Ngā Painga Mahi me te Aratohu Āhua Mahi mō ngā Koranu Whakamahana Nikara-Kōrohiuma-Tiketike

1. Whakataki kiNichrome 70/30 He koranu whakamahana mahi-teitei me te nui o te chromium

1.1 Te Hanganga Taketake me te Tūnga o te Hua

Ko te Nichrome 70/30 (te karaehe Cr30Ni70, e mōhiotia ana ko te Ni70Cr30) te momo konukōmiuma-tiketike i roto i te whānau koranu whakamahana nichrome, me te hanganga iti o te 70% nikara me te 30% konukōmiuma me ngā poke e tino whakahaeretia ana pērā i te rino me te waro. Kua whakarōpūtia hei koranu whakamahana ātete kounga ahumahi teitei.

E tutuki ana tēnei koranu i ngā paerewa maha o te motu me te ao, tae atu ki te GB/T 1234, ASTM B344 me te DIN 17470. He rauemi matatau tēnei e whakataurite ana i te pumau o te pāmahana teitei, te ātete ki te waikura me te tika o te ātete, e pai ai mō ngā āhuatanga whakamahana pāmahana teitei me ngā āhuatanga mahi uaua.

1.2 Ngā Āhuatanga Mahi Matua e Whā

Te pāmahana ratonga teitei akeKa tautoko i te pāmahana mahi tonu mō te wā roa tae atu ki te 1250°C me te pāmahana tihi mō te wā poto o te 1300°C, he teitei ake i te momo Nichrome 80/20 noa.

Te ātete hiko teitei akeKo tōna ātete pāmahana rūma he tata ki te 1.18 μΩ·m, he iti hoki te tauwehenga ātete pāmahana. He ngawari te piki me te heke o te mana i te wā e whakamahana ana, e āhei ai te tika o te whakahaere pāmahana.

Te kaha o te waikura me te ātete ki te waikura matomatoKo te nui o te chromium ka hanga i tētahi kiriata tiaki waikura kiato ake i ngā pāmahana tiketike, e tuku ana i te mahi tino pai i roto i ngā hau whakahāwea/whakaiti tauutuutu, ā, ka whakaroa ake i te roa o te mahi a te huānga.

Ngā āhuatanga miihini pāmahana-tiketike pumauHe tino ātete ki te ngokingoki me te ātete ki te whakarerekē i ngā pāmahana teitei. Kāore e ngāwari te totohu, te whakapē rānei i muri i te whakamahinga roa, kia pai ai te pumau o te hanganga o ngā wāhanga whakamahana.

2. Ngā Horopaki Taupānga Ahumahi Matua e Ono o te Nichrome 70/30

2.1 Ngā Wāhanga Whakamahana mō ngā Oumu Maimoatanga Wera Ahumahi Tino Pai

Koinei te whakamahinga matua o te Nichrome 70/30, inā koa mō ngā oumu ātete pāmahana teitei o te akomanga 1200°C, ngā oumu whakapūkara, ngā oumu pere me ngā oumu whakamahana.

Ahakoa te uaua o ngā āhuarangi oumu me ngā piki me ngā heke o te pāmahana, ka taea e tōna ātete nui ki te waikura me te waikura o te āhuarangi te whakaroa ake i te roa o te ratonga waea whakamahana, e 40% te roa ake i ngā koranu noa.

2.2 Te Whakamahana i te Pūwero i roto i ngā Ahumahi Karāhe me te Uku

He teitei te pāmahana me te hau kohu kawakore i roto i ngā rohe whakamahana o ngā oumu rewa karāhe me ngā oumu whakarewa uku, ā, he tino waikura ēnei ki ngā rauemi whakamahana.

Ko te tauira konukōmiuma teitei o te Nichrome 70/30 ka pai ake te ātete ki te horo o te hau kawakore, ka pupuri i te mana whakamahana pumau, ka whakarite i te ōritetanga o te pāmahana puta noa i ngā rohe oumu, ā, ka whakaiti i te wā kore e whakamahia mō te whakakapinga huānga.

2.3 Ngā Wāhanga Whakamahana mō te Hanganga Ārahi me te Hikohiko

Ko ngā tukanga pēnei i te whakamahana i te anga haurua-haurua, te herea o te pēhanga wera mōkihi me te sintering wāhanga hiko e whakatakoto ana i ngā whakaritenga tino tiketike mō te ōritetanga o te pāmahana me te ma.

He pumau te ātete o tēnei koranu, ā, he ōrite te whakaputanga wera, he iti hoki ngā mea pūngāwerewere i ngā pāmahana teitei, ā, e kore e poke i te taiao tukanga. He maha ngā wā ka hangaia hei tokotoko whakamahana tika me ngā pereti whakamahana mō ngā taputapu hanga hiko teitei.

