控制铝熔体的含氢量对获得优质产品具有重大意义。为了控制液态金属中的含气量还要在铸造之前使用适当的除气剂和除气方法。因此需要有一种直接测定铝熔体中含气量的方法。本文介绍的“铝熔体测试仪”,是一种供铸造生产用的测试仪,它的工作方法以达尔德尔第一个气泡法的原理为依据。这种测试仪是在著名的Hycon-测氢仪的基础上发展起来的。铝熔体测试仪和测氢仪都是一种快速测试仪,用这两种测试仪在5
Controlling the hydrogen content of the aluminum melt is of great importance for obtaining quality products. In order to control the gas content of the liquid metal, it is also necessary to use a suitable outgassing and outgassing method prior to casting. There is therefore a need for a method of directly measuring the amount of gas contained in an aluminum melt. The “Aluminum Melt Tester” described in this article is a tester for casting production. Its working method is based on the principle of the first bubble method by Daldell. This tester is based on the famous Hycon-hydrogen instrument developed on the basis of. Aluminum melt tester and hydrogen tester are a fast tester, with these two tester in 5
