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...

 Evaluate the impact on pipe performance and life expectancy of the transition (1991) from wall thickness class to pressure class designations in the manufacture and design standards for ductile iron pipes.  Study and compare historical failure rates of ductile iron pipes in a geographically diverse group of water utilities from North America and Australia.  Evaluate reliability and capabili...

The fatigue strength offerritic ductile iron, Grade EN-GJS-400-18U-LT. was determined for large section castings measuring 4 by 24 by 24 inches. Fatigue testing was conducted in bending fatigue in order to determine the influence of surface conditions on fatigue strength. Test specimens with various surface conditions were evaluated, including notched and un-notched specimens, as well as those ...

We have investigated the anomalous Ettingshausen effect (AEE) in iron–carbon alloys, i.e., cast irons and steel, using lock-in thermography. All alloys exhibit clear AEE-induced temperature modulation, their coefficient is an order of magnitude greater than that pure iron at room temperature. The dimensionless figure merit for AEE ductile 55 times owing to significant increase coefficient. Our ...
