Abstract
We newly developed and established the high efficiency continuous reheating furnace with low thermal inertia in the Kimitsu plate mill, in order to adopt to the needs for perfect HCR (Hot Charged Rolling), TMCP (Thermo Mechanical Control Process), and energy conservation.
Through the adoption of ceramic fiber as lining material for the furnace body, skids, partition walls and heat cover plates over the hearth opening, this furnace realizes low thermal inertia and reinforcement of thermal insulation, and also makes heating schedule free.
In adition, by adopting high turn down burners, cyclic combustion control and a, high precision temperature calculation model, this furnace is superior in relation to slab temperature with the high precision uniformity.
