X60 Mutsara Pipe, Mechanical Properties Of
X60 Mutsetse Pipe, Surface kupisa kurapwa kwakakamurwa kuita mapoka maviri, imwe ndeyemakemikari kupisa kurapwa, imwe ndeyekudzima kwepamusoro uye kupisa kupisa kurapwa, iyo yekuomarara nzira yekuyedza ndeyotevera:
[1] Chemical kupisa kurapwa kweX60 pombi
Kemikari kupisa kupisa ndeyekuita kuti pamusoro peX60 pombi chubhu ipinde muatomu imwe kana akati wandei emakemikari element, kuitira kuti ichinje chimiro chemakemikari, chimiro uye zvimiro zveX60 pipeline chubhu pamusoro.Mushure mekudzima uye kudziya kwakadzika tembiricha, pamusoro peX60 pombi pombi ine kuomarara kwakanyanya, kupfeka kuramba uye kubata kuneta simba, uye musimboti weX60 pombi pombi ine simba rakakura uye kuoma.
-- Iyo huru tekinoroji paramita yemakemikari kupisa kurapwa X60 pombi kudzika kweakaomeswa layer uye kuoma kwepasi.Kudzika kweakaomeswa layer kunofanirwa kuedzwa ne vickers hardness tester.Pima chinhambwe kubva paX60 pombi pamusoro kusvika painodonha kuoma kusvika pa50HRC.Uku ndiko kudzika kunoshanda kwekuomesa kemikari kupisa kwekurapa kweX60 pombi yehuku kuoma kwekuongorora uye kuomesa kwepasi kupisa kurapwa kuoma kweX60 pombi yechubhu yekuona, inogona kushandisa vickers kuomarara tester, pamusoro rockwell kuomarara tester kana rockwell kuomarara tester kuyedza, chete ukobvu hwe nitriding gobvu mutete, kazhinji isingapfuuri 0.7 mm, saka haichakwanise kushandisa rockwell kuomarara tester, Microhardness tester inogona kushandiswa.
[2] X60 pombi pamusoro pekudzima uye kupisa kupisa kurapwa
-- Kudzima kwepamusoro uye kupisa kupisa kurapwa kunowanzoitwa nekudziisa induction kana kupisa kwemurazvo.Iwo main tekinoroji paramita kuoma kwepasi, kuomarara kwenzvimbo uye kunoshanda kuomesa layer kudzika.Vickers hardness tester inogona kushandiswa pakuomarara kuyedza, rockwell kana pamusoro Rockwell kuomarara tester.Kusarudzwa kwesimba rekuedza (chiyero) kune hukama nehupamhi hwehusimba hwekuomesa uye kuomarara kwepaipi yeX60.Kune marudzi matatu emamita ekuoma anobatanidzwa.
Vickers hardness tester inzira yakakosha yekuyedza kuomarara kwepasi kwekupisa kwakagadziriswa X60 pombi pombi.Inogona kushandisa 0.5 ~ 100kg bvunzo simba kuyedza iyo nzvimbo yekuomarara seyakatetepa se0.05mm.Kururama kwaro ndiko kwepamusoro-soro, uye kunogona kusiyanisa zvishoma mutsauko wekuoma kwepasi kwekupisa kwakabatwa X60 pombi pombi.Pamusoro pezvo, kudzika kweiyo inoshanda kuomarara layer inoyerwawo ne vickers hardness tester, saka zvinodikanwa kugadzirira Vickers kuomarara tester kune mayuniti anoita kupisa kwepamusoro kurapwa kana kushandisa nhamba yakakura yepasi kupisa kupisa workpiece.
-- Surface Rockwell kuomarara tester zvakare yakanyatso kuyedza kuomarara kwepaipi yakaomeswa X60 pombi.Pane zviyero zvitatu zveiyo Rockwell hardness tester yekusarudza kubva.Inogona kuyedza akasiyana epamusoro akaomeswa X60 mitsetse ine inoshanda kuomesa kudzika kwakakura kupfuura 0.1mm.Kunyangwe iko kurongeka kweiyo Rockwell hardness tester haina kukwirisa sevickers hardness tester, inogona kusangana nezvinodiwa senzira yekuyedza yehutongi hwemhando uye kuongorora kuenderana muzvidyarwa zvekupisa kupisa.Uyezve, inewo hunhu hwekushanda kuri nyore, kushandiswa kuri nyore, mutengo wakaderera, kuyerwa nekukurumidza, uye inogona kuverenga zvakananga kukosha kwekuoma, nezvimwewo. Surface Rockwell kuomarara tester inogona kushandiswa kubhechi yekupisa kupisa kwepamusoro X60 pombi pombi nekukurumidza uye isiri- kuedza kunoparadza.Izvi zvakakosha zvikuru kune X60 pombi yekugadzirisa uye michina yekugadzira michina.
- Rockwell kuomarara tester inogona zvakare kushandiswa kana iyo yekumusoro yakaomeswa layer yakakora.Kana ukobvu hweakaomeswa dhizaini yekupisa kupisa iri 0.4 ~ 0.8mm, HRA chiyero chinogona kushandiswa, kana ukobvu hweakaomeswa dhizaini anopfuura 0.8mm, HRC chiyero chinogona kushandiswa.
-- Vickers, Rockwell uye Surface Rockwell huma hutsika hunogona kushandurwa zviri nyore kuita chiyero, kudhirowa kana mushandisi anodiwa kuomarara maitiro.Matafura ekushandura anoenderana anopiwa mune zvepasi rose zviyero ISO, American standard ASTM uye Chinese standard GB/T.
[3] Kurapa kwekupisa kwenzvimbo
-- Kana kuomarara kwenzvimbo kwezvikamu kuchidikanwa kuve kwakakwira, kurapa kwekudzima kupisa kwenzvimbo kunogona kuitwa nekudziisa induction nedzimwe nzira.Mapaipi epaipi eX60 akadaro anowanzoda kutara nzvimbo yekudzimisa kupisa kwenzvimbo uye kukosha kwehukukutu hwenzvimbo pakudhirowa.Kuomarara kuyedzwa kweX60 pombi kuchaitwa munzvimbo yakatarwa.Kuomarara kuyedza chiridzwa chinogona kushandisa Rockwell kuomarara muyedzo, kuyedza HRC kuomarara kukosha, senge kupisa kurapwa kuomeswa layer haina kudzika, inogona kushandisa pamusoro Rockwell kuomarara tester, bvunzo HRN kuomarara kukosha.
