Title (EN) SHEARING OF METAL PLATE
(FR) CISAILLAGE DE TOLE METALLIQUE
Abstract:
(EN) A method and apparatus for shearing plate stock involves conveying on a conveyor a single layer of scrap sheet material between a fixed serrated lower blade and a downwardly movable complimentarily shaped upper blade. The upper blade is moved downwardly to shear the sheet material such that due to the complimentary shaped upper and lower serrated blades, the sheared material is in the form of a series of corner linked parallelograms. The pellets produced are typically from scrap steel plate stock and particularly suitable for use in cooling molten steel when introduced therein.
(FR) Méthode et appareil pour le cissaillage de tôle. On transporte sur une chaîne une couche unique de tôle placée entre une lame inférieure fixe et dentelée et une lame supérieure déplaçable vers le bas et de forme complémentaire à la première. La lame supérieure est abaissée pour cisailler la tôle de manière qu'en raison des formes complémentaires des deux lames dentelées, le matériau cisaillé prenne la forme d'une série de parallèlogrammes reliés par leurs angles. Les boulettes ainsi fabriquées sont de façon caractéristique à base de plaque d'acier de rebut et sont particulièrement bien adaptées pour être introduites dans de l'acier en fusion afin de le refroidir.
