He aha ka ʻokoʻa ma waena o ka bauxite maka a me ka bauxite kuke?

ʻO koʻu ʻāina kahi mea hana nui a me ka mea hoʻopuka i nā mea refractory, me ka hoʻopuka waiwai refractory no 65% o ka huina honua. ʻO Bauxite kekahi o nā mea waiwai nui no ka hana ʻana i nā mea refractory. ʻO ka Bauxite i loko o ka ʻoihana refractory e pili ana i ka ʻaila bauxite me kahi maʻiʻo Al2O3 calcined o ≥48% a me kahi haʻahaʻa haʻahaʻa Fe2O3. Ma ke ʻano he kumu waiwai nui no nā mea refractory, noho ka bauxite i kahi kūlana hiki ʻole ke hoʻololi.

ʻO ka ʻokoʻa nui ma waena o ka bauxite maka a me ka bauxite kuke ʻia nā ʻano mineral like ʻole: ʻo ka kaolinite a me ka diaspore ka mea maka, a ʻo ka clinker he mullite. ʻO ka bauxite clinker, i kapa ʻia he mea alumina kiʻekiʻe, nā ʻāpana alumina kiʻekiʻe i hana ʻia mai kāna clinker he mea refractory a anti-corrosion i hoʻohana nui ʻia i ka ʻoihana metallurgical a me nā ʻoihana ʻē aʻe, i hoʻohana nui ʻia ma luna o nā kapuahi uila, nā umu ahi a me nā umu wela wela. . He mea koʻikoʻi ka hopena refractory, a ʻoi aku ka maikaʻi o kāna hana ma mua o nā pōhaku lepo refractory maʻamau. Bauxite: he alumini oxide oka me ke kinikini Al2O3.H2O, Al2O3.3H2O a me ka FE2O3.SiO2. He melemele a ʻulaʻula no ka mea aia i loko o ka iron oxide, no laila ua kapa ʻia ʻo ia "iron vanadium soil". ʻO ia ka mea nui no ka hoʻoheheʻe alumini. Hoʻokaʻawale ʻia ʻo Bauxite i loko o ka metallurgical grade, chemical grade, refractory grade, grinding grade, cement grade, etc. e like me kona hoʻohana ʻana.

Hoʻohana ʻia no ka hana ʻana i nā mea refractory, kapa ʻia kēia ʻano bauxite i ka alumina papa refractory.

Hoʻohana ʻia ʻo Alumina clinker me nā ʻāpana kūpono o AL2O3/Fe2O3 a me AL2O3/SiO2 e hoʻoheheʻe i ka alumina·/Fe2O3 a me AL2O3/SiO2.

Hiki ke hana ʻia ka bauxite clinker i mau aggregates a hoʻohana ʻia e like me nā mea refractory e like me ke kila a me ka uku umu. 5. Hiki ke hana ia i loko o ka pauka maikaʻi no ka hoʻolei ʻana, nā pale pale refractory a me nā ʻoihana ʻē aʻe. Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i ka wai hoʻomaʻemaʻe wai polyaluminum ferric chloride.
