Title (EN) CONTINUOUS ANNEALING FURNACE
(FR) FOUR DE RECUIT CONTINU
(JA) 連続焼鈍炉
Abstract:
(EN) Provided is a continuous steel annealing furnace comprising a preheating zone, a heating zone, a soaking zone, and a cooling zone; the furnace having a cooling means such as a hearth roller cooling apparatus that cools by spraying cooling gas onto both axial ends of a hearth roller provided in the heating zone; the cooling means using atmospheric gas from the preheating zone as the cooling gas.
(FR) L'invention concerne un four de recuit continu d’acier comprenant une zone de préchauffage, une zone de chauffage, une zone de stabilisation thermique et une zone de refroidissement ; le four présente un moyen de refroidissement tel qu'un appareil de refroidissement de rouleau de sole qui refroidit un rouleau de sole par pulvérisation d’un gaz de refroidissement sur les deux extrémités axiales dudit rouleau situé dans la zone de chauffage ; le moyen de refroidissement utilise le gaz atmosphérique provenant de la zone de préchauffage comme gaz de refroidissement.
(JA) 予熱帯、加熱帯、均熱帯及び冷却帯を備えた鋼板の連続焼鈍炉であって、加熱帯に設けられたハースロールの軸方向両端部に冷却ガスを吹き付けて冷却するハースロール冷却装置などの冷却手段を有しており、冷却手段は、予熱帯の雰囲気ガスを冷却ガスとして用いる。
