ʻO ka ʻokoʻa ma waena o ka hoʻolei ʻana i ka pōpō kila a me ka hoʻoheheʻe ʻana i ka pōpō kila

1. Ke kila kila kila: kila chromium haʻahaʻa, kila chromium waena, kila chromium kiʻekiʻe a me ke kila chromium kiʻekiʻe loa (Cr12% -28%).

2. Ke hoʻoheheʻe ʻana i ka pōpō kila: kila kila kalapona haʻahaʻa, kila kila kalapona waena, kila manganese kiʻekiʻe a me ka pōpō kila kila chromium molybdenum honua kakaikahi:

ʻO wai ke ʻano o ka pōpō kila ka mea maikaʻi loa? I kēia manawa, e nānā kākou:

1. ʻO ke kiʻekiʻe o ka helu kuhi maikaʻi o ke kila chromium: ʻoi aku ka nui o ka chromium ma mua o 10%, ʻo ka nui o ke kalapona ma 1.80% -3.20% i kapa ʻia he kila chromium kiʻekiʻe, ʻo nā koi o ke kūlana aupuni o ka paʻakikī pōpō chromium kiʻekiʻe (HRC) pono e ≥ 58, AK ≥ 3.0J/ cm ka waiwai hopena o

2. Kuhikuhi maikaʻi o ke kila chromium haʻahaʻa: me 0.5% ~ 2.5%, ʻo ka ʻike kalapona ma 1.80% -3.20% i kapa ʻia he kila chromium haʻahaʻa, ʻo nā koi o ke kūlana aupuni haʻahaʻa chromium steel hardness (HRC) pono e ≥ 45, AK ≥ 1.5J/ cm ka waiwai hopena o 2, ʻO ka Rolling Ball i mea e hōʻoia ai i ka maikaʻi o ka pōpō kila chromium haʻahaʻa i ka mahana kiʻekiʻe a i ʻole ka mālama ʻana i ka haʻalulu (i mea e hoʻopau ai i ke kaumaha hoʻolei, e like me ka pahuhopu) o ka ʻili o ka pōpō kila he ʻulaʻula ʻeleʻele e hōʻike ana ua hoʻohana ʻia ka mālama ʻana i ka mahana kiʻekiʻe o ka huahana, e like me ke kala metala o ka ʻili o ka pōpō kila e hōʻike ana i ka huahana me ka ʻole o ka tempering.

3. ʻO ka helu kūlana o ka pōpō kila i hoʻoheheʻe ʻia: me 0.1% ~ 0.5% (pōpō kila i hoʻoheheʻe ʻia me ka ʻole o ka chromium), ʻo ka nui o ke kalapona ma lalo o 1% a me ka pōpō kila me ka hana hoʻoheheʻe wela kiʻekiʻe, kekahi paʻakikī o ka ʻili o ka pōpō kila i hoʻoheheʻe ʻia (HRC) ≥ 56 (ʻoiai hiki ke hoʻokō i ka papa quenching ma mua o 15 mm wale nō a i ʻole), ʻo ka paʻakikī o ka paʻakikī o ka mea pōpō kila i hoʻoheheʻe ʻia he 30 degere wale nō. Ma lalo o nā kūlana maʻamau, he kiʻekiʻe ka wikiwiki o ka haki ʻana o ka pōpō kila i hoʻoheheʻe ʻia me ka wai.

4. Hoʻohālikelike o ke kūpaʻa ʻaʻahu: kila chromium kiʻekiʻe loa > kila chromium kiʻekiʻe > pōpō kila chromium waena > kila chromium haʻahaʻa > pōpō kila i hoʻoheheʻe ʻia.

Nā ʻāpana o ka pōpō kila kūpaʻa:

ʻO ka nui o ka chromium he 1% - 3% a ʻo ka paʻakikī HRC ≥ 45. ʻO kēia kūlana o ka pōpō kila pale ʻaʻahu i kapa ʻia he pōpō hoʻolei alloy chromium haʻahaʻa. Hoʻohana nā pōpō chromium haʻahaʻa i ke ʻano umu uila alapine waena, ka ʻōmole metala a i ʻole ke ʻano hoʻolei one. He kūpono kāna hana no kekahi mau mines metallurgical, slag a me nā ʻoihana ʻē aʻe, nona ka pololei wili haʻahaʻa a me ka hoʻopau haʻahaʻa.

ʻO ka nui o ka chromium o ka pōpō kila pale ʻaʻahu he 4% a 6% a ʻo ka paʻakikī HRC ≥ 47. Ua kapa ʻia kēia kūlana he mau pōpō alloy multi-element, ʻoi aku ke kiʻekiʻe ma mua o ke kila chromium haʻahaʻa e pili ana i ka ikaika a me ke kūpaʻa ʻaʻahu. ʻO ka nui o ka chromium he 7% - 10% a ʻo ka paʻakikī HRC ≥ 48 he mau pōpō hoʻolei chromium alloy, nona ka hana a me nā ʻano ʻē aʻe he kiʻekiʻe ma mua o ka pōpō kila alloy he nui.

ʻO ka nui o ka chromium o ka pōpō kila pale ʻaʻahu he ≥ 10% - 14% a me ka paʻakikī HRC ≥ 58. ʻO nā pōpō hoʻolei ʻia me ke chromium kiʻekiʻe he ʻano pōpō kila pale ʻaʻahu me ka uku kūpono kiʻekiʻe a me ka hana kumukūʻai maikaʻi ma ka mākeke o kēia manawa. He ākea kona laulā noi a hoʻohana ʻia i ka metallurgy, sima, mana wela, desulfurization kinoea flue, nā mea magnetic, kemika, ka pamu slurry wai lanahu; no laila, ka pōpō, ka pauka superfine, ka slag, ka lehu lele, ka calcium carbonate a me ka ʻoihana quartz-one. Hoʻokūkala nui ʻia kāna hana ma ka ʻoihana sima, hiki ke hoʻonui i ka hana a hōʻemi i ka hoʻohana ʻana i ka ikehu.
