Te Mātāpono o te Mīhini Tapahi Ranu Taiaho-Oxyfuel

Ko te tapahi hiato mura taiaho e pā ana ki "tapahi hāora taiaho", tētahi o ngā tukanga tapahi matua o te taiaho (ko ētahi atu e rua ko te tapahi rewa taiaho me te tapahi mimiti taiaho). Ehara i te mea ko te "mura i hangaia e te taiaho," engari he tukanga ranu e whakamahi ana i te taiaho hei pūtake wera, me te tāpiri atu ki te hāora parakore hei hau āwhina, hei tīmata i te tauhohenga mura waikura kaha (arā, "mura") i roto i ngā konganuku (ko ngā rauemi maitai te nuinga) i te wā o te tukanga tapahi. Ka whakamahia e tēnei tukanga te pūngao wera mai i te tauhohenga matū hei whakarei ake i te mahi tapahi.

Muri iho, ka whakamāramahia e mātou tōna mātāpono mai i ētahi tirohanga maha:

Mātāpono Matua: Te tahunga whakarewa whakahaeretia e te rēseri

1. Te mahi a te rēseri (te whakakā me te tiaki):

• Ka arotahihia he hihi taiaho kiato-pūngao teitei ki te mata o te mea mahi, ka tere te piki o te pāmahana o te konganuku kua whakamātaohia ki tōna pūwāhi mura (tata ki te 1350°C mō te rino).
• Ka whakaratohia e te hihi taiaho he pūtake wera tonu, tika, he nui te pūngao e kore e whakakā noa i te tauhohenga, engari he mea nui ake, ka pupuri i te wāhi tauhohenga i te pāmahana tiketike.

2. Te tūranga o te hāora (te kaitahu me te kaihoroi):

• Ka werohia ngātahitia te rerenga kotahi o te hāora pēhanga teitei, parakore teitei me te hihi taiaho ki runga i te wāhi whakarewa kua werahia e te taiaho.
• Ko te rino (Fe) e tae atu ana ki te pūwāhi mura me te hāora (O₂) ka pāngia e te tauhohenga waikura kaha (tahu): 4Fe₂₂ → 2Fe2O, wera
• He nui te wera e tukuna ana e tēnei tauhohenga (tata ki te 3-5 ngā wā o te kaha o te taiaho tonu!), Koinei te kī ki te kaha "pūhui". Ka tino whakarei ake tēnei wera tāpiri i te kaha rewa/hau whānui.

3. Te tukanga mahi tahi whakakotahi:

• Te whakamahana me te whakakā: Ka whakamahana tuatahi te taiaho i te konganuku o te rohe ki te pūwāhi whakakā.
• Te tahunga wera-ā-waho: te werohanga hāora, ka mura kino te konganuku, ka puta he wera nui atu i te mea ka taea e te taiaho te whakarato, ka tere te rewa, ka waikura rānei te konganuku, ā, ka puta he para (ko te nuinga ko te Feo me te Fe3o4).
• Te pupuhi me te hanga: Ko tētahi atu mahi nui o te rere o te hau hāora pēhanga teitei ko te pupuhi i te waikura whakarewa rewa (para) i puta mai i te tauhohenga mai i te tuitui tapahi kia rite ki te "maripi hau" hei hanga i tētahi mata tapahi ma, maeneene hoki.

Tonu: Ka neke te hihi taiaho ki mua, ka whakamahana tonu i te wāhi hou, ā, ka whai te tauhohenga mura i te arotahi taiaho ki mua, ki raro hoki, ā, ka mutu ka uru ki roto i te mea mahi ka hanga he tapahi.

He pēhea te whai huatanga o tēnei huarahi "whakakotahi"? (Painga)

1. Te kaha ki te tapahi i ngā pereti matotoru:Mō te maitai waro (pērā i te maitai waro iti), ko te tapahi hāora taiaho te tikanga tino whai hua me te tere rawa atu mō te tapahi i ngā pereti reo me te matotoru (neke atu i te 6mm, tae atu ki te 30mm, matotoru ake rānei). Ko te tapahi rewa taiaho parakore (pērā i te hauota) me whakawhirinaki katoa ki te kaha taiaho hei rewa i te konganuku, ā, te āhua nei kāore i te rawaka te mata o te pereti matotoru.

2. Tere tapahi tere:Nā te tāpiri o te pūngao matū o te tauhohenga tahunga whakarewa, he nui ake te kaha katoa e whakaurua ana i tērā o te pūngao taiaho kotahi, nō reira he tere ake te tere tapahi i te tapahi rewa i raro i te mana kotahi.

