ʻO kapahū slurryhe pamu e lawe ana i ka huikau o na mea paa a me ka wai. No laila, e abrasive ka mea waena i nā ʻāpana kahe o ka slurry pump. No laila, pono e hana ʻia nā ʻāpana kahe o ka slurry pump i nā mea ʻaʻahu.

Hoʻokaʻawale ʻia nā mea metala maʻamau no nā pulu slurry i ka hao, ka hao ductile, ka hao chromium kiʻekiʻe, ke kila kila, a pēlā aku. ʻO ka hao hao chromium kiʻekiʻe ke kolu o ka hanauna o nā mea ʻaʻahu-pale i kūkulu ʻia ma hope o ka hao keʻokeʻo maʻamau a me ka hao nickel paʻakikī. Ma muli o nā hiʻohiʻona o ke ʻano o ka hao chromium kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ka paʻakikī, ʻoi aku ka ikaika o ka wela, ka pale ʻana i ka wela, a me ke kūpaʻa ʻana ma mua o ka hao maʻamau. Ua hoʻomaikaʻi ʻia ka hao hao chromium kiʻekiʻe e like me ka mea anti-abrasive maikaʻi loa i ka wā o kēia wā, a ua hoʻohana nui ʻia i kēlā me kēia lā.

ʻO ke kūlana aupuni o Kina no ka hao keʻokeʻo keʻokeʻo kūʻokoʻa (GB/T8263) e kuhikuhi ana i ka papa, haku mele, paʻakikī, kaʻina hana wela, a me nā ʻano hoʻohana o ka hao keʻokeʻo chromium kiʻekiʻe.

ʻO ke kūlana hoʻokō no ka hao chromium kiʻekiʻe ma United States ʻo ASTMA532M, United Kingdom BS4844, Kelemānia DIN1695, a me Farani NFA32401. Ua hoʻomohala ʻo Rūsia i ka 12-15% Cr, 3-5.5% Mn a me 200mm pā mānoanoa pōleʻa wili wili i ka Soviet Union mua, a ke hoʻokō nei i ka maʻamau ҐOCT7769.

ʻO nā mea nui i hoʻohana ʻia no nā ʻāpana kahe o nā paila slurry ma ka home a me nā ʻāina ʻē he kila kila, hao chromium kiʻekiʻe, a me ka hao nickel paʻakikī. ʻO ka hao chromium kiʻekiʻe kahi mea moho kūpono no nā ʻāpana kahe o nā pamu slurry. Ma o ka hoʻoponopono ʻana a i ʻole ke koho ʻana i nā pae ʻike kalapona a me ka chromium, hiki ke loaʻa nā hopena hoʻohana maikaʻi loa o nā ʻāpana kahe ma lalo o nā kūlana ʻoihana a me nā ʻoihana mining.

ʻO ka hao chromium kiʻekiʻe ka pōkole o ke kiʻekiʻe chromium keʻokeʻo anti-wear cast iron. He mea anti-wear me ka hana maikaʻi loa a me ka nānā kūikawā; ʻoi aku ka kiʻekiʻe o ka pale ʻana ma mua o ke kila kila a ʻoi aku ka paʻakikī a me ka ikaika ma mua o ka hao keʻokeʻo maʻamau. I ka manawa like, he kūpaʻa maikaʻi hoʻi ia i ka wela kiʻekiʻe a me ka corrosion, i hui pū ʻia me ka hana maʻalahi a me ke kumukūʻai maʻalahi, a ʻike ʻia ʻo ia kekahi o nā mea anti-abrasive maikaʻi loa i kēia manawa.

I kēia manawa, hoʻohana maʻamau ʻia kahi ʻano o nā mea hoʻoheheʻe chromium kiʻekiʻe.

ʻO nā paila slurry i hana ʻia me A05 (Cr26) mea i hoʻohana nui ʻia i ka ʻoihana mining. Hōʻike ka microstructure o ke kiʻekiʻe chromium alloy A05 i loko o nā karbides chromium eutectic paʻakikī i loko o kahi matrix kahua marten paʻakikī. Ma nā noi pahū slurry kahi i ʻoi aku ka abrasive a me ka corrosive akā ʻo ka abrasion, ʻoi aku ka maikaʻi o ka hana o kēia mea ma mua o nā hao keʻokeʻo ʻē aʻe.

ʻOiai ʻo nā ʻāpana pulu i hana ʻia me A07 (Cr15Mo3) he kiʻekiʻe ke kūpaʻa o ka lole, ʻoi aku ka paʻakikī, a ʻoi aku ka lōʻihi o ka lawelawe ʻana ma mua o A05, ʻelua ko lākou kumukūʻai ma mua o A05, no laila ʻoi aku ka haʻahaʻa o ke kumukūʻai a ʻoi aku ka liʻiliʻi o ka hoʻohana.

ʻO A49 (Cr30) he hao keʻokeʻo keʻokeʻo chromium kiʻekiʻe. He hypoeutectic ka microstructure a loaʻa nā carbide chromium eutectic i loko o kahi matrix austenite/martensite. ʻOi aku ka haʻahaʻa o ke kalapona o ka chromium A49 kiʻekiʻe ma mua o ka chromium A05 kiʻekiʻe. Nui aʻe ka chromium i loko o ka matrix. I loko o kahi kaiapuni ha'aha'a ha'aha'a, 'oi aku ka nui o ke kūpa'a o ka chromium A49 ma mua o ka chromium A05.

I kēia manawa, ʻo nā mea i ʻōlelo ʻia ma luna nei nā mea metala i hoʻohana mau ʻia i lokomea hoʻolako pauma slurry. E like me ke ʻano o ka mea lawe ʻia, e koho mākou i ka mea kūpono loa.
