钢的临界点试验误差补充报告本文根据[81]冶标字第2202号文件及“钢的临界点测试及误差分析”专题会的要求,进行了不同位置放置热电偶及不同升温速度对钢临界点测试结果影响的试验。结果表明,将热电偶放在试样内(中心孔)较将热电偶放于试样表面测得的临界点低,慢速升温较快速升温测得的临界点低。因此必须统一测试方法,才可得到能相互比较的数据。 According to the [81] Sword Zi No. 2202 documents and “steel critical point test and error analysis,” the topic of the meeting will be carried out at different locations of the thermocouple and different heating rate of steel critical Point test results affect the test. The results show that the thermocouple placed in the sample (center hole) than the thermocouple placed on the surface of the sample measured the critical point is low, slow heating temperature faster than the measured critical point low. Therefore, we must unify the test methods in order to get the data that can be compared with each other.
