutu kounga teitei. Whai muri i te huri ki te paura iti-kōrunuma mā, ka whakaitihia te wā ki te 22 hāora. I kī mai tā rātou tohunga whakakanapa ki ahau, "I mua, me tino tupato mātou i ngā wāhanga whakamutunga o te whakakanapa; ahakoa he hapa iti noa iho, ka nui rawa te whakakanapa, ka rakuraku rānei. Ināianei, me te paura iti-kōrunuma mā, he māmā ake te whakahaere i te tukanga whakakanapa, inā koa i ngā wāhanga whakamutunga, he nui noa iho ngā whitinga mārama hei whakatutuki i te āhua whakaata."
I roto i te mara o te whakakanapa pokepokea ai waea pūkoro, ko ngā painga opaura moroiti korundum māhe nui ake te kitea. Me tino teitei te mata o ngā anga waea pūkoro, i ētahi wā kei raro iho i te Ra 0.01 maikiromita. I whakahaerehia e tētahi wheketere i Dongguan e tohunga ana ki ngā pokepokea ai anga waea pūkoro tētahi whakamātautau whakatairite: i te wā i whakakanapahia ai ngā pokepokea ai konumohe, mā te whakamahi i te paura iti korundum mā i hua ake ai he 20% te whakahekenga o te taratara o te mata i whakaritea ki ngā rauemi whakakanapa tuku iho, me te whakaiti anō hoki i te wā whakakanapa mā te 15%. Ngā Whakamahinga Whakakanapa o ngā Rauemi Pokepokea Motuhake
I te whanaketanga o ngā rauemi pokepoke, kei te piki haere te rongonui o ngā rauemi pakari me te ātete ki te kakahu, ā, ka puta he wero hou mō te whakakanapa. Hei tauira, he maha ngā wā kāore e whai hua ngā rauemi whakakanapa tuku iho ina whakamahia ki ngā rauemi pēnei i te paura maitai tere-teitei me te karāhe sima. I pāngia tētahi wheketere pokepoke i Shanghai e ngā uauatanga i te tukatuka i ngā pokepoke tānga karāhe sima; i eke te pakeke o te pokepoke ki runga ake i te HRC70, ā, tata kore e whai hua ngā rauemi whakakanapa noa. I muri mai ka whakamātau rātou ki te whakamahi i te paura moroiti korundum mā me te whakapiri whakakanapa motuhake, ā, he tino pai ngā hua. I kī tā rātou kaiwhakahaere hangarau, "He nui te pakari o te paura moroiti korundum mā, ā, he tika ngā āhuatanga whakakoi-ake. I te wā o te tukanga whakakanapa, ka puta tonu ngā taha tapahi hou, ka mau tonu te pai o te whakakanapa."
Ngā Painga Ōhanga
He maha ngā rangatira o ngā wheketere pokepoke i āwangawanga i te tīmatanga mō te utu nui okōrunuma māpaura moroiti, engari ki te tirohia tata atu, ka kitea he pai ake ngā painga whānui. I tatauhia e te rangatira wheketere pokepoke i Taizhou, Zhejiang ngā utu mōku: i te tīmatanga, ko te utu mō te whakakanapa i tētahi huinga pokepoke kirihou rahi-waenga he tata ki te 800 yuan mō te mahi me ngā rauemi, e 8 hāora te roa; i muri i te whakamahi i te paura moroiti korundum mā, ahakoa i piki ake te utu rauemi mā te 100 yuan, i whakaitihia te wā ki te 5 hāora, ā, i heke iho ngā utu mahi mā te neke atu i te 200 yuan, ā, i heke iho te utu whānui mā te neke atu i te 100 yuan. I tua atu, i pumau ake te kounga o te mata, ā, i heke iho ngā amuamu a ngā kiritaki.
He mea nui ake, ka roa ake te roa o te ora o te pokepokea ai. Mā te tukanga whakakanapa tika ka taea te whakakore i ngā kapiti moroiti i runga i te mata o te pokepokea ai, me te whakaiti i te kukū o te ahotea. E whakaatu ana ngā raraunga ko ngā pokepokea ai kua whakakanapahia kia āta ki te paura moroiti korundum mā, he 15%-20% te roa o te ora. He mea nui tēnei mō ngā pokepokea ai e tekau, e rau mano rānei te utu.
