ʻO nā mea i hoʻohui ʻia i ke kila ʻoki manuahi e komo pū me S, Pb, Ca a me P. ʻO kā lākou mau hana nui penei:
1. Ke kuleana o ka sulfur
Hoʻokumu ka sulfur i nā hoʻokomo MnS me Mn i loko o ke kila, hiki ke hoʻopilikia i ka hoʻomau ʻana o ka matrix, e maʻalahi ka haki ʻana o nā ʻāpana, a hoʻemi i ka wahi pili ma waena o nā ʻāpana a me ka mea hana. Hiki i ka sulfur ke hoʻemi i ka friction a pale i ka pipili ʻana o nā ʻāpana i ka lihi ʻoki. Eia nō naʻe, hiki i ke alo o ka sulfur ke hoʻomehana a palupalu ke kila, no laila ua kaupalena ʻia ka nui o ka sulfur i ka pae o w(s)=0.10%~0.30%, a pono e hoʻonui pono ʻia ka nui o ka Mn e kūlike me ia.
2. Ke kuleana o ke alakaʻi
Hiki i ka hoʻohui ʻana o Pb ke hoʻomaikaʻi i ka hana ʻoki o ke kila. ʻOiai ʻaʻole hoʻoheheʻe ʻia ʻo Pb i loko o ka ferrite i loko o ke kila a ʻaʻole hoʻi e hana i nā hui, aia ia i loko o kahi mokuʻāina manuahi a hana i nā ʻāpana liʻiliʻi (2 ~ 3μm) i hoʻolaha like ʻia i loko o ka ʻōnaehana matrix. Ke hiki ka wela i hana ʻia i ka wā o ke kaʻina hana ʻoki i kahi heheʻe o nā ʻāpana Pb, aia ia i loko o kahi mokuʻāina heheʻe a lilo i "lubricant" ma waena o ka mea hana a me nā ʻāpana a ma waena o ka mea hana a me ka ʻili o ka workpiece, e hōʻemi ana i ka friction factor, ka mahana o ka mea hana, a me ke komo ʻana. ʻO ka nui o Pb i hoʻohui ʻia aia ma ka pae o w(Pb)=0.1%~0.35%.
3. Ke kuleana o ka calcium
Hiki iā Ca ke hana i nā Ca a me Al silicate inclusions i loko o ke kila, e pili ana i ka mea hana e hana i kahi ʻili lahilahi, loaʻa ka hopena hōʻemi friction, a pale i ka ʻaʻahu ʻana o ka mea hana. ʻO ka nui o Ca i hoʻohui ʻia ma ke ʻano laulā he w(Ca)=0.001%~0.005%.
4. Ke kuleana o ka phosphorus
Hoʻohui ʻia ʻo P i ke kila ʻoki manuahi i loaʻa ka sulfur e hoʻoheheʻe iā ia i loko o ka ferrite, e hana ana i ka hoʻoikaika a me ka embrittlement e hoʻomaikaʻi i kāna hana ʻoki. I mea e pale ai i ka "cold brittleness", ua kuhikuhi ʻia ʻo w(P) he ≤0.15%.
Hiki i ka hoʻohui ʻana o kēia mau mea ke hoʻomaikaʻi i ka maikaʻi o ka ʻili o ka workpiece a hoʻolōʻihi i ke ola lawelawe o ka mea hana.

Inā makemake ʻoe i ka ʻike kikoʻī hou aku, ua ʻōlelo ʻia e nīnau mai iā mākou no ka ʻike kikoʻī e pili ana i nā kikoʻī kikoʻī a me nā hoʻohana ʻana o kēia mau kaola kila metala.

Q: He mea hana ua?

A: ʻAe, he mea hana mākou. Loaʻa iā mākou kā mākou hale hana ponoʻī ma ke kauhale ʻo Daqiuzhuang, ke kūlanakauhale ʻo Tianjin, Kina. Eia kekahi, ke hana pū nei mākou me nā ʻoihana aupuni he nui, e like me BAOSTEEL, SHOUGANG GROUP, SHAGANG GROUP, a pēlā aku.
