INDUCTOHEAT BANYARD – YOUR EXTRUSION PARTNERS

Non-Ferrous Billet Heating

Xtruheat

Our non-ferrous billet heater solutions for extrusion utilise SCR thyristor or IGBT switching technology. We are dedicated to providing the customer with a well engineered, cost effective solution with a reliability of >99.9% - a figure unmatched by the competition and quantified by our customers. The switching technology in conjunction with our precise PLC temperature control principles ensures the extruder receives a repeatable accurate billet temperature (with taper as required) for quality improved extrusions. Taper heating is achieved using multiple control zones by the 'static' or 'dynamic' heating methods. New standard products for the extrusion market such as the Xtruheat and the Booster have been introduced in the last 18 months.

Booster

We have a unique induction coil manufacture process which provides greatly extended coil life (subject to cooling water quality) whilst optimising multi-layer efficiency - a factor paramount in the customers' eyes due to running cost considerations.

For copper and brass the rapid heating rates achievable by induction reduce oxide formation and surface burn-out of alloying elements for improved product quality.

Furthermore, we are able to deliver a complete log heater solution. Replacing a gas furnace with an induction log heater is a viable option for any extruder. Put simply, a base heater takes the log from ambient to 380-450°C range and later a taper heater takes the billet up to 480-550°C range. During the heating process the log is pushed forward at a constant speed (dynamic heating) and the base heater is designed such that the log will achieve its required temperature on reaching the end of the coil. From this position it is pushed forward into a hot shear and the required billet length cut off. The remainder of the log is then pushed back inside the base coil by an amount equivalent to that which has been sheared off.

Aluminium Tube Annealing

A highly reliable product has been developed using standard inverter technology for the in-line annealing of tube prior to drawing. The product will anneal, induction heat and water quench products from 11 mm to 28 mm at speeds of up to 800 mm/minute. Optimum grain growth size and tube hardness is guaranteed using the Inductoheat Banyard system.

Who should consider using Inductoheat Banyard heaters?

• Existing gas furnace extruders. The quality of taper gradients achieved within the aluminium alloys using Banyard induction heating methods cannot be matched by any other process, including water quench methods post gas heating and ring burners. Inductoheat Banyard's shock taper or nose heaters can be retrofitted to existing installations (even with space constraints) or provide the controlled taper heat after a gas multi-billet furnace.
• Consider, particularly with new press lines, what the real 'life cycle cost' is for the gas furnace. Whilst gas is cheaper per unit at face value, it is often the case after unplanned and planned maintenance that the costs outweigh those for induction in a surprisingly short timescale and this can de demonstrated.
• The advent of 'just-in-time' delivery and single billet batch runs is another reason why the flexible Inductoheat Banyard single billet heater is an excellent solution.
• Producers of high quality aluminium alloy extrusions benefit considerably from our specially designed zero friction, non-contact single billet heater.
   

For reliability and peace of mind, Inductoheat Banyard is the optimum choice.
