Temperature Control of a Continuous, Push Type, Five Zone, Slab Reheating Furnace for Minimum Fuel Usage. Volume 1. Text and Appendix A

摘要

This report treats the reheat furnace used to heat slabs from the slabbing mill up to the rolling temperature for the hot strip mill. It determines the minimum fuel rates needed to achieve required outlet temperatures as a function of production rate. It also presents a scheme carrying out the transition from one steady state operating level to another with a near minimum of fuel usage. A method for using this transition scheme on a process control computer is also presented here. (ERA citation 11:005607)
