“…The present approach is based on the lean production concept, i.e., “do more with fewer resources” and “do it better.” It serves as an essential tool to identify the original, most authentic cause or causes of an extremely complex problem. Based on this analysis, the organization can diminish the problem or avoid similar errors in the future [41].…”

Internal Cracks and Non-Metallic Inclusions as Root Causes of Casting Failure in Sugar Mill Roller Shafts

The sugar mill roller shaft is one of the critical parts of the sugar industry. It requires careful manufacturing and testing in order to meet the stringent specification when it is used for applications under continuous fatigue and wear environments. For heavy industry, the manufacturing of such heavy parts (>600 mm diameter) is a challenge, owing to ease of occurrence of surface/subsurface cracks and inclusions that lead to the rejection of the final product. Therefore, the identification and continuous reduction of defects are inevitable tasks. If the defect activity is controlled, this offers the possibility to extend the component (sugar mill roller) life cycle and resistance to failure. The current study aims to explore the benefits of using ultrasonic testing (UT) to avoid the rejection of the shaft in heavy industry. This study performed a rigorous evaluation of defects through destructive and nondestructive quality checks in order to detect the causes and effects of rejection. The results gathered in this study depict macro-surface cracks and sub-surface microcracks. The results also found alumina and oxide type non-metallic inclusions, which led to surface/subsurface cracks and ultimately the rejection of the mill roller shaft. A root cause analysis (RCA) approach highlighted the refractory lining, the hot-top of the furnace and the ladle as significant causes of inclusions. The low-quality flux and refractory lining material of the furnace and the hot-top, which were possible causes of rejection, were replaced by standard materials with better quality, applied by their standardized procedure, to prevent this problem in future production. The feedback statistics, evaluated over more than one year, indicated that the rejection rate was reduced for defective production by up to 7.6%.

This chapter illustrates how the author upgraded the library website at an urban junior college, evaluating the efficacy of the single search box and how to support information literacy. As a framework, the author used the United States Department of Energy's Root Cause Analysis Guidance Document, which illustrates root cause analysis, a process to uncover, analyze, and resolve issues or problems of user behavior relating to technology. A usability test of the library's website using student subjects supplied data for data collection. Events and causal factor analysis identified the causes of problems observed in the usability test and corrective actions required to mitigate them. Results determined what design strategies promote information literacy on a library website and if the single search box is the best fit for an urban junior college.
