Which of the following core cannot be classified under the shape and position of the core?
View Answer Explanation
Which of the following cores are produced by mixing silica?
In resin bond cores, the core is baked at what temperature?
In hot box process, core box is heated up to what temperature?
Sodium silicate reacts with carbon dioxide to give what?
Silica gel is formed when sodium bicarbonate reacts with carbon monoxide.
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.
