Ko te para rino, te para para whakamutunga i puta mai i te whakarewa maitai, he nui ngā huānga rino kei roto. Nā te nui o te kiato me te matotoru o te papatipu, kāore e taea te rongonui me te whakamahi i roto i te umanga hanga. Kāore anō kia pai te whakahoki mai i ngā rauemi rino utu nui, ā, ka hua ake he nui o ngā para. Me hangarua te para rino me te whakamahi anō mā te tukanga wehenga aukume, me te whakatutuki i ngā whakaritenga o te taumata rino paura e hiahiatia ana e te rauemi kei roto te rino mō te whakarewa oumu pupuhi, kia taea ai te hangarua i te para rino. Ka taea te whakamahi pai ake i roto i te hanga.
I tēnei wā, he tikanga whaihua ake te whakamahi i tētahi tukanga wehenga aukume, ā, he mea nui kia whiriwhiria ngā taputapu e tika ana hei whakatutuki i te wehenga rino me te whakaora whai hua. Ka hurihia te para maitai kia puta ai tōna wehenga, kātahi ka tangohia te konganuku paura mā te wehenga aukume maroke hau, ka whiwhihia te konganuku whāngai, te kukū me ngā para, ā, ka tātarihia te taumata rino katoa kia whiwhi ai i ngā tawhā tukanga me ngā taputapu pai rawa atu. Whakaratohia he tautoko hangarau tika mō te whakaputanga tuturu.
Ngā āhuatanga o te para maitai
Ko te para rino he para para i hangaia mā te whakamahi i te raima konupūmā-teitei, te raima hohe me ētahi atu rauemi āwhina mō te horoi me te pupuhi hāora i roto i te tukanga hanga rino, nō reira he nui te waikura rino kei roto, ko te tikanga 20%-40%, ā, he nui ake te ihirangi FeO i te Fe2O3, ko te mea tuatahi ko te tikanga 15%-25%, ko te mea tuarua ko te 5%-15%, ā, e whakaatu ana ēnei i te ngoikore o te aukume.
Ngā taputapu whakamātautau
Ko ngā taputapu whakamātautau e whakamahi ana i te wehewehe aukume maroke hau FX0665 o te Kamupene Huate, e whakamahia ana mō te tīpakonga o mua o te aukumeiti i mua i te huri, te whakaputa rānei i te kukū matawhāiti mai i te aukumeiti paura.

anga o raro
Kei te whakaatuhia te kaupapa mahi o te wehewehe aukume paura maroke hau i roto i te pikitia. Ka whāngaihia ngā kohuke ki te mata o te pahu aukume mā te putanga whāngai o te pahu 3, ā, ka mimitihia ngā kohuke aukume ki te mata o te pahu aukume 4 i raro i te mahi a te kaha aukume, ka hurihuri tahi me te pahu aukume 4. I roto i tēnei tukanga, ka tukuna ngā kohuke i runga i te mata o te pahu aukume 4 ki te mahi tahi o te pao aukume o ngā pou aukume koki-takai nui me ngā pou aukume maha-pou, te taputapu whakaoho aukume, te taputapu whakauru hau 6 me te putanga tango puehu 5, kia tino whakakorea ai ngā poke o ngā kohuke me ngā rauropi rawakore e hono tahi ana. Nō reira, ka whakapaitia te taumata o te kukū. I muri i te hurihuri i ngā kohuke kua tīpakohia ki te wāhi kore-aukume me te pahu aukume 4, ka whakakīia ki roto i te putanga kukū 9 i raro i te mahi a te kaha ā-papa, te kaha whakatere me te taputapu tango hei kukū. Ka tangohia ngā kohuke kore-aukume, ngā tinana kikokore rānei e hono tahi ana mai i te waha o ngā parapara 8 i raro i te mahi a te kaha ā-papa me te kaha whakatere, ka huri hei parapara, hei konganuku waenga rānei.
Auahatanga me te hangarau matua o te wehenga aukume maroke hau paura
1. Ka whakamahia te whāngai wiri mō te whāngai, ā, ka taea te whakarite i ngā tawhā o te whāngai kia rite ai te whāngai;
2. Ka whakamahia e te pūnaha aukume he hoahoa maha-pou, he koki takai nui (tae atu ki te 200-260 nekehanga), he kaha mara teitei (3000-6000Gs), ā, ka taea te whakarerekē i te hanganga pūnaha aukume kia rite ki ngā āhuatanga kohuke hei whakatutuki i ngā tohu painga whaitake;
3. Ka whakarerekētia te tere raina o te rango i roto i te 1-20m/s, ā, ka taea te whiriwhiri i te tere raina tika kia rite ki te āhua o te konganuku; he mea hanga te rango ki te rauemi kore-whakarewa, ā, he taputapu whakaoho aukume hei whakapai ake i te taumata kukū;
4. He hanganga maripi hau motuhake, he taputapu utu hau me te taputapu tango puehu (ka taea te whiriwhiri i ngā tawhā e tika ana kia rite ki te āhua me ngā whakaritenga tohu o te konganuku); he taputapu tango i te mata o te rango, ka taea te whakatutuki i te tukunga ma o te kukū;
