Sugar industry fly ash: an additive for molding sand to make aluminium castings

Abstract

X ray diffraction, thermogravimetric analysis, scanning electron microscopy and energy disper sive spectroscopy studies were performed with molding sand and sugar industry fly ash to evaluate and com pare their physical properties. We noted that several physical properties of sugar industry fly ash and molding sand were similar. We then tested the permeability, green compression strength and dry compression strength of various compositions of sugar industry fly ash and bentonite to explore their potential as an alternative to molding sand, thereby reducing the dependency on the latter, as well as to suggest an effective way for disposal of fly ash from sugar industry. We also found that quality aluminium castings could be produced using fly ash, which effectively replaced 24% of molding sand in the foundry, thereby reducing the cost of production and increasing the surface finish of castings.

Challenges and Future Prospective of Alternative Materials to Silica Sand for Green Sand Mould Casting: A Review

“…The effect of bentonite clay and fly ash on sand mould property is shown in Fig. 1 [56]. It is observed that the mould permeability and strength decrease as the concentration (wt%) of sugar industry fly ash increases in moulding sand.…”

“…Sugar industries produce fly ash by burning the sugarcane bagasse [56]. The effect of bentonite clay and fly ash on sand mould property is shown in Fig.…”

Optimization of Four Stroke c.i. Engine Performance by using Statistical Techniques (Mathematical Method)

“…Single zone model assumes the charge as homogeneous and single wiebe heat release model is widely used to model SI combustion. Here we use two wiebe model as we are simulating a Direct Injection Diesel Engine [37][38][39][40][41]. Heat transfer by convection from gas to the cylinder walls or from the cylinder walls to the gas is considered over the entire cycle.…”

Design and Development of Semi-Automated Clip Bracket in Automotive

“…The luminaire is a fixture used in the manufacturing industry. It is used to attach accessories (placement in a specific location or orientation) and to support the work [32][33][34][35][36]. Improving the efficiency of production by simplifying ducing the need for skilled labour and increasing the compatibility of workers in production.…”
