Title (EN) FURNACE WITH MOVING GIRDERS COMPRISING BUILT-IN PARTS
(FR) FOUR A LONGERONS MOBILES ET COMPRENANT DES PIECES RAPPORTEES
Abstract: front page image
(EN)The furnace used for heating steel comprises combustion chambers arranged above and underneath the product to be heated and hollow steel girders (d) arranged longitudinally with respect to the furnace, attached to supports and cooled by a fluid stream. A very uniform heating of the product to be heated is obtained owing to the fact that built-in parts are secured to the girders: the portion of girders (d) which is close to the inlet of products to be heated comprises built-in parts made of one or two elements whereas the portion close to the outlet is provided with parts of three support elements (a) which are arranged loose on the girders (d) and which are subdivided into compartments by transversal partition walls (h), insulating elements (b) of ceramic material arranged into the compartments of the support elements (a), and metal sliding elements (c), very resistant to heat, bearing on the insulating elements (b) and provided with appendices (i) of which the vertical surfaces (j) are next to corresponding surfaces (k) of the support elements (a).
(FR)Le four utilise pour le rechauffement d"acier comprend des chambres de combustion disposees au-dessus et au-dessous du produit a rechauffer et des longerons creux en acier (d) disposes longitudinalement par rapport au four, fixes sur des supports et refroidis par un courant de fluide. Un echauffement tres uniforme du produit a echauffer est obtenu par le fait que des pieces rapportees sont fixees sur les longerons: la partie des longerons (d) qui est pres de l"entree des produits a rechauffer, comprend des pieces rapportees a un ou deux elements tandis que la partie proche de la sortie est pourvue de pieces a trois elements de support (a) qui sont poses librement sur les longerons (d) et qui sont subdivises en compartiments par des cloisons transversales (h), des elements isolants (b) en matiere ceramique loges dans les compartiments des elements de support (a), et des elements coulissants metalliques (c), tres resistants a la chaleur, appuyes sur les elements isolants (b) et pourvus d"appendices (i) dont les surfaces verticales (j) sont voisines des surfaces correspondantes (k) des elements de support (a).
