ʻO ka ʻokoʻa ma waena o ka hoʻolei ʻana i ke kinipōpō kila a me ka hoʻopololei ʻana i ke kinipōpō kila

1.E hoʻolei ana i ka pōleʻa kila: haʻahaʻa chromium kila, medium chromium kila, kiʻekiʻe chromium kila a super kiʻekiʻe chromium kila (Cr12% -28%).

2.Forging kila poepoe: haʻahaʻa kalapona hao kila, kalapona hao kila kila, kiʻekiʻe manganese kila a kakaikahi honua chromium molybdenum hui kila poepoe.

I kēia manawa, he aha ke ʻano o ka pōleʻa kila ʻoi aku ka maikaʻi? I kēia manawa, e nānā kākou:

1.High chromium steel quality index: chromium content is more than 10%, the carbon content in 1.80% -3.20% are called high chromium steel, the requirements of the national standard of high chromium ball hardness (HRC) pono e ≥ 58, AK ≥ 3.0J/cm hopena waiwai o

2.Low chromium steel quality index: me 0.5% ~ 2.5%, ke kalapona maʻiʻo ma 1.80% -3.20% ua kapa 'ia haʻahaʻa chromium kila, nā koi o ke aupuni hae haʻahaʻa chromium kila paakiki (HRC) pono e ≥ 45, AK ≥ 1.5J / cm ka waiwai hopena o ka haʻahaʻa chromium kiʻekiʻe e hōʻoia i ka maikaʻi o ka chromium kiʻekiʻe i ka pōleʻa kiʻekiʻe. vibration elemakule lapaʻau (i mea e hoopau hoolei koʻikoʻi, e like me ka pahuhopu) o ke kila poepoe ili eleele ulaula e hōʻike i ka huahana ua i ka wela wela wela lapaʻau, e like me ke kila poepoe ili ka metala kala hōʻike i ka huahana me ka tempering.

3.Forged kila poepoe quality index: me 0.1% ~ 0.5% (forged kila poepoe me ka chromium), ka carbon maʻiʻo ma lalo o 1% a me ka kila poepoe me kiʻekiʻe wela forging manufacturing, kekahi forged kila poepoe ili paa paakiki (HRC) ≥ 56 (ʻoiai e hiki ke hoʻokō 'oi aku ma mua o quenching papa wale 15 mm a pela aku), kila ballbecause mea paakiki wale no ke kila ballbecause mea paakiki wale no. Ma lalo o nā kūlana maʻamau, forged steel ball by water quenching treatment, the forged steel ball broken rate is high.

4.Comparison o ka lole pale: super kiʻekiʻe chromium kila> kiʻekiʻe chromium kila> waena chromium kila poepoe> haʻahaʻa chromium kila> forged kila poepoe.

Nā ʻāpana o ka pōleʻa kila pale ʻaʻahu:

ʻO ka maʻiʻo Chromium ka 1% - 3% a me ka paʻakikī HRC ≥ 45. Ua kapa ʻia kēia maʻamau o ka pōleʻa kila kila haʻahaʻa haʻahaʻa. Hoʻohana nā pōpō chromium haʻahaʻa i ke kapuahi uila waena, metala a i ʻole ke ʻano hoʻolei one. He kūpono kāna hana no kekahi mau mines metallurgical, slag a me nā ʻoihana ʻē aʻe, he haʻahaʻa haʻahaʻa ka pololei o ka wili a haʻahaʻa.

Wear-resistant steel ball's chromium content is 4% to 6% and hardness HRC ≥ 47. Ua kapa ʻia kēia maʻamau i nā pōpō huila multi-element, ʻoi aku ka kiʻekiʻe ma mua o ke kila chromium haʻahaʻa e pili ana i ka ikaika a me ka pale ʻana a. ʻO 7% - 10% ka maʻiʻo Chromium a ʻo ka HRC ≥ 48 paʻakikī ʻo ia nā pōlele chromium alloy, ʻoi aku ka kiʻekiʻe o kāna hana a me nā ʻano ʻē aʻe ma mua o ka nui o ka pōlele kila kila.

ʻO ka chromium maʻiʻo o ka pōleʻa kila kūʻokoʻa ≥ 10% - 14% a me ka paʻakikī HRC ≥ 58. ʻO nā pōpō hoʻolei chromium kiʻekiʻe he ʻano o ka pōleʻa kila me ke kiʻekiʻe e pili ana a me ka maikaʻi o ke kumukūʻai hana ma ka mākeke o kēia manawa. He laulā kona palapala noi a hoʻohana ʻia i ka metallurgy, cement, thermal power, flue gas desulfurization, magnetic material, chemical, coal water slurry pump; poepoe no laila, pauda superfine, palau, lehu lele, calcium carbonate a me ka oihana quartz-sand. Hōʻike ʻia kāna hana ma ka ʻoihana sima, hiki ke hoʻonui i ka hana a hoʻemi i ka hoʻohana ʻana i ka ikehu.