2.4 Ngā Ātete Tika me ngā Huānga Pūoko

Nā te iti o te ātete pāmahana me te tino pai o te pumau ātete mō te wā roa, ka whakamahia te Nichrome 70/30 ki te hanga i ngā ātete waea tino tika me ngā matua ātete mō ngā pūoko hāora motuka.

Ka tutuki i tana mahi te whakaritenga pakari o te ātete taumata-hoia TCR ≤ 50 ppm/°C, me te pupuri tonu i te ātete pumau puta noa i te awhe pāmahana whānui.

2.5 Ngā Taputapu Whakamahana Whare me te Arumoni Utu-teitei

Ko te Nichrome 70/30 anō hoki te rauemi pai mō ngā oumu kounga teitei, ngā pū wera ahumahi, ngā pokepokea hanga wera kirihou me ētahi atu hua arumoni/whare e hiahia ana kia roa te wā whakamahana me te pumau teitei.

Ki te whakaritea ki te waea nichrome noa, he nui ake te tu atu i ngā huringa makariri-wera, ā, he iti noa te whakahekenga mana i muri i te whakamahinga roa, ka pai ake te pono o te hua whānui.

2.6 Te Whakamahana Motuhake i roto i ngā Ahumahi Matū me te Whakarewa

I ngā horopaki pērā i te whakamahana waikura i roto i te ahumahi matū me ngā oumu rewa tauira i roto i te ahumahi whakarewa, ka ngāwari te pakaru o ngā rauemi noa.

He pai te ātete o te Nichrome 70/30 ki ngā momo āhuarangi waikawa me te kawakore, ā, ka taea te mahi pumau i roto i ngā taiao pāmahana teitei me te waikura ngawari, ka whakawhānui ake i te rohe tono o ngā koranu whakamahana hiko.

3. Ngā Rerekētanga Matua i waenga i te Nichrome 70/30 me ētahi atu koranu raupapa Nichrome

3.1 Whakataurite i ngā Tawhā Nichrome Alloy Matua

Hei whakaatu ā-kanohi i ngā rerekētanga, ka whakatauritehia e te ripanga i raro nei ngā tohu matua o ngā koranu nichrome ahumahi e toru e whakamahia whānuitia ana:

3.2 Te Tātari Hōhonu o ngā Rerekētanga Matua

Ngā rerekētanga mai i te Nichrome 80/20:Ko te nichrome 80/20 te koranu nichrome tino rongonui mō te whakamahinga whānui. He nui ake te ihirangi nickel, he pai ake te ngāwari o te hanga, ā, he iti te utu, he pai mō te nuinga o ngā āhuatanga whakamahana tuku iho i roto i te taiao hau.

He 10 ōrau teitei ake te nui o te chromium o te Nichrome 70/30. Ka whakatakahia e ia tētahi wāhanga o tōna ngāwari hei utu mō te pāmahana ratonga teitei ake, te ātete waikura kaha ake me te ātete waikura o te āhuarangi. He pai ake mō ngā āhuatanga ahumahi me ngā āhuarangi oumu uaua, ngā pāmahana teitei ake me ngā whakaritenga roa ratonga pakari.

Ngā rerekētanga mai i te Nichrome 60/15:Kei roto i te Nichrome 60/15 tētahi nui o te rino, he iti ake te utu, ā, he ātete taurite. E whakamahia ana mō te whakamahana pāmahana waenga-iti i raro i te 1000°C, ngā waea whakamahana taputapu whare noa, me ngā ātete potentiometer.

Kāore rawa he rino i roto i te Nichrome 70/30, ā, he tino pai rawa atu tōna pumau i te pāmahana teitei me te ātete ki te waikura. He pai mō ngā mahi ahumahi teitei, me te āputa mārama i roto i ngā tikanga mahi e tika ana.

4. Ngā Tohutohu Kōwhiringa mō ngā Āhuatanga Mahi Rerekē

Te taiao hau tuku iho, i raro i te 1100°C, he kaupapa matua mō te utu itiKōwhiria te Nichrome 80/20 i te tuatahi. He taurite te mahi whānui me te utu hoko pai ake.

1100–1200°C te pāmahana teitei, te āhuarangi oumu e rerekē ana, te roa o te ora e hiahiatia anaKōwhiria te Nichrome 70/30 i te tuatahi. He iti ake te utu whānui mō te whakamahinga roa.

I raro i te 1000°C, ngā taputapu whare i hangaia nuitia, he iti noa te utuHe kōwhiringa te Nichrome 60/15. Ka tutuki i a ia te hiahia whakamahana taketake me te penapena tino pai.

Ngā hau waikura kaha pērā i te whanariki, te kohu kawakore rāneiKāore i te tūtohutia ngā koranu nichrome noa. Whakaritea te aromatawai i ngā koranu Nichrome 70/30, i ngā koranu motuhake kounga teitei ake rānei.
