Using G type Leeb hardness tester to test the hardness of low strength structural steel sheets, the hardness number is often lower.
针对用便携G型里氏硬度计对低强度钢板测试其硬度值偏低的现象 ,利用静载台式硬度计及动载里氏硬度计对高强度不锈钢板和低强度结构钢板进行了测试 ,并进行了对比分析。
Combining with the situation of existing error in hardness measurement by Leeb Hardness Tester,this paper introduces the measuring principle of leeb hardness tester and analyzes the influencing factors of measuring error such as surface roughness of specimen,specimen thickness and the distance between measuring points,and proposes some corresponding preventive measures.
结合基建现场利用里氏硬度计测量硬度过程中存在误差的情况,介绍里氏硬度计的测量原理,分析影响里氏硬度计测量误差的试件表面粗糙度、试件厚度和测量点的距离等因素,并提出相应的预防措施。
Using the cone anvil made by self, inspect the hardness of small steel ball on WELSON - A653T Rockwell hardness tester ,solve the problem of the small steel ball is slip on the pedestal anvil and "V" shape anvil, difficult to fix,and make the variance analysis to the result compare with traditional method,and to prove the result , of inspect by this way is correct.
在WELSON—A653T洛氏硬度计上,采用自制凹锥形砧座测试微小钢球的硬度,解决了微小钢球在常用平面砧座和V形砧座上易打滑,不易固定,致使压头打在砧座上,损坏压头和砧座的难题,并采用方差分析的方法,将该法与传统试验方法相比较,验证其检测结果与传统法所获检验结果无显著性差异。
The Rockwell hardness tester is a precision measurement instrument in material and part hardness testing, which is often used in detection of materials, product and half-finished product.
洛氏硬度计是检测材料和零件硬度较精密的计量仪器,用来测量材料或者成品半成品的相应硬度,其性能指标主要体现在检测精度和操控性两个方面。
