Nā māka maʻamau o ke kila hoʻolālā ikaika kiʻekiʻe

Aloha~ I kēia lā e hoʻolauna aku au iā ʻoe i nā māka i hoʻohana mau ʻia o ke kila kila kiʻekiʻe
Hana ʻia ke kila kila kiʻekiʻe haʻahaʻa haʻahaʻa ma ka hoʻohui ʻana i kahi liʻiliʻi o nā mea hoʻohui i ke kila kila (Wc=0.16% ~ 0.2%).ʻO ke ʻano o kona koho ʻana he ʻano like ia me ke kila structural carbon.No laila he aha nā helu maʻamau aupuni nui?
(E aʻo hou e pili ana i ka hopena o nā huahana kila kūikawā, e like meikaika kiʻekiʻe qt 100 pā kila, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou)
ʻO nā māka maʻamau o ke kila ikaika kiʻekiʻe maʻamau ʻo Q420B, Q460C, Q550D, Q690D, Q890D, a me Q960E.
(Inā makemake ʻoe e ʻike hou aku e pili ana i ka nūhou ʻoihana mas460j0 pā kila ikaika kiʻekiʻe, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa)
ʻO ke kila kila ikaika kiʻekiʻe he Q + helu + hōʻailona papa maikaʻi + hōʻailona deoxidation method.ʻO ka "Q" ka helu o ke kila, a ʻo ka helu waena e hōʻike ana i ka waiwai o ka helu hua, a ʻo ka ʻāpana he MPa.No ka la'ana, Q420B 'o ia ho'i, 'o ke ko'iko'i o ka hua (σs) he 420 MPa, a 'o ka papa B-grade ke kila kila.Loaʻa i nā māka Q420 nā māka B, C, D, a me E, a ʻo ke kūlana hoʻopuka e pili ana i ka ʻōwili wela, ka hoʻomaʻamaʻa ʻana, ka ʻōwili maʻamau, a me ka ʻōwili mechanical wela (TMCP).
(Inā makemake ʻoe e kiʻi i ke kumukūʻai o nā huahana kila kūikawā, e like mehaʻahaʻa haʻahaʻa ikaika ikaika pā kila, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou no ka ʻōlelo i kēlā me kēia manawa)

ʻO ke kumu nui
ʻO ke kila kila kiʻekiʻe ka ikaika kiʻekiʻe, ka plasticity maikaʻi a me ka hana kuʻi ʻana, a hoʻohana nui ʻia i ka hana ʻana i nā hale metala a me nā ʻāpana hana welded o nā hale kiaʻi hao hao, nā alahaka, kemika, ka mining, nā mīkini ʻenekinia a me nā mea hana ʻē aʻe;hiki ke hoʻohana ʻia i ka mining a me nā lako like ʻole i hoʻohana ʻia i ka hana ʻenekinia, e like me nā rigs drilling, nā koʻi uila, nā kaʻa hoʻokuʻu huila uila, nā excavators, loaders, bulldozers, nā kaʻa pahu pahu, nā alapiʻi ahi, nā cranes like ʻole a me nā kākoʻo hydraulic maina lanahu, etc. .
