E hoʻomaopopo pono i ke kaʻina hana o ka pauka corundum ʻeleʻele
Ke kū nei i ʻekolu mika ka mamao mai ka umu ahi uila, ua pā mai ka nalu wela i wahī ʻia i ke ʻala o ka metala i puhi ʻia i kou maka - ke ʻōwili nei ka slurry bauxite ma luna o 2200 degere i loko o ka umu me nā pehu ʻulaʻula gula. Ua holoi ke kumu kahiko ʻo Lao Li i kona hou a ʻōlelo akula: "E ʻike ʻoe? Inā he lanahu hoʻokahi ʻōpae ka mea hana, e hāʻule ka mahana o ka umu i 30 degere, a ʻo kacorundum ʻeleʻele ʻo ka mea e puka mai ana e palupalu e like me nā biscuits." ʻO kēia ipu hao o ka "kila hoʻoheheʻe" e paila ana ka hiʻohiʻona mua o ka hānau ʻana o ka pauka corundum ʻeleʻele.
1. Hoʻoheheʻe ʻia: Ka hana paʻakikī o ka lawe ʻana i ka "jade" mai ke ahi
Ua kālai ʻia ka huaʻōlelo "fierce" i loko o nā iwi o ka corundum ʻeleʻele, a ua hoʻomaʻemaʻe ʻia kēia ʻano i loko o ka umu ʻālohilohi uila:
ʻO nā mea hoʻohui e like me ka lāʻau lapaʻau: kumu bauxite (Al₂O₃>85%), mea hoʻemi anthracite, a pono e kāpīpī ʻia nā waihona hao ma ke ʻano he "matchmaker" - me ka ʻole o ia mea e kōkua i ka hoʻoheheʻe ʻana, ʻaʻole hiki ke hoʻomaʻemaʻe ʻia nā silicates haumia. Ua pau nā puke hoʻohālikelike o nā hale hana kahiko ma ka moku ʻo Henan: "ʻO ka nui o ka lanahu ke ʻano o ke kalapona kiʻekiʻe a me ka ʻeleʻele, ʻoiai ʻo ka liʻiliʻi o ka hao ke ʻano o ka slag mānoanoa a me ka agglomeration"
ʻO ka mea huna o ka umu i hoʻokiʻekiʻe ʻia: Ua hoʻokiʻekiʻe ʻia ke kino o ka umu ma kahi kihi 15-degere e ʻae i ka heheʻe e stratify kūlohelohe, ʻo ka papa lalo o ka alumina maʻemaʻe e crystallizes i loko o ka corundum ʻeleʻele, a ʻo ka papa luna o ka ferrosilicon slag e ʻoki ʻia. Ua hoʻohana ka haku kahiko i kahi ʻoki lōʻihi e hou i ka puka laʻana, a ua hoʻomaʻalili ʻia nā kulu heheʻe i pīpī ʻia a ua ʻeleʻele ka ʻāpana kea: "Pololei kēia kala! Hōʻike ke kukui polū ua kiʻekiʻe ka titanium, a ʻo ke kukui hina ke ʻano ʻaʻole i wehe loa ʻia ka silicon"
ʻO ka hoʻomaʻalili wikiwiki e hoʻoholo i ka hopena: ninini ʻia ka mea heheʻe i loko o kahi lua hohonu a ninini ʻia me ka wai anuanu e "pahū" i mau ʻāpana, a hana ka mahu wai i kahi leo ʻūlū e like me ka popcorn. Hoʻopaʻa ka hoʻomaʻalili wikiwiki i nā hemahema lattice, a ʻo ka paʻakikī he 30% kiʻekiʻe ma mua o ka hoʻomaʻalili kūlohelohe - e like me ke kinai ʻana i ka pahi kaua, ʻo ke kī "wikiwiki"
2. Ke kuʻi ʻana a me ke ʻano: ke akamai o ke ʻano o nā "kāne paʻakikī"
ʻO ka paʻakikī o ka poloka corundum ʻeleʻele i waho o ka umu ua kokoke ia i kodaimanaHe nui ka pilikia e hoʻolilo iā ia i "koa elite" pae micron:
ʻO ka wehe ʻana o ka mīkini wili jaw
