L&L Special Furnace Company received an order for a car-bottom furnace from a manufacturer of pipes, tubes and fittings located in the southeastern United States. The gas-fired furnace, scheduled for delivery in the fourth quarter of 2021, will be used for normalizing various steels and specialty alloys at temperatures up to 2200°F (1200°C). It will also be used to preheat, stress relieve and temper various steels and large pipe fittings. Working dimensions are 48 inches wide x 48 inches high x 120 inches deep, and uniformity of ±25°F (12.5°C) or better is expected throughout the work zone.
Can-Eng Furnaces International Ltd. has been awarded a contract to design and manufacture two 50,000-pound-capacity car-bottom furnaces for one of the world’s largest metals and mining companies. These custom-engineered furnaces will support the manufacture of critical metal hot-rolling machine components used in the production rolling of high value-added automotive steel sheet and plate. The two systems, although located side by side, will utilize completely independent control systems to allow flexibility for scheduling and maintenance. Both furnaces will be interconnected to the larger plant-wide system for data acquisition and trending capabilities.
Gasbarre Thermal Processing Systems built and commissioned a high-temperature car-bottom furnace for a manufacturer of excavating equipment based in the southern U.S. The furnace has a work zone of 84 inches wide x 144 inches long x 48 inches high with a 16,000-pound load capacity and an operating temperature range of 1000-2282°F (538-1250°C). It will be used for stress relieving, normalizing and other high-temperature processes. The furnace, which replaced an existing furnace, gives the manufacturer improved operating efficiency and higher-temperature processing capabilities.
Solar Atmospheres of Western PA commissioned a 20-foot-long car-bottom air furnace with a total load capacity of up to 30,000 pounds. The Class 2 furnace, built by Heat Treat Equipment Inc. of Canton, Mich., was installed and fully tested in Hermitage, Pa. The 60-inch-square x 240-inch hot zone passed the AMS 2750E temperature uniformity survey of +/- 10°F from temperatures of 300-1450°F. The furnace passed the survey on the first attempt and was put into production immediately.
Solar Atmospheres of Western PA invested in a new car-bottom air furnace. The 20-foot-long furnace, which will be delivered in July 2018, will be surveyed in accordance with AMS 2750 and is uniform within ±10°F (Class 2). It has a working zone that is 60 inches square x 240 inches long and will handle a workload up to 30,000 pounds. With a maximum operating temperature of 1400°F, the furnace will accommodate not only the tempering of large tool-steel components but also age hardening of 15-5 PH, 17-4 PH and nickel-based alloys.
