EXPERIMENTAL STUDY, ANALYSIS, AND SYNTHESIS OF DEFECTS IN THE CASTING OF ALUMINUM INGOTS

Abstract

The goal of any enterprise is to increase the quality and productivity of production products. Casting defects are the only limitation in any casting process. The sandblasting process faces the same problem. It is very important to determine the optimal conditions for obtaining minimal casting defects. A simple method that most companies use is trial and error. But due to error-prone results and expensive and time-consuming restrictions, this method causes a lot of costs to the company. In this article, an attempt has been made to minimize casting defects by following proper practice during sand casting. From Casting Defects and their Remedies, it has been found that defects can be reduced by controlling the quality of molding sand, such as sand grain size, clay content, and moisture content. From the sand test, it was found that the clay content of the molding sand is very high and the sand particle size is coarse. This resulted in various sand-casting defects such as impact holes, compaction, sand inclusions, etc. It is very important to take preventive measures to improve quality and productivity at the industrial level. Sand casting defects can be successfully reduced by following proper practices such as proper melt treatment, optimum sand quality, correct casting temperature. All rights reserved.
