At present,the foundry industry that applied green sand casting with pulverized coal clay bonded sand has suffered severe pollution,high consumption,and poor quality of casting surface,which is not in accordance with the current industrial policy of energy-saving and consumption-reducing.Thus,to explore a resource-conserving green casting process has great practical significance.
2014-2-20ensp0183enspDepartment of Mechanical Engineering, Bhilai Institute of Technology, Durg, India ABSTRACT Among the industrial activities sand casting process still remains as one of the most complex and indefinite activities.
Malaysia has an estimated resource of 640 Mt of silica sand, of which 148 Mt are natural silica and 492 Mt tailing sand. The objective of this study is to determine the physical and chemical properties of the Perak River sand as a molding mineral for making greensand casting molds. Six samples were taken randomly at the marked identified locations.
Abstract. In this work, the effects of reclaimed sand additions on the microstructure characteristics, mechanical properties and fracture behavior of furan no-bake resin sand have been investigated systematically within the temperature range from 25 to 600 186C.
The research shows that addition of Fe filings to green moulding sand have no adverse effects on the casting abilities of the sand. This suggests that Fe filings could be added to green moulding sand to change its heat storage capacity without any adverse effects on the vital properties of green moulding sand.
The angularity of a sand increases with use because the sand is broken down by thermal and mechanical shock. The porosity of the mold controls its permeability, which is the ability of the mold to allow gases generated during pouring to escape through the mold.
2019-1-22ensp0183enspGreen sand castings can be heat-treated to reduce residual stresses and improve mechanical properties. Also, by placing chills in the mold, hardness and wear resistance of the casting can be increased at desired locations. 9. Like other casting processes, green sand casting has its limits.
