Title (EN) PROCESS AND APPARATUS FOR THE PRODUCTION OF METALLIC COMPOSITIONS
(FR) PROCEDE ET APPAREIL DE PRODUCTION DE COMPOSITIONS METALLIQUES
Abstract: front page image
(EN)Process and apparatus for the production of a metallic composition, such as ferro-magnesium, wherein one constituent has a melting point which is above the boiling point of the second constituent. A liquid melt of the first constituent has an effective depth sufficient to produce a static pressure head in excess of the vapor pressure of the second constituent at the temperature of the melt. The second constituent in the molten form is mixed with the first constituent to form a liquid mixture wherein at least a portion of the second constituent is in the solution with the first constituent. The mixture if a solid metallic composition is to be found is solidified rapidly to form the solid metallic composition in which a substantial part of the second constituent appears as a dispersion of fine particles of the second constituent in a matrix of the first constituent. The apparatus includes a columnar furnace (10) communicating with a reaction chamber (16) to provide the requisite pressure within the reaction chamber (16), an adder mechanism (18) to supply the low-boiling point constituent to the pressurized reaction chamber and means (20, 22, etc.) to cool and solidify the liquid mixture rapidly so as to form the desired dispersion of fine particles of the low-boiling point constituent in a matrix of the other constituents.
(FR)Procede et appareil de production d"une composition metallique, telle que du ferro-magnesium ou un constituant possede un point de fusion superieur au point d"ebullition du second constituant. Une coulee liquide du premier constituant presente une profondeur effective suffisante pour produire une colonne ou hauteur manometrique statique depassant la pression de vapeur du second constituant a la temperature de la coulee. Le second constituant en fusion est melange avec le premier constituant pour former un melange liquide ou au moins une partie du second constituant est en solution avec le premier constituant. Le melange, si l"on veut obtenir une composition metallique solide, est solidifie rapidement pour former la composition metallique solide dans laquelle une bonne partie du second constituant apparait sous forme d"une dispersion de fines particules dans une matrice du premier constituant. L"appareil comprend un four a colonne (10) communiquant avec une chambre de reaction (16) pour obtenir la pression necessaire dans la chambre de reaction (16), un mecanisme d"addition (18) pour approvisionner en constituants ayant un point d"ebullition bas la chambre de reaction pressurisee et des moyens (20, 22) etc. pour refroidir et solidifier le melange liquide rapidement de maniere a former la dispersion desiree de fines particules de constituants a bas point d"ebullition dans une matrice formee par les autres constituants.
