Cr12 wela olokaa kila poepoe kaola

ʻO ke kila Cr12 he kila kila kila maʻamau, ʻo Cr12 he kila kila hana ʻāwili Kina. Maikaʻi loa kāna Cold work Mechanical Properties. Cr12 kila me ke kiʻekiʻe abrasion kū'ē, micro deformation o ke anuanu hana make kila, ka makani paʻakikī kila kila, kalapona maʻiʻo e like me 1.5%, chromium maʻiʻo i ke kiʻekiʻe e like me 11.5%, ka wela lapaʻau paakiki hiki i 60 HRC. Hiki ke hoʻohana ʻia ke kila ʻāpana Cr12 i:

a) hoʻohana nui ʻia ka silicon die no nā kūlana loaGBg ikaika liʻiliʻi e koi i ke kūpaʻa lole kiʻekiʻe, ke kaha kiʻi maʻalahi a me ka make blanking.
b ʻO ka ʻōnaehana no ka hana ʻana i nā mold benGBg e koi ana i ka lole kiʻekiʻe, ke ʻano paʻakikī o ka punch, make, hoʻokomo, hana punch, ke ʻōlelo ʻia ka make, paʻakikī 60 ~ 64HCR.
c) no ka hana ʻana i ke kiʻi ʻana i ka lole make make e pono ai, ʻoi aku ka paʻakikī 62 ~ 64HCR.
d) no ka anti-anu alumini extrusion make punch, ua paipai 'ia ka paakiki 60 ~ 62HCR.
e) no ka benGBg carbon maʻiʻo o 0.65% a 0.80% hōʻoia builGBg kila, paakiki 60 ~ 62HCR.
f) hiki ke hoʻohana no ka blanking die, punch, rolling wheels, shear blades, cool heaGBg die, clay mold.
g) hiki ke hoʻohana ʻia no nā molGBg plastic thermoset.

Ka hana ʻana i nā mea kila Cr12

E hoʻomaha mālie i ka 900 ~ 950 ° C a laila e hoʻonui wikiwiki i ka mahana i 1050-1100 ° C. Mai hoʻopaʻa i lalo o 1020 ° C. A laila e hoʻolili mālie i ka Cr12 ma hope o ka hana ʻana.

Hoʻopili i nā mea kila Cr12

Hāʻawi ʻia ke kila kila GB Cr12 i ke kūlana maʻamau i ka annealing a me ka mīkini. Inā pono e hoʻopili hou. E wela i ke kila Cr12 900 °C a e hoʻomoʻa maikaʻi, a laila e hoʻolili i ka umu. Ma hope o ka hoʻopili ʻana, ʻo 255HB Max ka paʻakikī Cr12.

Hoʻopau koʻikoʻi o ka mea kila Cr12

I ka wā e pono ai e hana ʻia nā mea hana mai ka Cr12 alloy tool steel e hana nui ʻia a i ʻole ka lepo, ʻoi aku ka maikaʻi o ka hoʻomaha ʻana o nā ʻāʻī o loko ma mua o ka paʻakikī e hōʻemi i ka hiki ke hoʻololi. Pono nui ka hoʻomaha ʻana i ke kaumaha, pono e hana ʻia ka hoʻoluhi ʻana ma hope o ka mīkini paʻakikī. No ka hoʻomaha ʻana i ke koʻikoʻi, e hoʻomaʻamaʻa pono i ka ʻāpana a hiki i 600-650 ° C, e ʻae i kahi manawa hoʻoluʻu maikaʻi (ʻelua hola no 25mm o ka pauku hoʻoholo). Hoʻolili i ka umu a i ʻole ka ea. E hoʻopau ʻia nā mea hana ma mua o ka paʻakikī.

ʻO ka paʻakikī o nā mea kila Cr12

ʻO GB Cr12 ʻO ke kūlana hoʻouna maʻamau ʻo Annealing, no laila pono ka paʻakikī. E wela i nā mea hana Cr12 i loko o ka umu ahi i hoʻomalu ʻia, inā ʻaʻole i loaʻa ka umu hoʻomalu, ʻoi aku ka ikaika o ka paʻakikī paʻa. E hoʻomaʻamaʻa mua i ke kila mea hana Cr12 i 750~800°C, e hoʻomoʻa i ka manawa kūpono a hiki i ka wela. A laila lawe ʻia i ka 1000-1040 °C, hoʻoluʻu i ka ea a i ʻole ka aila kinai.

ʻO ka hoʻouluʻana o ka mea kila Cr12

E wela i ka GB Cr12, E wela i ka wela i makemake ʻia e hiki ai i ʻelua hola no ka 25mm o ka pauku hoʻoholo. Wehe ʻia mai ka umu ahi a hoʻomaloʻo i ka ea. E loaʻa i ka ʻokoʻa ka paʻakikī o ka tempering wela. ʻO 204 ° C ka hana maʻamau, ma hope o ka paʻakikī 61HRc Min.

Kuʻihao o Cr12 mea kila

Ma keʻano laulā, ʻaʻole mākou e aʻo i ka welGBg o ke kila kila kila akā makemake nā mea hoʻohana i kekahi manawa e wili i mea e pale aku ai i ke kumukūʻai o ka hana hou ʻana. Pono e hoʻomanaʻo ʻia he kila paʻakikī ea kēia papa a ma ka welGBg ka wahi o ka weld e loaʻa i kahi mahana o kahi 1000 ° C. Hiki mai paha ka pohā i ka wā ho'olu'u ke 'ole e mālama pono 'ia. ʻO nā ala kaulana o ka welGBg he hydrogen atomic a me argon arc. Paipai mākou iā ʻoe e hoʻokaʻaʻike i kāu mea hoʻolako mea hoʻohana welGBg nāna e hāʻawi iā ʻoe i ke kōkua piha a me ka ʻike e pili ana i nā kila mea hana welGBg.

Nitriding o Cr12 mea kila

Hiki ke hoʻokaʻawale ʻia ke kila kila kila Cr12 e hāʻawi i kahi hihia paʻakikī. Ma hope o ka mālama ʻana i ka wela nitriGBg, ʻaʻole kūʻē ka Cr12 i ka ʻaʻahu a me ka ʻino. Hoʻonui pū ʻo NitriGBg i ka pale ʻana i ka corrosion.

ʻO ka wili hope loa o nā mea kila Cr12

GringGBg ka GB Cr12 Steel. E koho i ka helu kūpono o ka huila ma ke kūkākūkā me ka mea hana huila gringGBg. E hōʻoia i ke kūlana maikaʻi o ka huila gringGBg ma o kahi mea hana lole kūpono. ʻO Wet gringGBg kahi koho ʻoi aku ka maikaʻi me ka hoʻohana ʻana i kahi lako o ka mea hoʻomaha. Inā hoʻohana ʻia ka gringGBg maloʻo a laila e hoʻohana i kahi huila palupalu loa.
