ALP80 Clamshell Type Copper/AL Melt Hydrogen Detector

ALP80 Main Application

ALP80 is designed mainly to test gas content in copper melt. Built with high temperature resistance, it is also suitable for AL melt. This model can rapidly, within 5 minutes, complete a qualitative test on hydrogen/gas content status of copper or aluminum melt 

before casting, therefore to decide whether the metal melt is casting ready, reducing casting waste and improving productivity. Working along with our company's degassing & refining devices, this model can help produce high-quality casts for our customers. This model conducts qualitative tests for gas content status on copper or aluminum melt, most suitable for casting factory on-site usage. By merely examining the concave-convex surface and pinhole status of the tested samples, it can be decided whether production requirements are met.

ALP80 Hydrogen/Gas Detecting Principles

ALP80 adopts decompression solidification test methods. When tested samples solidify in vacuum, hydrogen dissolved in aluminum melt will be continuously released and forms bubbles inside or on surface of the tested samples. By detecting concave-convex level of the surface or gas hole ratio of the cross section, gas volume in aluminum/copper melt can be determined. Test results decide whether samples are casting ready. Also hydrogen volume can be determined by examining the existence of cauliflower patterns on metal surface.

ALP80 Testing Methods

1.Direct observation on the tested metal surface for concave-convex status after cooling. Concave indicates low gas volume contained and convex indicates otherwise.

2.Cut tested metal after cooling and observe the cross section for the volume of gas holes. Less holes indicate low gas contained and more holes indicates otherwise.
