ʻO kahi hua'ōlelo maʻamau no nā mea kila me ke kūpaʻa paʻa ikaika, ʻo ke kila kila ka mea i hoʻohana nui ʻia i kēia lā.

Hoʻokaʻawale

Nui nā ʻano o ke kila ʻaʻahu, hiki ke hoʻokaʻawale ʻia i ke kila manganese kiʻekiʻe, ke kila kila a me ka haʻahaʻa haʻahaʻa, chrome-molybdenum-silicon-manganese steel, cavitation-resistant steel, wear-resistant steel and special wear. -kūʻai kila.Hoʻohana pū ʻia kekahi mau kila hoʻoheheʻe maʻamau e like me ke kila kila, ke kila kila, ke kila kila kila a me ke kila hoʻoheheʻe ʻana i hoʻohana ʻia e like me ke kila ʻaʻahu ma lalo o nā kūlana kikoʻī.Ma muli o ko lākou kumu kūpono a me ka hana maikaʻi loa, hoʻohana ʻia lākou i ka hoʻohana ʻana i ke kila pale.kekahi pākēneka.

haku mele

Loaʻa i nā kila kila a me ka haʻahaʻa haʻahaʻa nā mea kemika e like me ke silicon, manganese, chromium, molybdenum, vanadium, tungsten, nickel, titanium, boron, copper, rare earth, etc. ma ʻAmelika Hui Pū ʻIa i hana ʻia me chrome-molybdenum-silicon-manganese a i ʻole chrome-molybdenum kila.ʻO ka hapa nui o nā pōpō wili ma ʻAmelika Hui Pū ʻIa i hana ʻia me ke kila chrome molybdenum medium a kiʻekiʻe.No nā mea hana e hana ana ma lalo o nā kūlana ʻaʻahu abrasive i nā mahana kiʻekiʻe (e like me 200 a 500 ° C) a i ʻole nā ​​​​mea hana i hoʻokuʻu ʻia ka ʻili i nā wela kiʻekiʻe ma muli o ka wela frictional, nā alloys e like me chrome-molybdenum-vanadium, chrome-molybdenum-vanadium-nickel. a i ʻole chrome-molybdenum-vanadium-tungsten alloys hiki ke hoʻohana.ʻO ka wili kila, ma hope o ka hoʻopau ʻia ʻana o kēia ʻano kila a hoʻonāuki ʻia i ka mahana wela a i ʻole ke kiʻekiʻe, aia kahi hopena paʻakikī lua.

Hoʻohana nui ʻia ke kila pale ʻaʻahu i nā mīkini mining, ʻeli lanahu a me ka lawe ʻana, nā mīkini hana, nā mīkini mahiʻai, nā mea kūkulu hale, nā mīkini uila, ka lawe kaʻaahi a me nā keʻena ʻē aʻe.No ka laʻana, nā pōpō kila, nā papa wili o nā wili pōleʻa, nā niho bakeke a me nā bākeke o nā mea ʻeli, nā paia palaki ʻolokaʻa, nā papa niho a me nā poʻo hāmare o nā mea paʻi like ʻole, nā kāmaʻa track o nā tractors a me nā pahu, nā papa kuʻi o nā wili peʻahi, nā ala kaʻaahi Forks, waena. groove-in-plates, grooves, circular chains for scraper conveyors in lanahu mines, blades and niho for bulldozers, linings for large electric wheel truck bckets, roller cone bits for perforating oil and opencast iron ore, etc. i kaupalena ʻia i ka hoʻohana ʻana i ke kila ʻaʻahu i hoʻopaʻa ʻia i ka lole abrasive, a ʻo nā ʻano mea hana āpau me ka neʻe pili i nā mīkini like ʻole e hana i nā ʻano lole like ʻole, e hoʻomaikaʻi ai i ke kūʻē ʻana o nā mea hana.ʻO nā koi Grindability a i ʻole ka hoʻohana ʻana i ke kila ʻaʻahu, he nui nā hiʻohiʻona.ʻO nā mea wiliwili (nā pōpō, nā koʻokoʻo a me nā laina) i hoʻohana ʻia i ka ʻaila a me nā wili sima he mau ʻāpana lole kila.Ma ʻAmelika Hui Pū ʻIa, hana ʻia a hoʻolei ʻia paha nā pōlele wili me ke kalapona a me nā kila kila, ʻo ia ka 97% o ka nui o ka hoʻohana ʻana i ka pōlele wili.Ma Kanada, he 81% o na pōpō wili i pau.Wahi a nā helu helu i ka hopena o nā makahiki 1980, ʻo ka ʻai makahiki o Kina i ka wili pōleʻa ma kahi o 800,000 a 1 miliona mau tona, a ʻo ka hoʻohana makahiki ʻana o nā linings wili ma ka ʻāina he kokoke i 200,000 tons, ʻo ka hapa nui o ia mau huahana kila.ʻO ka lua waena o ka mea lawe ʻōpala i ka lua lanahu o Kina e hoʻopau i 60,000 a 80,000 tons o nā papa kila i kēlā me kēia makahiki.