ʻO ka papa ʻauwae hydraulic e "crunches" a ua wāwahi ʻia ka poloka nui o ka basketball i nā walnuts. Kuhikuhi ʻo Operator Xiao Zhang i ka pale a hoʻopiʻi: "I ka manawa hope loa i hui pū ʻia ai kahi brick refractory, a ua haki ka papa ʻauwae i kahi hakahaka. Ua alualu ka hui mālama iaʻu a ua hoʻohewa iaʻu no ʻekolu lā"
ʻO ka hoʻololi ʻana i loko o ka wili pōpō
Ua halulu ka wili kinipōpō i hoʻopaʻa ʻia me nā granite, a ua kuʻi nā pōpō kila i nā poloka e like me nā mea hula ikaika. Ma hope o 24 mau hola o ka wili mau ʻana, ua puka mai ka pauka ʻeleʻele ʻeleʻele mai loko mai o ka puka hoʻokuʻu. "Aia kahi hana maʻalea ma ʻaneʻi," i kīkēkē ai ke loea i ka papa hoʻomalu: "Inā ʻoi aku ka wikiwiki ma mua o 35 rpm, e wili ʻia nā ʻāpana i mau nila; inā emi ma lalo o 28 rpm, e ʻoi loa nā kihi."
ʻO ke ʻoki kino plastik ʻo Barmac
Hōʻike ka laina hana kiʻekiʻe i kāna kāleka lanakila - ʻo Barmac vertical shaft impact crusher. Kuʻi ʻia ka mea e ke kuʻi ponoʻī ma lalo o ka hoʻokele o ka rotor wikiwiki, a ʻo ka pauka micro i hana ʻia he poepoe e like me nā ʻiliʻili muliwai. Ua ana ʻia kahi hale hana huila wili ma Zhejiang Province: no ka kikoʻī like o ka pauka micro, ʻo ke ʻano kuʻuna he 1.75g/cm³ ka nui o ka nui, ʻoiai ʻo ke ʻano Barmac he 1.92g/cm³ ka nui! Ua wili ʻo Mr. Li i ka laʻana a kaniʻuhū: "I ka wā ma mua, ua hoʻopiʻi mau ka hale hana huila wili e pili ana i ka wai maikaʻi ʻole o ka pauka, akā i kēia manawa ke hoʻopiʻi nei ʻo ia he wikiwiki loa ka wikiwiki o ka hoʻopiha ʻana e mālama."
3. Ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana: ka hahai holoholona pololei ma ke ao o nā microns
ʻO ka hoʻokaʻawale ʻana i nā ʻāpana 1/10 o ka mānoanoa o ka lauoho i nā papa like ʻole he kaua o ka ʻuhane o ke kaʻina hana:
ʻO ka mea pohihihi o ka hoʻokaʻawale ʻana o ke kahe ʻana o ka ea
Holo wikiwiki ka ea i hoʻopaʻa ʻia he 0.7MPa i loko o ke keʻena hoʻokaʻawale me ka pauka, a ʻo ka wikiwiki o ka impeller e hoʻoholo i ka "laina komo": 8000 rpm e pale ana iā W40 (40μm), a 12000 rpm e kāohi iā W10 (10μm). "ʻO wau ka mea makaʻu loa i ka nui o ka makū," kuhikuhi ka luna o ka hale hana i ka hale kiaʻi dehumidification: "I ka mahina i hala, ua hoʻokahe ka condenser i ka fluorine, a ua hui pū ka pauka micro a ālai i ka pipeline. Ua lawe ʻia ʻekolu mau hoʻololi e hoʻomaʻemaʻe iā ia."
ʻO ka pahi mālie o ka hoʻokaʻawale hydraulic
No nā pauka ultrafine ma lalo o W5, lilo ke kahe wai i mea hoʻokaʻawale. Hāpai ka wai maʻemaʻe i loko o ka bākeke hoʻokaʻawale i ka pauka maikaʻi ma ka wikiwiki o ke kahe ʻana o 0.5m/s, a hoʻopaʻa mua nā ʻāpana coarse. Nānā ka mea hana i ka mika turbidity: "Inā ʻoi aku ka wikiwiki o ke kahe ʻana o 0.1m/s, e pakele ka hapalua o ka pauka W3; inā lohi ʻo 0.1m/s, e hui pū ʻo W10 a hoʻopilikia."
