Plate Type Heating Apparatus for Continuous Annealing Furnace having The Same

摘要

A flat plate heater and a continuous annealing furnace having the same are provided.;The flat plate heating apparatus of the present invention includes a hot plate means having a vacuum inside and filled with a phase change material, an electric heat fin means for providing heat transfer while being provided on an outer side of the hot plate means, and adjacent to the electric heat fin means. Comprising a combustion means arranged in the, wherein the continuous annealing furnace, including the annealing furnace body through which the continuous steel sheet continuously passes in a multi-loop form, and the plate-type heating device installed in the longitudinal direction of the annealing furnace body, The internal space of the annealing furnace body is divided into an annealing chamber in which annealing of the combustion chamber and the continuous steel sheet is performed by the wall means of the heating apparatus.;Such a flat plate heating apparatus of the present invention not only increases the heating efficiency of the continuous steel sheet but also increases the heating efficiency, and stabilizes the combustion system of the heating apparatus and the continuous annealing furnace, and in particular, independently of the combustion chamber of the continuous annealing furnace. In the construction, a heating device, which is a flat plate type heat transfer medium, is installed between the combustion chamber and the annealing chamber through which the continuous steel sheet passes, so that smooth heat exchange between the heat transfer medium and the continuous steel sheet is achieved, thereby improving the annealing quality of the entire steel sheet.;Continuous steel sheet, continuous annealing furnace, flat plate heating device, combustion chamber, annealing chamber
