Test Chinodiwa
Pamusoro pekuve nechokwadi chekuumbwa kwemakemikari uye michina zvivakwa, hydrostatic bvunzo inoitwa imwe neimwe, uye flaring uye flattening bvunzo dzinoitwa. . Pamusoro pezvo, pane zvimwe zvinodikanwa zveiyo microstructure, saizi yezviyo, uye decarburization layer yepombi yesimbi yakapedzwa.
Tensile Test:
1. Kune zvigadzirwa zvesimbi zvezvigadzirwa, mugadziri anofanirwa kuita bvunzo dzekusimba. Kune pombi yakashongedzerwa yemagetsi, inodzikwa pasarudzo yemugadziri, bvunzo dzekusimba dzinogona kuitwa pandiro yesimbi yaimbogadzira pombi kana kuti perfomred papombi yesimbi zvakananga. Muedzo wakaitwa pachigadzirwa unogona zvakare kushandiswa seyedzo yechigadzirwa.
2. Machubhu ebvunzo achasarudzwa zvisina tsarukano. Kana bvunzo dzakawanda dzichidikanwa, nzira yesampling inova nechokwadi chekuti sampuli dzakatorwa dzinogona kumiririra kutanga uye kupera kwekudziya kwekutenderera (kana zvichibvira) uye magumo ese echubhu. Kana bvunzo dzakawanda dzichidikanwa, patani ichatorwa kubva kumachubhu akasiyana kunze kwekunge yakakora chubhu sampu inogona kutorwa kubva kumativi ese echubhu.
3. Sampu yepombi isina musono inogona kutorwa pane chero chinzvimbo padenderedzwa repombi; iyo welded pombi sampu inofanira kutorwa inenge 90 ° kune weld seam, kana pane sarudzo yemugadziri. Samples inotorwa pane inenge kota yehupamhi hwe strip.
4. Hazvina mhosva kusati kwaitwa uye mushure mekuedza, kana muenzaniso wekugadzirira ukawanikwa usina kukwana kana kuti pane kushayikwa kwezvinhu zvisingakoshi kune chinangwa chekuedza, muenzaniso unogona kubviswa uye kuchinjwa nemumwe muenzaniso wakagadzirwa kubva muchubhu imwechete.
5. Kana bvunzo inomiririra bhechi rezvigadzirwa isingaite zvinodiwa, mugadziri anogona kutora mamwe machubhu matatu kubva mubhechi rimwe chete remachubhu kuti aongororwe zvakare.
Kana zvese zvakadzokororwa zvemasampuli zvikasangana nezvinodiwa, batch yemachubhu inokodzera kunze kwechubhu isina kukodzera iyo yakatanga kutorwa sample.
Kana inopfuura sampuli imwe yakatanga kutorwa kana imwe kana akawanda sample yekuongororazve isingaite zvinodiwa, mugadziri anogona kuongorora batch yemachubhu rimwe nerimwe.
Iyo yakarambwa batch yezvigadzirwa inogona kudziyisa uye kudzokororwa sebatch nyowani.
Flattening Test:
1. Muyedzo wemuenzaniso uchave mhete yekuyedza kana kupera kuchekwa isingasviki 63.5mm (2-1 / 2in).
2. Mienzaniso inogona kutemwa kusati kwaitwa kupisa, asi zvichienderana nekupisa kwekupisa kwakafanana sepombi inomiririrwa. Kana bvunzo yebatch ikashandiswa, matanho achatorwa kuona hukama pakati pemuenzaniso uye sampling chubhu. Choto chimwe nechimwe mubatch imwe neimwe inofanira kuputswa.
3. Mucherechedzo uchave wakatsetseka pakati pemahwendefa maviri akafanana. Museti yega yega yekupepeta bvunzo sampuli, imwe weld yakagadzikwa pa90 ° uye imwe yakatsetseka pa0 °. Iyo muenzaniso ichaitwa flatten kusvika chubhu madziro asangana. Pamberi pechinhambwe pakati pemahwendefa akaenzana pasi pemutengo wakatarwa, hapana kuputika kana kuputsika kunofanira kuonekwa mune chero chikamu chemuenzaniso. Munguva yese yekupfapfaidza maitiro, hapafanirwe kuve nekushata chimiro, welds asina kusanganiswa, delamination, simbi yekupisa, kana simbi extrusion.
4. Hazvina mhosva kusati kwaitwa uye mushure mekuedza, kana muenzaniso wekugadzirira ukawanikwa usina kukwana kana kuti pane kushayikwa kwezvinhu zvisingakoshi kune chinangwa chekuedza, muenzaniso unogona kubviswa uye kuchinjwa nemumwe muenzaniso wakagadzirwa kubva muchubhu imwechete.
