1. Ke kūlana o kēia manawa o ka hoʻohana ʻana i nā kumuwaiwai o ka slag kila:

Ua lōʻihi ka hoʻokomo ʻia ʻana o ka pauka slag kila i loko o ke kūlana aupuni ma ke ʻano he hui sima. Ua hōʻoia ka nui o nā hoʻāʻo hoʻohālikelike: Ke ʻoi aku ka nui o ka ʻili o ka pauka slag kila ma mua o 420m2/kg, ua like kāna hana me ka slag umu pahū. ʻO ka hui pū ʻana o ka pauka slag kila a me ka pauka slag ʻaʻole hiki ke hoʻomaikaʻi hou i ka hapa o ka pauka slag kila i loko o ka pauka hui, akā hoʻonui pū i ka nui o ka hoʻololi o ka pauka hui i ka sima ma ke kumu o ka hōʻoia ʻana i ka hana o ka sima, i mea e hōʻemi hou ai i ke kumukūʻai hoʻomākaukau o ka sima. Hiki iā ia ke hōʻemi i ka hoʻololi ʻana o ka shrinkage o ka mea hoʻopaʻa a hoʻomaikaʻi i ke kū'ē ʻana o ka mea hoʻopaʻa. Hōʻike kēia he manaʻolana maikaʻi ko nā huahana pauka slag kila. I kēia manawa, ua emi ka paʻa o ka nui o ka slag kila ma muli o ke ola ʻana o ka CaO manuahi a me MgO. ʻO ka nui o ka ʻike o ka hao oxide e hoʻonui ai i ka paʻakikī o ka wili ʻana, ka nui o ka hoʻohana ʻana i ka mana o ka pauka slag ton, a me ka paʻakikī o ka hana ʻana i ka pauka slag kila. No laila, he liʻiliʻi ka nui o ke kūʻai aku ʻana o ka mākeke pauka slag kila, ʻo ia hoʻi ka mea e lilo ai ka pauka slag kila i mākeke e kū mai ana e hoʻomohala ʻia.

2. hāʻawi ka hui ʻana o ka sima i kahi no ka hoʻohana ʻana i ka wili ʻana o ka slag kila ultrafine:

