Me pēhea te ki te hanga i te raima whakangutungutu ki o ratou ringa?

maha e rapu Construction o ngā whakaurunga mō ngā take rerekē te whakamahi o ngā rauemi ahi-ātete. Ka taea te whakamahi ratou ki te tiaki i te iwi me ngā hanganga. Ka rite ki protrudes tetahi o taua rauemi raima whakangutungutu. E tonu ētahi o ona rerekē e taea o pangia te rongo ki pāmahana ki runga ki te 1000 ° C, me te āhua me ngā āhuatanga whai hua.

āhuatanga matua

I roto i te āhuatanga matua o taua raima kia miramira:

• refractoriness tiketike;
• āhuatanga mahi whakarei;
• kaha;
• kahore Me ki te whakamahi i tētahi tukanga puhipuhi utu i roto i te hanga.

Ki te rā, ka taea te whakarōpūtia raima whakangutungutu mea pauna. Hanga koe ranei e taea te whakaahuatia kia i nga momo e whai ake nei o te rauemi:

• ngā nui;
• ngāwari;
• mata;
• taimaha.

Ka rite ki te hua, e taea te whiwhi rauemi e taea te mahi i te mahi hanganga tuuraa ranei e tei runga i te hanganga o te whakauru.

āhuatanga ahumahi

Ki te mea kua whakaritea e koe ki te hanga raima whakangutungutu, kia waiho ai hei titiro i tona hanganga. Material mahi ana i runga i te pūtake o te wāhanga taketake, me te etahi tāpiritanga, i roto i nei ko:

• onepu Fireclay;
• magnesite;
• Rerekē momo o paru ;
• sima aluminous.

I roto i te tāpiritanga ki te kia tonu tohatoha mira whenua me ngā kohuke, e homai te kaha rauemi. I roto i taua tāpiritanga:

• pungapunga;
• miro hurihia ore chromite;
• hau para oumu.

E tapiritia ēnei wāhanga ki te whakapiki ake i te kiato o te hua oti e kore anake, engari ano hoki i te hanganga maroke. I te tahi taime, puriwāhi mō te hanga i hanga i raro i te tipu, engari kia whakamahia ai i roto i ētahi wā toka whakangutungutu ka pupuhi whawhai pereki whakangutungutu. Hoki ngā kōeke o te raima tapiritia māpele o wehenga rerekē. Ki te mea te reira te mea o te matotoru, kia whai i te mea timatanga i te diameter i roto i te whānuitanga 5 ki te 25 mm o. A, no te haere mai te reira ki whaina, he reira te rohe 0.15 me te 5 mm o. I roto i enei kai kia miramira:

• magnesite pereki;
• pereki fireclay;
• whawhai pereki noa;
• para aluminous;
• diabase;
• ōnewa;
• mauriora para hau oumu.

Ko te tino noa i roto i kiritaki ko te raima whakangutungutu, e te hangaia te whakamahi i te ahi paru, no te mea tutaki reira nga hiahia katoa o te hanganga. Nga kai aluminophosphate me mahi karaihe wai rite te takawaenga. Portland, Magnesite me tima aluminous , a ka mahi ka rite ki uwhi wāhanga. Ki te tapiritia te kai ki te karaihe wai, ka taea e te whakapai ake i te reira i te mahi. Ko te pono rawa tenei ki te whakamahia te ranunga raima ki te hanga i te apa te raima.

Hoki atu tohutohu i runga i te hangarau

raima whakangutungutu, te hanganga o nei whakaahuatia te i roto i te tuhinga, kia whai i te tetahi waitohu. titau ia momo te tua o tona plasticizer, puehu magnesite me ferrochromium para. Ki te whai koe i te whāinga ki te faaineine i raima ono tekau, kia koutou te whakamahi i te rauemi whänui o te momo:

• vermiculite;
• paru whakawhānui;
• Onemata.

Ki te whakatau koe ki te tono i te hanga o te ranunga i te ngaio, te ōwehenga o te wāhanga, ka kohia e ratou a ratou, i roto i runga i tou kaupapa. whiriwhiri te hanganga kei te rite ki te pāmahana, me te mahi tikanga whakahaere.

I tua atu, i te hanganga o te momo o te filler

Ki te whakatau koe ki te hanga i te raima whakangutungutu ki o ratou ringa, ka kua taea te whakamahi e koe rerekē taima, ara:

• dinas;
• corundum;
• kiripaka;
• hanumi rite.

Whakaaro i te hanganga raima, ngā te waitohu. Hei tauira, ASBG ko te ranunga maroke whakangutungutu konumohe-kei roto, whakamahia nei i roto i metallurgy ferrous me nonferrous me ngāwhā mana. raima High-alumina ki ngā āhuatanga whakangutungutu haapotohia VGBS me te tikanga ki te hanga i te ararewa nukurau kotahi o e maka ana koko, taiepa, me te raro o te pūrere.

kia whakamahia ai taua hanganga i pāmahana ki runga ki te 1800 ° C. Whakapakari ranunga maroke o tiketike-Saba whakaritea e te pukapuka. Ko te tikanga mo te wae waiariki, oumu, me te taputapu o te apa whakaū. Mārakerake ki te pāmahana e taea tae te taumata o 750 ° C.

