Mea hana refractory kiʻekiʻe kiʻekiʻe sandblasting castable keʻokeʻo corundum one pauda maikaʻi

Mea hoohuoi

manaʻo:
He papa o nā mea metala ʻole me ka refractoriness ʻaʻole i emi ma lalo o 1580°C.Hōʻike ka Refractoriness i ka mahana Celsius kahi e kūʻē ai ka hāpana cone refractory i ka hana o ka wela kiʻekiʻe me ka palupalu ʻole a me ka hoʻoheheʻe ʻana ma lalo o ke ʻano o ka ukana ʻole.Eia naʻe, ʻaʻole hiki i ka wehewehe ʻana o ka refractoriness ke wehewehe piha i nā mea refractory, a ʻo 1580 ° C ʻaʻole paʻa.I kēia manawa ua wehewehe ʻia ʻo ia nā mea a pau nona nā waiwai kino a me nā mea kemika e ʻae ʻia e hoʻohana ʻia i kahi ʻano wela kiʻekiʻe i kapa ʻia nā mea refractory.Hoʻohana nui ʻia nā mea refractory i ka metallurgy, ka ʻoihana kemika, ka ʻaila, ka mīkini hana, ka silicate, ka mana a me nā ʻoihana ʻoihana ʻē aʻe.ʻO lākou ka mea nui loa i ka ʻoihana metallurgical, e helu ana no 50% a 60% o ka huina.

hopena:
Hoʻohana ʻia nā mea refractory i nā ʻano like ʻole o ka ʻoihana aupuni e like me ke kila, nā metala non-ferrous, aniani, sima, seramika, petrochemical, mīkini, boilers, ʻoihana māmā, mana uila, ʻoihana koa, etc. hōʻoia i ka hana hana a me ka hoʻomohala ʻenehana o nā ʻoihana i luna.He hana koʻikoʻi a hiki ʻole ke hoʻololi ʻia i ka hoʻomohala ʻana i ka hana ʻenehana kiʻekiʻe.
Mai ka makahiki 2001, i alakaʻi ʻia e ka hoʻomohala wikiwiki ʻana o nā ʻoihana wela kiʻekiʻe e like me ka hao a me ke kila, nā metala nonferrous, petrochemicals, a me nā mea kūkulu hale, ua mālama ka ʻoihana refractory i kahi ulu ulu maikaʻi a lilo i mea hana nui a me ka mea kūʻai aku i nā mea refractory i ka honua.I ka makahiki 2011, ua helu ʻia ka hana refractory o Kina ma kahi o 65% o ka huina o ka honua, a ʻo kāna hana a me kāna kūʻai kūʻai ʻana i hoʻonohonoho mua ʻia ma ka honua.
ʻO ka hoʻomohala ʻana o ka ʻoihana refractory e pili kokoke ana i ka mālama ʻana i nā kumu waiwai mineral home.ʻO ka Bauxite, ka magnesite a me ka graphite nā mea refractory nui ʻekolu.ʻO Kina kekahi o nā mea kūʻai nui loa ʻekolu o ka honua i ka bauxite, nā waihona magnesite nui loa o ka honua, a me ka mea lawe nui i ka graphite.Ua kākoʻo nā kumuwaiwai waiwai i nā mea refractory o Kina no nā makahiki he ʻumi o ka hoʻomohala wikiwiki.
Me ka manawa "Umikūmālua ʻElima Makahiki", ke wikiwiki nei ʻo Kina i ka hoʻopau ʻana i ka mana o ka wā kahiko a me ka nui o ka ikehu.E kālele ana ka ʻoihana i ka hoʻomohala ʻana a me ka hoʻolaha ʻana i nā kapuahi hoʻōla ikehu hou, ka hoʻomohala ʻana i nā ʻenehana hoʻōla ikehu piha, ka mālama ʻana i ka ikehu, ka mana hoʻokuʻu ʻana o nā "ʻekolu ʻōpala" a me ka hoʻohana ʻana i nā kumuwaiwai o nā "ʻekolu ʻōpala" Recycling, etc. ka hoʻohana hou ʻana o nā kumuwaiwai a me ka hoʻohana hou ʻana i nā mea refractory ma hope o ka hoʻohana ʻana, e hōʻemi i ka hoʻokuʻu ʻana i nā ʻōpala paʻa, hoʻomaikaʻi i ka hoʻohana piha ʻana i nā kumuwaiwai, a hoʻoikaika nui i ka mālama ʻana i ka ikehu a me ka hoʻemi ʻana i ka hoʻokuʻu.
Hōʻike ka "Refractory Industry Development Policy" i ka hoʻohana ʻana o nā mea refractory i loko o ka ʻoihana kila o Kina ma kahi o 25 kilokani no ke ton o ke kila, a e hāʻule ia ma lalo o 15 kilokani ma 2020. I ka makahiki 2020, e lōʻihi ke ola o nā huahana refractory o Kina. , ʻoi aku ka ikaika o ka ikehu, pollution-free, a me ka hana.E hoʻokō nā huahana i nā pono o ka hoʻomohala ʻana i ka ʻāina e like me ka metallurgy, nā mea kūkulu hale, nā kemika, a me nā ʻoihana e kū mai ana, a e hoʻonui i ka ʻike loea o nā huahana i waho.

