pā pale ʻaʻano ʻaʻahu

Hōʻike Pōkole:

Hōʻike i ka pale aniani pale e pili ana i nā papa pale pale pale ʻē aʻe i hana ʻia mai ka papa kila kila ma o nā kaʻina hana e like me keʻoki ʻana, ka hoʻoheheʻe ʻana o ka papa, ka ʻeli ʻana a me ka hoʻoheheʻe ʻana, e like me ka papa hoʻoili conveyor, ka pā hānai feeder lalo / cyclone huli i hoʻohuli ʻia. ʻO ka pā, ka pale pale pale, a me nā mea ʻē aʻe hiki ke ola ʻoi ke pale ma mua o 15 mau manawa ke kiʻekiʻe ma mua o ka papa kila maʻamau.


ʻIke kikoʻī

Nā huahana huahana

Lawe i ke aniani kila kūpaʻa, he ʻāpana ʻaukā paʻa paʻa i haku ʻia o nā karbida Cr7C3 me ka hapa nui o nā mea i ʻoi aku ma mua o 50% i hoʻokumu ʻia e ka pae ʻana i ka papa kila maʻamau, papa kila kila a me nā pā kila kila.

Lawe i ke aniani kila papa kiʻekiʻe kiʻekiʻe ʻaʻa, hopena hopena, deformability a me ka weldability. Hiki ke hoʻoponopono pololei ʻia i nā ʻenehana ʻenekini e like me ka pā kila, e like me ka deimpation crimping, ka ʻoki ʻana a me ke ʻeli ʻana, i mea e hoʻokō ai i nā pono o nā ʻoihana pale-awale a me nā mines.

Nā palena hana hana huahana

Ka nui ≥ 3.6 g / cm3

ʻO ka paʻakikī ʻo Rockwell ≥ 85 HRC

Kēkelē puʻe ≥ 850 MPa

Pā paʻa paʻa K Ι C ≥4.8MPa · m1 / 2

Piko kūlou ≥ 290mpa

ʻOhana conductivity 20W / mk

Coefficient o thermal hoʻonui: 7.2 × 10-6m / mK

Hoʻohālikelike ʻia me nā mea pale pale ʻole he nui, pale pale pale kila paʻa paʻa i nā ʻano irreplaceable:

1. ʻO ka hoʻohui kemika o ka papa hana paʻa paʻa kūʻē kiʻekiʻe i loaʻa ka ʻona kalapona o 4 ~ 5% a me ka ʻike chromium o 25 ~ 30%. ʻO ka hapa nui o ka Cr7C3 carbide i loko o ka metala metalgrgricic ʻoi aku ma mua o 50%, ʻo ka paʻakikī paʻakikī he hrc56 ~ 62, a ʻo ka paʻakikī o chromium carbide ʻo hv1400 ~ 1800, ʻoi aku ke kiʻekiʻe ma mua o ka quartz i ke one HV800 ~ 1200. No ka mea Hoʻokaʻawale ʻia nā karbides i ke kuhikuhi ʻaʻahu, ʻoi aku ka pāpālua o ke kūpale ʻana ke hoʻohālikelike ʻia me ka mea hoʻoheheʻe ʻia me ka ʻano like a me ka paʻakikī.

2. Hoʻohālikelike ʻia me nā ʻano hana like ʻole, penei ke kūpaʻa ʻaʻahu:

(1) A me nā kila kila; 20 ~ 25 :

(2) A me ke kila manganese kiʻekiʻe; 5 ~ 10 :

(3) A me nā mea kila kila; 5 ~ 10 :

(4) A e like me ka hoʻolei ʻana i ka chromium kiola hao kiʻekiʻe; 1.5 ~ 2.5 :

2. ʻO ke kūpaʻa hopena maikaʻi: ʻo ka papa o lalo o ka pale kila paʻa paʻa paʻa he haʻahaʻa kalapona kila a me ke kinikini haʻahaʻa. Hōʻike nā mea kila kila a me nā mea ductile i nā pono o nā bimetals. Ke pale nei ka pale pale ʻaʻahu i ka ʻaʻahu o ka pāpaho lole, a lawe ka substrate i ka ukana o ka pāpāho, no laila he hopena hopena maikaʻi ia. Hiki iā ia ke kū i ka hopena a me ke kau ʻana o ka hopper hāʻule kiʻekiʻe i ka ʻōnaehana lawe i nā mea.

3. ʻO ke kūpaʻa wela maikaʻi: paipai ʻia e hoʻohana i ka pale o ka pale lole ma lalo o ke ʻano hana o ≤ 600 ℃. Inā hoʻohui ʻia ka vanadium, molybdenum a me nā mea hoʻohui ʻē aʻe i ka papa oka, hiki iā ia ke kū i ka wela wela o ≤ 800. Penei ke ʻano o ka mahana hana i koi ʻia: e noi ʻia e hoʻohana ʻia ma lalo o ke kūlana hana o ke kiʻekiʻe o 380 ℃; Pākuʻi hao wela hoʻopale wela (15CrMo, 12Cr1MoV, a pēlā aku) e koi ʻia e hoʻohana ma lalo o ke ʻano hana o 540 ℃; Paipai ʻia ka substrate kuhiliʻole kū wela i hoʻohana ʻia ma lalo o ke ʻano hana o ka ʻole ma mua o 800 ℃.

