Global economic crisis is affecting steel industry. Savings in the production line is one way for reducing the impact. This paper is discussing how to examine the balance of the production line that consists of 3 different types of machines in a Billet Steel Plant, Krakatau Steel Indonesia using Promodel. Simulation is very helpful in determining alternative solutions because of the uncertain processing time in the third machine. Results of the simulation model will be processed and optimized using SimRunner. The result of this research indicates that the balance of the production line in Billet Steel Plant depends on the downtime machine in Electric Arc Furnace (EAF). After experimenting some alternatives, the recommended delay-time for each EAF Machine as follow: 51 minutes for EAF-1; 56 minutes for EAF-2; and 87 minutes for EAF 3. The saving of this recommendation as the result of simulation process is about Rp. 14.104.531/hour.
