Te Whakarewa i te Umu Whakaoho me nga Whakaoho

Ko te oumu pupuhi he taputapu ngingiha tuku iho hei whakamahana i te whakarewa, i etahi atu matū ranei. Ko tana kaupapa matua ko te whakarato i te kaha o te wera wera nui ma te whakarato i te hau nui ki te ruuma mura kia kaha ake te mura o te mura.. Ko nga oumu pupuhi e whakamahia nuitia ana i roto i nga mahi whakarewa parahi, arahi, mata-konutea, antimoni, me etahi atu konganuku.

Te hanganga o te oumu pupuhi

Ko te oumu pupuhi he tuanui o te oumu, tinana oumu, moenga matua (ka kiia hoki ko te korokoro), ahi ahi, taputapu pupuha, me etahi atu.

Te runga oumu

Ko te tuanui te waahanga o runga o te oumu pupuhi, e mohiotia ana ko te tuanui. He hanganga hiri e whakamahia ana hei hipoki i te tihi o te tinana o te oumu ki te pupuri i nga wera nui i roto i te oumu me te whakahaere pai i te tukanga ngingiha.. He raupapa o nga tauranga oumu, tauranga utu ranei ka whakaritea ki runga i te tuanui o te oumu mo te whangai me te tuku hua ki roto i te oumu..

Anga oumu

Ko te rakau oumu te hanganga porotakaroa matua o te oumu pupuhi, ko te ipu mo te utu me te wahie, ka noho ki te mahi whakarewa. I te nuinga o te wa ka hangaia te tinana o te oumu ki nga pereki whakaraerae, ki nga taonga whakaahuru ranei kia mau tonu ai te hanganga i nga pāmahana teitei.. I te nuinga o te waa he putanga para i raro o te tinana oumu hei tuku i te para para i hangaia i roto i te oumu..

Te taumata Tuyere, te rewharewha ranei

The bed is the conical lower area of the blast furnace, also known as the hearth. During the smelting process, ore, coke, and other fuels are put into the bed through the furnace roof. In this bed, the smelting reactions start to take place and the resulting hot gases and liquid metal rise to the upper area of the furnace shaft.

Blast furnace hearth

The hearth is another common name for the bed, which is the area directly related to the smelting reaction in the blast furnace. In the hearth, the high-temperature gas produced by coke combustion reacts with the iron ore, reducing the iron ore to liquid iron, while the waste slag forms scum and floats on the surface of the molten iron.

Tuyere System

The tuyere device is an important part of the blast furnace. Ka whakamahia hei whakauru i te hau pehanga teitei (te nuinga o te rangi oumu) ki raro o te oumu ki te whakahaere me te pupuri i te tuku hāora e hiahiatia ana mo te tauhohenga whakarewa i roto i tenei moenga. I te nuinga o te waa he maha nga tuyere ka tohatoha huri noa i te paenga o te oumu pupuhi, e honoa ana ki nga paoho teitei me te mahi ngongo. Ma te whakatikatika i te tuunga o te tuyere me te rere o te hau, ka taea e te kaiwhakahaere te whakahaere tika i te pāmahana me te tukanga tauhohenga i roto i te oumu.

Te mahi o te oumu pupuhi?

Ko nga mea pakari penei i te utu whakarewa (arotahi, te ore i pania, etc.), coke, rewharewha, ka taapirihia nga mea whakamuri mai i te tihi o te oumu, me te hau pehanga teitei e pupuhihia ana ki roto i te taputapu tuyere i te taha o raro o te tinana oumu kei te haere ki runga., me nga mea whakararo ka pa ki nga tauhohenga penei i te whakarewa, hāoratanga, me te whakaheke hei whakaoti i te mahi whakarewa. Te whakarewa wai, hāmārie, ka puta mai te para i te korokoro, i te ahi ranei i te taha o raro o te oumu, me te hau rewharewha, puehu paowa, konganuku hau, ka tukuna ranei nga waikura whakarewa mai i te putanga hau rewharewha i runga o te oumu.

Ko ehea nga rauemi e whakamahia ana i roto i nga oumu pupuhi?

I tenei wa, te nuinga o ratou he tuanui oumu kati, me te tinana oumu he koti wai ki tonu. Ka whakamahia noa nga mea whakamaarama ki te korokoro me te ngakau, no te mea he para kawakore te para, no reira ko te nuinga o te korokoro he pereki magnesia, pereki magnesia-chrome, me nga pereki konumohe-chrome; Ko te waahanga o runga he mea hanga pereki magnesia, pereki chrome magnesia, me nga pereki chrome konumohe; ka hangaia te raro o te oumu ki roto i te kikorangi whakamuri
