1. Te āhua o nāianei o te whakamahinga rauemi o te para maitai:

Kua roa te whakaurunga o te paura para rino ki roto i te paerewa ā-motu hei ranunga sima. He maha ngā whakamātautau whakatairite kua whakaatu: Ina neke atu i te 420m2/kg te horahanga mata motuhake o te paura para rino, he rite tonu tōna mahi ki te para oumu pupuhi. Mā te whakaranu i te paura para rino me te paura para, kāore e taea anake te whakapai ake i te ōwehenga o te paura para rino i roto i te paura hiato, engari ka whakanui ake hoki i te nui o te whakakapinga o te paura hiato ki te sima i runga i te whakarite i te mahi a te raima, kia whakaitihia ai te utu whakarite o te raima. Mārama noa ka taea te whakaiti i te whakarerekētanga o te here me te whakapai ake i te ātete pakaru o te here. E tohu ana tēnei he pai te tirohanga mākete mō ngā hua paura para rino. I tēnei wā, kua heke te pumau o te rōrahi o te para rino nā te noho o te CaO me te MgO kore utu. Ko te nui ake o te waikura rino ka whakanui ake i te uaua o te huri, te nui ake o te paura para tana, me te uaua o te tukatuka i te paura para rino. Nō reira, he iti te rahinga hoko o te mākete paura para maitai, ā, nā tēnei anō hoki i huri ai te paura para maitai hei mākete putaiao hei whakawhanake.

2. mā te whakaranu raima ka wātea te wāhi mō te whakamahi i te huri para maitai tino pai:

He panoni nui te whakaranu pokapū raima i roto i te momo whakaputa o ngā kaupapa hanga, ā, ko te ōwehenga o ngā tono raima kua oti te whakaranu te tohu i te taumata o te whakaputanga ahumahi raima i roto i te whenua. E whakaatu ana ngā mahi ka taea e te whakamahinga o te raima kua oti te whakaranu te whakanui ake i te hua o te mahi neke atu i te rua, te penapena sima 10% ~ 15%, te whakaiti i ngā utu kaupapa tata ki te 5%, ā, ka taea te whakarite i te kounga o te kaupapa, te penapena whenua hanga, te whakaiti i te parahanga puehu, kia tutuki ai te hanganga matomato. Mā te whanaketanga o te raima arumoni ka whakatairanga i te whanaketanga o te whakaputanga paura para, ā, ka whakawhānui ake i te mākete tono mō te paura para. I whakatūria te wheketere whakaranu raima kua oti te whakaranu o Haina i te tekau tau atu i 1980, i te tīmatanga i Shanghai, Jiangsu me ētahi atu wāhi, nā te whānui haere tonu o te tauine hanga, inā koa nā te tere o te whanaketanga o te hanganga o ngā tāone takutai tonga-mā-rāwhiti, me te raupapa o ngā kaupapa here tautoko me ngā mahi i mahia e ngā mana whakahaere hanga, kia piki ake ai te raima kua oti te whakaranu o te tāone mā te 15% ia tau. Nā te mea he iti iho te utu o te para me te para maitai i te sima, he iti ake te utu o te konukura me te para maitai, ā, he pai hoki mō te whakamahi i roto i te konukura arumoni kua whakaranua kia kaha. Ko te konukura i hangaia mā te whakaranu i te para me te para maitai ki te sima, te kōhatu me te onepū kōwhai he kaha teitei, he iti te wera wai, he pai te ātete ki te kakahu me te kaha here nui ki ngā pae maitai. He tino pai mō ngā whare teitei, ngā pā, ngā taunga rererangi, ngā turanga hohonu nui me ngā kaupapa raro wai. I tēnei wā, ko te konukura kaha-tino ka whakaritea mā te whakaranu i te pungarehu silica me te kaihoko whakaiti wai tino pai, engari he nui te utu o te korenga o ngā rauemi mata pungarehu silica me te kaihoko whakaiti wai tino pai, ka hua ake he utu nui o te konukura. I te mea kua piki haere ngā whakaritenga mō ngā āhuatanga konukura i roto i ngā kaupapa motuhake nui, kua hua ake te hiahia nui mō te konukura arumoni i tētahi mākete whānui mō te whakamahinga whānui o te para me te paura para maitai. Kei te hohonu haere hoki te māramatanga o te tangata ki ngā āhuatanga o te para me te paura para maitai, he rauemi hanga hou. I te whakatairanga me te whakamahinga o te raima arumoni i roto i te whenua me te whakatinanatanga o ngā paerewa ā-motu e pā ana ki ngā hua para me te paura para maitai, me te whakatinanatanga o ngā kaupapa here pēnei i te aukati kaha i te whakaranu i te raima i ngā papa hangahanga i ngā tāone nui, ka nui haere te mākete o te para me te paura para maitai, ā, ka nui haere te aro ki tōna whakamahinga.

