Summary

In a program to demonstrate capability for manufacturing FRCI 40–20 billets, Martin Marietta Denver Aerospace fabricated 24 billets in a laboratory setting. The fabrication rate was paced by the 24-h billet firing cycle. With four firings weekly, four billets were produced per week with a manpower expenditure of 15 h per billet. By firing two billets at a time, five times a week, fabrication could be increased to ten billets weekly with a reduction in manpower cost to 10.4 h per billet. Based on use of a single V-blender and one casting tower, but assuming sufficient capacity to fire all felts produced in one 8-h day, production could be stepped up to 60 billets per five-day week. Manpower cost would be cut to 4.7 h per billet.
