Lindberg MPH, Riverside, Mich., has shipped an electrically heated, rod over-bend atmosphere box furnace capable of providing six different atmospheres to a company in the steel and mining industry. This is the second heat treating furnace of this kind that the customer has purchased, and the design is tailored for the customer's specific process.
The atmosphere system includes flow meters for nitrogen, hydrogen, argon, carbon monoxide, and carbon dioxide. An atmosphere saturator allows variation of the moisture dew point of the nitrogen that flows to the furnace chamber. The saturator tank is fabricated of 304 stainless steel. The dew point is controlled from a dew-point transmitter located in the nitrogen atmosphere line before entering the furnace chamber. Dew point is also monitored through a sample port located in the side of the furnace chamber. Maximum load capacity is 465 pounds at 2000°F.
The atmosphere box furnace has work chamber dimensions of 15x30x12 inches, and has a maximum temperature rating of 2000°F. The furnace is constructed with a gas-tight steel shell made from continuous-welded steel plate reinforced with structural steel members. The furnace door lifts up to provide access to the work chamber, and is sealed by metal to metal contact to eliminate gasket wear and maintenance.
The door is raised and lowered by an air cylinder with roller chain. A natural-gas flame curtain is provided for the door area, and is activated when the front door is opened to ignite exiting combustible atmosphere and minimize air infiltration back into the purge chamber. The furnace chamber is heated with a radiant heating system.
Six different atmospheres are available, including nitrogen, hydrogen, endothermic, argon, carbon monoxide, and carbon dioxide.
"At Lindberg MPH, we pride ourselves on having the experience to design our equipment to meet the most stringent requirements," says Kelley Shreve, Sales Representative. "This customer's process required the furnace to provide six different gas atmospheres. This is the second system we have shipped to them with this advanced atmosphere system."

Wisconsin Oven Corp., East Troy, Wis., has shipped two natural-gas-fired enhanced-duty walk-in batch ovens that are designed to dry the sand cores used in the casting of a variety of parts. The sand-core dryers have the capability to raise the temperature from 70 to 450°F, driving water and resin from 6000 pounds of sand cores and a 600-pound steel load car within two hours.
Work chamber dimensions are 10x8x20 inches, with a maximum temperature rating of 500°F. Guaranteed temperature uniformity of ±10°F at 500°F was documented with a nine-point temperature survey. The oven bodies are constructed of tongue-and-groove panel assemblies featuring Wisconsin Oven's patented high-efficiency panel seams that provide 25% better insulating efficiency.
"These sand core dryers were designed to maximize efficiency and decrease drying time of the cores," says David Burke, Sales Representative, Torrid Enterprises. "The customer is able to pour and dry more cores in less time than before, resulting in increased production."
The dryers were fully factory tested and adjusted prior to shipment. All safety interlocks were checked for proper operation and the equipment was operated at the normal and maximum operating temperatures. An extensive quality assurance check list was completed to ensure the equipment met all Wisconsin Oven quality standards.

The Center for Heat Treating Excellence at the Worcester Polytechnic Institute, Mass., announces that it has presented its Distinguished Service Award to Steve Ferdon. The award is granted to an individual who has made significant, commendable, and long-standing contributions to the promotion of CHTE. A member of the ASM Heat Treating Society, Mr. Ferdon is the Director of Global Engineering Technology in the Fuel Systems Business Unit at global power leader Cummins Inc.
A member of CHTE since 2010, he has served as chair of its board of directors since 2012. His leadership at CHTE has contributed to mentoring the next generation of engineers, formalizing industrial membership governance of the board of directors, and sharing technical knowledge of heat treating applications with members.
Mr. Ferdon received the award at a formal ceremony recently during CHTE's biennial meeting on the WPI campus. "I am surprised and humbled by this recognition from the CHTE membership," he said. "Every year, I look forward to the spring and fall CHTE meetings, and the energizing collaboration with this unique group of talented, experienced, and highly practical technical leaders."
"Steve has impacted the advancement of CHTE," said Richard Sisson, George F. Fuller professor of Mechanical Engineering at WPI and technical director of CHTE. "From a technical standpoint, he brings a broad perspective to the industry. Cummins works with an extensive network of heat treating service providers from all over the world, applying multiple processes for ferrous alloys, and he shares a great deal of what Cummins has learned with our industrial members."
Prof. Sisson also noted Mr. Ferdon's efforts to bring the next generation of engineers to the meetings, where they can learn practical experience from industry leaders.
Steve received the Outstanding Materials Science Engineer Award from Purdue University's School of Materials Engineering in 1998, and is on the school's advisory committee. He holds six patents, is a Licensed Professional Engineer, and is a member of the AISI Bar Steel Fatigue Property Consortium Steering Committee. He began his career at Indiana-based Cummins in 1992 as a technical specialist in materials engineering.

Can-Eng Furnaces International Ltd., Niagara Falls, Ontario, has been awarded a contract to design and build a 1500 lb/hr mesh belt furnace system for the austenitizing and molten salt quenching of unique components for drivetrain systems. This contract was awarded by a repeat Mexico-based client who has purchased several Can-Eng multi-facility heat treatment lines.
The system incorporates several technological advancements for continuous atmosphere processing of products requiring carbon diffusion and quenching by a molten salt system. The new austempering system includes automated bin-dumping loading, mesh belt atmosphere hardening furnace, salt quench, post quench wash and rinse system, mesh belt temper oven, and endothermic gas generator.
This new project is a result of Can-Eng's commitment to its customer's success, years of teamwork, and mutual cooperation, yielding a custom engineering project integrating the customer's focused needs with Can-Eng's robust Continuous Mesh Belt Heat Treatment System technology.
The project is scheduled to be commissioned early 2018 in Mexico's centralized automotive manufacturing corridor. Can-Eng's mesh belt heat treatment design team continues to focus globally on the design and development of mesh belt heat treatment technology, servicing the increasingly stringent and demanding global automotive industry.

Source:
Japan's National Institute for Materials Science and Nagaoka University of Technology announce development of a high-strength magnesium sheet alloy that has excellent formability comparable to that of the aluminum sheet currently used in body panels of some automobiles. The alloy is composed of only common metals, and is expected to be a low-cost lightweight sheet metal for automotive applications.
Magnesium alloys are roughly 75% lighter than steels and 33% lighter than aluminum alloys. However, virtually no magnesium alloys are used in automotive bodies because of their high processing cost originating from the poor formability and low strength of magnesium sheet alloys.
The research team recently developed a new age-hardenable magnesium alloy: Mg-1.1Al-0.3Ca-0.2Mn-0.3Zn, named AXMZ1000. The newly developed alloy has excellent room-temperature formability comparable to that of medium-strength aluminum alloys. In addition, the new alloy is 1.5 to 2.0 times stronger than the aluminum alloy.
The excellent formability was achieved by adding very small amounts of zinc and manganese, which led to the formation of fine grain structures. The high strength was achieved by adding aluminum and calcium, which induced the strengthening of the alloy by the formation of atomic clusters.
The newly developed alloy is composed of only common metals, so the material cost is not expensive. Also, it can be rolled into sheets by simple processes and heat treatments typical for aluminum alloys. The alloy overcomes the long-standing issues for magnesium namely, low strength and poor room temperature formability. As the processing cost of the new material is expected to be low, there is good potential for practical applications in automotive bodies or casing of notebook computers and cell phones.
