ʻO nā ʻano ʻano like ʻole a me nā kaʻina hana me ka holomua o ka ʻenehana metallurgical a me ka hoʻomohala ʻana o nā lako wili kila a me ka hoʻomohala mau.Ma ka waena o ke kenekulia 18, ua akamai ʻo Beretania i ka ʻenehana hana o nā ʻōwili hao maloʻo no ka ʻōwili ʻana i nā papa kila, a ma ka hapa ʻelua o ke kenekulia 19, ʻo ka holomua o ka ʻenehana hana kila ʻEulopa e koi i ka ʻōwili ʻia o nā tonage nui o nā ingots. a ʻaʻole hiki i ka ikaika o ka hao hina hina a i ʻole nā ʻōwili hao anuanu ke hoʻokō i nā koi.ʻO ka maʻiʻo kalapona o 0.4% a 0.6% nā ʻōwili kila kila maʻamau i hānau ʻia e like me ia.ʻO ka puka ʻana mai o nā mea hana forging kaumaha e hoʻomaikaʻi hou i ka paʻakikī o nā ʻōwili palaka o kēia haku mele.ʻo ka hoʻohana ʻana i nā mea hoʻohuihui a me ka hoʻokomo ʻana i ka mālama wela i ka hoʻomaka ʻana o ke kenekulia 20 i hoʻomaikaʻi nui ʻia i ka pale ʻana a me ka paʻakikī o ka hoʻolei ʻana a me ke kila kila wela a me nā ʻōwili anu.ʻO ka hoʻohui ʻana o ka molybdenum e hoʻolei i nā ʻōwili hao no ka pepa i ʻōwili ʻia a hoʻomaikaʻi i ka maikaʻi o ka ʻili o ka mea i ʻōwili ʻia.ʻO ka ninini ʻana o ka hui ʻana ma ke ʻano flushing e hoʻomaikaʻi nui i ka ikaika kumu o nā ʻōwili pahu.
ʻO ka'ōwili i loko o ka nui o nā mea hoʻoheheʻeʻia ma hope o ke Kaua Honuaʻelua,ʻo ia ka hopena o ka'ōwiliʻana i nā mea hana i ka nui-nui, hoʻomau, kiʻekiʻe-wikiwiki, hoʻomohala automate, a me ka'ōwili mea ikaika, deformation kū'ē e hoʻonui i ka'ōwili hana. koi.I loko o kēia wā, ʻike ʻia nā ʻōwili semi-steel a me nā ʻōwili hao ductile, a me ka paukatungsten carbide rollsUa hoʻomohala maikaʻi ʻia ma hope o nā makahiki 1960.Ua hoʻolaha nui ʻia ka ʻenehana hoʻoheheʻe centrifugal a me ka ʻenehana mālama wela wela o nā ʻōwili ma Iapana a me ʻEulopa i ka hoʻomaka ʻana o nā makahiki 1970, kahi i hoʻomaikaʻi nui ai i ka hana holoʻokoʻa o nā ʻōwili pepa.Ua hoʻohana maikaʻi ʻia nā ʻōwili hao kiʻekiʻe-chromium composite ma nā hale wili wela.I ka manawa like, ua hoʻohana ʻia ka hao keʻokeʻo a me nā ʻōwili semi-steel ma Iapana.80s ʻEulopa a me ka hoʻokomo ʻana i nā ʻōwili kila chromium kiʻekiʻe a me ka papa paʻakikī hohonu loa o nā ʻōwili anu a me nā ʻōwili hao hao kūikawā no nā ʻāpana liʻiliʻi a me ka hoʻopau ʻana i ke koʻokoʻo uea.ʻO ka hoʻomohala ʻana o ka ʻenehana wili kila i kēia manawa ua alakaʻi i ka hoʻomohala ʻana i nā ʻōwili hana kiʻekiʻe.ʻO ka hoʻohana ʻana i ka hoʻoheheʻe centrifugal a me nā ʻano hana hoʻohui hou e like me ke ʻano hoʻoheheʻe mau ʻana (CPC method), jet deposition method (Osprey method), electroslag welding method and hot isostatic pressing method e hana i ke kumu o ka paʻakikī maikaʻi o ke kila forged a i ʻole ductile hao, ua hoʻohana ʻia ka papa o waho o nā pūʻulu kila kiʻekiʻe o nā ʻōwili hui a me nā ʻōwili seramika metala ma ʻEulopa, Iapana, he hanauna hou o nā profiles, wire rod, strip mill.
Ua hoʻomaka ʻo Kina e hana i nā ʻōwili hoʻolei ʻana i nā ʻāpana mai nā makahiki 1930, akā he kakaikahi nā ʻano.ka oihana muatungsten carbide rollUa hoʻokumu ʻia ka mea kanu ma Xingtai, Hebei i ka hopena o 1950s.i ka makahiki 1958, ua hana ʻo Anshan Iron and Steel Company i ka hoʻokolokolo honua mua a hoʻohana i nā ʻōwili hao ductile nui no 1050 ka ʻōwili mua.i nā makahiki 1960, ua hana maikaʻi ʻia nā ʻōwili anu a me nā ʻōwili kila nui.i ka hopena o 1970s, Taiyuan hao a me Steel Company a ma ka hopena o 70's, Taiyuan hao a me Steel Company a me Beijing hao a me Steel Research Institute hui pū ana centrifugal hoolei hao olokaa no ka umu ahi wili wili a me ka wela mau broadband kila huila, a Xingtai Metallurgical Machinery Roll Co. a me nā ʻano ʻano hou ʻē aʻe.Ma nā makahiki 1990, ua hoʻokō maoli ka hana ʻōwili a Kina i nā pono kūloko a ua lawe ʻia kekahi hapa, akā pono e hoʻonui ʻia nā ʻano like ʻole a pono e hoʻomaikaʻi ʻia ka maikaʻi.
