Article Synopsis
- The study explores the use of barley malt as a natural binder for molding sand, revealing that around 75% of the malt binder is organic matter, primarily starch.
- Tests demonstrated that barley malt effectively connects quartz sand grains, enhancing the mechanical properties of the mold while improving surface quality of castings.
- However, higher concentrations of barley malt led to increased gas evolution during pouring and a 25% increase in the thickness of the burnt layer, important considerations for recycling the molding sand.
Results of a study on influence of Cr, Mo and Al on the microstructure, abrasive wear and corrosion resistance of Ni-Mn-Cu cast iron in the as-cast and heat-treated conditions are presented. Because of the chilling effect of first two elements (tendency to create hard spots), graphitising Al was added to the alloys, with the highest concentration of Cr and Mo. All castings in the as-cast condition showed an austenitic matrix, guaranteeing good machinability.
