In a business environment earmarked by intense competitive pressures, maintaining processing efficiencies can be the profitability difference. For heat-treating operations, improving efficiency and optimizing cost savings have long been an area of focus. But now there’s a viable, often- overlooked opportunity – Intelligent Process Cooling.
Founded in 1978 by William Pociask, P&L Heat Treating and Grinding began operations in a 2,500-square-foot building with only two employees, two austenitizing furnaces, two tempering furnaces and a rotary surface grinder.
L&L Special Furnace Co. Inc. shipped a floor-standing box furnace to a high-tech aerospace and associated components manufacturer located in the southeastern U.S. The furnace, which has a work zone measuring 120 inches wide x 48 inches high x 72 inches deep, will be used for processing aerospace parts and various thermal applications. It has a temperature gradient of ±20°F from 1100-2150°F using eight zones of temperature control with biasing to balance any differential in temperature gradients.
Just as we’ve done in the past with other topics, Industrial Heating will take a look at the most-viewed Vacuum/Surface Treating articles (in terms of page views) on our website. Data was collected for 12 months, from August 2018 to August 2019.
Alfa Romeo Racing, operated by Sauber Motorsport AG, selected Quintus Technologies as its hot isostatic pressing (HIP) partner. The Formula One team invested in a press with proprietary URQ technology, which allows heat treatment and cooling to be combined in a single process, known as high-pressure heat treatment (HPHT). HPHT and HIP are used for the consolidation and densification of metal, producing a maximum theoretical density, ductility and fatigue resistance in high-performance materials. This makes it ideal for ultrahigh-performance automotive applications.
Danieli Olivotto Ferrè started up a tube roller-hearth annealing furnace at Tenaris Tamsa in Veracruz, Mexico. The furnace is designed to treat steel tubes coming from cold or hot processing with a maximum throughput of 5 tons/hour. It is able to perform different heat-treatment cycles, including normalizing, annealing, tempering and stress relieving. The pipe to be treated has an OD range from 15-120 mm, thickness from 1.5-20 mm and length up to 16 meters (52.5 feet).
Delta H supplied a dual-chamber aerospace heat-treating (DCAHT) system to Sintavia, a Hollywood, Fla-based provider of additive-manufacturing services. The furnace features dual chambers operable to 1200°F and 500°F with precision control and temperature uniformity and a roll-away stainless steel quench tank. The DCAHT system qualifies as Class 2 (+/-10°F) per AMS 2750E and includes all controls, data-acquisition technology and spare-parts package to be in full compliance with all aerospace pyrometry standards, including Nadcap.
Bodycote recently held an official opening ceremony at its new heat-treatment facility in Prague, Czech Republic. The plant, now fully operational and supporting customer requirements, provides a range of heat-treatment services and will support the automotive and general industrial markets in the region.
North Carolina Governor Roy Cooper announced that Bharat Forge America Inc. will build an aluminum forging plant to manufacture automobile components in Lee County, N.C. The $127.3 million investment will create 304 jobs. The new facility will be part of a larger manufacturing center that will create as many as 460 jobs. According to Bharat Forge, the investment will help it create a strong global manufacturing footprint as part of its aluminum strategy.
Over the past few decades, the low-pressure “vacuum” carburizing process has proven time and time again to produce superior part quality.
October 14, 2019
The use of vacuum technology for carburizing has always shown the most potential for improving the manufacturing process by reducing both processing time and the number of manufacturing steps required to produce a part.
