The Evaluation Model Efficiency of Ladle Graphitizing Inoculation of Cast Iron

Abstract

The model for evaluation of quality of ladle graphitizing inoculation of cast iron, according to the most common technological schemes, using the triple integral, is proposed and implemented. The necessary boundary conditions and parameters of the integral model are presented, described and justified. A concrete example confirms the practical conclusion that graphitizing inoculation of cast iron, melt into a stream in the process of filling a mold, is preferable.

Research on the evaluation model of rural colony tourism resources based on AHP

“…To sum up, it can be considered that rural tourism resources are all the tangible and intangible resources that can be used for tourism and can be used for tourism within a certain territorial scope on the basis of ecological protection and other development principles [3] . Evaluation of tourism resources refers to determining the status of a certain tourism resource among all tourism resources or similar tourism resources according to certain criteria, that is, comparing tourism resources both vertically and horizontally, in order to determine the importance and development value of a certain tourism resource [4] . Specifically, tourism resource evaluation is to make scientific value judgment on the quantity and scale of tourism resources, quality level, regional environment, development conditions, utilization prospect and other ISSN 2616-5775 Vol.…”
