A tempering furnace is a type of industrial oven designed to heat treat a ferrous metal product and increase its toughness. In metallurgical terms, the toughness of an alloy describes its capacity for elastic deformation and energy absorption before the material fractures. It is part of a complex relationship between a metal’s ductility and its strength, with high toughness values requiring a delicate intersection of the two. Typically, high strength materials are not ductile – and vice versa – but heat treating certain materials in a tempering furnace can unlock beneficial values on both axes of this mechanical dynamic. How…

Electric heater plates are ceramic heating elements used in the manufacture of industrial ovens and furnaces. They are simultaneously designed to heat the internal chamber of an oven with good uniformity, while insulating the sensitive mechanics and the exterior of industrial equipment. This is achieved by combining high-strength metal wiring with thermally-efficient ceramic materials, enabling electric heater plates to operate at temperatures exceeding 1200°C (2200°F). Electric heater plates are most commonly manufactured as flat profiles with grooves of varying lengths and widths to accommodate electrical wiring or coils. These wires, or the conductive element of the electric heater plate, are…

Furnace suppliers for the aerospace industry must be intrinsically aware of the stringent specifications of aero and astronautic end-products. Raw materials for aircraft fuselages and interior structures must be suitably hardened through various heat-treating processes to ensure that all components withstand the staunch requirements of inner-atmosphere flight. Strict certifications and compliances are in place across the world to ensure that aerospace materials operate to the best possible standards. Qualified furnace suppliers operate to numerous international standards, including: AS 9100; EN 9100; JISQ 9100. These categories determine the minimal functionalities of aviation vehicles to minimize danger or risk relating to component…

The primary component of ceramic fiber insulation is high-temperature insulation wool made from synthetic minerals capable of withstanding consistent temperatures exceeding 1200°C (2192°F). Before application however, this synthetic material must be densified, treated, and machined for various purposes. This post will explore the process of manufacturing ceramic fiber insulation in more detail: Forming Alumina Silicate Wool Thermcraft’s ceramic fiber insulation products are formed using industry-leading refractory ceramic fibers made from alumina silicate. These are manufactured by melting varying ratios of pure aluminum (AL2O3) and silicon (SiO2) in an industrial furnace. The melt is made to flow through an aperture at…
