Currently, approximately 70-80 % of casting production of ferrous alloys is done with sands containing bentonite (green sands). Information on an amount of active bentonite in moulding sands, after shakeout of casting, is necessary in the rebounding process of bentonite sands – under real casting house conditions. It decides how much of fresh bentonite should be added to moulding sands, thereby...

Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength and are increasingly seen as an alternative to conventional materials, particularly in the automotive industry. In this study, a historical background on the development and application of metal matrix composites for automotive brake rotors is presented. The dis...

The paper analyses how technology, market and policy issues condition the adoption of aluminum in the manufacturing of auto engine blocks in Brazil. Due to important weight savings, there is a clear tendency in the auto industry to change engine material from iron and steel to aluminum. This tendency has started in the triad market area, mostly because of scale issues, but the increasing global...

Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength property and are increasingly seen as alternative to the conventional materials particularly in the automotive industry. In this study, a historical background on the development and application of metal matrix composite for automotive brake rotor is presented. ...

The aim of conducting this research was to evaluate the viscosity change in the continuous casting of steel mold powders by altering their chemical compositions, using hot stage microscope analysis. 4 low-fluorine samples containing such compositions as MnO, Fe2O3, Li2O, TiO2 and ZnO, as well as another fluorine-free sample containing a combination of Fe2O3 and TiO2, were prepared in this resea...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...

A two-year program was conducted to develop and commercially manufacturing technologies to: • Enable significant reductions in the costs of castings, • Increase the complexity and dimensional accuracy of castings, and • Reduce the development times for delivery of high quality castings. implement selected casting The industry-led R&D project was cost shared with NASA's Aerospace Industry Techno...

quality inspection is an indispensable part of modern industrial manufacturing. steel as a major industry requires constant surveillance and supervision through its various stages of production. continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. once the slab is released from the casting unit, th...
