Mea Hana Paa kila nui
Nā kikoʻī
ʻO ka laulā o ka lau he 500 ~ 1500 mm;ʻO ka laulā o ka mānoanoa he 600 ~ 3000 mm.Hoʻokaʻawaleʻia nā papa lahilahi e nāʻano kila, e like me ke kila maʻamau, ke kila kiʻekiʻe, ke kila kila, ke kila puna, ke kila kila, ke kila mea hana, ke kila wela, ke kila kila, ke kila silika a me kaʻoihana hao maʻemaʻe, a me nā mea'ē aʻe. hoʻohana, aia nā aila pahu me ka papa, enamel me ka papa, bulletproof me ka papa, etc. E like me ka ʻili o ka uhi wahi, aia nā galvanized pepa, tin pā, ke alakaʻi pā, plastic composite kila pā.Kiʻekiʻe wela, kiʻekiʻe kaomi, haʻahaʻa wela, corrosion kū'ē.
ʻO nā papa kila mānoanoa he ʻano like nō ia me nā papa lahilahi.Ma nā ʻano a pau, ma ka hoʻohui ʻana i ka pā alahaka, ka pā paila, ke kila kaʻa, ke kila ipu hao a me ka multilayer kiʻekiʻe kiʻekiʻe o ka ipu hao a me nā ʻano ʻē aʻe he pā mānoanoa, kekahi mau ʻano o ke kila e like me ka pā kila beam kaʻa (2.5 ~ 10 mm mānoanoa. ), pāpaʻi hoʻonaninani (2.5 ~ 8 mm mānoanoa), ke kila kila, ke kila wela a me nā ʻano ʻano like ʻole me ke keʻa lahilahi.
Eia kekahi, ua'ōleloʻia ke kila kila a me nā mea waiwai,ʻaʻole like nā papa kila a pau,ʻaʻole like ka mea, kahi i hoʻohanaʻia ai ke kila kila,ʻaʻole like.
Hoʻokaʻawale ʻana i nā kila kila
Wahi a ka ʻike o nā mea hoʻohui, hiki ke hoʻokaʻawale ʻia i:Ke kila kila haʻahaʻa (ʻoi aku ka liʻiliʻi o ka 5%), Ke kila kila waena (ka nui o nā mea hoʻohuihui 5% -10%), Ke kila kila kiʻekiʻe (ka nui o nā mea hoʻohuihui> 10%).
Wahi a nā mea hoʻohui nui, ua māhele ʻia lākou i:Ke kila Chromium (CR-Fe-C) Ke kila Chrome-Nickel (CR-Ni-Fe-C), Manganese (Mn - Fe - C), Silicon Manganese kila (Si-Mn-Fe-C).
E like me ka hana maʻamau a i ʻole ka hoʻokaʻawale ʻana o nā mea liʻiliʻi liʻiliʻi, hiki ke hoʻokaʻawale ʻia i:Ke kila Pearlitic, Ke kila Martensitic, Ke kila Ferritic, Austenitic kila, Ledeburite kila.
Ka hemahema o ka hao kalapona
(1) Haʻahaʻa paʻakikī.Ma keʻano holoʻokoʻa, ʻo 10mm-20mm wale nō ke anawaena quenching kiʻekiʻe o ka wai kalapona kila.
(2) Haʻahaʻa haʻahaʻa i ka ikaika a me ka buckling.No ka laʻana, ʻo ka σ S o ke kila kalapona maʻamau Q235 kila he 235MPa, aʻo ka σ S o ke kila kila haʻahaʻa 16Mn ʻoi aku ma mua o 360MPa.ʻO ka σ S / σ B o 40 kila he 0.43 wale nō, ʻoi aku ka haʻahaʻa ma mua o ke kila kila.
(3) Paʻa maikaʻi ʻole ka hoʻoheheʻe ʻana.Ma muli o ka ilihune tempering paʻa, kalapona kila i ka quenching a me ka tempering lapaʻau, i mea e hōʻoiaʻiʻo kiʻekiʻe ikaika e hoʻohana i ka haʻahaʻa tempering wela, i ka toughness o ke kila ua haʻahaʻa;I mea e hōʻoiaʻiʻo ai i ka ʻoi aku ka paʻakikī, ʻoi aku ka haʻahaʻa o ka ikaika o ka wela wela, no laila ʻaʻole kiʻekiʻe nā waiwai mechanical piha o ke kila kalapona.
(4) ʻAʻole hiki ke hoʻokō i nā koi o ka hana kūikawā.ʻO ke kila kalapona i loko o ka oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic a me nā mea'ē aʻe he pinepineʻilihune, hikiʻole ke hoʻokō i nā pono o ka hana kūikawā.