ʻO ka hoʻohuihui kikowaena ʻana o ka sima kahi hoʻololi nui i ke ʻano hana o nā papahana kūkulu, a ʻo ka hapa o nā noi sima i hui mua ʻia e hōʻailona ana i ka pae o ka hana ʻoihana sima ma ka ʻāina. Hōʻike ka hana maʻamau e hiki i ka hoʻohana ʻana i ka sima i hui mua ʻia ke hoʻonui i ka huahana hana ma mua o ka pālua, mālama i ka sima 10% ~ 15%, hōʻemi i nā kumukūʻai papahana ma kahi o 5%, a hiki ke hōʻoia i ka maikaʻi o ka papahana, mālama i ka ʻāina kūkulu, hōʻemi i ka haumia lepo, i mea e hoʻokō ai i ke kūkulu ʻōmaʻomaʻo. ʻO ka hoʻomohala ʻana i ka sima kalepa e paipai i ka hoʻomohala ʻana o ka hana pauka slag a hoʻonui i ka mākeke koi o ka pauka slag. Ua hoʻokumu ʻia ka hale hana hoʻohuihui sima i hui mua ʻia o Kina i nā makahiki 1980, i hoʻomaka ma Shanghai, Jiangsu a me nā wahi ʻē aʻe, ma muli o ka hoʻonui mau ʻana o ka nui o ke kūkulu ʻana, ʻoi aku hoʻi ma muli o ka hoʻomohala wikiwiki ʻana o ke kūkulu ʻana i nā kūlanakauhale kahakai hikina hema, me kahi moʻo o nā kulekele kākoʻo a me nā hana i lawe ʻia e nā luna kūkulu, i hoʻonui ʻia ka sima i hui mua ʻia o ke kūlanakauhale ma 15% i kēlā me kēia makahiki. Ma muli o ke kumukūʻai o ka slag a me ke kila slag haʻahaʻa ma mua o ka sima, ʻo ka sima i hui pū ʻia me ka slag a me ke kila slag he mea waiwai a kūpono hoʻi no ka hoʻohana ʻana i ka sima kalepa i hui nui ʻia. ʻO ka sima i hana ʻia ma ke kāwili ʻana i ka slag a me ke kila slag me ka sima, ka pōhaku a me ke one melemele he mau pono o ka ikaika lohi kiʻekiʻe, ka wela hydration haʻahaʻa, ke kūpaʻa maikaʻi o ka ʻaʻahu a me ka ikaika hoʻopaʻa kiʻekiʻe me nā kaola kila. He kūpono loa ia no nā hale kiʻekiʻe, nā DAMS, nā kahua mokulele, nā kahua hohonu nui a me nā papahana ma lalo o ka wai. I kēia manawa, hoʻomākaukau nui ʻia ka sima ikaika ultra-kiʻekiʻe ma ke kāwili ʻana i ka lehu silica a me ka mea hoʻemi wai kiʻekiʻe, akā ʻo ka nele o nā mea maka lehu silica a me ka mea hoʻemi wai kiʻekiʻe he pipiʻi, e hopena ana i ke kumukūʻai kiʻekiʻe o ka sima. Me nā koi kiʻekiʻe a kiʻekiʻe no nā ʻano sima i nā papahana kūikawā nui, ua wehe ka piʻi ʻana o ke koi no ka sima kalepa i kahi mākeke ākea no ka hoʻohana nui ʻana i ka slag a me ka pauka slag kila. Ke hoʻonui nei ka ʻike o ka poʻe i nā ʻano o ka slag a me ka pauka slag kila, kahi mea hale hou. Me ka hoʻolaha ʻana a me ka hoʻohana ʻana i ka sima kalepa ma ka ʻāina a me ka hoʻokō ʻana i nā kūlana aupuni e pili ana i nā huahana slag a me ka pauka slag kila, a me ka hoʻokō ʻana i nā kulekele e like me ka pāpā ikaika ʻana i ka hoʻohuihui ʻana i ka sima ma nā kahua kūkulu ma nā wahi kūlanakauhale, e nui aʻe ana ka mākeke o ka slag a me ka pauka slag kila, a e ʻoi aku ka nui o ka nānā ʻana i kona hoʻohana ʻana.

3. ua hoʻolaha ʻia a hoʻopili ʻia ke kaʻina hana hoʻomākaukau a me nā lako o ka wili kila slag micro-powder

