Ungayikhetha kanjani umhloli wobulukhuni wokuhlola amasampula we-tubular Hubulal

1) Ngabe i-RocKwell Hurneness Tenter isetshenziselwe ukuhlola ubulukhuni bodonga lwensimbi yensimbi?

Izinto zokuhlola yi-SA-213M T22 ipayipi lensimbi elinobubanzi obungaphandle bungu-16mm nodonga olungu-1.65mm. Imiphumela yokuhlolwa kwe-Rocwell Hurneness Tesser imi ngale ndlela elandelayo: Ngemuva kokususa i-oxide kanye ne-decorseburing ungqimba etafuleni lomsebenzi, kusetshenziswa i-HRS-150s Digital Display RocKwell Hartness Tesser emthwalweni: 980.7N.

Ngemuva kokuhlolwa, kungabonakala ukuthi ipayipi lensimbi odongeni linokushintshana okuncane, futhi umphumela uwukuthi: inani eliphansi elinganiselwa kubulukhuni be-RocKwell lenza ukuba kuhlolwe kungasebenzi kahle.

Ngokusho kwe-GB / T 230.1-2018 «RocKwell Hardeness Test for Metallic Materials Ingxenye 1: Izindlela Zokuhlola», Ubulukhuni be-Rocwell », ubukhulu be-RocKwell yi-80hrbw kanye nobukhulu obuncane be-specimen yi-1.5mm. Ubukhulu besampula uNo.1 ngu-1.65mm, ukushuba kwesendlalelo seDemorburised kungu-0,15 ~ 0.20mm, kanye nobukhulu besampula ngemuva kokususa ungqimba olubi lwesampula ku-GB / T300.1018.

Ngesikhathi sokuhlolwa, ngenxa yesikhungo sesampula asisekelwa, kuzodala ukucaca (kungenzeka kungabonakali ngamehlo anqunu) deformation, ngakho-ke i-Rocwell Hardness elilinganisiwe iphansi.

2) Ungayikhetha kanjani i-superficialBhofumbaumhloli we-hardness wokuhlola amapayipi ensimbi:

Inkampani yethu ihlole kaningi ubulukhuni bepayipi lensimbi futhi yafinyelela eziphethweni ezilandelayo:

I-Superfaic Rocwell Hardness Test noma i-Roclell Hundness Test ebusweni bepayipi lensimbi elidonswe ngawo. Ukwesekwa okunganele kodonga kuzodala ukonakala okucacisiwe futhi kuholele emiphumeleni yokuhlola ephansi;

Uma ubeka ukwesekwa kwe-cylindrical maphakathi ne-tube yensimbi emincane, ngoba akunakuqinisekisa ukuthi i-axis ye-Indenter kanye nokulayisha ipayipi lensimbi futhi kuzodala igebe lokusekelwa kwensimbi

Guqula ubuqili bokuvikeleka buvivinya ukuvikeleka kobulukhuni be-Rockwell ngemuva kokupholisa i-Steel Pipe Sampling Inset, kuzothola inani elinembile lobuqili.

2. Ngemuva kokususa i-oxide kanye ne-decorralization ungqimba ngaphezulu kwepayipi lensimbi kanye nemishini yendiza yokuhlola endaweni yangaphandle bese uyifaka umhloli wobulukhuni obulula ngokuqhathaniswa ne-Rocwell Hurnenness Tester.
