High-temperature sintering has been proven to provide achievable increases in material properties when applied to conventional powder-metallurgy (PM) applications. As material properties and strength requirements increase, some thermal processors are transitioning from traditional sintering furnaces to high-temperature models. However, not all high-temperature sintering furnaces are created equal.

Williams Industrial Service is a single-source supplier for all your heat-treating needs. We produce all of the equipment that you require in-house. Our specially designed 57,000-square-foot facility allows us to build your heat-processing system from the pit up. This provides us the ability to control engineering standards and all aspects of construction for a timely delivery of your system.

Gasbarre Thermal Processing Systems manufactured and shipped a high-temperature pusher furnace to a supplier of specialty tungsten alloy products in the eastern United States. The furnace, which has operating temperature capabilities up to 2750°F (1510°C), is designed for high-temperature sintering. It is electrically heated using molybdenum elements and utilizes the latest in refractory materials for efficient operation. The pusher system processes trays 8 inches wide x 12 inches long under 100% hydrogen atmosphere and includes an automated return conveyor for effective loading and unloading. 

Otto Junker GmbH delivered a pusher furnace for heating and homogenizing aluminum ingot to Logan Aluminum Inc. in Russellville, Ky. Logan Aluminum manufactures flat-rolled aluminum sheet primarily used in the beverage market. In an effort to expand production, the company now operates the largest ingot furnace Otto Junker has ever supplied. The gas-fired furnace can simultaneously hold 32 ingots weighing up to 32 metric tons each, resulting in a charge weight of over 1,000 metric tons. High-convection technology ensures fast heating and cooling with short cycle times and low energy consumption.

Armil CFS Inc. shipped a hydraulic pusher furnace designed to burn out and preheat investment-casting molds to a Midwest manufacturer of marine propulsion components. The furnace, which includes an automated tray extraction system and return conveyor, is designed to push a 48-inch-wide tray holding investment-casting molds up to 18 inches high. The combustion system is configured to promote clean firing of ceramic molds at temperatures up to 2150°F (1177°C).

Armil CFS Inc. shipped a natural-gas-fired pusher furnace to a European manufacturer of investment castings for the medical industry. The two-row, high-production furnace will be used for the burnout and preheating of investment casting molds. It has an operating temperature range of 1650-2100°F (900-1150°C). Residual wax will be consumed within the furnace chamber, eliminating the need for an afterburner. A recuperative combustion system will utilize a series of medium-velocity burners and a cross-flow recuperator operating in three zones of control.
