Imagine water being poured into a glass quickly and carelessly: as the glass fills, erratic swirls, eddies, and bubbles appear in the liquid. That chaotic movement – created by inconsistencies in the velocity of the pour – indicates the flow of water into the glass is turbulent. This so-called “turbulent flow,” isn’t restricted to hastily … How Foundries Can Reduce Turbulent Flow with Electromagnetic Pumps
Blistering heat. Bubbling, sparking vats of molten metal. The ever-present risk of dangerous spills or even explosions. For foundry line workers, it’s all just another day at the office. The work performed by foundry workers – those who hand ladle, in particular – can be a dangerous and physically demanding grind. Employees work long days, … How to Increase Foundry Worker Retention with Electromagnetic Pumps
The demands placed on both low and high tolerance foundries can result in a bit of a Catch-22. Foundries are expected to improve throughput, eliminate downtime and reduce scrap rates. Those goals can be difficult to achieve in even the most ideal circumstances – but can seem nearly impossible in the standard foundry environment. The … The Top 7 Reasons Foundries Use Electromagnetic Pumps
Abstract The present demand for greatly improved productivity and quality of aluminum castings has brought many developments and continues to force critical evaluation of our manufacturing processes. Handling and pouring of molten metal are two areas where new ideas are being introduced to achieve these goals. Aluminum is easily damaged when in the liquid state, … Controlled Pouring for Aluminum Castings
The low pressure casting technique has long been known to produce high quality aluminum castings, but the process has also been plagued by some persistent problems. Many of these problems can be eliminated through the use of an electromagnetic pump as opposed to the standard pressurized furnace. The pressurized furnace system has several disadvantages which … Pressurized Furnace vs. EM Pump
In the science of Physics, Laplace’s Law describes the interaction between a magnetic field and an electric current when they are applied at right angles to each other and to a conductor of electricity. This Law explains how induction motors function and is better known as Fleming’s Left Hand Rule, in which the thumb, forefinger … Electromagnetic Pump Principles
Aluminum and other light metal casting foundries have traditionally used the technique of pouring the molten metal into molds from a ladle, relying on gravity to fill the small spaces in the mold cavity. This must be done very carefully so the molten metal does not experience oxidizing turbulence. The nature of molten aluminum as … What Is Electromagnetic Pumping?
