8. Why are core prints added to the patterns when cores are used? a) They provide different cooling rates to the core b) They provide support to the cores and strength to the mould and core itself c) They are used to ease the removal of a core d) They are used to manufacture cores View Answer
The main constituents of the core sand are pure silica sand and a binder. Silica sand is preferred because of its high refractoriness. For higher values of permeability sands with coarse grain size distribution are used. The main purpose of the core binder is to hold the grains together, impart strength and sufficient degree collapsibility ...
