The need for control of raw materials is critical to the success of iron casting production from greensand systems. The effect of carbonaceous additives on casting quality was reviewed, the relationship and effect of sand grading, total carbon, volatiles and loss on ignition for sand quality stabilization were knew and controlled. Various control methods are examined; various predictive methods are looked at as a control feature as well. The quality of additives and their role and more importantly their interaction is highlighted. Also reviewed is the interpretation of results and the action required to ensure control and more importantly consistent quality castings from greensand systems with the emphasis on the understanding and control of carbonaceous additive on casting performance.
