Me ka hoʻomohala wikiwiki ʻana o ka ʻoihana kila, i mea e hoʻomaikaʻi ai i ka hoʻopuka ʻana o ke kila a hoʻomaikaʻi i ka hoʻohana ʻana a me ka huahana o ka wili wili, e hōʻemi ana i nā manawa pani o ka wili wili, ʻo ka hoʻohana ʻana i ka tungsten carbide roller me ke ola lawelawe lōʻihi he mea nui. ʻano hana.

He aha ka Tungsten Carbide Roller

ʻO ka huila carbide cemented, ʻike ʻia hoʻi ʻo ke apo wili carbide cemented, e pili ana i kahi ʻōwili i hana ʻia me ka tungsten carbide a me ka cobalt ma o ke ʻano o ka pauka metallurgical. ʻO ka tungsten carbide roll he ʻelua ʻano o ka integral a hui pū ʻia. Loaʻa iā ia ka hana ʻoi aku ka maikaʻi, ka maikaʻi paʻa, ka pololei kaʻina hana kiʻekiʻe me ke kūpaʻa ʻaʻahu maikaʻi loa a me ke kūpaʻa hopena kiʻekiʻe. Hoʻohana nui ʻia ʻo Carbide roller no ka ʻōwili ʻana o ke koʻokoʻo, ke koʻokoʻo uea, ke kila wili a me ka paipu kila ʻole, e hoʻomaikaʻi nui i ka hana o ka wili wili.

Hana Kiʻekiʻe o Tungsten Carbide Roller

He kiʻekiʻe ka paʻakikī o ka carbide roll a liʻiliʻi loa kona waiwai paʻakikī me ka wela. ʻO ka waiwai paʻakikī ma lalo o 700 ° C he 4 mau manawa kiʻekiʻe ma mua o ke kila kiʻekiʻe. ʻO ka modulus elastic, ka ikaika compressive, ka ikaika kulou, ka thermal conductivity he 1 mau manawa kiʻekiʻe ma mua o ke kila mea hana. No ka mea he kiʻekiʻe ka conductivity thermal o ka ʻōwili carbide cemented, maikaʻi ka hopena o ka wela, no laila aia ka ʻili o ka ʻōwili ma lalo o ke kiʻekiʻe wela no ka manawa pōkole a no laila ke kiʻekiʻe o ka wela wela o nā haumia ʻino i loko o ka wai anuanu. ʻoi aku ka pōkole o ka ʻōwili. No laila, ʻoi aku ka kūpaʻa o ka tungsten carbide rollers i ka corrosion a me ke anuanu a me ka luhi wela ma mua o nā mea kila kila.

ʻO ka hana o ka tungsten carbide rollers e pili ana i ka ʻike o ka pae metala paʻa a me ka nui o nā ʻāpana tungsten carbide. ʻO ka tungsten carbide ma kahi o 70% a hiki i 90% o ka nui o ka haku mele a ʻo ka nui o ka nui o ka nui he μm o 0.2 a 14. Inā hoʻonui a hoʻonui paha ka nui o ka carbide metala i ka nui o ka carbide tungsten, e emi ana ka paʻakikī o ka carbide cemented. hoʻomaikaʻi ʻia ka paʻakikī. Hiki ke piʻi ka ikaika o ka tungsten carbide roller apo i 2200 MPa. Hiki ke kiʻi i ka paʻakikī o ka hopena (4 ~ 6) × 106 J / ㎡, a ʻo ka HRA he 78 a 90.

Hiki ke hoʻokaʻawale ʻia ka huila tungsten carbide i ʻelua mau ʻano o ka integral a me ka composite e like me ke ʻano hana. Hoʻohana nui ʻia ʻo Integral tungsten carbide roller i ka ʻōwili mua ʻana a me ka hoʻopau ʻana i ke kūpaʻa o nā mīkini wili uila kiʻekiʻe. Hoʻopili ʻia ka huila carbide cemented composite ma o ka tungsten carbide a me nā mea ʻē aʻe. Hoʻolei pololei ʻia nā huila carbide composite i loko o ka pahu wili, i hoʻopili ʻia i kahi wili wili me ka ukana kaumaha.

ʻO ke ʻano mīkini ʻo Tungsten Carbide Roller a me nā lula koho o kāna mau mea ʻoki ʻoki

ʻOiai ʻoi aku ka maikaʻi o ka mea tungsten carbide ma mua o nā mea ʻē aʻe, paʻakikī i ka mīkini ma muli o ka paʻakikī loa a hoʻohana nui ʻia i ka ʻoihana kila.

