Abstract
PURPOSE: To improve heat efficiency and productivity of annealing equipment, by raising the temp. of exhaust gas of heating zone with combustion exhaust gas, etc., then utilizing it for preheating steel strip in its continuous annealing equipment.
CONSTITUTION: Steel strip is preheated, then heated and annealed in reducing atmosphere by a radiant tube 1 at continuous annealing of steel strip. Since temp. of exhaust gas exhausted from the tube 1 is low as 300W500°C, it is introduced to a combustion furnace 10 through a duct 9. A fuel 11 and an air 12 preheated at a preheater 19 are burnt by a burner 13 at the furnace 10 and sent as 700W1,100°C high temp. combustion gas to a heat exchanger 14 together with exhaust gas from a duct 9 to heat and supply heating medium to hollow rolls 17-1W17-n for preheating steel strip to the vicinity of annealing temp. at heating zone, and exhaust gas from the exchanger 14 is utilized for preheating combustion air for the furnace 10. heat efficiency including to heating zone after preheating is markedly improved and productivity of continuous annealing is improved.