ʻO ke kaua huna o ka hoʻokaʻawale magnetic a me ka wehe ʻana i ka hao
Lawe aku ka wili makeneka ikaika i nā ʻōpala hao me ka ikaika omo o 12,000 gauss, akā ʻaʻohe ona kōkua i nā kiko hao oxide. ʻO ka hana a ka hale hana Shandong: e hoʻomohu mua me ka waikawa oxalic ma mua o ka pickling, e hoʻololi i ka Fe₂O₃ paʻakikī i loko o ka ferrous oxalate hiki ke hoʻoheheʻe ʻia, a hāʻule ka nui o ka hao haumia mai 0.8% a i 0.15%.
4. Pʻūlū a me ke kala ʻana: ka "hānau hou" o nā abrasives
Inā ʻoe makemakepauka corundum ʻeleʻelei mea e kū ai i ka hoʻāʻo ʻana ma ka huila wili wela kiʻekiʻe, pono ʻoe e hala i ʻelua mau hoʻāʻo ola a me ka make:
ʻO nā dialectics waikawa-kumu o ka pickling
Piʻi aʻe nā pehu i loko o ka pahu waikawa hydrochloric e hoʻoheheʻe i nā mea haumia metala, a ʻo ka kaohi ʻana i ka nui e like me ka hele ʻana ma luna o ke kaula paʻa: ʻaʻole hiki i ka emi ma mua o 15% ke hoʻomaʻemaʻe i ka ʻōpala, a ʻoi aku ma mua o 22% e hōʻino i ke kino alumina. Ua paʻa ʻo Lao Li i kahi pepa hoʻāʻo PH e hāʻawi i ka ʻike: "I ka wā e hoʻopau ai me ka holoi alkaline, pono ʻoe e ʻomi pololei iā PH = 7.5. E hana ka waikawa i nā burrs ma nā kristal, a e hana ka alkaline i ka ʻili o nā ʻāpana i pauka."
ʻO ka puʻupuʻu mahana o ka calcination
Ma hope o ke kala ʻana ma 1450℃/6 mau hola i loko o kahi umu wili, e palaho nā mea haumia ilmenite i loko o ka pae rutile, a piʻi aʻe ke kūpaʻa wela o ka micropowder ma 300℃. Eia naʻe, ma muli o ka ʻelemakule ʻana o ka thermocouple o kekahi hale hana, ua ʻoi aku ka mahana maoli ma mua o 1550℃, a ua hoʻoheheʻe ʻia nā micro pauka a pau i puka mai loko mai o ka umu i loko o nā "keke sesame" - ua hoʻolei pololei ʻia he 30 tone o nā mea, a ua kaumaha loa ka luna o ka hale hana a hehi ihola kona mau wāwae.
Hopena: Nā aesthetics ʻoihana ma waena o nā millimeters
I loko o ka hale hana napoʻo, ke uwē mau nei nā mīkini. Ua holoi ʻo Lao Li i ka lepo ma luna o kona mau lole hana a ʻōlelo ʻo ia: "Ma hope o ka hana ʻana ma kēia ʻoihana no 30 mau makahiki, ua maopopo iaʻu ʻo nā pauka liʻiliʻi maikaʻi he '70% hoʻomaʻemaʻe a me 30% ola' - ʻo nā mea hoʻohui ke kumu, pili ka kuʻi ʻana i ka hoʻomaopopo ʻana, a pili ka māka ʻana i ka akahele." Mai ka bauxite a i nā pauka liʻiliʻi nano-scale, pili mau nā holomua ʻenehana i ʻekolu mau kikowaena: ka maʻemaʻe (pickling a me ka wehe ʻana i ka haumia), ke ʻano (Barmac shaping), a me ka nui o ka ʻāpana (precise grading).
