Brinell hardness scale

Muedzo wekuoma kweBrinell wakagadzirwa nainjiniya wekuSweden Johan August Brinell muna 1900 uye yakatanga kushandiswa kuyera kuoma kwesimbi.
(1)HB10/3000
①Eyedzo nzira uye musimboti: Bhora resimbi rine dhayamita ye10 mm rinotsikirirwa mukati mechinhu chepamusoro pasi pemutoro we3000 kg, uye dhayamita yemukati inoyerwa kuverenga kukosha kwekuoma.
②Inoshanda mhando dzemhando: Inokodzera kuomarara simbi zvinhu zvakaita sesimbi yakakandwa, simbi yakaoma, inorema alloys, nezvimwe.
③Mamiriro ekushandisa akajairwa: Kuyedzwa kwezvinhu zvemichina inorema nemidziyo. Kuomarara kuyedzwa kweakakura makuru uye forgings. Kudzora kwemhando muinjiniya nekugadzira.
④Zvinhu uye zvakanakira: Yakakura mutoro: Inokodzera zvinhu zvakakora uye zvakaoma, inogona kumirisana nekumanikidzwa kukuru, uye ive nechokwadi chekuyera mhedzisiro. Durability: Iyo simbi bhora indenter ine yakakwirira durability uye yakakodzera kwenguva refu uye inodzokororwa kushandiswa. Yakasiyana-siyana yekushandiswa: Inokwanisa kuyedza dzakasiyana siyana dzakaoma simbi zvinhu.
⑤ Zvinyorwa kana zvisingakwanisi: Sample size: Sample yakakura inodiwa kuti uone kuti indentation yakakura zvakakwana uye yakaringana, uye pamusoro peiyo sampuli inofanira kunge yakadzikama uye yakachena. Zvinodiwa zvePamusoro: Iyo yepamusoro inofanirwa kuve yakatsetseka uye isina tsvina kuti ive nechokwadi chekuyera kwechiyero. Equipment gadziriso: Midziyo yacho inoda kuverengerwa uye kuchengetedzwa nguva nenguva kuti ive nechokwadi chechokwadi uye kudzokorora kwebvunzo.
(2)HB5/750
①Edza nzira uye musimboti: Shandisa bhora resimbi rine dhayamita ye5 mm kudzvanya mukati mechinhu chepamusoro pasi pemutoro we750 kg, uye kuyera dhayamita remukati kuti uverenge kukosha kwekuoma.
②Anoshanda mhando dzemhando: Inoshanda kune simbi zvinhu zvine kuomarara kwepakati, senge alloys emhangura, aruminiyamu alloys, uye yepakati kuomarara simbi. ③ Mamiriro ekushandisa akajairika: Kudzora kwemhando yepakati kuoma kwesimbi zvinhu. Tsvagiridzo yezvinyorwa uye kusimudzira uye kuyedzwa kwema laboratori. Kuedzwa kwekuoma kwezvinhu panguva yekugadzira uye kugadzirisa. ④ Zvimiro uye zvakanakira: Mutoro wepakati: Inoshanda kune zvigadzirwa zvine kuomarara kwepakati uye inogona kunyatso kuyera kuoma kwavo. Flexible application: Inoshanda kune akasiyana epakati kuomarara zvinhu zvine simba kuchinjika. High repeatability: Inopa yakagadzikana uye inowirirana kuyerwa mhinduro.
⑥Zvinyorwa kana zvinogumira: Sample kugadzirira: Iyo sampuli yepasi inoda kuve yakati sandara uye yakachena kuti ive nechokwadi chechokwadi chechiyero chemhedzisiro. Zvinhu zvinogumira: Kune zvakapfava zvakanyanya kana zvakanyanya kuoma zvinhu, dzimwe dzakakodzera kuomarara nzira dzekuyedza dzingada kusarudzwa. Equipment gadziriso: Midziyo inoda kuverengerwa uye kuchengetedzwa nguva nenguva kuti ive nechokwadi chechokwadi uye kuvimbika kwechiyero.
(3)HB2.5/187.5
①Edza nzira uye musimboti: Shandisa bhora resimbi rine dhayamita ye2.5 mm kudzvanya mukati mechinhu chiri pasi pemutoro we187.5 kg, uye kuyera dhayamita rekupinza kuverenga kukosha kwekuoma.
②Inoshanda mhando dzezvinhu: Inoshanda kune yakapfava simbi zvinhu uye mamwe akapfava alloys, akadai sealuminium, lead alloy, uye simbi yakapfava.
③Mamiriro ekushandisa akajairwa: Kudzora kwemhando yezvinhu zvakapfava zvesimbi. Kuyedzwa kwezvinhu mumagetsi uye maindasitiri emagetsi. Kuomarara kuyedzwa kwezvinhu zvinyoro panguva yekugadzira uye kugadzirisa.
④Zvinhu uye zvakanakira: Yakaderera mutoro: Inoshanda kune zvakapfava zvinhu kudzivirira yakawandisa indentation. High repeatability: Inopa yakagadzikana uye inowirirana kuyerwa mhinduro. Yakasiyana-siyana yekushandisa: Inokwanisa kuyedza dzakasiyana siyana dzakapfava simbi zvinhu.
⑤ Zvinyorwa kana zvisingakwanisi: Sample kugadzirira: Sample surface inoda kuve yakati sandara uye yakachena kuti ive nechokwadi chechokwadi chemhedzisiro yekuyera. Zvinhu zvinogumira: Zvemidziyo yakaoma kwazvo, zvingave zvakafanira kusarudza dzimwe dzakakodzera kuomarara nzira dzekuyedza. Equipment gadziriso: Zvishandiso zvinoda kuverengerwa uye kuchengetedzwa nguva nenguva kuti ive nechokwadi chekuyera uye kuvimbika.