4. ʻO ka papa hana paʻa o ka pā kila kila paʻa me ka pale kūpale maikaʻi i loaʻa kahi pākēneka kiʻekiʻe o ka chromium metala, no laila aia kekahi pale ʻana i ka popo a me ka pale kūpaʻa. Hoʻohana ʻia ia i ka chute lanahu a me ka funnel e pale ai i ka hoʻopili ʻana o ka lānahu.

5. ʻO ka applicability ikaika, pale pale pale pale pale pale pale i loaʻa ka laulā o nā kikoʻī a me nā ʻano, a ua lilo i huahana huahana. ʻO ka mānoanoa o ka pale paʻa paʻa paʻa o 3 ~ 20mm. ʻO ka lahilahi mānoanoa o ka papa kila kila he 6mm, a ʻaʻohe palena ka mānoanoa. Hiki i ka papa kila paʻa paʻa paʻa paʻa ke hāʻawi iā 1200 a i ʻole 1450 × 2000mm, a i hoʻopilikino ʻia e like me ka nui o ke kaha kiʻi e like me ka makemake o ka mea hoʻohana. Lawe ʻia i kēia manawa ka papa kila kila kūpale i ka ʻano maʻamau, ka hopena kūpaʻa hopena a me ke ʻano wela kiʻekiʻe. Pono e wehewehe ʻia ke ʻoka ʻana i ke aniani pale kiʻekiʻe a me ka hopena e pale i ka pā kila kila.

6. Hiki ke ʻoki, pae ʻia, hana ʻia i ke kaʻina hana kūpono hiki ke ʻoki, pae, perforated, kūlou a crimped. Hiki ke hana i loko o ka pā pālahalaha, ka pā arc, ka pā cone a me ka paukūʻolokaʻa. Hiki keʻoki ʻia ka pā i ʻokiʻoki ʻia i nā ʻāpana hoʻolālā ʻenehana a i ʻole ʻāpana. Hiki ke hoʻomehana ʻia ka pā hui a kāomi ʻia i loko o kahi ʻano paʻakikī me kahi puna. Hiki ke hoʻopaʻa ʻia ka pā kila hoʻohui paʻa i ka pono ma o nā hoʻopaʻa a hoʻopaʻa paha, kahi maʻalahi no ka pani a me ka mālama ʻana.

7. ʻOiai ua hoʻonui ʻia ke kumukūʻai hana, hoʻonui ʻia ke ola lawelawe i nā manawa he nui, kahi e hoʻēmi nui ai i ka uku mālama a me ka pohō pani. ʻO kāna hana kumukūʻai ma kahi o 2 ~ 4 mau manawa ke kiʻekiʻe ma mua o nā mea maʻamau. ʻO ka nui o ka hiki o ka mālama ʻana i nā mea a ʻoi aku ka koʻikoʻi o nā pono o nā pono hana, ʻoi aku ka maopopo o ka hopena o ka hoʻokele waiwai o ka hoʻohana ʻana i ka papa kila kila paʻa.

Ka hoʻoholo ʻana i ke kūpaʻa ʻaʻahu

Ke waena waena ka wili ʻana o nā mea (slag Bond hana index 20, ʻai pākaina Bond hana papa kuhikuhi 10, lanahu Hastelloy index index 75 a tona ʻai o 3G / T), ka maʻamau hana manawa o ka lole-hoʻopale ʻāpana o ka slag vertical mill ma hope o ka heʻe ʻana. hiki i nā hola 1800 ~ 2000, hiki i ka manawa hana o nā ʻāpana pale pale o ka wili palaoa kū i mua o 7000 mau hola, a me ka manawa hana o nā ʻāpana pale pale o ka palaoa wili maka hiki ke piʻi aku ma mua o 7000 mau hola Ke hiki i ka manawa hana o ʻaʻahu nā ʻāpana pale o ke kinikini clinker vertical mill ma mua o 2500 mau hola a ʻo ka manawa hana o ka roller extrusion i ʻoi aku ma mua o 4000 mau hola (ma hope o ka hoʻouka ʻana i ka pūnaewele) ~ 8000 mau hola (ma hope o ka hemo ʻana ma waho pūnaewele) ma hope o ka heʻe ʻana e hālāwai i nā koina e makemake ai i ka lole e pono ai.

No nā wili pale pale wili paʻa me nā mea hoʻolei kumu kiʻekiʻe o ka hao chromium kiʻekiʻe a i ʻole nickel hard Ⅳ, ʻaʻole e hāʻule ka papa heʻe i loko o 3 mau mahina ma hope o ka hana hou ʻia ʻana o ka surfacing a hoʻokomo i ka hana.
