Pehea e ʻike ai i ka maikaʻi o ka pauka ferrochrome kalapona kiʻekiʻe

Nā koi no ka chromium ore: haku mele: Cr2O3 ≥ 38, Cr/Fe>2.2, P<0.08, C maʻiʻo ʻaʻole iʻoi aku ma mua o 0.2, ʻoi aku ka nui o ka wai ma mua o 18-22%, etc.; Pono ke kūlana kino i hikiʻole i ka hao hao ke komo i loko o nā haumia, nā papa lepo a me nā mea'ē aʻe. He 5-60mm ka puunaue nui o kekahi apana chrome ore, a o ka nui malalo o 5mm aole e oi aku mamua o 20% o ka huina waiwai.

ʻO nā koi no ka coke: nā mea i haku ʻia: paʻa mau kalapona>83%, lehu<16%, mea volatile i ka waena o 1.5-2.5%, ka nui o ka sulfur ʻaʻole iʻoi aku ma mua o 0.6%, ʻaʻole iʻoi aku ka nui o ka wai ma mua o 10%, P2O6 ʻaʻole iʻoi aku ma mua o 0.04%; Pono ke kūlana kino i ka nui o ka puʻupuʻu coke ʻo 20-40mm, a ʻaʻole ʻae ʻia nā mea maka i loko o ka ʻoihana metallurgical e nui a haki paha, ʻaʻole hiki ke komo i loko o ka papa lepo, sediment a me ka pauka.

ʻO ka pauka kalapona ferrochrome kiʻekiʻe me ka maikaʻi maikaʻi e hoʻomaikaʻi i ke kūpaʻa ʻaʻahu a me ka paʻakikī o nā huahana stainless steel, ʻoiai ke kiʻekiʻe carbon ferrochrome pauka a mākou e hāʻawi nei he maikaʻi maikaʻi a ʻo kā mākou ʻano hoʻolaʻa e hiki ai i nā mea kūʻai ke hoʻohana me ka hilinaʻi ma hope o ke kūʻai ʻana.
