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 DEG 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.

摘要： Slow cooling zone for a steel annealing furnace consists of an atmosphere circulation device in a housing, an indirect heating device, a circulation conduit with cooler fitted into it and opening and closing valves to enable the effects of the coller to be used or to be cut off from the housing. When the steel is to be subjected to a quick reduction treatment the valves are closed and the heating device switched on. To switch back to a cooling zone, the heater is switched off and the valves opened. The heater is made up of a number of electric heaters.

摘要： A heat treatment furnace in which a metal strip to be treated W passes through heat exchange chambers 11 before reaching the zone 5 for heating and maintaining temperature. According to the invention the strip returns to the chambers 11 after it has been heated, so that fans can circulate gas against the two parts Wa, Wb of the strip and enable heat to be withdrawn from the hot strip and transmitted to the cold strip. Application to the furnaces for heat treatment of metal strips.

摘要： PURPOSE:To perform continuous heat treatment of a metallic strip with excellent thermal efficiency by passing the metallic strip through a continuous heat treating furnace from the preheating and precooling zone thereof to the heating and soaking zone thereof and further passing the strip back and forth in the preheating and precooling zone. CONSTITUTION:A heat treating furnace 2 to be used for subjecting continuously a long-sized metallic strip W to a heat treatment such as annealing or the like is segmented to a preheating and precooling zone 4 and a heating and soaking zone 5. The strip W is passed through a U-shaped conveying path P in the direction of arrow by an upsetting roll 13. The strip W is first preheated in the lower part of a preheating and precooling chamber 11 by the sensible heat of the heat- treated strip W passing in the upper part. The strip is then heated by a heater 18 in the lower heating chamber 8 of the zone 5 and is soaked in an upper soaking chamber 9 of the zone 5 by the roll 13. The lower metallic strip is again preheated thereafter by a heat exchange in the chamber 11 and the strip itself is precooled. The metallic strip is continuously heat-treated with high thermal efficiency without releasing the heat in the furnace to the outside.
