ndi masikelo ena 15;
Mitundu iwiriyi ya Khalid Hardness Yester mu Njira yogwirira ntchito, njira yoyeserera, ndipo molingana ndi magetsi, moyenera
Kugwiritsa ntchito pulasitiki hard dyentna:
Choyenera kwa pulasitiki, zolimba zamiyala, zopanga zingwe, zitsulo zokhala ndi chitsulo, aluminiyam tinloy, makatoni ndi zinthu zina zolimbika.
Ma sikelo akuluakulu: hre, hrl, hrrr;
Mitundu Yoyenerera: 70-100hre, 50-115hrl, 50-115hrm, 5055rr;
Pali mitundu itatu yayikulu yolimbana ndi pulasitiki yovuta, motero: Steel mpira undenter: 1/8 ", 1/4", 1/2;
Gulu Loyesererana: Chovala chapulasitiki molingana ndi digiri yazomwe zimatha kugawanika: Njira yowerengera: Maudindo ndi Magetsi Akuyimba Mafoni, Kuwonetsera digito ndi Kuyimba Kosangalatsa;
Miyezo yoyeserera ya anthu wamba, kuphatikizapo American Converder Standard Astme D785 Zapamwamba, Zochitika Padziko Lonse Lapansi Iso2039 za mapulaneti, ndi Chinese Strewboll Standard GEB / T3398.2, J3998.2, JBS7409 YA PLOVE.
HRA - yoyenera kuyesa kuuma kwa zinthu zolimba kapena zopyapyala, monga carbide, kumatchinga chitsulo, chouma chouma, zitsulo zolimba, etc.
HRB- yoyenera kuyezetsa zida zamitundu, monga chapakati komanso pansi kaboni atayaka, zitsulo zoponyera chitsulo, zitsulo zosiyanasiyana komanso ma brangumin ambiri pambuyo pochita ndi kulanda.
HRC -Siuts yoyesa chitsulo cha kaboni, chitsulo chachitsulo pambuyo pakuthana ndi kutentha kwa kutentha, komanso zoyesa zokoka chitsulo, zitsulo zotupa zimaponya chitsulo.
Hrd- yoyenera kukanikiza pang'ono pakati pa zinthu zosiyanasiyana, monga kutentha kutentha kwapadera kunalimbikitsa chitsulo cha Pearlite.
Kuyenera kuyesa kuyesa chitsulo, aluminiyamu alnoy, magnesium alloy, zokhala ndi chitsulo ndi zitsulo zina zofewa.
HRF - yovomerezeka yamkuwa, mkuwa wofiira, General Aluminium Smoy, etc.
HRH- yoyenera pa zitsulo zofewa monga aluminiyamu, zinc ndikutsogolera.
