Abstract
PURPOSE:To heat to the specified temperature with a minimum of fuel, without causing insufficient combustion, by determining the heating curve when the object sensible heat is larger than the balance of the charge heat minus loss heat on the basis of the value at such time, when heating the object in a heating furnace. CONSTITUTION:When a heating furnace is divided into several bands, the furnace staying time on the whole is distributed into each band. In a certain band, when the heating object sensible heat Q2 is smaller than the balance of the charge heat Q1 minus loss heat Q3, the temperature rise curve of the heating object is determined from the total heat absorption rate. In other band, when Q2 is larger than the remainder of Q1 minus Q3, the product of the difference of Q1 and Q3 and the furnace staying time in that band is regarded as the object sensible heat increment to determine the heating curve of the object. The temperature of the object at the furnace outlet may be determined from this heating curve. By prolonging the furnace staying time gradually, the furnace staying time at the point where the temperature of the object at the furnace outlet reaches the intended heating temperature is the most efficient heating furnace staying time.
