This year’s show includes a VIP-guided industry tour, as well as student/emerging professionals initiatives, including free college student registration, Fluxtrol Student Research Competition, and the ASM Heat Treating Society Strong Bar Student Competition. Heat Treat 2023 is colocated with Motion + Power Technology Expo 2023 with access to additional exhibitors. The event takes place October 17–19, 2023 at Huntington Place in Detroit.

The largest of its kind in North America, the Heat Treat Conference and Expo bridges the gap between research with industry—bringing together heat-treating professionals, materials experts, global innovators, researchers, influencers, and decision-makers from around the globe. Below are a few booth previews along with a sidebar featuring some select networking and educational opportunities to look out for.

SECO/Vacuum—Booth 2101

At the ASM Heat Treat Show, SECO/Vacuum will feature technologies for “the future of heat treating”:

Vector Single-Chamber High-Pressure Gas Quench Vacuum Furnace

Vector is SECO/Vacuum’s single-chamber gas quenching vacuum furnace using high-pressure quench (2 to 25 bar) which can be applied to a wide variety of heat-treating processes and applications. It provides important capabilities for producing high uniformity in heat-treated parts, high consistency in workloads, and high speeds in batch processing with low consumption of power and process gases.

Casemaster Evolution Multichamber Gas or Oil Quench Vacuum Furnace

SECO/Vacuum offers two configurations of its CaseMaster Evolution. The two-chamber furnace, called D type, is a dual-chamber furnace with one chamber for vacuum heat processing and a second chamber for oil or gas quenching. The three-chamber furnace, called T type, provides the same chambers as the D type plus a third pre-heating (and/or pre-oxidation chamber) which increases productivity through semi-continuous batch processing. In the three-chamber approach SECO/Vacuum’s PreNitLPC process can be added for even higher productivity.

4D Quench Single-Piece Flow Vacuum Furnace

SECO/Vacuum 4D Quench for single-piece quenching with distortion control and prediction.

SECO/Vacuum’s 4D Quench furnace is a vacuum heat treatment solution for single-piece quenching with distortion control and prediction. It is designed to heat or re-heat products such as gears on a single conveyor deck. It consists of a vacuum heating chamber and a high-pressure nitrogen quench chamber equipped with transportation mechanisms. It enables customers to replace oil quenching with a clean, environmentally friendly, cost-effective nitrogen quenching technology. 4D Quench was designed for those who want to significantly increase the production quality and economy of high-volume gears and power transmission components to produce totally uniform parts in a completely hands-free environment.

Pit-LPC Vacuum Furnace

The new SECO/Vacuum Pit-LPC vacuum furnace.
 

The new Pit-LPC vacuum furnace from SECO/Vacuum is another innovation designed for clean, uniform processing of large or parts requiring deep case depths. As a modern alternative to atmosphere furnaces, the Pit LPC can reduce heat treating costs and improve production while improving the environment by operating in vacuum at higher temperatures than atmosphere furnaces can achieve. The Pit LPC also increases heat treater’s production throughput without purchasing additional equipment, since a single Pit-LPC furnace is equivalent to the capacity of three atmosphere furnaces, and it can be reconfigured to fit into the space of an existing atmosphere furnace. Additionally, a single vacuum furnace provides more capability since it can handle gas carburizing on larger and longer workpieces.

The LPC vacuum Pit furnace is perfect for manufacturers carburizing large or long elements such as gears, bearings, drilling tools and other elements requiring thick case depths and it is a great furnace for companies who want to increase their production capacity without purchasing additional equipment (1 Pit LPC = 3 atmosphere furnaces) or save space by replacing three machines with one that fits into the same space as one.

AFC/Holcroft—Booth 2219

Thermal processing is critical to producing the materials of modern life, yet they are unavoidably energy-intensive. But that doesn’t mean that heat treatment systems are impervious to ways to reduce their environmental impact. In fact, there are already many climate-aware improvements to traditional heat treatment systems that can be implemented, today. AFC-Holcroft is continually developing solutions to lessen the heat treatment carbon footprint and offers many forward-thinking ways to help safeguard the environment. In addition to their newly renovated manufacturing and offices reducing their own footprint—their Green Equipment Initiatives encompass options that can offer specific benefits towards energy savings, operating efficiencies, environmental safeguards, reduced carbon footprint, and general climate protection.

When it comes to the manufacturing of complex components such as gears, controlling distortion is a difficult, but necessary consideration for reducing the post-heat treat grinding process. There are opportunities to use various heat-treating processes to help reduce distortion and thereby reduce the overall grinding time, resulting in lower manufacturing costs and improvements in overall quality—but where are those opportunities? What is the best choice for your gear manufacturing operation?

AFC Holcroft UBQA (Universal Batch Quench—Austemper) System.

AFC-Holcroft uses molten salt during the quench portion of the heat-treating process in their UBQA (Universal Batch Quench—Austemper) System, which can be an effective, safe, and environmentally friendly solution to help overcome the problem of part distortion resulting in the quench process.

Salt quench systems are playing a major role in the next generation of IC powertrains, the xEV market, and industrial power transmission systems worldwide. AFC-Holcroft’s proven designs have been adopted by major multinational corporations across the globe, with greater acceptance than ever before.

Gasbarre Thermal Processing Systems—Booth 1928

Gasbarre Thermal Processing Systems’ continuous vacuum furnaces utilize the latest in control technology and offer repeatability and modular flexibility to meet the needs of virtually any vacuum heat-treating process. With temperature capabilities up to 2,650°F, they are designed to meet AMS 2750G requirements with uniformity up to Class 2 (±10°F) and instrumentation configuration Types D and E. They can be equipped with oil or gas quenching modules with gas pressure capabilities up to 10 bar, making them ideal for hardening applications. Modular equipment design allows low-pressure carburizing dwell times and index rates to be fine-tuned to meet process and production requirements, optimizing the return on value for your investment.

In addition to their robust design and modular flexibility, Gasbarre’s continuous vacuum furnaces offer several unique advantages over other types of vacuum heat treat equipment. Concurrent processing reduces the effective duration of the heat-treating cycle by eliminating work staging and vacuum pumping from floor-to-floor time. The resulting higher throughput allows for smaller load sizes which help overcome challenges with uniformity and repeatability associated with larger workloads required to achieve production rates in batch equipment.

Because heating and cooling are performed in dedicated sections of the furnace, thermal efficiency is dramatically improved over batch-style furnaces where the entire insulation assembly must be heated and cooled every cycle. Similarly, dedicated sections of the furnace reduce process gas requirements for cooling and partial pressure. In addition to reduced utility consumption, the lack of thermal cycling and oxygen exposure dramatically improves the life of refractory consumables within the furnace, reducing maintenance costs and downtime.

Continuous vacuum isn’t right for every gear-treating process which is why Gasbarre Thermal Processing Systems designs, manufactures, and services a full line of thermal processing equipment for virtually any process. Gasbarre’s offering includes continuous and batch atmosphere and vacuum equipment, serving customers in the automotive, aerospace, industrial equipment, energy, and commercial heat-treating industries.

Gasbarre provides products and services that combine value and design flexibility through knowledge and understanding of your process. For each piece of equipment, Gasbarre takes a 360-degree approach. From sales and applications engineering to equipment design, manufacturing, commissioning, and aftermarket support, Gasbarre’s team of engineers, metallurgists, and technicians aims to understand your process from all angles.
