Title (EN) BRITTLE FORMED PRODUCT AND IRON-BASED POWER MATERIAL AND METHOD FOR MANUFACTURING THESE MATERIALS
(FR) PRODUIT FRIABLE ET MATERIAU EN POUDRE A BASE DE FER, ET LEUR PROCEDE DE FABRICATION
Abstract: front page image
(EN)A cotton-like coagulated article (B) comprising iron-based ground chips and a grinding fluid containing an oil and water is subjected to compression forming to manufacture a brittle formed product (C) which comprises a ground powder having fibrous particles roughly cut and does not contain excess water and oil. The brittle formed product (C) is subjected to pulverization to cut finely the particle in the ground powder, and the resultant product is admixed with a solidifying auxiliary (D) to manufacture an iron-based power material (E) containing the solidifying auxiliary (D).
(FR)Cette invention concerne un article coagulé (B) de type coton comprenant des copeaux moulus à base de fer et un liquide de rectification à base d"huile et d"eau qui est soumis à un formage par compression en vue de l"obtention d"un produit friable (C), lequel produit comprend une poudre moulue renfermant des particules fibreuses grossières sans excès d"eau oui d"huile. Le produit friable (C) ainsi formé est soumis à une opération de pulvérisation permettant de transformer les particules en poudre fine. En mélangeant le produit ainsi obtenu à un auxiliaire de solidification (D), on obtient un matériaux poudreux à base de fer renfermant l"auxiliaire de solidification.