Screed

Ka taea te kawea whakamaroke o te raima whakangutungutu i muri i te otinga o te taahiraa pakeke. I roto i tenei take e whakamahia rangi te me kore e te pāmahana ambient kia raro atu i +10 ° C. I mua e te raima whakawera tuatahi kia tiakina hoki te ra atu ranei ki te whakatutuki i te āhua on. mahi whakamaroke taea ki te whakaiti i te nui o te wai noa i roto i te raima, e e meinga he tauhohenga matū i waenganui i te huru, me te mata o te ararewa.

I muri te whakaora i te Ōseni mahue te i roto i te huru takawai kahore whakamaroke. I muri i haamărôraa he oti kia ararewa maroke. Ki te kore e taea tenei, mahue te raima kei roto i te taiao takawai kuiti. He mea nui ki te whakarite ventilation pai ranei waiho te Ōseni i roto i te wāhi pai-hā. Ki te kei te miharo koe pehea ki te hanga raima whakangutungutu, me waiho ratou waia ki te āhuatanga, me te ki te whakataka i te reira no te mahi. Hei tauira, kia tango i te taahiraa whakamaroke wahi te whakamahi i te mea powhiriwhiri tika pupuhi ranei, e ka tuku hau wera.

āhuatanga paraoa

I mua hanga i te raima whakangutungutu ki o ratou ringa, me te rawa āta whiriwhiri te hanganga o te otinga. I kī tenei i runga ake. Ko nga āhuatanga o te Mixing, ka e tūtohu ana ki te whakamahi i te hoe. he pai hoki raima wera-te tuuraa i, engari mo te rongoā totoka, me te i tika katoa reira, mai taea reira ki te uru kaupae me tika rauemi ki tua atu o iti wai. Ki te whakaaro ki te whakaranu sima, katahi ka waiho i te pānga tino uaua ki te whakatutuki i.

he hāngai hoki mo te take e, mo te mātotoru ihirangi makuku raima taea e tino tenei kupu. I muri i te katoa, mo nga rauemi whakaahuatia te hiahiatia te kaha mōrahi, me ki kiato tino pai. Na roto ratou natura, te tuuraa i raima he ngawari atu te pūrerehu, na ko reira nui e pokepokea ratou ki te nui e hiahiatia ana o te wai. Ka taea e tōna taikaha meinga he heke i roto i te kaha me te mātotoru, mea ka meinga te kore o te hekenga i roto i tukua.

Ko te ōwehenga o te raima whakangutungutu

kia whakahaere faaineineraa o te raima whakangutungutu i roto i te hanganga ture ki etahi ōwehenga. Ki te whakamahi i te rauemi whakaritea ki te whakaturia te ahi, ka muri solidifying te otinga e taea ki te tu atu pāmahana i roto i te whānuitanga 1200 ° C. kia Mai i te ranunga e taea te hanga kanga ahi me te firebox. Hoki te mahi ka hiahia te wahi raima 1 Tane-400, 2 ngā wāhanga onepu i pereki whakangutungutu, taua wahi o nga kongakonga whawhai pereki, me 0,33 wahi o te chamotte puehu tāpiri.

Ki te whakamahere koe ki te hanga i te pokapū totoka, ka ki runga ki a ia i roto i te mahi o te taputapu whakawera ka pā kia tūturu te mura tuwhera. Me whiwhi tēnei kia faaineine i te otinga ki te hanganga e whai ake nei: 2.5 wahi o kohatu i kurua, wahi raima, 0,33 wahi o chamotte onepu. Ka rite ki hoki rukerukenga, kia hanga ai o kiripaka pereki whero ranei, i ētahi wā ētahi wā whakamahia mira pereki whenua whero.

mutunga

Āhuatanga o te otinga mō te hanga i te raima whakangutungutu rite ki te hunga e whakamahia ana i roto i te tikanga Mixing sima slurry. Ki te ki te kia kawea te makona i ki te formwork, kia whakahaua te nekehanga tākaraka. I te tahi taime e whakamahia hua mō te hanga āhua i te kahupapa.

I roto i te tikanga ki te karo te whakaetonga o te wai i roto i solidification, me kia hiritia te pokepokea ai i muri i te hanga. whakahaere ana tēnei tango māmā o castings. Ko te huarahi māmā ki te hiritia - polyethylene, engari i roto i te tikanga ki te whakatutuki i te hua pai, kia koutou te whakamahi i silicone, i te mea lubricated-mua ki te hinu huawhenua.
