Biofuels production become a target for many researchers nowadays. Biodiesel is one the most important biofuels that are produced from biomass using economics and modern techniques. The ductile cast iron solid waste dust of wastes by industry which has bad effect on environment. This paper investigates possibility reusing as biodiesel heterogeneous catalyst used in its sunflower cooking oil. Fo...

Subject of the investigation is a bimetallic mill roller with external, working layer from high chromium material and inner, supporting ductile cast iron. The processes, accompanying formation transition in castings, produced by centrifugal casting have been investigated. Attention has paid to structural changes zone, caused diffusion processes occurring during crystallization.

Amatikulu Sugar Mill has installed Austempered Ductile Iron (ADI) block links and side plates on two diffuser chain strands. These links were cast in South Africa at a substantially lower cost than forged chain links. Some development emerged concerning the pattern, casting procedures and quality assurance required to ensure that high quality links were produced. Extensive tests were performed ...

The classical casting material cast iron is experiencing a renaissance. High strength CGI or alloyed cast iron components are substituting previously used non-ferrous castings in automotive power train applications. The mechanical engineering industry has recognized the value in substituting forged or welded structures with stiff and light-weight cast iron castings. New products such as wind tu...
