Kushandiswa kwesimbi isina tsvina

Kuoma

Stainless simbi chubhu inowanzoshandiswa brinell, Rockwell, Vickers matatu kuoma zviratidzo kuyera kuoma kwayo.

Brinell kuoma

Mune Stainless simbi chubhu mwero, kuomarara kwebrinell ndiyo inonyanya kushandiswa, kazhinji kune indentation dhayamita kuratidza kuoma kwezvinhu, zvese zviri zviviri intuitive uye nyore.Zvisinei, haikodzeri pombi dzesimbi dzakaoma kana dzakatetepa.

Rockwell kuoma

Iyo Rockwell kuomarara bvunzo yestainless simbi chubhu yakafanana nebrinell kuomarara bvunzo, inova iyo indentation bvunzo nzira.Musiyano ndewekuti inoyera kudzika kweiyo indentation.Rockwell kuomarara bvunzo inzira inoshandiswa zvakanyanya parizvino, pakati peiyo HRC yechipiri chete kune Brinell kuomarara HB mune simbi pombi standard.Rockwell kuomarara kunogona kuiswa kuti itarise kubva kune yakapfava kusvika kune yakaoma kwazvo simbi zvinhu, inogadzira iyo Brinell nzira haisi, iri nyore pane brinell nzira, inogona kubva yakananga kubva kune yakaoma muchina dial kuverenga kuomarara kukosha.Nekudaro, nekuda kwediki indentation, kukosha kwekuomarara hakuna kururama senge nzira yebuchwald.

Vickers kuoma

Stainless simbi chubhu Vickers kuomarara bvunzo zvakare indentation bvunzo nzira, inogona kushandiswa kuona kuomarara kwezvinhu zvakatetepa zvesimbi uye pamusoro.Iyo ine mabhenefiti makuru eBrinell neRockwell nzira uye inokunda zvipingamupinyi zvavo zvakakosha, asi haisi nyore senzira dzeRockwell uye haiwanzo shandiswa mumiyero yesimbi pombi.

Kuedza kuoma

Iyo dhayamita yemukati yepombi yesimbi isina tsvina inopfuura 6.0mm, uye ukobvu hwemadziro huri pasi pe13mm.Iyo annealed Stainless simbi pombi inogona kuedzwa neW-B75 Type Wechsler hardness tester.Iyo inokurumidza uye yakapusa, uye inokodzera kukurumidza uye nondestructive kuongororwa kwepombi yesimbi isina tsvina.Stainless simbi pombi yemukati dhayamita yakakura kupfuura 30mm, ukobvu hwemadziro hwakakura kupfuura 1.2mm simbi isina pombi, rockwell kuomarara tester, bvunzo HRB, HRC kuoma.Machubhu esimbi asina simbi ane dhayamita yemukati yakakura kupfuura 30mm uye ukobvu hwemadziro husingasviki 1.2mm akaedzwa kuoma kweHRT kana HRN nepamusoro Rockwell kuomarara tester.Kune mapaipi esimbi isina tsvina ane dhayamita yemukati isingasviki 0mm uye yakakura kupfuura 4.8mm, rockwell kuomarara tester inoshandiswa kuyedza kuomarara kweHR15T.Kana iyo yemukati dhayamita yepombi yesimbi isina simbi yakakura kupfuura 26mm, unogona zvakare kushandisa Rockwell kana pamusoro Rockwell kuomarara tester kuyedza kuoma kwemukati memadziro epombi.

Kuvandudzwa kwesimbi isina tsvina

Migumo yose miviri yechikamu chekuvhura uye chegomba, uye kureba kwayo uye chikamu chechikamu chesimbi yakakura, inogona kunzi simbi pombi.Kana kureba uye chikamu chechikamu chekuenzanisa chiri chidiki, chinogona kunzi chikamu chepombi kana pombi fittings, zvese ndezvechikamu chezvigadzirwa zvepombi.

Kwemakore anopfuura 60, vagadziri vezvivakwa vanga vachishandisa simbi isina tsvina kuvaka zvivakwa zvechigarire zvinodhura.Zvivakwa zvakawanda zviripo zvinonyatsoratidza kururama kwechisarudzo ichi.Zvimwe zvakashongedzwa chaizvo, zvakadai seChrysler Building muNew York City.Asi mune mamwe akawanda maapplication, simbi isina tsvina inoita basa risinganyanyi kukosha asi rakakosha mukunaka uye kuita kwezvivakwa.Simbi isina simbi, semuenzaniso, ndiyo inosarudzwa nevagadziri vanovaka nzira dzemumativi munzvimbo dzine vanhu vakawanda nekuti inoshingirira kubvongodzwa uye kunyungudika kupfuura mamwe simbi dzakakura zvakafanana.

Simbi isina tsvina yakashandiswa sechinhu chekugadzirisa kuvaka kwezvivakwa zvitsva uye kudzoreredzwa kwenzvimbo dzenhoroondo kwemakore anopfuura 70.Magadzirirwo ekutanga aive akavakirwa pamisimboti yekutanga yekuverengera.Nhasi, dhizaini dhizaini, senge ANSI/ASCE-8-90 "Design Code yeCold-formed Stainless Steel Structural Parts" standard uye "Structural Stainless Steel Design Manual" yakadhindwa pamwe chete neNiDI neEuro Inox, yakarerutsa dhizaini. hupenyu hurefu, zvakachengetwa zvakanaka zvikamu zvezvivakwa zvezvivakwa.

Stainless simbi kunze kwenyika chikamu chakakosha chehupfumi hweChina kunze kwenyika, inoita basa rakakosha mukukurudzira kukura kwehupfumi hweChina, asi kubva mumamiriro ezvinhu aripo ekutengeserana neChina kunze kwesimbi isina simbi, kutengeswa kwesimbi kweChina kwakasangana nekupikisa kukuru.

Kubva gore rapfuura, mhiri kwemakungwa kwaiwanzouya kune zvigadzirwa zvekukanda simbi muChina "double reverse" meseji, ine simba guru kune indasitiri yesimbi isina tsvina muChina, uye kutengeswa kunze kwenyika chikamu chakanaka chekusimudzira indasitiri yesimbi munyika yedu. , mukusimudzira indasitiri ine chikamu chikuru chemusika, pamberi pekuderera kwehupfumi, kukurumidza kwekusimudzira kunonoka, Stainless simbi indasitiri yekusimudzira munyika yedu inofanirwa kuramba ichivandudza mhando yechigadzirwa, zvirinani kusimudzira kwekutengeserana mhiri kwemakungwa uye kurwisa kuchengetedzwa kwekutengeserana, zvigadzirwa uye kuchengetedzwa kwezvakatipoteredza, zviwanikwa zvesimba, nharaunda yevanhu, inosimudzira kukwikwidza kwezvigadzirwa zvesimbi isina tsvina, nenzira iyi chete inogona nzvimbo isingagoneki mukutengeserana kwekunze.
