Momwe mungasankhire choyesera kuuma poyesa zitsanzo za mawonekedwe a tubular

1) Kodi choyesera kuuma kwa Rockwell chingagwiritsidwe ntchito kuyesa kuuma kwa khoma la chitoliro chachitsulo?

Zipangizo zoyesera ndi chitoliro chachitsulo cha SA-213M T22 chokhala ndi mainchesi akunja a 16mm ndi makulidwe a khoma a 1.65mm. Zotsatira za mayeso a Rockwell hardness tester ndi izi: Pambuyo pochotsa oxide ndi wosanjikiza wochotsedwa pa sampuli pamwamba ndi chopukusira, chitsanzocho chinayikidwa patebulo logwirira ntchito looneka ngati V ndipo mayeso a Rockwell hardness adachitika mwachindunji pamwamba pake, pogwiritsa ntchito HRS-150S digital display Rockwell hardness tester pa katundu:980.7N.

Pambuyo pa mayeso, zitha kuwoneka kuti chitoliro chachitsulo chomwe chili pakhoma chili ndi kusintha pang'ono, ndipo zotsatira zake ndi izi: mtengo wotsika woyesedwa wa kuuma kwa Rockwell umapangitsa mayesowo kukhala osavomerezeka.

Malinga ndi GB/T 230.1-2018 « Mayeso a Rockwell Hardness a zinthu zachitsulo Gawo 1: Njira zoyesera », kuuma kwa Rockwell ndi 80HRBW ndipo makulidwe ochepera a chitsanzo ndi 1.5mm. Kukhuthala kwa chitsanzo Nambala 1 ndi 1.65mm, makulidwe a wosanjikiza wochotsedwa ndi 0.15~0.20mm, ndipo makulidwe a chitsanzo mutachotsa wosanjikiza wochotsedwa ndi 1.4~1.45mm, womwe uli pafupi ndi makulidwe ochepera a chitsanzo omwe atchulidwa mu GB/T 230.1-2018.

Pa nthawi yoyeserera, chifukwa chakuti malo oyesera sathandizidwa, izi zingayambitse kusintha pang'ono (mwina kosaoneka ndi maso), kotero mtengo woyesedwa wa kuuma kwa Rockwell ndi wotsika kwambiri.

2) Momwe mungasankhire zinthu zapamwambaRockwellchoyesera kuuma poyesa mapaipi achitsulo：

Kampani yathu yayesa mobwerezabwereza kuuma kwa pamwamba pa chitoliro chachitsulo ndipo yafika pamalingaliro otsatirawa.：

Mayeso okhwima a Rockwell kapena mayeso okhwima a Rockwell pamwamba pa chitoliro chachitsulo chokhala ndi makoma owonda. Kusakwanira kwa khoma kungayambitse kusintha kwa zitsanzo ndikupangitsa zotsatira zochepa za mayeso;

Ngati chothandizira chozungulira chiyike pakati pa chubu chachitsulo chopyapyala, chifukwa sichingatsimikizire kuti mzere wolunjika ndi njira yokwezera katundu ndi pamwamba pa chitoliro chachitsulo zili mopingasa pamwamba, ndi pamwamba pa chitoliro chachitsulo ndipo pamenepo padzayambitsa kusiyana kwa chothandizira chozungulira cha kusiyana pakati pa pamwamba pa chitoliro chachitsulo ndi pamwamba pa chothandizira chozungulira, zidzapangitsanso kuti zotsatira za mayeso zikhale zochepa.

Sinthani mayeso a kuuma kwa Vickers kukhala mayeso a kuuma kwa Rockwell mutapukuta chitoliro chachitsulo, mudzapeza mtengo wolondola wa kuuma kwa Rockwell.

2. Mukachotsa wosanjikiza wa oxide ndi decarburization pamwamba pa chitoliro chachitsulo ndikukonza ndege yoyesera pamwamba pake ndikuyiyika mkati, Mtengo umakhala wolondola kwambiri poyerekeza ndi Superficial Rockwell hardness tester ndi Rockwell hardness tester.
