COMPOSITIONS AND METHODS OF USE THEREOF IN SANDCASTING

Compositions useful for foundry processes such as green sandcasting are discussed. The compositions may include ball clay, bentonite, and a carbonaceous material. The ball clay may include leonardite and/or causticized lignite, e.g., as a portion of the natural ball clay deposit. The composition may...

More Information
Summary:Compositions useful for foundry processes such as green sandcasting are discussed. The compositions may include ball clay, bentonite, and a carbonaceous material. The ball clay may include leonardite and/or causticized lignite, e.g., as a portion of the natural ball clay deposit. The composition may further include sand, such that the resulting mixture may be formed into a green sand mold for use in casting molded articles. Incorporation of ball clay materials in the compositions may help to improve the quality of the casted article.
