Abstract
This paper reports the results of research on the effects of drawing speed on the structures and properties of leaded brass. The material used for the study was obtained via a laboratory horizontal continuous casting process. Horizontal continuous casting in a graphite mold represents a fast method for producing crystalline materials. In this process, molten metal crystallizes in a graphite mould on which a water-cooled copper jacket is applied. This step is often called primary cooling, as opposed to secondary cooling, which involves pouring water onto the surface of the rod using special nozzles. The crystallized rod is pulled out using a withdrawal unit (drawing speed). In brass, zinc causes the formation of alpha (alpha) and beta prim 03 ') phases. The effects of drawing speed on the structure and properties of brass rods obtained in the laboratory horizontal continuous casting process were analysed. The chemical composition, macrostructure, microstructure, mechanical properties, surface roughness and conductivity properties were investigated. An increase in the drawing speed in the analysed range causes a refinement of the microstructure and growth of the grain boundaries. As the grain size decreases, the Vickers hardness and proof stress (Rp0.2) of the cast brass increase, the total extension at fracture (At), and the surface quality decrease.