Ngā Tohutohu Whakamahi me ngā Whakatūpato
Ahakoa he tino pai te mahi a te paura moroiti kōrundum mā, me whai tikanga motuhake mō tōna whakamahinga. I kōrero mai tētahi tohunga toi nō tētahi kamupene ratonga whakakanapa ngaio i Qingdao i ētahi wheako:
Ko te whakamahinga whakarōpū te mea nui. Kaua e whakamahia te rahi kirikiri kotahi mō te whakakanapa taratara me te whakakanapa pai; me haere mārire koe i roto i te raupapa "taratara-waenga-taratara". Hei tauira, ka taea e koe te tīmata ki te W40, ka neke mārire ki te W10, ā, hei whakamutunga ka whakamahia te W3.5, te paura iti pai ake rānei mō te whakakanapa pai. He mea nui te whiriwhiri i te kaikawe. Me whakamahi te paura iti kōrunuma mā me te whakapiri whakakanapa tika, te kaikawe wai rānei. He pai ngā kaikawe hinu mō te whakakanapa maitai, ko ngā kaikawe wai ia he pai ake mō ngā konganuku kore-ferrous. Ehara i te mea ka whakaratohia e te kaikawe te whakatārewatanga me te whakahinuhinu anake, engari ka tangohia hoki ngā paru kua tangohia.
Me taurite te pēhanga me te tere. Ehara i te mea he pai ake te pēhanga whakakanapa teitei ake; ka taea e te pēhanga nui te whakauru i ngā matūriki moroiti ki te mata o te mea mahi. I te nuinga o te wā, ko te rahi o te matūriki he iti ake te pēhanga, ā, ka taea te whakanui ake i te tere. Kāore e taea te wareware i te tukanga horoi. I ia wā ka whakarerekētia te rahi o te matūriki, me horoi pai te mata pokepokea me ngā taputapu whakakanapa kia kore ai e uru ngā matūriki matotoru ki te tukanga e whai ake nei. Ka whakamahia e ngā tohunga hangarau he karāhe whakanui hei tirotiro i te ma i muri i ia tukanga.
Ngā Auahatanga Whakawhanake Ahumahi
I runga i ngā kitenga mai i ngā whakaaturanga me ngā whakawhitiwhiti hangarau i ngā tau tata nei, he maha ngā au e puta ake ana i roto i te whakamahinga o te paura moroiti alumina mā ki te whakakanapa pokepokea ai: Kei te piki haere te rongonui o te whakaritenga. He maha ngā kaihanga paura moroiti e tīmata ana ki te tuku ratonga "hangaia kia rite ki te hiahia", e whakarato ana i ngā ōwehenga rahi matūriki motuhake o te paura moroiti alumina mā i runga i ngā āhuatanga pēnei i te rauemi pokepokea ai, ngā taputapu whakakanapa, me ngā whakaritenga whakaoti mata. Kua whakawhanakehia e ētahi he tātai motuhake mō ngā momo maitai rerekē.
Kei te piki haere te rongonui o ngā hua hiato. Kei te tīmata te puta mai o ngā hua whakakanapa e whakakotahi ana i te alumina mā me ētahi atu rauemi, pērā i tekonumohe māi konatunatua ki te waikura cerium, hei whakataurite i te kaha tapahi me te whakaotinga mata; ā, i konatunatua ki te paura iti taimana hei whakakanapa i ngā rauemi tino mārō. Kei te rongonui haere ngā hua hoa-taiao. I te pikinga ake o ngā whakaritenga taiao, kei te aro nuihia ngā hua paura iti alumina mā, kāore he konganuku taumaha, he iti te puehu, ā, he ngāwari te hangarua. Kua whakawhanakehia e ētahi kaihanga ngā pūnaha whakakanapa wairewa hei whakaiti i te whakamahinga o ngā whakarewa waro.
