A hot isostatic press (HIP) from Quintus Technologies will enable Italy’s Flame Spray SpA, a thermal-spray coatings provider, to respond to growing demand for densification and heat treatment as additive manufacturing (AM) increasingly takes hold in aerospace parts production. The press will streamline the workflow by integrating the ability to stress relieve, HIP, heat treat and age parts in a single cycle. The combination of high pressure and heat treatment (HPHT) in one system enhances efficiency and reduces per-unit processing costs while generating savings in space, energy and infrastructure. Uniform rapid cooling (URC) capability minimizes thermal distortion and non-uniform grain growth, producing finished parts with optimal material properties.
Solar Manufacturing has been commissioned to design and build a vacuum furnace for Magnetic Shields Ltd. of Kent, England. According to the companies, it will be one of the largest horizontal vacuum furnaces in the United Kingdom. The furnace, which is being built with a SolarVac Polaris control system, will be designed to accommodate loads up to 48 inches wide x 48 inches high x 96 inches deep with a maximum weight of 5,000 pounds. Operating at a vacuum level of 10-5 Torr, it will be able to reach temperatures up to 2400°F (1315°C) and include a partial-pressure hydrogen gas process and an external quench system designed for negative pressure quenching.
From start to finish, the production of metal products is one of the most energy-intensive industries in the world. As a result, improving both energy and production efficiency, while also ensuring product quality, is likely at the top of any manufacturer’s to-do list.
Tenova LOI Thermprocess received an order from China’s Shougang Qian’an Electrical Vehicle Steel Co. for the heat-treatment portion (furnace system) for two annealing and coating lines (ACLs) for non-grain-oriented (NGO) electrical strip. The scope of the contract includes engineering, turnkey delivery of all furnace-related key components, supervision of assembly, commissioning and training. In addition to the electrical equipment belonging to the furnaces, the control components and the associated software and a mathematical furnace-management model will also be supplied.
In today’s society – with prevalent discussions regarding environmental impact, global warming and with many companies even tracking their carbon footprint on their websites – efficiency is certainly a hot topic.
Efficient is an adjective defined as “achieving maximum productivity with minimum wasted effort or expense.” Society as a whole typically strives to achieve and apply “efficiency” to all facets of life.
Can-Eng Furnaces International Ltd. received the final acceptance certificate from Indian steelmaker SAIL for a roller-hearth plate quench-and-temper system. It is designed to heat treat a wide range of plates from 0.25-4.0 inches (6-100 mm) thick x 118 inches (3,000 mm) wide up to 42.5 feet (13 meters) long in a variety of grades for commercial and non-commercial applications. With an overall line length of 400 feet (122 meters) and a restrained roller spray quench at the heart of the system, the heat-treatment process results in true flat plates with metallurgical properties that exceed contractual requirements. The auto-recuperative radiant-tube-fired atmosphere roller-hearth hardening furnace and direct-fired temper furnace run off coke-oven gas (COG), a byproduct of the steelmaking process.
