What percentage of clay content is required in furan-no-bake system?
What percentage of powered ferrosilicon is mixed with sodium silicate bonded sand in Nishiyama process?
In dielectric core baker, several metallic plates are used for supporting the cores in the system
Dielectric core bakers are faster in operation and have good control of maintaining the temperature.
For small cores mass production, dielectric core bakers can be preferred over continuous type ovens used for baking cores.
After baking of cores in dielectric core bakers, they can be directly used in the moulding box.
Core finishing also includes a coating of refractory materials on cores to protect them.
It is not possible to bake dry sand cores by dielectric core bakers.
How much percentage of water or moisture is contained by green sand cores?
