A work Coil Positioning Table provides motorized adjustment of the mill set-up. The number of adjustment axes required depends on the pipe or tube production range and the mill configuration. Thermatool will gladly review your production requirements and recommend the best table for the application.

HF welded products, manufactured to API specifications for line pipe and oil well casing, require heat treatment in the weld zone. This process, known as seam annealing or normalizing is carried out to restore the grain structure in the weld zone to a finer structure which is equal to that of the parent metal. This refining process is done to prevent possible stress or corrosion cracking at the weld seam. Seam annealing units are available for inline and offline applications and for both longitudinally and spirally welded pipes. Recent advances in inductor design make it possible to seam normalize tubes as small as 0.75" (19.0 mm) and spiral pipe welds with any helix angle.

Unheated Tundish Pouring Systems are designed for foundries with a semi- continuous supply of metal and where alloy flexibility is a must. They are suitable for gray, malleable and ductile iron. Advantages include:

• Bottom pour stopper rod pouring to deliver clean metal from under the slag
• Efficiency of refractory lining system design to reduce metal temperature loss.

Inductotherm's Weld Annealer is designed to relieve the mechanical stresses in the strip after welding to prevent breakages due to work hardening of the weld for special high strength steels. This compact UNIWELD design also requires little line space.

Inductotherm individually selects and designs the components to manufacture custom induction heating systems to fit all our customer's needs.

Induction heating is perfectly adapted for rapid changes of the steel temperature during the thermal cycling in annealing furnaces. The induction heating equipment effectively “boosts” the capacity of the annealing furnace.

Inductotherm has also developed and patented a new
type of induction edge heating system by using an inductor
that automatically adjusts to a change of strip dimensions without any movement. This system can be added below the galvanneal heating assembly.

Several types of coating used to protect steel strip have appeared on the market during the last few years. Moreover,the demand for these coated materials is increasing so rapidly that coating lines must continually increase productivity.

• Induction heating systems with high -frequency inverters are able to achieve high power densities, reducing the heating time of strip and reducing the size of the drying furnace.

Modern tinning lines use high frequency “STATITRON” inverters for this application. The main advantages of these inverters in comparison with the old vacuum tube generator are: better electrical efficiency, safer and easier maintenance, and reduced dimensions. The reflow units using the new transistor inverters have even better efficiency than conduction type heating systems.

Premelt pots, available in both channel and coreless versions, may be used for:

• Alloying (e.g., Alu-Zinc alloys)
• Isolating the dross produced by melting, away from the coating process
• Acting as a buffer to minimize temperature variations in the coating pot due to ingot insertion
• Gas heated launders are also available for conveying molten metal from the premelt pot to the coating pot.

Melting systems built with the technology from Consarc Engineering, an Inductothermgroup company, the world’s leading vacuum system manufacturer.

Inductotherm offers a wide range of vacuum furnaces to meet the requirements of varied vacuum melting applications. These furnaces are designed specifically for operation under high vacuum environments and include vacuum-adapted construction methods and the industry’s most advanced coil and connector dielectric insulation technologies and procedures.
