The work investigated the possibility of using the technical lingo-sulfonate as a binder for the manufacture of small cores by blow-off methods in the production of shaped cast-iron casting, similar to the dominant at the present time Cold-Box-Amin process. It is shown that the advantage of lignin materials is their safety, manifested both in the workplace - directly in the foundry, and in ensuring environmental cleanliness in the area of the location of such production. It is indicated that, when switching to the proposed lignin materials, the price of binders can be reduced by two orders of magnitude. Experimental compositions of mixtures are proposed, and their tests are carried out. The quantitative characteristics of the composition of the sand-oligo-sulfonate mixture are established. As a result, a pilot batch of rods was produced, and high-quality shaped cast iron castings were made. Special attention is paid to the demand to develop the specialized equipment, focused on lignin binders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
