Hydrogen is one of the key factors that affects molten aluminum quality<\/strong>. Excessive hydrogen can contribute to structural defects and gas-related porosity in aluminum castings.<\/p>\n Therefore, monitoring hydrogen content before and during casting is important for maintaining consistent melt quality.<\/p>\n NOTORP BU2<\/strong> is a hydrogen analyzer designed for molten aluminum alloys<\/strong>. It provides fast and continuous hydrogen measurement while the sensor remains immersed in molten aluminum during degassing or refining.<\/p>\n Molten aluminum can absorb hydrogen during melting and holding. When the metal solidifies, excess hydrogen can form gas pores inside the casting.<\/p>\n As a result, uncontrolled hydrogen levels can increase the risk of casting defects.<\/p>\n Regular hydrogen measurement helps foundries:<\/p>\n NOTORP uses a proton-conducting ceramic sensor<\/strong> to measure hydrogen concentration directly in molten aluminum.<\/p>\n The sensor uses a reference gas containing 1% hydrogen and 99% argon<\/strong>. When the sensor is immersed in molten aluminum, it detects the hydrogen-related electromotive force generated between the molten metal and the reference gas.<\/p>\n The system then calculates the hydrogen concentration using Sieverts’ law<\/strong>.<\/p>\n This measurement principle allows NOTORP to monitor hydrogen directly in the molten metal.<\/p>\n One of the main advantages of NOTORP is continuous measurement<\/strong>.<\/p>\n The sensor can remain immersed in molten aluminum while the process is running. Therefore, operators can monitor changes in hydrogen concentration without repeatedly taking samples.<\/p>\n NOTORP can also measure hydrogen during:<\/p>\n This makes the system useful for monitoring melt quality throughout the production process.<\/p>\n Hydrogen measurement becomes especially useful during rotary degassing<\/strong>.<\/p>\n As inert gas bubbles through the molten aluminum, dissolved hydrogen moves into the bubbles and leaves the melt.<\/p>\n With continuous measurement, NOTORP can track the change in hydrogen concentration during the treatment.<\/p>\n For example, a measurement using AC4CH (A356.2)<\/strong> aluminum alloy shows the hydrogen concentration changing during rotary nitrogen bubbling at 300 rpm and 3 L\/min<\/strong>.<\/p>\n This allows operators to see the actual effect of degassing instead of relying only on a fixed treatment time.<\/p>\n NOTORP BU2 provides several features for molten aluminum quality control:<\/p>\n NOTORP can be used with a wide range of aluminum alloys.<\/p>\n The application list includes alloys used for direct chill casting, die casting, and other aluminum casting processes<\/strong>. The listed alloys include common grades such as A356, A357, A380, A390, ADC10, ADC12, and several wrought aluminum alloys<\/strong>.<\/p>\n This makes NOTORP suitable for different aluminum production environments where hydrogen control is important.<\/p>\n Effective degassing should not rely only on treatment time.<\/p>\n With continuous hydrogen measurement, operators can see how the hydrogen concentration changes during the process.<\/p>\n The process becomes:<\/p>\n Degassing \u2192 Hydrogen Measurement \u2192 Process Evaluation \u2192 Quality Control<\/strong><\/p>\n This approach helps production teams make decisions based on actual hydrogen concentration<\/strong>.<\/p>\n As a result, foundries can better optimize their degassing parameters and maintain more consistent molten aluminum quality.<\/p>\n NOTORP BU2 provides a direct and continuous way to monitor hydrogen in molten aluminum.<\/p>\n Its fast response, continuous measurement, and ability to operate during degassing make it a valuable tool for aluminum melt quality control<\/strong>.<\/p>\n At PT Wilisindomas Indahmakmur<\/strong>, we provide solutions for aluminum melting, melt treatment, and quality control.<\/p>\n Contact us to learn more about NOTORP Hydrogen Analyzer<\/strong> and how continuous hydrogen measurement can improve your aluminum melt treatment process.<\/p>\n","protected":false},"excerpt":{"rendered":" Hydrogen Analyzer for Molten Aluminum Hydrogen is one of the key factors that affects molten aluminum quality.
