1) Kodi choyesa cholimba cha Rockwell chingagwiritsidwe ntchito kuyesa kuuma kwa khoma la chitoliro chachitsulo?
Zinthu zoyeserera ndi chitoliro chachitsulo cha SA-213M T22 chokhala ndi mainchesi akunja a 16mm ndi makulidwe a khoma la 1.65mm. Zotsatira za mayeso a Rockwell kuuma mayeso ndi motere: Pambuyo kuchotsa oxide sikelo ndi decarburization wosanjikiza pamwamba pa chitsanzo ndi chopukusira, chitsanzo amaikidwa pa workbench V woboola pakati, ndi HRS-150S digito Rockwell kuuma tester ntchito kuyesa mwachindunji kuuma Rockwell pamwamba pake ndi katundu wa 980.7N. Pambuyo pa mayesowo, zitha kuwoneka kuti khoma la chitoliro chachitsulo lili ndi kupindika pang'ono, ndipo zotsatira zake ndikuti kuuma kwa Rockwell kuyeza kumakhala kotsika kwambiri, zomwe zimapangitsa kuyesa kolakwika.
Malinga ndi GB/T 230.1-2018 «Metallic Materials Rockwell Hardness Test Part 1: Test Method», kulimba kwa Rockwell ndi 80HRBW ndipo makulidwe ocheperako 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. Panthawi yoyesedwa, popeza palibe chithandizo pakati pa chitsanzocho, chimayambitsa kuwonongeka pang'ono (komwe sikungathe kuwonedwa ndi maso), kotero kuti kuuma kwa Rockwell kwenikweni kumakhala kochepa.
2) Momwe mungasankhire choyezera kuuma kwa mapaipi achitsulo:
Pambuyo pa mayesero ambiri pa kuuma pamwamba pa mipope zitsulo, kampani yathu yafika pa mfundo zotsatirazi:
1. Mukamayesa kuuma kwa Rockwell kapena kuyesa kuuma kwa Rockwell pamwamba pa mipope yachitsulo yokhala ndi mipanda yopyapyala, kuthandizira kosakwanira kwa khoma la chitoliro kumayambitsa kusinthika kwa chithunzicho ndikupangitsa zotsatira zotsika;
2. Ngati chithandizo cha cylindrical chikuwonjezeredwa pakati pa chitoliro chachitsulo chokhala ndi mipanda yopyapyala, zotsatira zoyesazo zidzakhala zochepa chifukwa olamulira a mutu woponderezedwa ndi kayendetsedwe ka katundu sangatsimikizidwe kuti ndi perpendicular pamwamba pa chitoliro chachitsulo, ndipo pali kusiyana pakati pa kunja kwa chitoliro chachitsulo ndi chothandizira chopangidwa ndi cylindrical.
3. Njira yosinthira kuuma kwa Vickers kuyeza ku kuuma kwa Rockwell pambuyo pakuyika ndi kupukuta chitsanzo cha chitoliro chachitsulo ndi cholondola.
4. Pambuyo kuchotsa oxide sikelo ndi decarburization wosanjikiza pamwamba pa chitoliro zitsulo ndi machining ndege mayeso padziko akunja ndi inlaying izo, pamwamba Rockwell kuuma amasandulika Rockwell kuuma, amene ali ndi zolondola.
