SLAB WIDTH SETTING METHOD FOR A HEATING FURNACE TO ENABLE WIDTH CONTROL WITH IMPROVED PRECISION

摘要

PURPOSE: A slab width setting method for a heating furnace is provided to determine flat and taper slabs and insertion of the slabs by using indicated and measured values selectively, thereby improving precision in width control.;CONSTITUTION: A slab width setting method for a heating furnace comprises the steps of: determining flat slab and taper slab depending on selected indicated and measured width systems(S20), setting the respective slab width depending on the determination of the taper slab and the flat slab(S50), and determining and processing unavailability of slab depending on the set slab width, wherein the indicated width system is automatically selected, if the measured width system applies, and then a difference over a predetermined value between the measured width system and the indicated width system is maintained over a predetermined time.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) Indicated width system; (CC) Measured width system; (DD) End; (S10) Selecting a width system; (S20) Indicated width system or measured width system?; (S30) Applying the indicated width system; (S40) Applying the measured width system; (S50) Outputting a set slab width
