Abstract
L'invention concerne la fonderie. Elle a pour objet un procédé pour produire des noyaux et moules de fonderie par un procédé au silicate et au dioxyde de carbone, suivant lequel le silicate servant de liant comprend un silicate de potassium d'un rapport molaire SiO2 :K2 O de 1,6:1 à 2,2:1. Ce silicate peut être additionné d'une quantité pouvant s'élever jusqu'à 75 % du poids de l'ensemble des silicates, d'un silicate de sodium d'un rapport SiO2 :Na2 O de 1,65:1 à 2,8:1. Ce procédé est préféré pour la fabrication de moules et noyaux qui durcissent rapidement sous l'effet du CO2 et se désagrègent aisément après la coulée des métaux.The invention relates to the foundry. It relates to a process for producing foundry cores and molds by a silicate and carbon dioxide process, according to which the silicate serving as a binder comprises a potassium silicate with a SiO2: K2 O molar ratio of 1.6 : 1 to 2.2: 1. This silicate can be added with an amount which can amount to up to 75% of the weight of all the silicates, a sodium silicate with a SiO2: Na2 O ratio of 1.65: 1 to 2, 8: 1. This process is preferred for the manufacture of molds and cores which harden rapidly under the effect of CO2 and easily disintegrate after the casting of metals.
