Understanding the basics of green sand testing

Procedure - The green compressive strength of green sand is the maximum compressive stress that a mixture is capable of sustaining when prepared, rammed and broken under standard conditions The rammed cylindrical specimen (2 in diameter and 2 in long) is formed by placing a weighed amount of sand in a tube and ramming the sand three tim...

Which green sand properties should you control per molding ,

Mar 09, 2017· Composition of green sand molding mixture for iron foundries typically consists of 100 parts silica sand, 8 parts bentonite clay and other additions like carbon ( 0,3 parts ) or cereals and 3 % water content It’s called “ green” because the mold strength is developed with mechanical (compression) stress; not by a chemical reaction nor heat...
