Abstract:
(EN) The present invention provides an annealing device which comprises at least one section and in which the at least one section is filled with a gas constituting a non-reducing atmosphere or a weakly reducing atmosphere, as well as a device for producing plated steel sheet comprising the annealing device, and a method for producing plated steel sheet by means of such a device. The invention can substantially improve the quality of plating onto hot-dipped steel sheet, including the plating properties, alloying properties, anti-pickup properties, plating adhesion properties, anti-flaking properties, anti-cratering properties and anti-ash properties, by using prior-art annealing equipment and heat-treatment cycle without any additional oxidation-reduction heat treatment process or large quantities of high-cost alloying elements. Further, the present invention is advantageous in that it allows outstanding quality to be ensured economically and easily, and in that it has various applications and reduces costs.
(FR) La présente invention concerne, d'une part un dispositif de recuit qui comprend au moins une zone et dans lequel, la zone considérée est remplie d'un gaz constituant une atmosphère non réductrice ou une atmosphère faiblement réductrice, d'autre part un dispositif permettant la production d'une tôle d'acier plaqué comprenant le dispositif de recuit, et enfin un procédé permettant de produire de la tôle d'acier plaqué au moyen d'un tel dispositif. L'invention permet d'améliorer sensiblement la qualité du plaquage appliqué au bain chaud sur la tôle d'acier, notamment en ce qui concerne les propriétés du plaquage, les propriétés de réalisation d'alliage, les propriétés d'anti-prise, les propriétés d'adhésion du plaquage, les propriétés d'anti-écaillage, les propriétés de résistance à la formation des cratères, et les propriétés de résistance à la calcination, par utilisation d'équipement de recuit selon l'état de la technique et d'un cycle de traitement thermique sans employer ni traitement thermique additionnel d'oxydoréduction ni de grandes quantités d'éléments de formation d'alliages coûteux. L'invention se distingue par la possibilité qu'elle procure de réaliser facilement et de façon économique une tôle d'acier plaqué de qualité exceptionnelle, par ses diverses applications, et par le fait qu'elle permet une réduction des coûts.
(KO) 1 이상의 섹션을 포함하며, 상기 1 이상의 섹션에 비환원성 분위기 또는 약환원성 분위기의 가스가 충진된 소둔장치 및 상기 소둔장치가 포함된 도금강판의 제조장치 및 이러한 장치를 통해 도금강판을 제조하는 방법이 제공된다. 추가적인 산화-환원 열처리 공정이나 고가의 합금 원소를 다량으로 포함하지 않아도 기존의 소둔 설비 및 열처리 사이클을 이용하여 용융도금 강판에 대한 도금성, 합금화성, 내픽업성, 도금밀착성, 내플레이킹성(Anti-flaking), 내크레이터성(Anti-crater), 내애쉬성(Anti-ash)등의 도금 품질을 대폭 향상시킬 수 있다. 또한 우수한 품질을 경제적이고 용이하게 확보할 수 있어 그 용도가 다양하며 비용 절감 측면에서 효과적이다.
