Ipsen answers maintenance questions for vacuum heat treating systems
February 10, 2016
Source:
Ipsen, Cherry Valley, Ill., reports that its "Finding Leaks in Your Vacuum Furnace" blog series takes a close look at how to determine whether the furnace or the pumping system is the root cause of vacuum-related issues. For example, some people might immediately assume something is wrong with the furnace when it begins to present signs of outgassing, dirty parts, performance issues, etc.
While it's possible that the furnace could be the source of the problem, it is important to avoid wasting valuable time going through all the steps of leak checking the furnace only to realize that actually something is wrong with the pumping system. Therefore, Ipsen experts outlined a few simple steps for determining whether the furnace or the pumping system is the guilty party in their newest "Finding Leaks in Your Vacuum Furnace" blog post; find out what these steps are at http://bit.ly/LeakCheck-10.
Ipsen's blog, "The Ipsen," Harold, also features informative videos, expert tips, throwback photos, and useful resources, such as A Daily Checklist for Preventive Maintenance and their ongoing series, A Look Inside the Furnace (which examines hot zone types, best practices and maintenance).
Focused on sharing tips of the trade, as well as breaking down technical and complex material, this blog provides readers with valuable, up-to-date thermal processing information. Be sure to check out Ipsen's other posts and how-to videos on their blog, The Ipsen, Harold.

One Minute Mentor: Heat Treatment of a Premium Grade H13 Die
February 4, 2016
Source:
The graph shows a continuous cooling test in which the austenitizing temperature was approximately 1040°C (1900°F). It shows the effect of intermediate cooling rates on the microstructure and toughness of H13 tool steel austenitized at 1075°C (1970°F). (a) Continuous cooling transformation (CCT diagram) shows variation in microstructure with varying cooling rates. (b) Variation in toughness as a function of carbides ejected from austenite. Hardness was maintained at a constant value.
Hot-work die steels containing 5% Cr are normally used (H13 is the most common in the United States) because they have:
• A good combination of toughness and strength for safety and service
• Good hardenability in thick sections
• Good hot hardness and strength to resist cyclic stressing at operating temperatures up to 400 °C (750 °F)
• Good resistance to tempering during service that gradually lowers the surface hardness and the fatigue strength
Carbide precipitation, other than that produced during tempering, is known to be deleterious to the fatigue life of H13 tool steel. Fast quenching rates required to suppress intermediate precipitation of carbides (such as proeutectoid grain-boundary carbide, pearlite, or bainite) also produce large thermal gradients within the tool. Fast quenching rates can cause distortion or even cracking. The larger the tool, the greater the risk of cracking.

Steel forgings for windmills to be produced in joint venture
February 3, 2016
Source:
Sumitomo Corp., Japan, and the Japan Steel Works have formed a joint venture with Gerdau Steel, Brazil, to manufacture forged steel products for wind power generation. Gerdau is the largest long steel manufacturer in Brazil. Production of these forged parts is expected to begin in 2017.
The joint venture (tentative name "Gerdau Summit"), in addition to the existing business of Gerdau, plans to expand the business into the production and sale of wind power generation forged products.
Currently, the Brazilian government's policy is to almost double the ratio of wind power generation from a national total power supply of 6% in 2015 to 11% in 2024, in order to meet future electricity demand. To achieve this goal, the government provides support for wind power generation projects and encourages domestic manufacturing of wind power generation-related parts.
"We're working to transform Gerdau into a more efficient and profitable company, given the current and future challenges of the global steel industry," said Gerdau CEO Andre B. Gerdau Johannpeter. "We're seeking to join forces with partners who have recognized experience in their industries in order to create new business opportunities. With Sumitomo Corporation and JSW, we will develop higher-value products for our clients, which will enable them to generate higher profit margins."
JSW has long been leading the world's forging industry with its manufacturing technologies, mainly in the energy field such as power generation. Sumitomo also has significant experience and knowledge within the renewable energy and wind-related business, which has been cultivated through many infrastructure projects and related parts sales respectively. By bringing the strengths of these two companies together with Gerdau's strong production base,"Gerdau Summit" will focus on the production and sale of forged products for wind power generation in the Latin American market with a focus on Brazil. JSW has plenty of experiences to transfer its forging and casting techniques to foreign countries. Based on such experiences, JSW launches its overseas joint venture project for the first time in the forging and casting field.

CEC supplies chain conveyor solution furnace for heat treating aluminum die castings
Source:
Consolidated Engineering Co. (CEC), Kennesaw, Ga., announces that it has received a purchase order for a four-zone natural gas-fired chain conveyor solution furnace for the T4 treatment of aluminum high-pressure die castings. To be installed in a casting facility in Mexico, the furnace will heat treat automobile shock towers. The system includes a solution furnace, air quench, age oven, cool unit, and four load/unload gantry cranes, and will process the castings at a rate of 90 castings per hour.
High pressure die casting, in which molten aluminum is injected into a metal die, now accounts for more than half of all aluminum castings worldwide. This manufacturing method has shown to be particularly suitable for making complex part shapes for automobiles.
CEC manufactures a variety of industrial chain furnaces that allow for efficient conveyance of the product during heat treatment. A chain type furnace may describe one of several methods moving the casting or forging through the furnace.
The chain furnace concept allows the product to go directly into the furnace without a basket, rack, or tray. Wasted heat for heating up the tray or basket is eliminated. The processed part can come directly from the casting dies or the forging press without cool-down. CEC can automate a foundry or forge shop to the current state of the art for heat treatment with its broad array of chain furnace configurations.