I kēia manawa, hoʻohana ʻia ka ʻenehana wili kū pololei e wili i ka pauka kila slag micro-pauka a hana i nā huahana e pani i ka clinker sima ikehu kiʻekiʻe, nona ka ʻenehana hana holomua i ka ʻoihana. I ka wā ma mua, ʻo ka slag, ka slag kila a me ka clinker sima, gypsum, a me nā mea ʻē aʻe i hui pū ʻia, e like me kahi hapa o ka wili ʻana i ka hana wili o ka sima. Ma muli o ka maikaʻi ʻole o ka grainability o ka slag a me ka slag kila, ʻaʻole hiki ke wili maikaʻi loa ka wili ʻana i ka wā e hui pū ʻia me ka clinker sima, ʻaʻole hiki ke hoʻomohala piha ʻia kāna hana, a ua kaupalena ʻia ka nui a me ka hoʻohana ʻana o ka slag a me ka slag kila i kahi ʻano. I ka hoʻomākaukau ʻana o ka pauka ultrafine mai ka slag kila wale nō, aia nā ʻoihana hao a me ke kila o Jiangsu ma ke alo. Ua kūkulu kekahi mau ʻoihana kila i hōʻike ʻia e Changzhou Zhongtian Iron and Steel i nā laina hana wili kū pololei slag kila kūikawā. Ma ke ʻano he mea hana wili kū pololei slag kila micro-pauka, hāʻawi ʻo HCM Machinery i ke kākoʻo loea i ke ala hana wili slag kila ultrafine a me ka hana ʻana i nā lako wili kū koʻikoʻi. ʻO kāna mau ʻano loea nā ʻano nui penei: ke koho ʻana o ka pauka kila kila wili wili kū pololei, me ka ʻenehana holomua, ka hana hilinaʻi, nā ʻano hana hana kiʻekiʻe, me ka wili kū pololei e hana i hoʻokahi tona o ka ʻili kikoʻī o 400m2/kg ~ 500m2/kg slag, pauka kila kila, ma mua o ka hana wili pōpō kuʻuna o ke kaumaha like o ka pauka e mālama ana i ka uila 30% ~ 50%; Hoʻohui pololei ʻia ka pauka maikaʻi o ka slag a me ka slag kila i loko o ka sima, kahi e mālama ai i ka nui o ka sima a pēlā e mālama ai i ka hoʻohana ʻana i ka ikehu o ka hana sima. ʻO ka slag, ke kaʻina hana wili slag kila, hiki ke hoʻololi maʻalahi i ka maikaʻi o nā huahana e like me nā pono o ka mākeke. Me ka hoʻonui ʻia o ka hoʻohui ʻana o ka slag a me ka slag kila i loko o ka sima, hiki ke hoʻemi ʻia ka wela hydration a me ka nui o nā ʻāpana ʻino o ka sima, kahi e hana ai i nā kūlana maikaʻi no ka hoʻomaikaʻi ʻana i ka hana o ka sima me ka hoʻohana ʻana i ka ikehu haʻahaʻa. Wili ʻia ka slag kila e ka pauka wili kū pololei, a wili ʻia ka mea i kahi ʻano pulu ma ke kiʻekiʻe o ka mahana (100℃ ~ 300℃). ʻO ka hapa nui o ka calcium oxide manuahi a me ka magnesium oxide manuahi i loko o ka pauka kila kila ua hoʻomaʻū ʻia i loko o ka calcium hydroxide ikaika loa a me ka magnesium hydroxide. Eia kekahi, ma muli o ka hoʻokomo ʻia ʻana o ka slag a me ka slag kila i loko o ka sima, hiki ke hoʻemi pono ʻia ka hopena o ka alkali aggregate, hiki ke pale ʻia nā micro-cracks o ka sima, a hiki ke hoʻolōʻihi ʻia ke ola o nā hale. No laila, ua hoʻokipa ʻia ka sima i hui pū ʻia me ka pauka slag e ka ʻoihana kūkulu hale no kona mau waiwai kū hoʻokahi. Hiki ke hoʻohana ʻia ka wili ʻana i ka slag kila wale nō ma ke ʻano he huahana no ka hana ʻana a me ka hui ʻana o ka sima e like me nā pono o ka mākeke, a hiki ke hoʻoponopono ʻia e like me ka pono e hoʻoponopono i ka fineness a me ka nui o ka hui ʻana e hoʻonohonoho ʻia i loko o ka sima no ke kūʻai aku.

Iron and steel enterprises can take advantage of the existing regional location of steel mills, and the source of raw materials is fully guaranteed; The steel mill has advanced and strict scientific management experience, and has experienced technical team and staff team, which provides the guarantee of organization, technology and production management for the implementation of the project and market development; Steel plant power supply, water supply source reliable, convenient transportation, good cooperation conditions, construction conditions are very superior. To sum up, the construction of steel slag micro-powder projects in iron and steel enterprises can not only turn waste into treasure, improve the added value of steel making, create considerable economic benefits for iron and steel enterprises, but also protect the environment, in line with the policy direction of steel and cement industry structural adjustment. The development of steel enterprises layout steel slag powder project is a good thing to benefit the country and the people, has a broad future and is of great significance, and will play a positive role in promoting the construction of "waste free city" and promoting the sustainable development of the steel industry.
