Abstract： The steel anvil is an important measuring instrument in the rate test of the rebound instrument， and whether its value is accurate or not is related to whether the rebound instrument is qualified or not， thus affecting the detection of the compressive strength of concrete and other building materials. In this paper， through the study of the working principle and calibration method of steel anvil， the measurement model of steel anvil is established， and the measurement uncertainty of its measurement parameters is evaluated， which provides a reference for the research of steel anvil calibration.

Keywords： steel anvil; rebound instrument; measurement model; calibration method; uncertainty evaluation
