The influence of chromite sand on the dimensional accuracy of castings
Chromium ore sand has good fire resistance, thermal conductivity and other properties, which can reduce the temperature gradient and internal stress of castings, help prevent hot cracks and deformation of castings, and thus improve the dimensional accuracy of castings to a certain extent. However, factors such as the particle size of chromite sand may also affect the dimensional accuracy. If the particle size is too coarse, it may affect the accuracy to a certain extent,
