2 Power Supplies Upgrade Heat Treat System

/ BRAZING NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT

HTD Size-PR LogoA Pennsylvania heat treat supplier recently shipped and commissioned two power supplies used in a continuous brazing furnace for a tool manufacturing company. The new power supplies, rated 125 kW supply and 100 kW, were designed as direct replacements for a pair of existing, obsolete power supplies that continuously failed.

Magnetic Specialties, Inc's power supplies reduce furnace downtime and provide tighter regulation of the furnace temperature which delivers more consistent quality of the braze parts. The brazing furnace has silicon carbide heating elements, which increase in resistance as they age. To compensate for this, the output transformers feature a tapped secondary winding. As the elements age, the client can select a higher output voltage range via the tap switch. The client will use the metering feedback to know when the tap needs to be changed.

/ AEROSPACE HEAT TREAT, ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS

L&L Medium Sized High Temperature Box Furnace

A government military defense organization, located in the southeastern United States, bought a medium-sized high-temperature box furnace for military ceramic composite development. It will also help with research and development for various other components.

The furnace, built by L&L Special Furnace Co., Inc., has a working zone of 24” wide by 18” high by 36” deep and is rated for continuous operating temperatures up to 2500°F (1371°C). It is equipped with silicon carbide heating elements for high temperature operation and sealed from the inside out for use with inert “blanketing gas."

This furnace is controlled by a Honeywell program control and corresponding overtemperature protection.

Radiant Tube Manufacturer Completes 3-Phase Expansion

/ ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS, HEAT TREAT NEWS INDUSTRIES

Holland, NY:  One of North America’s leading high-temperature radiant tube manufacturers, INEX Incorporated, recently completed a three-phase building expansion nearly doubling the companies footprint in Holland, New York, 30 miles southeast of Buffalo. According to Mike Kasprzyk, president and owner of INEX, “we’re now able to meet the growing needs of our expanding customer base.”

The expansion included additional production, engineering, and shipping/receiving floor space as well as the addition of new manufacturing equipment and technologies to meet consistently increasing demand. The company’s high-temperature silicon/silicon-carbide (Si/SiC) radiant tubes are one alternative to conventional all-metal radiant tubes and tend to have long life cycles and a higher BTU output per square inch than traditional all-metal radiant tubes.

For more on this expansion, listen to an audio interview with Mike Kasprzyk conducted by Heat Treat Today publisher DougGlenn by clicking here.

Magnesium and silicon carbide recipe results in lightweight metal with record strength

Magnesium has a number of potential advantages when it comes to engineering. It is considered the lightest of structural metals (those capable of bearing loads in buildings and cars) and it is the eighth most abundant element in the Earth’s crust. On the flipside, however, it is not as strong and durable as some of its counterparts. Scientists are now reporting to have overcome its main limitations by infusing it with silicon carbide nanoparticles to form a new type of super-strong composite material, which they claim may lead to lighter and more efficient airplanes, spacecraft and cars.
