Tenova LOI Thermprocess received an order from Russian’s JSC Pervouralsk Pipe Plant for a roller-hearth continuous furnace system for bright annealing stainless steel pipes in a 100% hydrogen atmosphere. The heat-treatment system is designed as a roller-hearth furnace for the bright annealing of 2,000 kg/hour of austenitic stainless steel and nickel-based alloy pipes. The solution annealing of these high-alloy steel grades is carried out in the temperature range of 2012-2192°F (1100-1200°C). The tubes are heat treated in this continuously operating system using a 100% hydrogen atmosphere as process gas.
Lindberg/MPH shipped an electrically heated pit furnace to a manufacturer in the power industry. The furnace is designed with a maximum operating temperature of 1750°F and gross workload of 1,600 pounds. It can accommodate a work basket 25 inches in diameter and 48 inches deep. A retort minimizes atmosphere consumption and furnace conditioning time between loads. The cover lid utilizes an electrically operated boom lift, which provides ease of loading and unloading. An upper furnace fence guard was also installed to provide added safety.
Nitrex, a global provider of fully integrated heat-treating solutions and technologies, acquired G-M Enterprises, a manufacturer of vacuum furnaces. The acquisition is in line with Nitrex’s strategy to further expand its heat-treatment solutions while strengthening its products portfolio. For the past 30 years, Corona, Calif.-based G-M Enterprises has earned a reputation as a leading technological supplier of vacuum furnaces for customers in the aerospace, power-generation, energy, MIM and commercial heat-treating industries. According to Montreal-based Nitrex, the acquisition represents a great fit because both companies share the same goal of providing technologies that improve customer workflow and efficiency while maximizing the life span and quality of engineered parts and components.
Over the years, the heat-treatment industry has seen a number of truly innovative technology advancements – the oxygen probe and the adaptation of process simulators for recipe development being perhaps the most impactful to date.
The dates for the next staging of Thermprocess, GIFA, METEC and Newcast have been set. The international leading trade fairs for metallurgy and foundry technology will he held June 12-16, 2023, at the fairgrounds in Düsseldorf, Germany. The trade fair’s duration of five days remains the same, but the weekdays have changed. The trade-fair quartet will start on a Monday and end on Friday.
Bodycote entered into an agreement to acquire Ellison Surface Technologies to create one of the world’s largest providers of thermal-spray and engineered-coating surface technology services to the aerospace industry. Ellison, which is headquartered in Mason, Ohio, will be integrated into Bodycote’s surface technology and aerospace business. The synergies between the companies will enhance the combined organization’s ability to deliver solutions that address aerospace customers’ heat-treatment and specialist thermal-processing requirements.