5. Kana chero sampuli inomiririra chubhu isingasviki nezvinodiwa, mugadziri anogona kutora sampuli kubva kumagumo echubhu kuti awedzere kuongororwa kusvikira zvinodiwa zvasangana. Zvisinei, kureba kwepombi yakapedzwa mushure mekuenzanisa hakufaniri kuva pasi pe80% yehurefu hwepakutanga. Kana chero sample yechubhu inomiririra batch yezvigadzirwa ikasasangana nezvinodiwa, mugadziri anogona kutora maviri ekuwedzera machubhu kubva mubhechi rezvigadzirwa uye ocheka masampuli kuti aedzezve. Kana mhedzisiro yekudzokorodza iyi yese ikasangana nezvinodiwa, batch yemachubhu inokodzera kunze kwechubhu yakatanga kusarudzwa semuenzaniso. Kana imwe yemasampuli ekudzokorora ikasasangana nezvinodiwa, mugadziri anogona kuenzanisa machubhu asara ebhechi rimwe nerimwe. Pachisarudzo chemugadziri, chero batch yemachubhu inogona kupiswa zvakare uye kudzokororwa sechikamu chitsva chechubhu.
Impact Test:
1. Kune machubhu, seti yemasampuli ichatorwa kubva mujenya rega rega (kunze kwekunge maitiro akanyorwa akaratidzwa kusangana nezvinodiwa zvekutonga). Kana iyo kurongeka yakagadziriswa paA10 (SR16), kuedza kunosungirwa.
2. Kune casing, 3 mapaipi esimbi anofanirwa kutorwa kubva mubatch yega yega yekuyedza. Iwo machubhu ekuyedza achave akasarudzwa zvisina tsarukano, uye sampling nzira ichave nechokwadi chekuti samples dzakapihwa dzinogona kumiririra kutanga uye kupera kwekudziya kwekutenderera uye kumberi nekumashure kumagumo kweruoko panguva yekupisa kupisa.
3. Charpy V-notch impact test
4. Hazvina mhosva kusati kwaitwa uye mushure mekuedza, kana muenzaniso wekugadzirira ukawanikwa usina kukwana kana kuti pane kushayikwa kwezvinhu zvisingakoshi kune chinangwa chekuedza, muenzaniso unogona kubviswa uye kuchinjwa nemumwe muenzaniso wakagadzirwa kubva muchubhu imwechete. Mienzaniso haifanirwe kungonzi yakaremara nekuda kwekuti haizadzise huwandu hushoma hwesimba rinodiwa.
5. Kana mhedzisiro yeinopfuura imwe sample yakaderera pane yakaderera yakatorwa simba inodiwa, kana mhedzisiro yeimwe sample yakaderera pane 2/3 yeinotsanangurwa yakaderera yakatorwa simba inodiwa, matatu mamwe masampula achatorwa kubva pachimedu chimwe uye. retested. Simba rekukanganisa remuenzaniso wega wega wakaongororwazve richave rakakura kudarika kana kuenzana nediki rataurwa rinodiwa simba rakatorwa.
6. Kana mhedzisiro yeimwe ongororo isingaite zvinodiwa uye mamiriro ekuedza kutsva asina kusangana, saka matatu ekuwedzera masampuli anotorwa kubva kune imwe neimwe yezvimwe zvidimbu zvitatu zvebatch. Kana mamwe mamiriro ekuwedzera achizadzisa zvinodiwa, batch inokodzera kunze kweiyo yakakundikana pakutanga. Kana chinopfuura chimwe chekuwedzera chekuongorora chisingaenderane nezvinodiwa, mugadziri angasarudza kuongorora zvidimbu zvakasara zvebatch chimwe nechimwe, kana kudzoreredza batch uye kuiongorora mubatch nyowani.
7. Kana zvinopfuura chimwe chezvinhu zvitatu zvekutanga zvinodiwa kuratidza batch yezvidzidzo zvakarambwa, kuongororazve hakubvumirwi kuratidza kuti batch yemachubhu inokodzera. Mugadziri anogona kusarudza kuongorora mabhechi asara chidimbu nechidimbu, kana kudziya zvakare batch uye oiongorora mubatch nyowani..
Hydrostatic Test:
1. Pombi imwe neimwe ichaiswa pasi pe hydrostatic pressure test yepombi yose mushure mekukora (kana zvakakodzera) uye kurapwa kwekupedzisira kwekupisa (kana zvakakodzera), uye ichasvika kune yakatsanangurwa hydrostatic pressure pasina kubuda. Iyo yekuyedza yekumanikidza kubata nguva yakagadzirwa isingasviki 5s. Pamapombi akasungwa, mawedhi epombi anozotariswa kuti haabvisi here pasi pekumanikidzwa kwekuyedza. Kunze kwekunge kuyedzwa kwepombi kwese kwaitwa pachine nguva yekumanikidza kunodiwa kune yekupedzisira pombi mamiriro ekupedzisira, fekitori yekugadzira shinda inofanirwa kuita hydrostatic test (kana kuronga bvunzo yakadaro) papombi yese.
2. Mapaipi ekugadzirisa kupisa achaiswa pasi pe hydrostatic test mushure mekupedzisira kupisa kupisa. Kudzvanywa kwekuyedza kwemapombi ese ane tambo dzakarukwa kunenge kuri kuyedza kumanikidza kweshinda uye couplings.
3 .Mushure mekugadzirisa kusvika kuhukuru hwepombi yakapedzwa yakapera uye chero ipi zvayo inopisa-yakagadziriswa majoini mafupi, muedzo we hydrostatic uchaitwa mushure mekupedzisira kwepasi kana thread.
