Vacuum heat treat operations expand for ZDT Glimag, an entity providing services in the field of vacuum heat treatment, laboratory tests, and production of parts for mining machines.
The addition of this Vector® vacuum furnace will be the third vacuum furnace from SECO/WARWICK. The current design has an operating space of 600 x 600 x 900 mm and will be equipped with numerous options to allow a wide range of heat treatment processes for various steel grades. Main processes will include vacuum brazing, FineCarb® vacuum carburizing, and high-pressure hardening. The design of the chamber size will enable efficient heat treatment of large packages of test and research elements.
The efficiency of processes is also influenced by the ability to cool at 15 bar (which, unlike the old furnaces, eliminates the need to wash the parts after the process). In combination with inverter control, the system also helps reduce power consumption peaks, which are so problematic today. Another big advantage is low heat losses and appropriate temperature uniformity in the heating chamber, which is resistant to rapid wear and is easy to use and service.

Maciej Korecki, VP of the Vacuum Furnace Segment in the SECO/WARWICK Group, comments on ZDT Glimag saying, “It is a center very well oriented in the metal heat treatment industry, constantly testing new, innovative solutions that in turn make the mining industry more efficient. The new Vector will introduce revolutionary changes in the hardening plant, introducing innovation and a very wide range of precise processes.”
The Vector® line vacuum furnaces can be used in most standard vacuum carburizing, hardening, tempering, annealing, supersaturation, and brazing processes. At the same time, the solution can be adapted to the recipient’s individual requirements, and therefore to a specific industry, an attribute necessary for research centers that test innovative solutions for external customers.
The solution‘s characteristic features are convection heating, i.e., a system improving the heat transfer efficiency when heating at lower temperatures, and directional cooling, which allows complex, flimsy, and long elements to be cooled in various ways, minimizing their deformations. An additional advantage is the vacuum carburizing option, which allows users to carry out precise processes to increase the steel surface hardness (carburizing) during the entire thermal process.
The original press release from SECO/WARWICK Group is available here.
Nucor-Yamato Steel Company beam mill in Blytheville, AR, will expand their in-house heat treat with 180-shtph walking-beam furnace, as well as ancillary upstream & downstream material handling equipment.

This configuration provides precision performance in vacuum, ensuring steel detail surfaces are protected, and the ability to carry out hardening processes through the use of high cooling gas pressures (15 bar).
The small vacuum furnace will have a working space of 400x400x600 mm. With a round heating chamber, the furnace, despite its small size, can be used to test and perform research on many sizes of parts including work with large dimensions.
Says Sławomir Woźniak, CEO of the SECO/WARWICK Group, "We cooperate with scientific institutions all over the world because we are aware that industry development depends on their work. Many groundbreaking discoveries have already been made, but I am sure that many more are yet to come."
The R&D institute deals with methods of refining metal products by increasing their corrosion resistance and increasing mechanical properties, especially fatigue strength and resistance to wear in friction processes. The technological institute strives to disseminate and apply in practice the results of scientific research and development work, develops new technologies, and conducts service activities.

Marle Group, a global manufacturer of orthopedic prostheses, has expanded its heat treating potential with the acquisition of a new furnace. The furnace on order will be used for the heat treatment of cobalt implants.
This Vector® vacuum furnace, supplied by SECO/WARWICK, will provide the high temperatures, pure environment, temperature uniformity, and quick cooling necessary for the Cobalt alloy hardening process.

In the words of Antoine Eschbach of Marle Group, “The furnace we ordered solves the challenges faced by anyone who has to heat treat cobalt alloys in a production process. . . . Knee implantology is a field that is developing rapidly especially in developed countries, such as United States of America and in many European countries. Our mission is to create the highest quality implants which raise the living standard of people around the world, and the Vector furnace will help us to achieve this goal."
In order for cobalt alloys to be used in implantology, they must be deprived of their ferromagnetic properties. This shiny, hard metal loses this property only when it reaches a temperature higher than 1131°C/2067.8°F. Such a high temperature makes it necessary to use a vacuum furnace in the implant production process.
The solution on order uses two gases - nitrogen for cobalt hardening and argon to achieve purity of the process during heating. It is also equipped with a dew point sensor for each of the gases, thanks to which the phenomenon of water vapor condensation and, consequently, the possibility of the processed load’s surface oxidation is eliminated.
Also significant for the cobalt treatment process is also a quick cooling system based on a gas blower ensuring a maximum hardening pressure of 15 bar abs.

A European subcontractor for the automotive and racing industries as well as a partner for teams participating in Formula 1 races has acquired a second vacuum furnace.
The order from SECO/WARWICK includes a Vector® vacuum furnace with 15 bar abs high pressure gas quenching, and high vacuum (HV). The furnace will process engine and gear components for vehicles racing large-scale motorsport competitions.
This partner provides carburizing, and various heat treatment services for titanium, aluminum and precipitation hardening of alloys. These services must be of aviation quality within the demanding timeframes required by European F1 teams.
In the new SECO/WARWICK furnace, the customer will execute vacuum heat treatment of titanium and its alloys and will perform vacuum carburizing processes for steel elements. Titanium alloys are very strong materials, but at the same time soft and plastic, which makes them difficult to machine. Low thermal conductivity and density creates an environment where the cutting material is subject to a strong thermal load and tends to harden.
The FIA regulations for Formula 1 racing specify in detail what material a part must consist of and how it must be manufactured. Titanium or titanium alloys are used for many engine parts and suspensions because they have high toughness, strength, and ductility, and are corrosion resistant. Formula 1 car components must be manufactured precisely and safely in both prototype and small series production.
The purpose of this particular model of Vector furnace will be unique, as carburizing and hardening of parts such as gears for engines and transmissions for high-performance F1 sports cars are not the typical processes for which SECO/WARWICK supplies its furnaces.
Commenting on this order, Maciej Korecki, vice president of the Vacuum Segment at SECO/WARWICK, explained, "The vacuum furnace system which will be delivered to England has numerous options such as cryogenic processing, convection, FineCarb® vacuum carburizing, pre-nitriding for PreNitLPC® carburizing technology or low-pressure carbonitriding LPCN."