3He iti noa iho ngā whakaritenga mana mō ngā taputapu:Hei tapahi i te maitai waro kotahi, ko te mana taiaho e hiahiatia ana mō te tapahi hāora taiaho ka iti iho i te mana o te tapahi rewa taiaho parakore, ka whakaiti i ngā utu taputapu me te whakapaunga pūngao.

4. Te kounga tapahi pai:Mō ngā pereti matotoru o te maitai waro, ka taea te whiwhi i tētahi mata tapahi he pai te poutū me te iti ake o te para (te āhua tino pai).

Ngā āhuatanga me ngā herenga o te tukanga

1. Te whiriwhiri rauemi:

• Mō ngā konganuku tauhohe: Ko te rauemi tono tino noa me te tino pai ko te maitai waro.

• Kāore e tika ana mō te kowiri tira, te konumohe, te parahi, me ētahi atu:
• Kowiri tira: ka hangaia e te chromium (Cr) me ētahi atu huānga he waikura rewa teitei (pērā i te Cr2O3), ka ārai i te haere tonu o te tauhohenga waikura, ā, he uaua ki te pupuhi atu i te para, ka hua ake he mata tapahi taratara me te iri kino o te para.
• Konumohe me te parahi: he teitei ake te ira rewa o ōna waikura (Al2O3,CuO) i tō te papa tonu, e kapi ana i te mata pērā i te anga mārō, e ārai ana i te haere tonu o te tauhohenga, ā, he teitei hoki te whakaata ki te taiaho.

2. Ngā āhuatanga o te mata tapahi:

• Nā te tauhohenga waikura, ka whai paparanga waikura te mata o te tapahi (he rite ki te maimoatanga kikorangi) ā, tera pea he paku taratara (ki te whakataurite ki te taha kanapa o te tapahi hauota).
• Tērā pea he iti noa te paru e iri ana i te raro, me whakaiti mā te arotau i ngā tawhā tukanga.

3. He nui ake te rohe e pāngia ana e te wera:Ka nui ake te wera i te tauhohenga waikura kaha, ka whānui ake te rohe e pāngia ana e te wera o te mea mahi i tērā o te rewa me te tapahi laser, ā, ka paku nui ake pea te rerekētanga wera whānui o te mea mahi.

Te whakataurite ki ētahi atu tukanga tapahi

VS. Te tapahi hauota taiaho parakore (te tapahi rewa):

• Tapahi hauota: mā te whakarewa i te konganuku mā te taiaho, ka pupuhihia te konganuku rewa ki te hauota pēhanga teitei. Kāore he tauhohenga waikura, he kanapa te wāhanga, kāore he paparanga waikura, engari he puhoi te tere, he nui te kai hau, ā, he nui te utu. He pai mō te kowiri tira, te konumohe, me ētahi atu, ā, kāore e pai mō te maitai waro matotoru.
• Te tapahi hāora: tāpirihia te tauhohenga waikura, tere tere, iti te utu, he pai mō te maitai waro, engari he paparanga waikura kei te wāhanga.

VS. Te tapahi mura tuku iho (te tapahi oxyacetylene):

• Mura tuku iho: mā te whakamahana i mua i te mura, ka tapahia te tahunga hāora parakore. He puhoi te whakamahana, he whānui te āputa, he iti te tika, ā, he nui te whakarerekētanga wera.
• Te tapahi hāora taiaho: me te tika o te taiaho pūngao-teitei, te whakamahana tere, he tino whaiti te tuitui tapahi (me te diameter o te ira taiaho), he tino tika, he iti
• Ko te pari katoa, ko te pānga wera iti, ko te whakahoutanga tapahi mura tuku iho, he putanga whakapai ake tino tika.

Whakarāpopototanga

Ko te kaupapa matua o te mīhini tapahi mura taiaho (hāora taiaho) ko te whakamahi i te hihi taiaho kaha-teitei hei whakakā tika me te pupuri i te tauhohenga mura o te konganuku (rino) i roto i te taiao hāora parakore, me te whakakotahi i te kaha wera o te taiaho me te kaha matū o te waikura konganuku hei whakatutuki i te pānga tapahi "1 1>2". Ka whakakotahi pai i ngā painga o te tino tika me te arotahi teitei o te taiaho me ngā painga o te tino whai hua me te iti o te utu o te mura hāora, ka waiho hei tukanga matua e kore e taea te whakakapi i roto i te mara o te tapahi pepa maitai waro waenga me te matotoru.
