Abstract EN
Sand casting is the most widely used casting technique, known for ages, even since ancient times.
The main goal of this study was to determine the thermal decomposition behaviour of foundry sand for cast steel.
We first tested the basic properties of foundry sand, including its proximate analysis, chemical composition, and particle size characteristics; we next monitored the thermal decomposition behaviour of foundry sand for cast steel via simultaneous thermal analysis.
We focused on the mass loss of foundry sand for cast steel at different heating rates in nitrogen and air atmospheres.
We adopted a novel method to calculate the volatile release characteristic index of foundry sand.
The volatile content of foundry sand for cast steel was very low, so the volatile release characteristic index of the sand could not be strictly calculated according to this concept.
We calculated the thermal decomposition kinetics parameters of foundry sand, namely, the activation energy and preexponential factor, under kinetics theory.
To thoroughly test the fitting effect, we conducted a single-factor analysis of variance on the source of error.
The results showed that the independent variable has a significant influence on the dependent variable and that the fitting equation we selected is feasible and effective.