1.E pili ana i ka paakiki

I ka hana ʻana i nā ʻōwili tungsten carbide me ka liʻiliʻi liʻiliʻi ma mua o HRA90, koho i ka mea HLCBN a i ʻole BNK30 mea paahana no ka nui o ka huli ʻana a ʻaʻole i haki ka mea paahana. I ka hana ʻana i ka huila carbide me ka ʻoi aku o ka ʻoi aku o HRA90, koho ʻia kahi mea hana daimana CDW025 a wili paha me ka huila daimana resin. ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ka paʻakikī, ʻoi aku ka maikaʻi o ka mea, no laila ʻoi aku ka makaʻala no ka ʻoki ʻana i nā mea paʻakikī kiʻekiʻe a me ka ʻae ʻana i hoʻopau ʻia.

2. ʻO ka'āpana mīkini a me nāʻano hana

IInā hana ʻia ka ʻili o waho a nui ka haʻawina, hoʻohana maʻamau i ka mea HLCBN a i ʻole nā ​​​​mea BNK30 e hana ʻino ʻia, a laila e wili me ka huila wili. No ka haʻawina mīkini liʻiliʻi, hiki ke wili pololei ʻia ka huila me kahi huila wili a i ʻole profiling i hana ʻia e nā mea hana daimana. Ma keʻano laulā, hiki i ka ʻoki ʻana i nā wili ʻē aʻe ke hoʻomaikaʻi i ka hana mīkini a ʻoi aku ka maikaʻi o ke ʻano ʻoki i ka hoʻomaikaʻi ʻana i ka manawa alakaʻi hana.

3.Passivating lapaʻau

I ka hana ʻana i kahi ʻōwili tungsten carbide, pono ka mālama ʻana i ka passivating e hōʻemi a hoʻopau paha i ka waiwai oi, no ke kumu o ka palahalaha a me ka maʻalahi me ka lōʻihi kiʻekiʻe. Eia nō naʻe, ʻaʻole pono ka nui o ka mālama ʻana i ka passivation, no ka mea, ʻoi aku ka nui o ka ʻili pili o ka lau o ka mea hana ma hope o ka passivation a hoʻonui ʻia ke kūpaʻa ʻoki ʻana, hiki ke maʻalahi i kahi māwae, e hōʻino i ka mea hana.

He aha ka mea e uku ʻia ai no ka hana ʻana a me ka hoʻohana ʻana o Tungsten Carbide Roller

I nā makahiki i hala iho nei, ua loaʻa i ka tungsten carbide rollers ka nui a me ka nui o nā noi i ka hana kila me kā lākou hana maikaʻi loa. Eia nō naʻe, aia kekahi mau pilikia i ka hana ʻana a me ka hoʻohana ʻana i nā ʻōwili carbide.

1. E hoʻomohala i kahi ʻano mea hou o ka huila. He mea paʻakikī ke kū ʻana i ka mana ʻoi aku o ka ʻōwili a hāʻawi i kahi torque nui aʻe. No laila, pono e hoʻomohala ʻia nā mea hana kiʻekiʻe cemented carbide composite roll shaft.

2. I ka wā o ka hana ʻana i nā wili carbide, pono e hōʻemi ʻia a hoʻopau ʻia ke koena o ke koʻikoʻi wela ma muli o ka hoʻonui ʻana i ka wela ma waena o ka metala o loko a me waho. ʻO ke koʻikoʻi wela o ka carbide he mea nui ia e pili ana i ke ola o ka roller. No laila, ʻo ka coefficient o ka ʻokoʻa hoʻonui wela ma waena o ka metala i koho ʻia a me ka carbide cemented waho e like me ka liʻiliʻi, ʻoiai e noʻonoʻo ana e hoʻopau i ke koena o ke koʻikoʻi wela o ke apo carbide roller ma o ka mālama ʻana i ka wela.

3. Ma muli o nā ʻokoʻa o ka ikaika o ka ʻōwili, ka ʻōwili ʻana, ka hana hoʻoili wela ma nā ʻokoʻa ʻokoʻa, pono nā ʻano ʻokoʻa e hoʻohana i nā māka like ʻole o ka tungsten carbide rollers e hōʻoia i ka hoʻokūkū kūpono o ka ikaika, paʻakikī, a me ka paʻakikī o ka hopena.

Hōʻuluʻulu manaʻo

No ka ʻōwili ʻana o ka uea, koʻokoʻo, tungsten carbide roller e hoʻololi ana i nā ʻōwili hao maʻamau a me nā ʻōwili kila kila, ua hōʻike nui ʻia ke kūlana kiʻekiʻe, me ka hoʻomau mau ʻana o nā ʻenehana hana ʻenehana a me ka hoʻohana ʻana i ka ʻenehana, e hoʻomau i ka hoʻonui ʻana i nā noi o nā apo carbide roller. a e lilo lākou i mea koʻikoʻi i ka wili ʻana me nā noi ākea.
