Title (EN) HOT-DIP PLATING METHOD AND APPARATUS AND PROTECTIVE MATERIAL
(FR) PROCEDE ET APPAREIL DE REVETEMENT METALLIQUE PAR PLONGE A CHAUD, ET MATERIAU DE PROTECTION
Abstract: front page image
(EN)A hot-dip plating method and apparatus in which a material to be plated is immersed in a hot-dipping bath after a protective material coating is applied on portions not to be hot-dipped of the material to be plated by the hot-dipping, and also relates to a protective material adapted to be used in the above-mentioned method. According to the invention, single-side plated steel strips are sufficiently protected by the application of the protective material coating which is superior in protecting performance and in adhesion, on the portions not to be hot-dipped of the material to be plated by the hot-dipping. More particularly, a coating consisting of soot or the like which is composed of carbon or mainly composed of carbon is firstly applied onto the portions not to be hot-dipped of the material (10) to be plated by the following hot-dipping said soot or the like being produced through incomplete combustion of fuel by means of a burner (52) installed in a snout (50). Then, the material to be plated is entirely immersed in a hot-dipping bath (22) and further cooled down by a cooler (7O). Finally, the protective material coating is removed by a brushing roller (26).
(FR)Procede et appareil de revetement metallique par plonge a chaud, dans lequel une piece a recouvrir est immergee dans un bain de plonge a chaud apres qu"un materiau de protection ait ete depose sur les parties de la piece qui ne sont pas destinees a etre recouvertes, et materiau de protection adapte a l"utilisation dans le cadre du procede mentionne ci-dessus. Selon l"invention, des bandes d"acier revetues d"un seul cote sont suffisamment protegees par application du materiau de protection, qui se montre superieur par ses proprietes de protection et d"adherence, sur les parties qui ne sont pas destinees a recevoir le revetement metallique par plonge a chaud. En particulier, un revetement constitue de suie ou d"une substance similaire, qui est essentiellement composee de carbone, est en premier lieu applique sur les parties de la piece (10) qui ne sont pas destinees a recevoir le revetement metallique, cette suie ou substance similaire etant produite par combustion incomplete de fuel au moyen d"un bruleur (52) dispose dans une buse (50). Ensuite, la piece a traiter est immergee entierement dans le bain (22) de plonge a chaud et refroidie par un dispositif (70). Finalement, le materiau de protection est enleve a l"aide d"une brosse a rouleau (26).
