Iron Rust puts you in charge of a steel strip pickling and phosphating line. Balance acid concentration, bath temperature and line speed so the rust scale comes off exactly clean without etching the base steel. Rinse, condition, phosphate, passivate and dry each coil, then get paid by cleanliness times film consistency.
Manage iron build-up in the acid bath with timely regeneration, rotate through orders of different plate thickness and rust grades, and invest your coins in six real upgrades: auto acid pump, steam coil, iron analyzer, inhibitor formula, hot air dryer and regeneration tower.
Simple to run, hard to master. How clean is your steel?
