Investigation of the effects of bentonite and water on the thermophysical properties and gasifying power of a moist mould. The quality of moulded products is related to that of the mould because the latter is the source of many defects such as porosity, blowholes, etc.… The formation of gaseous defects in the moulded products is generated by gas penetration into the parts and this happens during the formation of the first crust of solidified metal. Thus, the problem of defects due to gas penetration must be addressed in order to suppress the responsible factors. Our investigation aimed at determining the influence of bentonite and water on the thermophysical properties (such as thermal conductivity, effusivity, specific heat and diffusivity) and the gasifying power of a green moulding sand in order to obtain a good moulded product. The consequence of our results is to propose a new mixture. |
