Embodiment

[0034] Testing was performed using a J50GI pump available from Pyrotek, Inc, Metalullics Systems Division (Aurora, Ohio). The pump includes a gas injection tube plug fitted with a standard injection tube. Shorten the tube to 12" (12 inches). Thread the 0.5" ID to accept a steel tee adapter. Tygon tubing connects the adapter to an adjustable flow meter (0-20SCFM). The T-adapter is also fitted with a second, smaller tube adapter. A smaller adapter connects to the pressure sensing device.

[0035] The motor speed is controlled by a variable frequency drive. The test setup provides the opportunity to set the pump speed at any desired speed. Select the airflow and record the pressure at the point of pickup. Datasets were recorded at various speeds for different blocking configurations. The "choke" is constructed of foam and secured to the discharge of the pump with bolts and washers.

[0036] In addition, the water tank is equipped with a viewing window. This allows visual ...

Abstract

A molten metal pump comprises a base defining a pumping chamber, an impeller disposed within said pumping chamber, an outlet passage extending from said pumping chamber, the outlet passage being defined by opposed top and bottom walls and opposed side walls, wherein the top and side walls terminate at an intersection with a boundary of the base and the bottom wall terminates inward from the boundary.

Description

Background technique [0001] In the non-ferrous metal industry, scrap recycling has become a way of economic life. In fact, environmental concerns and environmental protection have long driven efforts towards scrap recycling, with the recycling of aluminum, copper, zinc, lead and tin taking a firm place in the market. [0002] It is known to provide a holding portion of a furnace in which molten metal is heated within an enclosure, wherein the controlled combustion suppresses oxidation of the molten metal. Metal solids are introduced into a well connected to the holding section of the furnace and molten metal is returned to the holding section to maintain the temperature of the metal in the well and to deliver fresh metal to the holding section. During the processing of molten material, it is often necessary to transfer the molten material from one vessel to another or circulate the molten material within the vessel. Pumps for handling molten materials are often used for thes...
