Cover Gas in Secondary Aluminum Melting
In the realm of secondary aluminum melting, refining, and recycling, the utilization of cover gas stands as a pivotal technique for enhancing process efficiency and product quality. Cover gas, essentially an inert gas blanket, serves to shield molten aluminum from the detrimental effects of atmospheric oxygen interaction, mitigating oxidation and dross formation.
Expertly Optimized Solutions
High Temperature Systems, Inc. partners with melt department managers, supervisors, and engineers to craft complete solutions and solve problems that are beyond the reach of industry off-the-shelf solutions. Drawing from our standard product lines and more than 50 years of experience, we can craft solutions unique to your applications and furnace implementations. These solutions encompass aluminum, zinc and lead operations from die casting to galvanizing.
Impeller Types and Purposes
We offer three different types of impellers for many of our molten metal pumps. (The impeller is the vaned wheel that spins inside the pump base.) The impeller and its interaction with the pump base (and base volute) largely determine the performance characteristics of a given pump design.
Circulate Continuously - Transfer on Demand
The ideal solution for these furnaces would be a single compact pump that performs both the circulation function and the transfer function. Such a pump would require a mechanism to redirect the output of the pump impeller to either a circulation nozzle or a transfer riser.
