Ungakukhetha kanjani umhloli wobulukhuni wokuhlola amasampula we-tubular?

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

Izinto zokuhlola yipayipi lensimbi elinensimbi enobubanzi obungaphandle be-16mm kanye nodonga olungu-1.65mm. Imiphumela yokuhlolwa kwe-Rocwell Hardeness Test ima kanjena: Ngemuva kokususa isikali se-oxide kanye nongqimba wesampula ngaphezulu kwe-grinder, kanye ne-HRS-150s digital rockull testness isetshenziselwa ukuhlolisisa ubulukhuni be-RocKwell endaweni yakwa-980.7n. Ngemuva kokuhlolwa, kungabonakala ukuthi udonga lwensimbi yensimbi lunokushintshana kwensimbi okuncane, futhi umphumela uba yilokho i-Rocwell Halven Valual inani elilinganisiwe liphansi kakhulu, okuphumela ekuhlolweni okungalungile.

Ngokusho kwe-GB / T 230.1-2018 «Metallic Materials Rocwell Hurness Test Ingxenye 1: Indlela yokuhlola», Ubulukhuni be-RocKwell lungu-80hrbw kanye nobukhulu besampula obuncane bungu-1.5mm. Ubukhulu besampula uNombolo 1 ngu-1.65mm, ukushuba kwesendlalelo se-decorrubulised kungu-0,15 Ngesikhathi sokuhlolwa, ngoba akukho ukwesekwa enkabeni yesampula, kuzodala ukuthi kuguqulwe kancane (okungenzeka kungabhekwa yiso elinqunu), ngakho-ke i-Rocwell Hardness Value yangempela iphansi.

2) Ungakhetha kanjani umhloli we-Ravice Hardeness wamapayipi wensimbi:

Ngemuva kokuhlolwa okuningi ngobulukhuni bezinwele zamapayipi ensimbi, inkampani yethu ifike kulezo ziphetho ezilandelayo:

1. Lapho uqhuba i-Surfar Rocwell Hardness Test noma i-Rocwell Hurness test ebusweni bamapayipi ensimbi omncane, ukusekelwa okunganele kodonga lwepayipi kuzodala ukuguqulwa kwe-specimen futhi kuholele emiphumeleni yokuhlola ephansi;

2. Uma ukwesekwa kwe-cylindrical kufakwa maphakathi nepayipi lensimbi elidonswe ngesandla

I-3. Indlela yokuguqula ubulukhuni bama-hicker olulinganisiwe ukuze buhambise ubulukhuni ngemuva kokungena futhi uphungeli isampula lensimbi yensimbi linembile.

4. Ngemuva kokususa isikali se-oxide kanye ne-decrarruburization ungqimba ngaphezulu kwepayipi lensimbi kanye nemishini yendiza yokuhlola endaweni yangaphandle futhi uyisebenzisa, ubulukhuni be-surval Rocwell luguqulwa lube bulukhuni, olunembile.
