Brinell kuuma (HB) ndi awiri ena a mipira zitsulo kapena tungsten carbide mipira, mbamuikha mu chitsanzo pamwamba pa anakonzeratu mayeso mphamvu (F), pambuyo anaikiratu kugwira nthawi pambuyo mphamvu dontho mayeso, m'mimba mwake wa muyeso chitsanzo pamwamba indentation. (L).Brinell hardness test force yogawidwa ndi indentation spherical surface area quotient.Ku HBS (Mpira Mpira Mpira) unit N/mm2 (MPa).Chilinganizo ndi: kumene: F - mbande mu zitsulo pamwamba pa chitsanzo mphamvu mayeso, N;D - kuyesa zitsulo mpira awiri, mm;d - indentation avareji awiri mm.Kulimba kwa brinell kunayesedwa molondola komanso kodalirika, koma kawirikawiri HBS imangogwira 450N/mm2 (MPa) kapena kucheperapo kwa chitsulo, pazitsulo zolimba kwambiri, kapena pepala lopyapyala NA.Zitsulo mfundo, Brinell kuuma ndi ambiri ankagwiritsa ntchito, ndipo nthawi zambiri ankanena kuti kuuma zinthu, m'mimba mwake indentation d zonse mwachilengedwe ndi yabwino.
Brinell kuuma ndi njira zomwe zimagwiritsidwa ntchito kwambiri pakuyesa kuuma kwa chitoliro cha kaboni, .Njirayi imagwiritsa ntchito koyambirira, chifukwa cha kusindikiza kwake, motero kuuma kwa zinthu zomwe zimakhudzidwa ndi zosakaniza zamagulu a microsegregation m'njira zosiyanasiyana, zotsatira za mayeso zimawaza pang'ono, kuberekana bwino, zitha kuwonetsa kuuma kwa zinthuzo.
Mfundo: Mu mphamvu yodziwikiratu yodziwiratu, m'mimba mwake ya mpira wachitsulo umakanikizidwa pamwamba pa chitsanzo kuti ikhalebe nthawi, ndiyeno kuchotsa mphamvu yomwe yadziwika, kupanikizika kwa m'mimba mwake muyeso pamwamba pa chitsanzo, kungathe kuwerengedwa kutengera m'mimba mwake wa kukakamizidwa imprint kukakamiza chizindikiro malo gravure.Brinell hardness test force yogawidwa ndi indentation spherical surface area quotient.Gawo 9.807N/mm.The indentation Mpira waukulu wachitsulo woponderezedwa muzinthu zakuya, zotsika zolimba;mosemphanitsa kuuma mfundo kuchita.
