摘要: Systems and methods for improved molding sand performance through use of recovered additives from the existing waste stream in a foundry. Sand, clay, and carbon-containing organic components are wet recovered from a green sand mold foundry dust recovery system. The sand and non-sand fractions may be further treated to reduce water content or adjust the levels of various components to generate a pre-mix additive for the generation of new green sand molds, that may display improved properties at ambient and high temperatures when compared to commonly employed traditional pre-mix. In some examples, pre-mixes having reduced sulfur content are obtained. In several embodiments, the non-sand fraction obtained from bag house dust or dust from mechanical reclamation includes increased levels of bentonite clay and carbon.

摘要: Described herein, in the preferred embodiment, is a leonardite-based polyurethane resin binder that may be used, among other applications, as a binder in combination with foundry aggregate, e.g., sand, for molding or casting metal parts. The binders described herein comprise a humic substance, preferably leonardite, combined with a polymerizable polyol, an isocyanate, and a polymerization catalyst to make a polyurethane resin binder in situ in a foundry aggregate, such as sand. The lignite is mixed with the polymerizable polyol and dispersing agents as additives to improve the suspension quality and binder performance of the lignite-containing part of the binder components.