3. kua rongonuihia, kua whakamahia hoki te tukanga whakarite me ngā taputapu o te huri poutū moroiti-paura para maitai

I tēnei wā, e whakamahia ana te hangarau huri poutū hei huri i te para rino paura iti, hei whakaputa hua hei whakakapi i te clinker sima kaha-teitei, e pā ana ki te hangarau whakaputa matatau i roto i te umanga. I mua, ko te para, te para rino me te clinker sima, te gypsum, me ētahi atu, e ai ki tētahi ōwehenga o te huri ki roto i te whakaputanga huri o te sima. Nā te ngoikore o te kaha o te para me te para rino, kāore e taea te huri i te huri kia tino pai ina konatunatua ki te clinker sima, kāore e taea te whakawhanake katoa i tana mahi, ā, ko te nui me te whakamahinga o te para me te para rino he iti noa iho ki tētahi whānuitanga. I roto i te whakarite i te paura tino pai mai i te para rino anake, kei mua ngā umanga rino me te rino o Jiangsu. He maha ngā umanga rino e tohuhia ana e Changzhou Zhongtian Iron and Steel kua hanga i ngā raina whakaputa tukanga huri poutū motuhake mō te para rino. Hei kaihanga mira poutū para rino paura iti, ka whakarato a HCM Machinery i te tautoko hangarau i roto i te huarahi tukanga huri para rino tino pai me te hanga taputapu mira poutū matua. Ko ōna āhuatanga hangarau ko ngā āhuatanga e whai ake nei: te whiriwhiri i te paura para maitai huri mira poutū, me te hangarau matatau, te whakaputa pono, ngā āhuatanga hua mahi teitei, me te mira poutū hei whakaputa i te tana o te horahanga mata motuhake o te 400m2/kg ~ 500m2/kg para, te paura para maitai, i te whakaputa mira pōro tuku iho o te taumaha paura kotahi e penapena ana i te hiko 30% ~ 50%; Ka konatunatua tika te paura pai o te para me te para maitai ki te raima, ka penapena i te nui o te sima, ā, ka penapena i te whakapaunga pūngao o te whakaputa sima. Ka taea e te para, te tukanga huri para maitai, te whakarerekē ngāwari i te pai o ngā hua kia rite ki ngā hiahia o te mākete. Mā te pikinga o te tāpiri o te para me te para maitai ki te raima, ka taea te whakaiti i te wera makuku me te ihirangi o ngā wāhanga kino o te raima, ka hangaia he āhuatanga pai mō te whakapai ake i te mahi a te raima me te iti o te whakapaunga pūngao. Ka hurihia te para maitai e te paura huri poutū, ā, ka hurihia te rauemi i roto i te taiao makuku i te pāmahana teitei (100℃ ~ 300℃). Ko te nuinga o te konupūmā waikura kore utu me te konupūmā waikura kore utu i roto i te paura iti o te para maitai ka whakamakukuhia hei konupūmā waikura kaha me te konupūmā waikura. Hei tāpiri, nā te whakaurunga o te para me te para maitai ki roto i te raima, ka taea te whakaiti i te tauhohenga o te konganuku kawakore, ka taea te ārai i ngā kapiti iti o te raima, ā, ka taea te whakaroa i te roa o te ora o ngā whare. Nō reira, e maioha ana te umanga hanga ki te konupūmā i konatunatua ki te paura para mō ōna āhuatanga ahurei. Ka taea te whakamahi i te para maitai huri anake hei hua mō te hanga raima me te whakaranu kia rite ki ngā hiahia o te mākete, ā, ka taea hoki te whakarerekē kia rite ki te hiahia ki te whakarerekē i te pai me te nui o te whakaranu hei whirihora ki te sima hei hoko.
