Slab, billet, or bloom reheat trials, measuring stock temperature for comparison to mathematical model data, take time and effort to prepare and run. Due to the ferocious heat of the furnace, the data logger, which gathers and stores the temperature data from the test slab, must be well protected. The EagleOne EO-TB07 achieves the task of offering maximum protection for an extended period to cope with stoppages in the furnace (roll changes etc.) while the trial is under way.
