Momwe mungasankhire choyesa kuuma poyesa zitsanzo za mawonekedwe a tubular

1) Kodi Rockwell kuuma tester angagwiritsidwe ntchito kuyesa kuuma kwa chitsulo chitoliro khoma?

Zinthu mayeso ndi SA-213M T22 zitsulo chitoliro ndi awiri akunja 16mm ndi makulidwe khoma 1.65mm. Zotsatira za mayeso a Rockwell kuuma tester ndi motere : Pambuyo kuchotsa okusayidi ndi decarburized wosanjikiza pa chitsanzo pamwamba ndi chopukusira, chitsanzo anaikidwa pa tebulo V woboola pakati ntchito ndi Rockwell kuuma mayeso anachitidwa mwachindunji pamwamba pa ake akunja, ntchito HRS-150S digito anasonyeza Rockwell kuuma Tester pa katundu .980.

Pambuyo pa kuyesedwa, zikhoza kuwoneka kuti chitoliro chachitsulo pakhoma chimakhala ndi kusintha pang'ono, ndipo zotsatira zake ndi : mtengo wochepa woyezera kuuma kwa Rockwell umapangitsa kuti mayesowo akhale opanda pake.

Malinga ndi GB/T 230.1-2018 « Rockwell Hardness test for metallic materials Gawo 1: Njira zoyesera », kulimba kwa Rockwell ndi 80HRBW ndipo makulidwe ochepa a chitsanzo ndi 1.5mm. The makulidwe a chitsanzo No.1 ndi 1.65mm, makulidwe a wosanjikiza decarburized ndi 0.15 ~ 0.20mm, ndi makulidwe a chitsanzo pambuyo kuchotsa wosanjikiza decarburized ndi 1.4 ~ 1.45mm, amene ali pafupi ndi makulidwe osachepera chitsanzo chotchulidwa GB/T 230.1-2018.

Pakuyezetsa, chifukwa chachitsanzo chapakati sichimathandizidwa, zingayambitse kusinthika (mwina wosawoneka ndi maso), kotero kuuma kwa Rockwell kuyeza mtengo kumakhala kotsika.

2) Momwe mungasankhire zachiphamasoRockwellhardness tester poyesa mapaipi achitsulo:

Kampani yathu yayesa mobwerezabwereza kuuma kwa chitoliro chachitsulo ndikufikira zotsatirazi:

Kuyesa kwapamwamba kwa Rockwell kuuma kapena kuyesa kuuma kwa Rockwell pamwamba pa chitoliro chachitsulo chokhala ndi mipanda yopyapyala. Thandizo losakwanira pakhoma lidzayambitsa kusinthika kwa chitsanzo ndikupangitsa zotsatira zochepa zoyesa;

Ngati kuika cylindrical thandizo pakati woonda-khoma zitsulo chubu, chifukwa sangathe kuonetsetsa kuti indenter olamulira ndi katundu Mumakonda malangizo ndi pamwamba pa chitoliro zitsulo perpendicular kumtunda, ndi kunja kwa chitoliro zitsulo ndipo padzachititsa kusiyana kwa cylindrical thandizo la kusiyana pakati pa zozungulira pamwamba pa chitoliro zitsulo ndi chifukwa otsika thandizo pamwamba pa chitoliro ndi cylindrical.

Sinthani kuyesa kuuma kwa Vickers kukhala kuyesa kuuma kwa Rockwell mutatha kupukuta choyikapo chachitsulo chachitsulo, mupeza mtengo wolondola wa kuuma kwa Rockwell.

2. Pambuyo kuchotsa okusayidi ndi decarburization wosanjikiza pamwamba pa chitoliro zitsulo ndi machining ndege mayeso padziko akunja ndi inlaying izo, Phindu ndi yolondola kwambiri poyerekeza Superficial Rockwell kuuma woyesa ndi Rockwell kuuma tester.
