Intelligent Control for the Smart Foundry
Nearing the quarter of the 21st century, it seems technology is advancing faster and faster every year. Why shouldn’t your facility advance too? This post will provide some options for you to consider as you’re researching, designing, and improving your process.
Low Air Flow Freezes Pumps!
The primary reason for molten metal pump freezing is "slow starts." A slow-start is defined as slowly increasing the motor RPM. When a transfer pump is slow-started, the hot metal flows gradually into a cooler riser. As the metal temperature decreases, it solidifies or freezes inside the riser. This slow-start condition typically results in permanent damage and the need to rebuild the pump or at the very least replace the riser.

Like a Launder, Only Better!
A launder is used to transport molten metal. The basic construction of a launder is a steel trough lined with refractory material to insulate the molten metal from the steel. (Insulating both thermally and chemically.) The molten metal will lose heat as gravity draws it down the launder. If the heat is lost too quickly, the metal will freeze in the launder. There are a number of factors that influence the rate of heat loss including:
