Metal Casting Technologies : June 2007
56 www.metals.rala.com.au PRODUCTS Measure Foundry Metal Temperatures Quickly and Safely Measuring the temperature of molten metal in a foundry can be a slow and disruptive process. The use of disposable dip thermocouples can be both expensive and hazardous. The new Meltmaster is both fast and accurate, easy to use and does not contact the liquid metal. The unique Meltmaster from Land Instruments International is a new hand-held, non-contact temperature monitor which has been designed for use only in a metal foundry. Designed specifically for the foundry industry, it can directly lead to a reduction in the use of 'dip' type thermocouple systems used for periodic checking as required by process. The 'Meltmaster' measurement mode uses advanced, noise-rejection processing which locks onto the real liquid metal temperature. Four measured temperatures can be displayed simultaneously -- peak, valley, continuous and Meltmaster. Safely and accurately measure the temperature of molten metal in a melting furnace or during pouring without disrupting the process. It can help to reduce operating costs while improving casting quality. Using the Meltmaster couldn't be easier and requires only one hand to operate. View the liquid metal stream through the viewfinder and pull the trigger, the measurement is made (in 30 ms), and can be stored or output to a data logger (either connected or via Bluetooth). The Meltmaster is ideally suited to the foundry environment, is robust and can resist heat, is battery operated (no trailing cables), with various accessories available.

They ensure flow rates are absolutely precise, thus delivering a homogeneous casting process with the lowest possible rejection rates and therefore high levels of productivity. The ceramic filters ensure castings are much stronger and also reduce tool wear during subsequent processing stages. The ceramic filters encourage laminar flow during casting and keep non-metallic inclusions to a minimum. These dry-pressed ceramic round-hole filters have already proven their reliability for large castings weighing up to 50 t.
