An Application of Pareto Analysis and Cause Effect Diagram for Minimization of Defects in Manual Casting Process
Casting has various processes like Pre casting Processes, pattern making, core making, molding and mold assembly making, Casting Processes, furnace charging, melting, holding and pouring, and Post casting Processes, shakeout, inspection and dispatch etc. In India there are many foundry have followed conventional and manual operations. Today’s competitive environment has, lower manufacturing cos...
متن کاملAn Investigation of Casting Defects Revealed in Forming Process of USD7 Steel
USD7 is one of the steel products of Isfahan Steel Company. It is cast in continuous casting moulds and rolled up to a rod of 5 mm diameter. Finally, it is wire drawn up to 3 mm and used as welding electrodes. This steel contains 0.05 to 0.09 wt. % carbon. The acceptable limit of the aluminium in this class of steel is less than 0.003 wt%. Therefore, it is categorized as rimmed steel...
متن کاملStudy of Process Parameters of Gravity Die Casting Defects
In today’s world a casting production without any defect is almost impossible. After the application of various optimization techniques and process we still are not able to get the defect free castings. So it is critically important to analyze the root cause of casting defect with in the process itself, so that any changes which can hamper the defect intensity can be invoked at the time of manu...
متن کاملModeling of Hot Tearing and Other Defects in Casting Processes
AS COMPUTATIONAL MODELS MATURE, their practical benefit to improving casting processes is growing. Accurate calculation of fluid velocities, temperature, microstructure, and stress evolution is just the first step. Achieving tangible improvements to casting processes requires the accurate prediction of actual casting defects and product properties. Defects that form during solidification are im...
متن کاملControl Structure for the Reduction of Defects in Continuous Casting
The causes for surface defects in the con tinuouscasting process must be understood so that surface defects can be eradicated. The defects which were considered are presented and an approach to eliminate many of the in uencing variables using statistical hypothesis testing is presented. These methods show that only the thermocouple temperature readings within the mould are necessary to accurate...
