1.Kusimba simba (σb): Iyo yakanyanya simba (Fb) iyo sampuli inowira mukukakavadzana kana ichidhonzwa, yakakamurwa nekushushikana (σ) kunowanikwa kubva kune yekutanga-chikamu-chikamu nharaunda (So) yemuenzaniso, inonzi tensile simba. σb), muN/mm2 (MPa).Inomiririra huwandu hwepamusoro hwesimbi yesimbi kuti irambe kukanganisa pasi pekukakavadzana.Ipo: Fb - simba guru remuenzaniso rinomira kana radhonzwa, N (Newton);Saka - iyo yepakutanga-yakayambuka-chikamu nzvimbo yemuenzaniso, mm2.
2.goho point (σs): zvinhu zvesimbi zvine chiitiko chegoho, kushushikana apo iyo muenzaniso inogona kuramba ichirebesa pasina kuwedzera kwesimba (ramba uripo) panguva yekutambanudza, inonzi iyo goho point.Kana simba rikadzikira, mapoinzi epamusoro uye epasi egoho anofanirwa kusiyaniswa.Iyo unit yegoho poindi iN/mm2 (MPa).Yepamusoro yegoho poindi (σsu): iyo yakanyanya kushushikana pamberi peiyo specimen goho uye simba rinotanga kuderera;Yakaderera goho poindi (σsl): iyo shoma kushushikana muchikamu chekubereka kana yekutanga yenguva pfupi mhedzisiro isingaverengeki.Ikoko: Fs - simba rekukohwa (nguva dzose) yemuenzaniso mukukakavadzana, N (Newton) Saka - yepakutanga-chikamu chechikamu chechikamu chemuenzaniso, mm2.
3.Elongation mushure mekupwanyika: (σ) Muchiyedzo chetensile, chikamu chekuwedzera kwehurefu hwemuenzaniso mushure mekudhonza chikero chayo kusvika pakureba kwechiyero chekutanga chinonzi kureba.Inoratidzwa mu σ, iyo unit ndeye%.Ikoko: L1 - kureba kwemuenzaniso mushure mokunge mufananidzo wacho wadhonzwa, mm;L0 - kureba kweiyo specimen yekutanga pitch, mm.
4.Fractional shrinkage: (ψ) Mumuyedzo wetensile, iyo yakanyanya shrinkage yemuchinjiko-sectional nzvimbo pa shrinkage yayo mushure meiyo specimen yabviswa sechikamu chepakati chepakutanga-chikamu chechikamu chinonzi shrinkage.Inoratidzwa se ψ, mu%.Ikoko: S0 - nzvimbo yepakutanga yemuchinjikwa-chikamu chemuenzaniso, mm2;S1 - iyo shoma-yepakati-chikamu nharaunda pane shrinkage mushure memuenzaniso wabviswa, mm2.
5.Hardness index: kugona kwesimbi kuramba kupinza chinhu chakaoma kupinda pamusoro, chinonzi kuomarara.Zvichienderana nebvunzo nzira uye chiyero chekushandisa, kuomarara kunogona kukamurwa kuita Brinell kuomarara, Rockwell kuomarara, Vickers kuomarara, Shore kuoma, microhardness uye yakakwirira tembiricha kuoma.Kune iyo chubhu inowanzo shandiswa muBrinell, Rockwell, Vickers kuomarara matatu.
Brinell kuomarara (HB): Uchishandisa simbi kana bhora recarbide reimwe dhayamita, dzvanya iro rakatarwa bvunzo simba (F) mukati meiyo sampuli, bvisa simba rekuyedza mushure menguva yakatarwa yekubata, uye kuyera iyo indentation dhayamita (L) pamusoro pemuenzaniso.The Brinell hardness value ndiyo quotient inowanikwa nekupatsanura test force by spherical surface area ye indentation.Inoratidzwa seHBS (bhora resimbi) muN/mm2 (MPa).
Hot-dip galvanized simbi pombi dzinoshandiswa zvakanyanya mukuvaka, michina, migodhi yemarasha, indasitiri yemakemikari, magetsi emagetsi, mota dzenjanji, indasitiri yemotokari, migwagwa mikuru, mabhiriji, midziyo, zvivakwa zvemitambo, michina yekurima, michina yepetroleum, michina yekutsvaga uye mamwe maindasitiri ekugadzira. .
Galvanized steel pombi ipombi yesimbi yakasungwa ine dip inopisa kana electro galvanized surface.Galvanization inogona kuwedzera kushorwa kwepombi dzesimbi uye kuwedzera hupenyu hwesevhisi.Pombi yesimbi ine mashandisirwo akasiyana siyana, pamusoro pekushandiswa sepombi yezvinwiwa zvakaderera zvakaita semvura, gasi neoiri, inoshandiswawo sepombi yemafuta uye pombi yemafuta muindasitiri yepetroleum, kunyanya iyo minda yemafuta emugungwa, sehita yemafuta, inotonhorera inotonhorera uye marasha distillation uye mafuta ekugezesa exchanger yemakemikari coking michina, uye senge pombi yekutsigira pombi yemapombi etrestle nemakomba emigodhi, nezvimwe.
Pombi yemvura, pombi yemafuta, pombi yekugezera, fenzi yemugwagwa mukuru, chivharo chekudurura, nezvimwe.
