Fives Stein offers a wide range of concrete solutions:
From the simple equipment: one single reheat furnace feeding a wire mill
To the most complex processes: up to four furnaces of different types (pusher or walking beam) and capacities feeding the same hot strip mill.
Our physical models have proven their reliability and stability over the last 30 years with continuous improvements.
H.O.T. Heating Operator Terminal, a user-friendly and efficient software specially developed for batch production.
H.O.S. Heating Optimization System, heating optimisation system for complex processes including the active pacing to optimise the product heating temperature control and discharging sequence, particularly when several furnaces of different production capacities are feeding the same mill.
Our models use the latest technological innovations based on Fuzzy Logic:
Either to improve the process response time by a direct action on the proportional and integral parameters of the loop temperature controllers for each furnace zone
and/or to improve the longitudinal temperature profile on the product by acting on the flame length.
More than 150 reheat furnaces are equipped with Fives Stein process optimisation systems, including:
40 hot strip mills
12 plate mills
50 wire and section mills
