Prepn. of reinforcing inserts for iron castings - by immersing the inserts at least twice in a steel melt at specified temp

Steel reinforcing insertions for Fe castings are made by coating the insertions with a layer of steel by immersion in a steel melt at a temp. 15-60 deg.C, pref. 30-40 deg.C, above its m.pt. At least two immersions are carried out, each one for 3-15 sec. The process is used for making cold plates, do...

Beschreibung
Zusammenfassung:	Steel reinforcing insertions for Fe castings are made by coating the insertions with a layer of steel by immersion in a steel melt at a temp. 15-60 deg.C, pref. 30-40 deg.C, above its m.pt. At least two immersions are carried out, each one for 3-15 sec. The process is used for making cold plates, doors etc. for metallurgical furnaces. The method reduces the formation of spaces and voids and enhances the thermal conduction between the substrate and the coated metal layer. L'INVENTION CONCERNE LES TECHNIQUES DE DEPOT DE METAL SUR LES SURFACES DE PIECES METALLIQUES.LE PROCEDE FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPRENANT L'APPLICATION D'UNE COUCHE D'ACIER SUR LA SURFACE DES PIECES D'INSERTION, ET EST CARACTERISE EN CE QUE LA COUCHE D'ACIER EST APPLIQUEE EN IMMERGEANT A DEUX REPRISES LA PIECE D'INSERTION DANS UN BAIN D'ACIER LIQUIDE DONT LA TEMPERATURE EST SUPERIEURE DE 15-60C A LA TEMPERATURE DE FUSION DE CET ACIER, LADITE PIECE D'INSERTION ETANT, A CHAQUE IMMERSION, MAINTENUE DANS LE BAIN D'ACIER PENDANT UNE DUREE DE 3 A 15 S.L'INVENTION S'APPLIQUE NOTAMMENT A LA PREPARATION DE PIECES D'INSERTION RENFORCATRICES POUR DIFFERENTS MOULAGES EN FONTE, PAR EXEMPLE: OBTURATEURS ET PLAQUES DE REFROIDISSEMENT DE FOURS METALLURGIQUES, LINGOTIERES ARMEES, ETC.
