    摘要: A vertical bright-annealing furnace 1 for metal strips includes a muffle-type heating station 12, a refractory-type heating station 13. The refractory-type heating station 13 includes a shell 24 lined with a heat-insulating material 26 and a second heater 27. These two stations 12 and 13 are connected to one another by a flexible connecting unit 14 which is extensible in the longitudinal direction of the heating zone. A metal strip S conveyed in the furnace 1 is heated in the muffle-type heating station 12 and subsequently heated in the refractory-type heating station 13 up to a predetermined temperature, for example, about 1,100.degree. C. According to this constitution, a large-sized vertical annealing furnace may be constructed. Also, the period of durability of the muffle may be extended, the running expenses may be decreased, and metal strip having good brightness may be produced.
