Casting Method With In-Process Composition Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In casting facilities, the increased workload for personnel in inspecting diverse casting products before shipping poses a challenge due to the need for manual verification of product appearance and properties, which can lead to inefficiencies.
Innovation Solution
A casting method that includes sampling molten metal to create a test piece, analyzing its composition and physical properties, and displaying these results during the inspection of the casting product, allowing personnel to accurately identify and verify the product's characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection of casting products is performed by working personnel, then appearance inspection can be conducted, but the workload increases and inspection efficiency decreases
Solution Approach 1:
The analysis of composition and physical properties is performed in advance on test pieces generated from the molten metal, so that when inspection occurs, the data is already available on display. This preliminary analysis action reduces the workload during actual inspection while maintaining accuracy.
Solution Approach 2:
Test pieces are created as copies or representations of the actual casting products for analysis. By analyzing these test pieces instead of the products themselves, the system obtains composition and property data without interfering with the final product inspection process.
2Reliability
If working personnel must specify and identify each casting product sequentially, then inspection can be performed, but the complexity of work operation increases
Solution Approach 1:
The system provides feedback by displaying the composition and physical property data of test pieces on a display device during inspection. This feedback mechanism helps working personnel quickly identify and verify product characteristics without manual specification, reducing operational complexity while maintaining reliability.
3Measurement precision
If analysis of test pieces is performed on molten metal sampled from ladle, then composition accuracy improves, but the time required for sampling and analysis increases
Solution Approach 1:
Sampling and analysis of test pieces are performed as preliminary actions before the final inspection stage. By completing analysis early and displaying results, the system minimizes the time impact on the main production flow while ensuring accurate composition data is available when needed.

AI summary
A casting method includes pouring a molten metal in a ladle into a mold, analyzing at least one of a composition and a physical property of a test piece generated based on the molten metal sampled from inside the ladle, and performing appearance inspection of a casting product taken out from the mold, wherein in the performing appearance inspection, the at least one of the composition and the physical property of the test piece obtained in the analyzing is displayed on a display.
