Benefits of technology

This patented technology uses an image capturing technique for measuring how well liquids behave when poured into containers or other objects quickly without being affected too much during their production time. It allows us to record all that happens while it's still flowable but also has fast-acting controls over its cooling period. By analyzing this data we are able to determine whether there will be any issues affecting the quality of the final product before they reach consumers through mass distribution channels like retail stores.

Problems solved by technology

This patents describes various ways to measure how well liquids behave before they cool down from their molten state. One way involves mechanically checking if these materials have enough fluidness at room temperatures without actually melting them up again after being casted onto another material called an investment layer made of ceramic fiber cloth (CFF). Another approach uses specialized equipment like vibrating tools instead of relying solely upon gravity alone. These techniques aim to provide precise data about the properties of the fluorescent powder-filled resin composition.

Abstract

Relating to testing devices for liquid metal fluidity and testing methods based on the devices, the invention provides a visual testing device for liquid metal fluidity and a testing method based on the device. The device and method provides a solution to the problem of low testing accuracy caused by invisible pouring speed and pouring temperature in present methods. The device comprises: a CCD camera arranged below a high temperature resistant quartz glass plate, an insulating pouring cup positioned over a clay sand cope flask, with the pouring gate of at the bottom of the insulating pouringcup in correspondence with the upper part of the clay sand cope flask. The testing method consists of: pouring a liquid metal into a fluidity testing cavity, and measuring the temperature; shooting an image with the CCD camera below the high temperature resistant quartz glass, and conducting computer analysis so as to obtain a test result. The device and method provided in the invention is suitable for testing liquid metal fluidity.
