过去,我们对大型、重型、异形零件的硬度测定都采用肖氐硬度计,但其硬度值正确性差、示值变动范围大,难以正确反映零件硬度,因此,国内外科技界都在研制结构新颖、性能可靠的轻便硬度计,以代替肖氐硬度计。我厂在苏州市计量测试所的倡导下,研制成功HRJ-150轻便式多角度洛氐硬度计.去年九月,在江苏、上海、南京、青岛、长春、浙江等省市计量部门参加的全国性鉴定会上一致认为该硬度计设计合理,技术指标达到设计要求,符合国家对金属洛氐硬度测试方法的有关规定,并具有体积小、重量轻、外形美观、操作方便、适应性强等特点.该硬度计主机重量仅8公斤,除了可进行常规硬度测试外,
In the past, we used the hardness of the large, heavy and shaped parts Xiaoqia hardness tester, but the hardness value of the correctness of the poor, showing a wide range of changes, it is difficult to accurately reflect the hardness of the parts, therefore, the domestic and international scientific and technological community are developing a new structure , Reliable performance of portable hardness tester to replace the Shaw hardness tester. I plant in Suzhou City, under the initiative of the measurement test, the successful development of HRJ-150 portable multi-angle Luozuo hardness. Last September, in Jiangsu, Shanghai, Nanjing, Qingdao, Changchun, Zhejiang and other provinces and municipalities to participate in the measurement department At the meeting of the sex appraisal meeting, it was unanimously agreed that the design of the hardness meter is reasonable and the technical indexes meet the design requirements. It conforms to the relevant regulations of the country on the test method of hardness of the metal Luohu and has the characteristics of small size, light weight, beautiful appearance, convenient operation and strong adaptability . The hardness of the host weight of only 8 kg, in addition to the conventional hardness test,
