Alakaʻi Koho Papa Kumu no ka Papa ʻAʻahu Chromium Carbide Overlay: Q235 vs. Q355

No ke aha he mea nui ke koho ʻana i ka papa kumu

I loko o kahipā uhi uhi chromium carbide, hāʻawi ka papa uhi i ke kūpaʻa koʻikoʻi i ka abrasion, akā ʻo ka papa kumu ke iwi kuamoʻo e hāpai ana i nā ukana kūkulu, omo i ka hopena, a hōʻoia i ka hana kuʻihao hilinaʻi.

ʻO ke koho ʻana i ka mea papa kumu kūpono—ʻo ka mea maʻamau ʻo Q235 a i ʻole Q355—e pili pololei ana i ke ola lawelawe, ke kūpaʻa o ka hana, a me ke kumukūʻai kūpono.

ʻIkepili o nā kila Q235 a me Q355

Q235: Kila Māmā me nā Noi Maʻalahi

He kila kūkulu haʻahaʻa kalapona ʻo Q235 i hoʻohana nui ʻia i ka ʻenekinia laulā. Loaʻa ia i nā papa A, B, C, a me D, me nā papa kiʻekiʻe e hāʻawi ana i ka paʻakikī haʻahaʻa haʻahaʻa.

• Ikaika hua: ~235 MPa
• Ikaika tensile: 370–500 MPa
• Nā Pōmaikaʻi: Weldability maikaʻi loa, ductility maikaʻi, mālama kālā
• Paʻakikī kikoʻī papa:
• A/B: Kūpono i ka mahana o ka lumi
• C: Hilinaʻi a hiki i ka 0°C
• D: Hana maikaʻi a hiki i -20°C

Q355: Kila Kūkulu Ikaika Kiʻekiʻe

ʻO Q355, like me EN S355, he kila ikaika kiʻekiʻe haʻahaʻa-alloy i hoʻolālā ʻia no nā ukana kaumaha a me nā kūlana ʻoi aku ka paʻakikī.

• Ikaika hua: ~355 MPa
• Ikaika tensile: 470–630 MPa
• Nā Pōmaikaʻi: Ka nui o ka ukana, ke kūpaʻa hopena kiʻekiʻe, ka hiki ke hoʻopili maikaʻi ʻia, ka hana haʻahaʻa haʻahaʻa maikaʻi loa
• Nā noi: Nā lako hana mining, nā mīkini awa, nā ʻāpana kūkulu hana kaumaha

Hoʻohālikelike Hana Koʻikoʻi

Ka mana ma luna oChromiumHana Hoʻopili Carbide

Ke hoʻohana ʻia ma ke ʻano he kumu o kahiPapa uhi Chromium Carbide, ʻo nā waiwai mechanical o ke kila e hoʻoholo ai i ka maikaʻi o ka hana o ka papa overlay i nā kūlana honua maoli.

Ka Hoʻopili ʻana o ka Hopena:

• He kūpono ka Q235 no nā wahi hopena kaulike e like me nā paipu hana sima a i ʻole nā ​​​​​​hoppers.
• Hoʻohana ʻo Q355 i nā ukana hopena kiʻekiʻe i loko o nā bākeke mining, nā liner crusher, a me nā pahi dozer.

Hilinaʻi o ke Anuanu:

• Hiki i ka Q235C/D a me ka Q355 ke mālama i ka paʻakikī i nā mahana ma lalo o ka zero.
• ʻO nā papa haʻahaʻa e like me Q235A/B ka pilikia o ka palupalu i nā aniau anuanu.

Ka Pono Kūkulu:

• ʻO ka ikaika kiʻekiʻe o ka Q355 e ʻae ai i nā papa kumu lahilahi me ka ʻole o ka mōhai ʻana i ka ikaika—e hoʻemi ana i ke kaumaha o nā lako.