He nui nā ʻano mea refractory a me nā hoʻohana like ʻole.Pono e hoʻokaʻawale ʻepekema i nā mea refractory e hoʻomaʻamaʻa i ka noiʻi ʻepekema, koho kūpono a me ka hoʻokele.Nui nā ʻano hoʻokaʻawale no nā mea refractory, me ka hoʻokaʻawale ʻana i ke ʻano kemika, ka hoʻokaʻawale ʻana o ka mineral chemical, ka hoʻokaʻawale ʻana i ke kaʻina hana, a me ka hoʻohālikelike ʻana i ka morphology material.

Hoʻokaʻawale:
1.According i ka pae o refractoriness:
ʻO nā mea hoʻomaʻamaʻa maʻamau: 1580 ℃ ~ 1770 ℃, mea hana refractory kiʻekiʻe: 1770 ℃ ~ 2000 ℃, mea hana refractory papa kūikawā: >2000 ℃
2. Hiki ke hoʻokaʻawale ʻia nā mea refractory i:
ʻO nā huahana i puhi ʻia, nā huahana i puhi ʻole ʻia, nā refractory ʻole
3. Hoʻokaʻawale ʻia e nā waiwai kemika:
ʻAkika refractory, neutral refractory, alkaline refractory
4. Hoʻokaʻawale ʻia e like me ka hui ʻana o ka mineral kemika
Hiki i kēia ʻano hoʻohālikelike ke kuhikuhi pololei i ka haku mele a me nā ʻano o nā mea refractory like ʻole.He ʻano papa helu maʻamau i ka hana ʻana, hoʻohana, a me ka noiʻi ʻepekema, a he koʻikoʻi koʻikoʻi no ka hoʻohana ʻana.
Silica (silica), alumini silicate, corundum, magnesia, magnesia calcium, aluminika magnesia, magnesia silika, carbon composite refractory, zirconium refractory, special refractory
6. Hoʻokaʻawale ʻana i nā mea refractory unshaped (i hoʻokaʻawale ʻia e like me ke ʻano o ka hoʻohana ʻana)
ʻO nā mea hoʻoheheʻe, nā mea hoʻoheheʻe ʻia, nā mea ramming, nā plastik, nā mea paʻa, nā mea projection, nā mea hamo, nā mea haʻalulu maloʻo, nā mea hoʻoheheʻe ponoʻī, nā slurries refractory.
Hoʻokumu ʻia nā refractory neutral me ka alumina, chromium oxide a i ʻole carbon.ʻO ka huahana corundum i loaʻa ma mua o 95% alumina he mea refractory kiʻekiʻe kiʻekiʻe me kahi ākea o ka hoʻohana.
ʻO Chiping Wanyu Industry a me Trade Co., Ltd., i hoʻokumu ʻia i ka makahiki 2010, he loea i ka hana ʻana i nā huahana aahu a me ka refractory: keʻokeʻo corundum ʻāpana one, pauka maikaʻi, a me nā huahana moʻo ʻeleʻele.
ʻO nā kikoʻī kikoʻī o ka moʻo ʻaʻahu: 8-5#, 5-3#, 3-1#, 3-6#, 1-0#, 100-0#, 200-0#, 325-0#
Nā kikoʻī o ke one one: 20#, 24#, 36#, 40#, 46#, 54#, 60#, 80#, 100#, 150#, 180#, 200#, 220#, 240#,
