Green sand molding for metal casting makes up around 70% of the total castings produced worldwide. Silica sand mining and its transportation to foundries harm the ecosystem, rendering this metal casting process environmentally unsustainable. This research paper introduces a novel method of partially replacing the silica sand with biomass ash - a waste product of combustion in various processes such as domestic and commercial cooking. Suitable experiments were conducted to measure the effects of mixing progressively higher proportions of biomass ash (from 9% to 30%) in conventional green sand mold. The molds then underwent tests for the evaluation of technological properties such as green compression strength, green shear strength, permeability and compaction. After suitable pattern making, the molds were tested for casting using LM 24 Aluminium Alloy. The obtained Aluminium Alloy castsings underwent micro hardness tests and micro structure study. The results obtained for biomass ash molding sand were compared with the corresponding tests results for conventional sand mold casting and the results were satisfactory.

In recent days many business organizations make huge investment in establishing their shop floors, installing most mechanized machines. These mechanized machines ought to operate in tandem with other machines, whose productivity level are usually different, which leads to individual machines working in maximum efficiency and the overall shop floor working in sub-optimal level. A spool shop assembles flanges, valves and nozzles to lengthier pipe, which are used in the construction of power plant, petroleum refinery, and cement plant. Longer cycle time at different work stations, lengthier job queue waiting for processing, high level of work-in-progress are inherent issues in a spool shop. Individual machines operating at maximum efficiency without analyzing the flow metrics in a spool shop leads to bottleneck. Current study, aims at spotting and decongesting the bottle neck at various machines, improve the output of the spool shop and optimize individual machine utilization. Four simulation models are developed using ARENA and each one of them are evaluated on the following metrics: Output from spool shop per time period, utilization of individual machines per time period, value added time per unit of pipe, average queue length at each machine, average waiting time of a pipe and work-in-progress. First model depicts the data captured in the existing spool shop. In second model, high priority is assigned to the jobs that ought to be further processed in shot blasting machine and heat treatment furnace, thus minimizing the wait time. In third model, a modification is suggested to the existing annealing process, where the job is allowed to cool outside the furnace, thus making the furnace available for the next job. Forth model uses the priority rule in the suggested modified model. In all these models, inter-arrival time of job from storage yard to spool shop is maintained constant. Evaluating each model against performance statistics and queue statistics helps rank models based on each metrics. Models with high priority for further processing make use of single piece flow, a proven lean principle technique that has enhanced the overall efficiency. This eventually motivates practicing shop floor manager to incorporate flow metrics in designing the layout and machine capacity for optimal overall utilization. © 2006-2016 Asian Research Publishing Network (ARPN).

M. M. Mathew, M. Thennarasu, Aravind, G., and Selvaraj, J., “Performance comparison for aluminium, copper and steel shots in waste heat recovery and scrap preheating from solidifying molten metal”, ARPN Journal of Engineering and Applied Sciences, vol. 11, pp. 6094-6099, 2016.[Abstract]


During solidification of molten metal in sand casting, the sensible, latent and superheat are lost to the sand. This research article focuses on waste heat recovery from solidifying molten metal and scrap preheating using the recovered heat. This is done by incorporating an intermediate heat transfer medium such as aluminium, copper and steel shots in green sand mould. These intermediate heat transfer media absorb the heat from the solidifying metal in the mold cavity; the heated shots are separated from the mold and allowed to transfer their heat energy to the metal scrap by conduction, convection and radiation. The experiments prove that 8.4 % of heat recovery is achievable by introducing copper shots with the green sand mold, compared to aluminium shots, which generates 3.7 % and steel shots achieving 3 %. This method has the potential to be instrumental in reducing the enormous amount of energy spent to melt the metal in foundries. The experiments reveal that about 84 kWh of energy can be saved by using copper shots for melting one ton of metal. Cumulative effect of this novel energy conservation method on energy costs and global warming mitigation is found to be very convincing for industrial implementation, particularly for countries such as India. © 2006-2016 Asian Research Publishing Network (ARPN).

Energy conservation is a major topic of concern since our energy sources are exhausting exponentially. This paper focuses on waste heat recovery using which scrap preheating is done in metal castings using sand molds. During solidification of molten metal, most of the heat is lost to the sand. The proposal is to prepare the sand mould with aluminium shots surrounding the mold cavity. These shots absorb some of the heat from the solidifying metal in the mold cavity. The heated shots are separated from the mold and they are allowed to transfer their heat energy to the metal scrap by conduction. The experiments indicate that at least 6.4% of heat recovery is achievable. This will be instrumental in reducing the enormous amount of energy spent to melt the metal considering the fact that casting is the most widely used manufacturing process globally.

M. Thennarasu, ,, ,, and M. kumar, A., “Investigation of Mechanical and Wear Behavior of LM 24 Aluminum Alloy for Different Types of Casting”, Research India Publications, International Journal of Applied Engineering Research, vol. 10, 2015.[Abstract]


This paper compares the mechanical and wear behaviour of LM 24 (Al-Si8Cu3Fe) aluminium alloy that were fabricated using different casting process. The specimens were fabricated using the sand, plaster mold and die casting. For each casting, hardness test and charpy test were performed individually to study the effect of different casting characteristics on the hardness and impact strength. Pin on disc tribometer was used to study the dry sliding wear behaviour for different castings. The results showcased that the hardness, impact strength and wear resistance decreased in the order of die, plaster mold and sand castings. Die cast specimens showed highest hardness (84.87 BHN), high impact strength (2.54J/m2) and low wear rate (0.102 mm3/m) compared to sand and plaster mold cast specimens.
